#LessonHrTypeObjectiveActivitiesMaterialsCheck
1Hatchery Systems Overview and Facility Safety14theoryStudents will identify the major components of flow-through and recirculating hatchery systems, explain the function of each, and apply facility-specific safety rules including chemical handling, electrical hazards near water, and lockout/tagout for pumps and aeration equipment.
  1. Guided facility walk-through: students sketch a floor-plan diagram labeling sump tanks, header tanks, UV sterilizers, biofilters, pumps, aeration blowers, and emergency oxygen manifolds, then compare with an instructor-provided reference diagram.
  2. Tabletop hazard hunt: pairs of students review a hatchery photo set and list every visible or implied hazard (open electrical panels near water, unlabeled chemical containers, missing drain covers), then rank by severity using the OSHA hierarchy of controls.
  3. Lockout/tagout drill: using a training-tagged pump assembly, each student demonstrates applying an energy-isolation lock and tag, verifying zero-energy state, and completing the log entry before the instructor validates and signs off.
Facility floor-plan blanks, OSHA 29 CFR 1910.147 lockout/tagout reference card, personal lock sets, training pump assembly, PPE (chemical-splash goggles, nitrile gloves, rubber boots), hatchery operations manual excerptStudent-drawn floor plan must correctly label at least 12 of 15 components; hazard list must include all five instructor-key hazards; lockout/tagout drill scored on a 10-step checklist — pass requires 9/10 steps performed correctly without prompting.
2Water Delivery and Recirculating Aquaculture Systems (RAS)20labStudents will operate pumps, valves, and biofilter units in a functioning RAS, adjust flow rates to target specifications, and perform routine mechanical checks including impeller inspection and airline clearing.
  1. Flow-rate calibration exercise: students use a graduated bucket and stopwatch to measure actual flow at six standpipes in the larval room, then adjust gate valves to bring each within 10% of the posted target flow, recording before-and-after measurements.
  2. Biofilter backwash: students follow the written SOP to isolate a bead or drum biofilter, perform a backwash cycle, collect a pre- and post-backwash water sample for turbidity comparison, and record findings in the lab log.
  3. Simulated pump failure response: instructor cuts power to a header pump; students execute the emergency response SOP—switching to backup pump, checking alarm panel, notifying the hatchery manager, and documenting the event—within a five-minute window.
RAS training unit or operational hatchery RAS, graduated 5-gallon buckets, stopwatches, turbidity meter, gate valves, pump curve charts, Pentair or equivalent pump manuals, emergency response SOP cards, lab log notebooksAll six standpipe flows adjusted to within 10% of target; backwash SOP completed in correct sequence with zero skipped steps; emergency response completed within five minutes — all three criteria must be met to pass.

  1. Daily parameter sweep: each student independently samples three tanks (larval, broodstock, live-feed algae) using a multi-parameter meter and a colorimetric ammonia kit, then enters all values in the production log within 30 minutes of sampling.
  2. Spike-and-correct scenario: instructor adds ammonium chloride to a demonstration tank to elevate TAN above the alarm threshold; students diagnose the problem using their data, propose corrective actions (water exchange, feeding reduction, aeration increase), and calculate the volume of fresh seawater exchange needed to dilute TAN to a safe level.
  3. Meter maintenance lab: students calibrate a DO meter with air-saturation method, a pH meter with two-point buffer calibration, and a refractometer with distilled-water zero, recording calibration data and noting any out-of-range sensor readings.

4Broodstock Management and Conditioning16theoryStudents will describe the nutritional, photoperiod, and temperature conditioning protocols used to bring broodstock of at least two species to reproductive readiness, and complete a broodstock health and feeding record for a four-week conditioning cycle.
  1. Case-study reading: students read two peer-reviewed or industry extension articles on broodstock conditioning (one finfish, one bivalve or shrimp) and produce a one-page summary table comparing key parameters—temperature ramp schedule, photoperiod, feed type and ration, and target fecundity outcome.
  2. Broodstock record construction: using a data set of mock fish weights, condition scores, and observed behaviors provided by the instructor, students build a four-week conditioning log spreadsheet with calculated feed-ration values and flag any entry that falls outside protocol thresholds.
  3. Comparative species discussion: small groups each research a different commercially relevant species (e.g., red drum, Pacific oyster, white shrimp, Atlantic salmon) and present a five-minute overview of its broodstock requirements to the class, followed by class Q&A.
Broodstock conditioning articles (NOAA Fisheries extension or equivalent), species data sheets, spreadsheet software, mock conditioning data sets, whiteboard, Stickney's 'Aquaculture: An Introductory Text' or equivalent textComparison table must accurately represent all key parameters from both articles with no factual errors; broodstock log must have correct feed-ration calculations (within 5%) and all threshold flags correctly identified — pass requires 80% accuracy across both tasks.
5Spawning Induction and Egg Collection18demoStudents will observe and assist with at least one spawning event—using natural photoperiod cuing, temperature manipulation, or strip spawning depending on species availability—and correctly collect, rinse, and count eggs or assess fertilization rate.
  1. Instructor-led spawning demonstration: instructor performs or directs a spawning procedure (e.g., temperature shock induction for oysters or gentle strip-spawning of a finfish), narrating each step while students complete a structured observation checklist noting timing, equipment, and outcomes.
  2. Fertilization rate assessment: students take a subsample of fertilized eggs at 15 minutes post-fertilization, prepare a wet mount, examine under a stereo microscope, count fertilized versus unfertilized eggs in five fields of view, and calculate percent fertilization.
  3. Egg density estimation: students use a volumetric-sample method to estimate total egg count in the spawning vessel, recording the calculation in the lab log and comparing their estimate to the instructor's reference count.
Broodstock animals (species per facility availability), spawning tanks, temperature control unit, sterile seawater, plankton sieves (various mesh sizes), glass petri dishes, stereo microscope, hand-held tally counter, lab log, PPE (gloves, eye protection)Observation checklist completed with all 12 required fields; fertilization rate within ±5 percentage points of instructor reference count; egg density estimate within 20% of instructor count — all three within tolerance to pass.
6Larval Rearing: Tank Setup and Early-Stage Management18labStudents will set up a larval rearing tank to species-appropriate specifications—salinity, temperature, light intensity, and aeration level—and manage first-feeding and daily density assessments for a minimum five-day rearing period.
  1. Tank commissioning checklist: students sterilize a larval tank with an approved disinfectant at posted dilution, rinse with filtered seawater, fill to target volume, adjust all parameters to species specification using the multi-parameter meter, and verify conditions before receiving larvae.
  2. Larval density sampling: each day for five days, students take a 1-liter volumetric sample, count larvae under a stereo microscope, extrapolate to total tank density, record in the production log, and calculate daily percent survival relative to stocking density.
  3. First-feeding observation and record: on the appropriate developmental day, students add live feed at the prescribed density, observe larvae feeding behavior under a light microscope, note gut-fullness score on a standardized scale, and record feed addition in the log.
Fiberglass or polyethylene larval tanks, approved hatchery disinfectant (e.g., sodium hypochlorite at posted concentration), multi-parameter meter, aeration stones, light meter (lux), stereo microscope, compound microscope, volumetric pipettes, plankton counting chambers, production log formsTank commissioning checklist signed off by instructor before larvae are added; five-day density log complete with daily survival calculations within 5% of instructor verification counts; gut-fullness scores recorded on the correct scale — all three required.
7Live Feed Culture: Microalgae Production16labStudents will maintain a continuous microalgae culture of at least one species (e.g., Nannochloropsis, Tetraselmis, or Isochrysis), scale up from a flask to a carboy, and use a hemocytometer or spectrophotometer to estimate cell density against a target harvest density.
  1. Culture transfer and scale-up: following aseptic technique, students transfer a flask culture into a two-liter carboy with f/2 or equivalent medium, set aeration and lighting parameters, label with species, transfer date, and their initials, and record in the live-feed log.
  2. Cell density assessment: students prepare a hemocytometer slide, count cells in five grid squares, calculate cells-per-mL using the hemocytometer formula, and compare to the target harvest density; or use a spectrophotometer and a species-specific OD-to-cell-density calibration curve to estimate density.
  3. Contamination identification exercise: instructor provides three flasks—one clean culture, one with bacterial contamination, one with protist contamination—and students examine each under a microscope, document observations, and recommend corrective action (autoclave and restart, or UV treatment) for the contaminated flasks.
Starter microalgae cultures, f/2 or equivalent liquid medium, 125 mL and 2 L carboys, aeration tubing, cool-white fluorescent or LED grow lights, autoclave or pressure cooker, hemocytometer with cover slips, compound microscope, spectrophotometer (optional), live-feed log, aseptic transfer hood or laminar-flow if availableCulture transfer completed using aseptic technique with no cross-contamination (verified by instructor observation at transfer); cell density estimate within 20% of instructor reference count; contamination identification correct for all three flasks — 100% correct on contamination IDs required.
8Live Feed Culture: Rotifer and Artemia Production16labStudents will culture and enrich rotifers to a target density and hatch and harvest Artemia nauplii at the correct instar stage, confirming quality by density count and gut enrichment color check.
  1. Rotifer batch culture: students inoculate a five-liter vessel with a rotifer starter culture, feed with microalgae at the posted ration, aerate, maintain temperature, and harvest a 500 mL sample every 24 hours over three days, counting rotifers per mL using a volumetric sample and a stereo microscope.
  2. Enrichment protocol: on harvest day, students add a commercial lipid-enrichment product (e.g., algae-based HUFA enrichment) to the rotifer vessel at the manufacturer-stated dose and duration, then verify enrichment by examining rotifers under a microscope for orange-yellow gut coloration.
  3. Artemia hatching and harvest: students hydrate and hatch a measured dose of Artemia cysts in a cone separator under continuous aeration and light, harvest nauplii at 24 hours by draining into a fine-mesh sieve, count nauplii per mL in a subsample, and record hatch efficiency as a percentage of cyst dose.

9Weaning, Nursery Phase, and Feed Transition16demoStudents will execute a structured weaning protocol transitioning larvae from live feed to a commercial microparticulate diet, recording intake, growth, and survival data across a minimum three-step co-feeding schedule.
  1. Co-feeding schedule design: using a species data sheet and the instructor's weaning template, students calculate the daily ration of live feed and dry feed for each step of a five-day weaning protocol, expressing both as percent body weight and as a volume or mass per tank.
  2. Feed delivery and observation: students deliver the day's ration at the prescribed frequency, observe and record feeding behavior (schooling near surface, individual strikes on pellets), note any uneaten feed accumulation, and siphon waste from tank bottoms.
  3. Growth sampling: every other day students anesthetize a subsample of larvae with MS-222 (instructor-supervised) at the posted concentration, measure total length of ten individuals with a calibrated ocular micrometer or digital calipers, record data in the log, and calculate mean daily growth rate (mm/day).
Larvae at weaning stage, commercial microparticulate diet (species-appropriate particle size), MS-222 (tricaine methanesulfonate) and sodium bicarbonate buffer, digital calipers or calibrated ocular micrometer, stereo microscope, siphon hose, weaning schedule templates, production logWeaning schedule calculations correct within 5% of instructor answer key; feeding observations recorded daily with no missing entries; growth rate calculated correctly for each sampling event — 80% of calculations correct across all entries to pass.
10Biosecurity, Disease Recognition, and Hatchery Sanitation18theoryStudents will implement a hatchery biosecurity plan including quarantine procedures for incoming stock, equipment disinfection protocols, and basic gross-pathology examination to distinguish between three common hatchery disease presentations.
  1. Biosecurity plan review and gap analysis: students read a sample hatchery biosecurity plan and a list of ten recent facility events (e.g., new broodstock delivered with no quarantine, shared nets between tanks, visitor entry without boot dip), then identify which events violate the plan and propose corrective procedures in writing.
  2. Equipment disinfection stations: students rotate through three stations—net and basket disinfection with sodium hypochlorite dip, UV-pass of water, and quaternary ammonium spray of hard surfaces—following posted dilution SOPs, measuring concentration with a test strip or titration kit, and documenting in the sanitation log.
  3. Disease recognition case studies: using laminated reference cards with photographs and descriptions of bacterial fin rot, VHS (viral hemorrhagic septicemia), and fungal saprolegniosis, students examine three sets of gross-pathology photographs and written clinical signs, identify the most likely condition for each, and list the immediate isolation and notification steps required.
Sample hatchery biosecurity plan, sodium hypochlorite solution, quaternary ammonium disinfectant, test strips (chlorine) or titration kit, UV lamp (demonstration unit), disease reference cards (USDA APHIS or state aquatic animal health authority source), sanitation log forms, PPE (gloves, eye protection, apron)Gap analysis identifies at least 8 of 10 biosecurity violations correctly; all three disinfection stations completed at correct concentrations verified by test strip or instructor measurement; all three disease case studies correctly identified — 80% overall accuracy required to pass.
11Hatchery Record-Keeping, Production Planning, and Regulatory Awareness16theoryStudents will construct a complete hatchery production record for a simulated 30-day cohort run, apply basic production-planning math to project stocking numbers and feed costs, and identify the categories of permits and regulatory requirements that commonly govern hatchery operations.
  1. Production record reconstruction: using a data set of daily water quality, mortality, feeding, and growth entries with ten deliberate errors, students find and correct all errors, calculate 30-day survival rate and feed conversion ratio (FCR), and summarize results in a one-page cohort report.
  2. Feed cost and stocking projection: given a price list for live feeds and dry pellets, current tank inventory, and a target number of juveniles for sale in 60 days, students calculate total feed cost, space requirements, and the minimum stocking density needed to meet the sales target after applying an estimated survival rate.
  3. Regulatory mapping exercise: using publicly available guidance from NOAA, the U.S. Army Corps of Engineers, and the relevant state fish and wildlife agency, students complete a table identifying which of five common hatchery activities (water intake, effluent discharge, interstate transport of live fish, chemical treatment, use of genetically modified organisms) typically requires a permit and which agency issues it.
Simulated 30-day data set (instructor-prepared), feed price list, cohort report template, spreadsheet software, NOAA aquaculture permit guidance pages, state aquatic invasive species transport regulations (state-specific current document), regulatory mapping tableAll ten data-set errors identified and corrected; FCR and survival rate correct within 5%; feed cost and stocking projection within 5% of instructor answer; regulatory table at least 80% accurate — pass requires 80% total accuracy across all tasks.
12Integrated Hatchery Operations: Full Production Cycle Lab18labStudents will independently manage an assigned hatchery tank system for a minimum 10-day integrated production run, executing all daily tasks—water quality, feeding, sampling, live-feed preparation, and record-keeping—and presenting a final cohort report.
  1. Daily operations rotation: each student independently completes the full morning task list for their assigned tank—water quality sweep, mortality count and removal, feeding, and log entry—within the posted two-hour morning window, without instructor prompting, for ten consecutive weekdays.
  2. Problem response documentation: when any parameter exceeds threshold (as it will, by instructor design at least once), students identify the deviation in their log, list three possible causes, select and implement a corrective action, and record outcome within four hours.
  3. Cohort report presentation: at the end of the run, each student prepares and orally presents a five-minute cohort summary including survival curve, growth data, FCR, notable events, and one recommendation for improving the protocol, to the class and instructor.
Operational hatchery tank assigned per student, full complement of water quality meters and test kits, live-feed cultures, species-appropriate dry feed, production log (blank), siphon equipment, stereo microscope, cohort report template, presentation materialsLog complete for all 10 days with no missing entries; at least one deviation correctly identified, documented, and corrected with outcome recorded; cohort report contains accurate survival rate, growth rate, and FCR with supporting data — all three requirements must be met to pass.

PADI Recreational Dive Planner wheel and eRDPml, recreational dive computers (one per pair), PADI Open Water Diver Manual, dive planning worksheet templatesFive dive-planning problems completed on paper without errors in pressure group or surface interval determination; 100% accuracy required on any problem involving nitrogen loading (retest permitted once).
3Diving Equipment: Scuba Systems — Assembly, Inspection, and Maintenance18demoStudents will assemble, perform a pre-dive BWRAF safety check, and correctly identify three simulated faults on a scuba unit before any in-water use.
  1. Instructor demonstration of cylinder valve inspection, regulator first-stage and second-stage assembly, BCD inflation/deflation systems, and mask/fin/wetsuit selection; students follow along step-by-step with their own unit.
  2. Fault-finding exercise: instructor pre-loads each station's scuba unit with one concealed fault (e.g., O-ring missing, SPG reading zero, low-pressure inflator free-flowing); students rotate stations and document findings on an inspection checklist.
  3. Students practice the PADI BWRAF (BCD, Weights, Releases, Air, Final check) buddy check procedure in pairs until each student completes the full sequence correctly from memory in under three minutes.
Open-circuit scuba units (BCDs, regulators with SPGs, cylinders, masks, fins, wetsuits), equipment inspection checklists, fault-insertion kit, cylinder fill station or pre-filled cylinders, manufacturer service manualsPractical checklist: student identifies all three pre-loaded faults and completes BWRAF check without prompting; any missed safety fault is an automatic recheck before pool entry.
4Surface-Supplied Air (SSA) Equipment and Topside Support Roles16demoStudents will set up an SSA dive station, correctly don and communicate through a band-mask or full-face mask, and describe the duties of the dive supervisor and standby diver per ADCI standards.
  1. Instructor-led setup of a commercial SSA panel: students connect umbilical, verify gas supply pressure, test communications, and check bailout cylinder following an ADCI-format pre-dive checklist.
  2. Role rotation exercise: students take turns as dive supervisor, standby diver, and umbilical tender while a classmate performs a simulated dive (in shallow confined water), using standardized line-pull signals and radio/hardwire communications.
  3. Students draft a written dive plan for a net-pen inspection using SSA, specifying gas supply calculations (volume needed at depth for planned bottom time plus reserve), communication method, and emergency action steps.
SSA panel trainer or operational SSA system, umbilical, band mask and full-face mask (Kirby Morgan or equivalent), bailout cylinder, ADCI Consensus Standards, communication headsets or hard-wire system, pre-dive checklist formsInstructor-observed role performance: student correctly executes topside supervisor role (gas checks, communications, log entries) without critical omissions; competency checklist must have zero safety-critical gaps.
5Confined Water Skills 1 — Buoyancy, Trim, and Basic Underwater Navigation20labStudents will achieve neutral buoyancy within one meter of a target depth and navigate a 30 m rectangular pattern using compass and natural references with less than 3 m error on return.
  1. Buoyancy-weighting exercise in shallow confined water: students add or remove weight until hovering motionless in mid-water for 30 seconds at the end of a dive with a nearly empty cylinder.
  2. Trim and finning drills: instructor demonstrates frog kick, modified flutter kick, and backward kick to avoid silt disturbance; students practice each kick style and receive feedback via hand signals before moving to finning along a transect line.
  3. Compass navigation: students swim a 15 m heading on a reciprocal compass course, then complete a rectangular navigation pattern (four 90° turns) using compass bearings, surfacing within 3 m of the starting point to pass.
Confined water facility (pool, minimum 2 m depth), scuba units, weight systems, underwater compasses, transect lines, measuring tape, underwater slatesSkill performance rubric: neutral buoyancy hover 30 seconds (pass/fail) and rectangular navigation return within 3 m (measured by instructor); both criteria must be met to advance to open-water lessons.
6Confined Water Skills 2 — Emergency Procedures and Air Management18labStudents will correctly perform out-of-air ascent procedures, alternate air source donation, and controlled emergency swimming ascent (CESA) to PADI standards in confined water.
  1. Simulated out-of-air scenario: buddy pairs practice octopus (alternate second stage) donation and two-person controlled ascent, maintaining contact and ascending at approximately 9 m per minute as per PADI standards.
  2. CESA drill: each student performs a controlled emergency swimming ascent from the bottom (maximum 9 m) while continuously exhaling and maintaining a slow, controlled rise without exceeding ascent rate guidelines.
  3. Air management exercise: students are given a starting pressure and a target task; they track air consumption rate (surface air consumption rate calculation) on an underwater slate and must surface with a minimum reserve as specified in the dive plan.
Scuba units with SPGs, octopus regulators, underwater slates, stopwatch, depth gauge or computer, pool with minimum 3 m section, PADI performance standards reference cardInstructor-observed performance: CESA and octopus donation each completed without panicking, surfacing, or breath-holding based on PADI skill performance requirements; retest permitted once per skill with additional coaching.
7PADI Rescue Diver — Recognizing and Managing Dive Emergencies20theoryStudents will identify the behavioral signs of a stressed, tired, panicked, or unresponsive diver and select the correct rescue approach for each scenario, referencing the PADI Rescue Diver manual.
  1. Scenario card exercise: each student draws a diver-emergency card (e.g., 'diver signals OK from surface but is not moving toward boat'), identifies the problem type, selects an initial approach, and defends the choice to a small group.
  2. Video analysis: instructor plays three short clips of diver stress escalation; students annotate observation worksheets identifying early warning signs, moment of panic onset, and missed intervention points.
  3. Group development of a dive emergency response flowchart for an aquaculture worksite, incorporating surface recognition, in-water rescue options, removal from water, oxygen administration, and EMS activation — submitted as a one-page reference card.
PADI Rescue Diver manual (current edition), scenario cards, projector/screen, oxygen unit (for familiarization), emergency response flowchart templateWritten scenario quiz: five emergency scenarios answered with correct problem identification and response sequence; pass mark 80%; maps to PADI Rescue Diver knowledge review standard.
8PADI Rescue Diver — In-Water Rescue Skills Practice22practiceStudents will execute tired-diver tow, panicked-diver approach and control, and submerged unresponsive diver search and surface rescue to PADI Rescue Diver performance standards in confined and open water.
  1. Tired-diver tow drill: in pairs, one student acts as an exhausted diver at the surface; the rescuer approaches from behind, secures the diver, and tows to a designated exit point using a two-minute tow minimum without releasing contact.
  2. Panicked-diver scenario: rescuer approaches from a safe angle, calms a simulated panicking diver (played by classmate using scripted behavior), and assists them to safety while protecting themselves from being submerged by the victim.
  3. Submerged unresponsive diver drill: rescuer locates a weighted mannequin placed at the bottom in a confined water area, brings it to the surface, establishes airway, and initiates two rescue breaths before the pair removes the victim to the pool edge for further care.
Open-circuit scuba units, rescue mannequin (weighted), throw bag, tow line, rescue breathing mask, PADI Rescue Diver manual, confined water pool and adjacent open water if availableInstructor-evaluated skill checklist per PADI Rescue Diver standards: each of the three rescue skills marked satisfactory; unsatisfactory on any critical step (e.g., airway not established, rescuer submerged) requires a full repeat of that skill.
9DCS, Barotrauma, and Hyperbaric Emergency Management14theoryStudents will differentiate decompression sickness Type I and Type II symptoms from arterial gas embolism and describe the correct first-aid protocol and referral pathway for each condition.
  1. Symptom identification matching exercise: students receive a set of patient vignette cards (joint pain, skin mottling, loss of consciousness, visual disturbance, etc.) and sort them into DCS Type I, DCS Type II, and AGE categories, then check against an answer key and discuss borderline cases.
  2. Guest speaker or recorded presentation from a hyperbaric medicine professional (or use DAN recorded materials) covering chamber referral procedures, oxygen first aid, and the DAN emergency hotline process.
  3. Group tabletop exercise: a diver surfaces unresponsive after a deep repetitive dive at a remote aquaculture site; students work through the emergency action sequence — oxygen, positioning, EMS call, documentation — using the scenario to complete a DAN Accident Report form template.
DAN Diving Accident Management Flowchart, symptom vignette cards, DAN oxygen first-aid provider guide, DAN Accident Report form template, oxygen unit (demand valve and non-rebreather mask), projectorWritten quiz: ten symptom-identification and action-sequence questions; pass mark 80%; maps to ADCI safety and emergency management knowledge area.
10Underwater Work Tasks for Aquaculture and Marine Science20fieldStudents will complete a simulated net-pen inspection transect, collect a biological specimen into a sample bag, and use an underwater slate to record data to a specified protocol without surfacing prematurely.
  1. Net inspection simulation: students swim along a suspended mesh panel in the pool or open-water site, using a systematic top-to-bottom, left-to-right search pattern, marking simulated damage locations on an underwater slate using a standardized code.
  2. Specimen collection drill: students locate and bag three tagged objects (representing invertebrate specimens) placed at various depths, labeling each bag with collection depth and compass bearing recorded on slate before surfacing.
  3. Transect survey practice: students lay a 10 m measuring tape along the bottom and record all 'organisms' (tagged objects placed by instructor) within 1 m on each side, counting and categorizing them; data is transferred to a topside data sheet immediately after surfacing.
Scuba units, underwater slates and pencils, mesh panel or net section, sample collection bags, measuring tape, numbered identification tags (simulated specimens), topside data recording sheetsInstructor-reviewed underwater slate and topside data sheet: data completeness at 90% or above (all items within transect recorded); any premature unplanned surfacing during task results in task repeat.
11Dive Logging, Record-Keeping, and ADCI Documentation Standards18practiceStudents will complete a full ADCI-format dive record package — pre-dive plan, dive log, equipment inspection record, and post-dive incident report — for a simulated commercial dive operation.
  1. Review of ADCI Consensus Standards record-keeping requirements; students annotate a blank ADCI dive record form identifying each mandatory field and the consequence (regulatory violation) of leaving it incomplete.
  2. Simulated dive day: using data from a preceding pool session, each student completes a pre-dive plan, dive log (depth, bottom time, gas used, tasks completed), and equipment inspection record as if preparing an ADCI-compliant file.
  3. Peer review exercise: students exchange completed packages and audit each other's documentation using an ADCI compliance checklist, flagging missing fields or inconsistencies and providing written feedback before instructor final review.
ADCI Consensus Standards (current edition), ADCI dive record forms, PADI dive log books, equipment inspection checklists, peer audit checklist, pensInstructor-graded documentation package: all mandatory ADCI fields complete and internally consistent; pass mark 90% of required fields correctly populated; maps directly to ADCI written-record requirement.
12Integrated Open-Water Dive Assessment and Commercial Dive Simulation8fieldStudents will execute a complete commercial-style dive evolution — pre-dive documentation, in-water work tasks, emergency response scenario, and post-dive debriefing — demonstrating competency across all course skill areas.
  1. Students rotate through three roles (diver, standby diver, dive supervisor) during a two-tank open-water session; each role is evaluated against an ADCI role-performance checklist for a minimum of one full dive evolution per role.
  2. Mid-dive emergency injection: instructor signals a simulated diver distress at the surface; standby diver and supervisor must execute the emergency response sequence from Lesson 8 while the logging student documents the incident on an accident report form.
  3. Post-dive debrief: each student completes a self-evaluation rubric rating their own buoyancy, task completion, communication, and documentation quality, then compares it against instructor ratings during a structured 20-minute debrief.
Scuba units, SSA panel (if available), ADCI role-performance checklists, underwater slates, rescue mannequin, oxygen unit, post-dive debrief rubrics, dive logsAll three role checklists rated satisfactory by instructor (no critical safety omissions); self-evaluation debrief submitted; this session serves as the terminal practical competency gate for the course.

#LessonHrTypeObjectiveActivitiesMaterialsCheck
1Project Design and Safety Planning48theoryStudents produce a complete written project proposal—including a SMART-objective problem statement, site risk assessment, PPE and dive safety plan, materials list, and data-collection methodology—that is approved by the instructor before any fieldwork begins.
  1. Students analyze three sample industry project reports (hatchery improvement study, reef transect survey, shellfish density assessment) using an annotated reading guide to identify how each section maps to a professional deliverable, then list the elements they must replicate.
  2. Each student drafts a one-page problem statement and methodology outline for their chosen project topic, receives structured peer critique using a provided rubric, and revises until the instructor signs off on scope and feasibility.
  3. Students complete a site-specific Job Hazard Analysis (JHA) form—identifying physical, chemical, biological, and diving hazards—and pair it with a written PPE selection rationale and emergency action plan, presenting both to the class for group critique before submitting for instructor approval.
Sample industry technical reports, SMART-objectives reference card, OSHA Job Hazard Analysis blank form, ADCI surface-supply and scuba safety checklists, PADI dive planning tables, program style guide for technical writing, project proposal template, peer-review rubricInstructor approves the written proposal only when all of the following are present and correct: SMART objectives, site risk assessment with controls for every identified hazard, an approved dive plan or documented rationale for no diving, a methodology that references at least three program content areas, and a realistic materials and timeline list. Approval = pass; proposals not meeting all criteria are returned for revision within one week.
2Fieldwork Execution and Data Collection72fieldStudents carry out their approved project in the field or facility setting, collecting all planned data using calibrated instruments and standard protocols while maintaining a compliant daily logbook and operating under continuous instructor or designee safety supervision with zero recorded safety violations.
  1. At the start of each fieldwork session, students conduct and document a pre-dive or pre-entry safety check (equipment inspection, buddy/supervisor confirmation, site hazard reassessment) using the program safety checklist; any deficiency must be corrected before work proceeds, and the checklist is signed by the supervising instructor.
  2. Students collect biological and water quality data—dissolved oxygen, temperature, salinity, pH, turbidity, and biological counts or transect measurements as appropriate to their project—using multiparameter meters, refractometers, Secchi disks, or transect tapes, and enter all raw readings into a formatted, date-signed field data sheet the same day they are collected.
  3. At the close of each session, students photograph key observations, calibrate or rinse and store instruments per manufacturer protocol, and write a minimum 150-word field journal entry summarizing what was observed, what deviated from the plan, and what will be adjusted next session; the instructor initials each entry.
Multiparameter water quality meter (YSI or equivalent), refractometer, Secchi disk, pH meter and buffer solutions, dissolved-oxygen meter, field transect tapes and quadrats, waders or exposure suits as site requires, full PPE per approved JHA, PADI/ADCI dive equipment where applicable, pre-printed field data sheets, bound waterproof field logbook, digital camera or smartphone in protective housing, instrument calibration logsInstructor evaluates logbook and data sheets weekly against a 10-point field-log rubric: entries present for every session, raw data legible and signed, calibration records complete, field journal narrative present, safety checklist signed. Score of 8/10 or higher each week = satisfactory progress. Any week below 8/10 triggers a corrective conference; two consecutive unsatisfactory weeks require an instructor-approved remediation plan. Zero safety violations is a non-negotiable threshold—any uncontrolled safety breach stops fieldwork pending review.
3Data Analysis, Report Writing, and Portfolio Assembly60practiceStudents analyze their collected data using appropriate descriptive statistics and graphing, write a complete technical report following the program style guide, and assemble a final project portfolio containing all documentation produced from proposal through fieldwork.
  1. Students enter all raw field data into a spreadsheet (Microsoft Excel or Google Sheets), calculate descriptive statistics (mean, range, and where appropriate, percent change or simple trend analysis), and produce at least two publication-quality figures (labeled axes, units, captions) that directly answer their project objectives; the instructor reviews a draft figure set before students proceed to writing.
  2. Students write each section of the technical report in sequence—abstract, introduction, methods, results, discussion, conclusions, references—using the program style guide and an industry report checklist; each section is submitted as a draft, returned with instructor comments within 48 hours, and revised before the next section is begun, ensuring iterative improvement rather than a single last-minute submission.
  3. Students organize their complete project portfolio in a professional binder or digital folder with a table of contents, including: approved proposal, all signed field data sheets, calibration logs, logbook (photocopied or printed), figure drafts, PPE and safety documentation, any dive records, and the final technical report; they conduct a self-audit against the portfolio checklist and certify completeness before submission.
Laptop with spreadsheet software and word processor, program style guide, industry technical report checklist, portfolio assembly checklist, graph paper as backup, scientific calculator, reference materials from courses 2–6 (water quality standards, hatchery SOP references, reef transect protocol guides), APA or industry citation guide as specified by programTechnical report is scored on a 100-point rubric: completeness of all required sections (30 pts), accuracy and clarity of data presentation (25 pts), logical discussion tied to results (20 pts), correct citations and professional formatting (15 pts), grammar and clarity (10 pts). Passing score is 75/100. Portfolio completeness is assessed as pass/fail against the checklist—all 10 required document categories must be present to pass. Students below 75 on the report have one opportunity to revise within one week.
4Oral Defense and Professional Presentation36demoStudents deliver a structured 15-minute oral presentation of their project followed by a minimum 10-minute panel question period, demonstrating accurate technical knowledge, professional communication, and the ability to respond to critical questions about methods, results, and real-world applications.
  1. Students prepare and rehearse a presentation using slides or poster format that covers: project rationale, objectives, site and safety plan, methods, results with figures, discussion of findings relative to industry practice, and two or more specific recommendations for an aquaculture facility or restoration program; a peer practice defense is held before the formal panel, with peers scoring each other using the defense rubric so presenters receive actionable feedback.
  2. Each student presents before a panel of at least two instructors and, where possible, one external industry evaluator (aquaculture farm operator, hatchery manager, or reef restoration project lead); the panel scores content accuracy, clarity of data explanation, and professional demeanor using the 50-point defense rubric during the live presentation.
  3. After the scored presentation, the panel conducts a minimum 10-minute technical question session drawing from any area of the student's project and from the broader program content—including water quality interpretation, species husbandry decisions, dive safety rationale, or restoration ecology—and scores the quality and accuracy of responses on the remaining 50 points of the rubric.
Projector or display screen, laptop, presentation slides or printed poster, pointer, defense rubric (printed copies for each panelist), peer practice rubric, student technical report and portfolio available to panel during defense, timerDefense is scored on a 100-point rubric split equally between presentation (50 pts: content accuracy 20, data explanation 15, clarity and organization 10, professional demeanor 5) and Q&A (50 pts: accuracy of responses 30, depth of reasoning 15, acknowledgment of uncertainty without fabrication 5). Passing score is 75/100 overall with no section score below 30/50. Students scoring below 75 overall or below 30 in either section are offered one re-defense opportunity within two weeks using revised materials.

#LessonHrTypeObjectiveActivitiesMaterialsCheck
1Diagnostic Assessment & PADI Open Water Knowledge Domain Review20theoryLearners identify personal knowledge gaps across all PADI Open Water Diver knowledge review sections and achieve a passing practice score on each section after targeted review.
  1. Complete a timed, full-section PADI Open Water knowledge review diagnostic test covering equipment, dive planning, underwater environment, physics, physiology, and problem management; score and self-analyze results by domain.
  2. Work in small groups through PADI instructor-led content review sessions on the two lowest-scoring domains per student, using PADI Open Water Diver Manual tables, charts, and RDP/eRDPML exercises to reinforce dive table reading and no-decompression limit planning.
  3. Complete a second timed practice test for each knowledge review section and record scores on a personal tracking sheet, setting a target of meeting or exceeding the PADI minimum passing threshold before mock exam day.
PADI Open Water Diver Manual (current edition), PADI Recreational Dive Planner (RDP table and eRDPML), PADI Knowledge Review answer sheets, dive physics formula reference card, whiteboard, calculatorEach learner scores at or above the PADI minimum passing percentage on every individual knowledge review section practice test; instructor reviews any section below that threshold with the student before the course advances.
2PADI Rescue Diver Theory & Practical Skills Review22labLearners accurately recall all PADI Rescue Diver knowledge review content and execute each required confined- and open-water rescue skill to the standard required for a PADI certification checkout.
  1. Review all PADI Rescue Diver knowledge review chapters—self-rescue, recognizing and managing stress in divers, emergency management and equipment, rescuing panicked and unresponsive divers, and post-rescue care—through written practice questions and case-study discussion, targeting the PADI minimum passing percentage on every section.
  2. In the pool, practice and self-evaluate each PADI Rescue Diver confined-water exercise: tired-diver tow, panicked-diver approach and control, equipment removal in water, in-water rescue breathing while towing, and unresponsive-diver-at-surface management including mask removal and ventilation.
  3. Conduct a timed, full open-water rescue scenario—missing diver search pattern, locate and surface an unresponsive diver, tow to exit, transition to CPR with AED use—with a classmate acting as victim and instructor evaluating against the PADI Rescue Diver performance requirements checklist.

3ADCI Commercial Diver Written Exam Domain Review26theoryLearners correctly solve practice items in every ADCI written examination content area—dive physics, physiology, decompression theory, surface-supplied equipment, underwater work methods, ADCI/OSHA regulatory requirements, and emergency procedures—at a level consistent with passing the official exam.
  1. Complete a timed diagnostic practice test structured around the ADCI Commercial Diver consensus standards content areas; score by domain and rank areas for priority review, then work through instructor-led sessions on the lowest-scoring areas using the ADCI Consensus Standards for Commercial Diver Training document, US Navy Diving Manual (current revision) excerpts, and applicable OSHA commercial diving regulations (29 CFR Part 1910, Subpart T) as reference.
  2. Drill applied calculation problems in small groups: absolute/gauge pressure conversions, gas volume changes at depth using Boyle's Law, equivalent air depth for nitrox, decompression stop planning using dive tables, and partial pressure calculations using Dalton's Law—matching the style and difficulty of ADCI exam items.
  3. Participate in a facilitated question-and-answer review of ADCI regulatory content (diving team qualifications, standby diver requirements, equipment inspection logs, accident reporting) and emergency procedures (omitted decompression management, suspected DCS recognition and surface O₂ first aid, unconscious diver emergency), using scenario prompts to apply regulatory knowledge to realistic commercial dive job situations.

4Full Mock Certification Examinations & Individualized Remediation22practiceLearners complete two timed, full-length mock exams simulating actual PADI and ADCI credentialing exam conditions and achieve passing scores, demonstrating readiness to sit official certification examinations.
  1. Sit Mock Exam 1: a timed, closed-book written examination combining PADI Open Water and Rescue Diver knowledge review content and an ADCI-style commercial diver written exam; materials are collected, exams are scored immediately, and each learner receives a domain-by-domain score report identifying any area below the credential passing threshold.
  2. Participate in a structured remediation session: learners below passing on any domain attend an instructor-led targeted review using worked examples, while learners who passed all domains serve as peer tutors and review edge-case scenarios; all learners complete focused practice drills on their two lowest-scoring domains.
  3. Sit Mock Exam 2 under full exam conditions (timed, individual, no notes); upon completion, review answers item by item as a group, discuss common error patterns, and complete a brief practical rescue skills run-through in the pool to confirm readiness; each learner completes a written exam-day readiness checklist and personal action plan for any remaining weak areas.
Instructor-developed full-length mock exams (PADI knowledge review format and ADCI written exam format), answer sheets, timer, pool access, scuba units, rescue equipment, CPR mannequin, training AED, PADI and ADCI score rubrics, exam-day readiness checklist templateLearner achieves a passing score on both Mock Exam 1 and Mock Exam 2 across all credential domains; practical rescue skills run-through completed with zero critical failures; any learner not meeting the passing standard on Mock Exam 2 receives a documented remediation plan and completes an additional instructor-administered practice session before the official exam date.
