5.16 - Aquaculture

Question 1

Aquacultural Benefits

Answer 1

• Raising fish, or other aquatic species in cages/enclosures underwater

Benefits:
- Requires only small amount of water, space, and fuel
- Reduces risk of Fishery collapse (90% population decline in a fishery)
- Doesn’t take up any land space (compared to beef, pork, chicken)

Question 2

Aquaculture Drawbacks

Answer 2

• High density produces high concentration of waste (e. coli & eutrophication risks)
• High density increases disease risk, which can be transmitted to wild populations as well
• May introduce non-native species or GMOs to local ecosystem if captive fish escape
• Fish are fed antibiotics which can contaminate water via their waste
