Question
Define “sustainable fishing” in one sentence.
Answer
Sustainable fishing means harvesting fish at or below the regeneration rate so populations can be maintained long term (often linked to MSY).
💡 Hint
Harvest ≤ regeneration.
Question
What is the core idea of sustainability for aquatic food production?
Answer
Harvest must be less than or equal to regeneration so natural capital is maintained.
💡 Hint
Use ≤ renew.
Question
Name three management strategies for capture fisheries.
Answer
Fishing quotas, marine protected areas (no-take zones), and closed seasons (also gear restrictions and certification).
💡 Hint
Quotas + MPAs + closed seasons.
Question
Give two capture fisheries strategies and one aquaculture strategy.
Answer
Fisheries: quotas and MPAs (or closed seasons). Aquaculture: farm herbivorous species or use recirculating systems.
💡 Hint
2 + 1 split.
Question
How do marine protected areas (MPAs) support sustainability?
Answer
They restrict fishing in certain areas so populations can reproduce and recover, helping replenish surrounding fisheries via spillover.
💡 Hint
Safe zones for breeding.
Question
Why must management be “science-based and enforced”?
Answer
Because quotas and rules only work if based on stock data and if illegal overfishing is prevented through monitoring and penalties.
💡 Hint
Rules need enforcement.
Question
What is the key idea linking MSY to sustainability?
Answer
MSY is the maximum catch that can be taken long term without causing population decline; catching above it is unsustainable.
💡 Hint
MSY sets a limit.
Question
Name two sustainable aquaculture practices.
Answer
Farming herbivorous species and using recirculating systems/filters reduce impacts (also IMTA and reduced antibiotic use).
💡 Hint
Lower trophic + better systems.
Question
What is the “MSC label” used for?
Answer
The MSC label is a consumer certification that helps identify seafood from more sustainably managed fisheries.
💡 Hint
Sustainable seafood tag.
Question
Exam tip: best layout for a longer response on sustainable aquatic food production?
Answer
Define sustainability and MSY, then give distinct strategies for capture fisheries and aquaculture, each with a brief “how it helps” explanation.
💡 Hint
Define → strategies → explain.
