Aquaculture Practice Test

Aquaculture can reduce fishing pressure on wild stocks by providing alternative supply, but only if it avoids high reliance on wild fish-based feeds.

Aquaculture eliminates habitat impacts because all farms operate in closed tanks, so coastal ecosystems never experience nutrient enrichment or disease.

Aquaculture always increases biodiversity because farms introduce many non-native species that create new ecological niches and stabilize ecosystems.

Aquaculture guarantees lower greenhouse gas emissions than wild capture because boats are unnecessary, regardless of energy use, feed production, or transport.
