Fisheries Technologist study plan

Map the Fisheries Technology domain into a one-page concept outline covering gear selectivity, fishing methods, vessel and gear materials, and technology adoption drivers.

Define and contrast the core gear classifications (active vs passive, towed vs static) with two real examples each, writing definitions in your own words.

Explain how mesh size, twine diameter, and hanging ratio interact to determine selectivity, and solve three worked numerical examples on selection curves.

List the main electronic and acoustic technologies used on fishing vessels (echosounder, sonar, GPS plotter, AIS, VMS) and state the operational purpose of each.

Describe bycatch reduction devices and turtle excluder devices by mechanism, and justify when each is appropriate.

Compare fishing gear performance indicators (catch per unit effort, fuel per tonne landed, discard rate) and compute each from a small sample dataset.

Summarize the legal and certification frameworks that shape gear choice (gear marking, logbook reporting, eco-labelling), without relying on any single national code.

Identify five emerging technologies (e.g. LED lights, smart hooks, machine-vision sorting) and state one advantage and one limitation for each.

Diagram the water-quality envelope for a cultured species of your choice, listing safe ranges for dissolved oxygen, ammonia, nitrite, pH, temperature, and salinity.

Calculate stocking density, feeding rate as a percentage of biomass, and expected feed conversion ratio for a pond or tank scenario.

Explain the nitrogen cycle in a recirculating aquaculture system and identify where biofiltration, solids removal, and aeration sit in the flow.

Compare pond, cage, raceway, and RAS production systems on capital cost, control, and biosecurity risk in a short written comparison.

Outline the reproductive cycle of a cultured finfish or shrimp and describe induced spawning, egg incubation, and larval rearing steps in sequence.

Explain broodstock selection, genetic improvement basics, and the risks of inbreeding in hatchery populations.

List the major notifiable aquatic animal diseases and state the biosecurity measure that interrupts each transmission route.

Describe how aquafeed is formulated (protein, lipid, carbohydrate, vitamin and mineral premix) and explain fishmeal and fish oil substitution options.

Classify the main commercial fishing methods (trawl, purse seine, gillnet, longline, trap, dredge) by target species, habitat, and selectivity profile.

Explain stock assessment concepts: recruitment, natural and fishing mortality, biomass reference points, and maximum sustainable yield, using a simple surplus-production model.

Interpret a length-frequency distribution and state what it suggests about growth overfishing.

Describe the purpose and limitations of harvest control rules and total allowable catch setting.

Explain the role of vessel monitoring systems, observers, port state measures, and catch documentation schemes in combating illegal, unreported, and unregulated fishing.

Compare input controls (effort limits, closed areas, closed seasons) with output controls (quota, individual transferable quota) and state when each is preferred.

Describe the ecosystem approach to fisheries, including habitat impact of bottom-contact gear and mitigation measures.

Summarize the main international instruments governing fisheries management and flag-state responsibilities at a conceptual level.

Trace the post-harvest chain from landing to retail and identify the critical control points where quality loss or contamination can occur.

Explain rigor mortis, autolysis, and bacterial spoilage in fish and state how chilling rate and temperature control each stage.

Compare preservation methods (ice, chilled seawater, freezing, drying, salting, smoking, canning) on shelf life, quality retention, and cost.

Apply HACCP principles to a fish-processing step, drafting hazard analysis, critical limits, monitoring, and corrective actions.

Calculate yield and weight loss through filleting, freezing, and thawing from given input weights.

Explain fisheries co-management, rights-based allocation, and the role of fisher organisations in resource governance.

Describe quality-grading standards, traceability systems, and cold-chain verification for exported fishery products.

Revisit Domain 1 weak points identified in weeks 1-2 and re-solve every previously missed question without notes.

Complete two timed mixed-domain mock exams and record score, pacing, and error category for each.
