Question
Define aquaculture.
Answer
Aquaculture is the farming of aquatic organisms such as fish, shellfish, and seaweed in controlled environments.
💡 Hint
Fish farming.
Question
Aquaculture: what is it in one phrase?
Answer
Fish farming (farming aquatic organisms).
💡 Hint
Farmed seafood.
Question
Give two advantages of aquaculture.
Answer
It can reduce pressure on wild fish stocks and provide a reliable year-round supply of protein (also creates jobs).
💡 Hint
Less wild catch + steady supply.
Question
Name one pro and one con of aquaculture.
Answer
Pro: reduces pressure on wild stocks. Con: can pollute water or spread disease if poorly managed.
💡 Hint
Balanced view.
Question
Give three disadvantages of aquaculture.
Answer
Common disadvantages include water pollution from waste/chemicals, disease spread in crowded pens, and escapees that compete or breed with wild populations (also feed issues and habitat loss).
💡 Hint
Pollution + disease + escapees.
Question
Why are salmon farms often criticised in sustainability discussions?
Answer
Salmon are carnivorous and often require fish meal/oil from wild fish, increasing pressure on capture fisheries.
💡 Hint
Feed dependency.
Question
Give one example of habitat destruction linked to aquaculture.
Answer
Mangrove forests can be cleared to create shrimp farms, reducing coastal protection and biodiversity.
💡 Hint
Mangroves → shrimp farms.
Question
Why are herbivorous farmed fish often more sustainable than carnivorous fish?
Answer
Herbivorous/omnivorous species (like tilapia/carp) need less fish meal/oil, so they put less pressure on wild fish used as feed.
💡 Hint
Lower on food chain.
Question
Why is aquaculture “not automatically sustainable”?
Answer
Without good management it can cause pollution, disease, genetic impacts on wild stocks, and habitat damage, so sustainability depends on practices used.
💡 Hint
Depends on management.
Question
What is the key sustainability “shortcut” for aquaculture species choice?
Answer
Farming lower-trophic-level species is usually more sustainable.
💡 Hint
Lower is better.
