Document Summary
Definition: rearing of aquatic organisms under controlled or semi-controlled conditions (un, fao) Animal aquaculture vs. wild caught (fishing: 1970: 6. 3% of fish/shellfish consumed, today: >50% Worldwide, it is the most growing sector of the food animal market exceeding global beef production. It serves as an important stimulus to local and national economies globally; and as of. 2015, >2b people were dependent on aquaculture for food security. Best feed conversion rate: cold-blooded insects and fish convert feed to bod mass more efficiently than birds and mammals do, fish don"t expend energy moving because they are neutrally buoyant (because of swim bladder) Fish are a great source of essential nutrients: high in essential amino acids, high in essential fatty acids (omega-3, omega-6) Nets/cages for fish (oceans, seas, rivers, lochs: can be problematic if bred fish escape. Ropes/strings for bivalves (clams, oysters, mussels, scallops) (see slide) Fish excrete their metabolic wastes into the aquatic environment in which they live.
