Commercially grown tilapia are almost exclusively male. Being prolific breeders, female tilapia in the ponds or tanks will result in large populations of small fish. Whole tilapia can be processed into skinless, boneless (PBO) fillets: the yield is from 30% to 37%, depending on fillet size and final trim. [8]
These fish-farming ponds were created as a cooperative project in a rural village in the Congo. These use irrigation ditches or farm ponds to raise fish. The basic requirement is to have a ditch or pond that retains water, possibly with an above-ground irrigation system (many irrigation systems use buried pipes with headers). [31]
Tilapia, carp, and catfish are usually farmed in freshwater. Tilapia is farmed in both ponds and cages. Shrimp and crab farming usually takes place in brackish water. Saltwater farms (mariculture) are used to farm seaweed, as well as green mussels. Some fish, such as groupers and rabbitfish, are farmed in both brackish and salt water.
For example, trout and juvenile salmon are less tolerant of degraded water quality and require a more rapid water turnover than catfish or tilapia. [18] The flow rate necessary to maintain water quality can also change through the year, as the temperature changes and the cultured species grow larger.
It involves raising fish commercially in tanks, fish ponds, or ocean enclosures, usually for food. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery .
Commonly farmed non-salmonid fish groups include tilapia, catfish, black sea bass and bream. In 2007, the aquaculture of salmonids was worth USD $10.7 billion globally. Salmonid aquaculture production grew over ten-fold during the 25 years from 1982 to 2007. In 2012, the leading producers of salmonids were Norway, Chile, Scotland and Canada. [5]

Some species that are commonly raised in hatcheries include Pacific oysters, shrimp, Indian prawns, salmon, tilapia and scallops. The value of global aquaculture farming is estimated to be US$98.4 billion in 2008 with China significantly dominating the market; [ citation needed ] however, the value of aquaculture hatchery and nursery production ...
