Document Summary
The farming of aquatic organisms, including fish, molluscs, crustaceans and aquatic plants. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc Farming also implies individual or corporate ownership of the stock being cultivated. About half of global fish and seafood production. (*2014 50%) Freshwater (e. g. lakes, ponds, open bodies of water). Over 500 species were farmed in 2012, but now we focus on about 20 species because they are best-suited to cultivation/propagation in controlled conditions. East coast: #1) mussels; #2) atlantic salmon; #3) oysters. *even though there"s a lot of money and research in farming cod and lobster on the east coast, we haven"t figured out how to best farm them* #1) cage farming/grow-out cages 80% of on aquaculture northern on (colder water holds more oxygen which salmonids, like trout, prefer) Ex: eastern island, eagle rock, fisher harbour (all cold-water fisheries up north)
