Question

Quizplus · Accepted Answer

Aquaculture is the least expensive means of producing animal protein compared to raising cattle, sheep, or pigs. It takes 1.7-2.2 kg of feed to produce 1 kg of live weight in cattle, 3.5-5.0 kg for sheep, 2.5-3.5 kg for pigs, and only 1.3-1.6 kg for fish in aquaculture. Additionally, fish convert feed more efficiently into protein, require less land and water resources, and produce fewer greenhouse gas emissions compared to traditional livestock production.
