A few species of Oreochromis tilapia, popular known as 'chambo', are the most popular fish in Malawi. [16] They are endemic to bodies of water in Malawi like Lake Malawi, Lake Malombe and the Shire River. [17] Due to over fishing, the fish however is now on the threatened species list. [17] Malawi has fish farms that are dedicated to farming ...
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
Tilapia (/ t ɪ ˈ l ɑː p i ə / tih-LAH-pee-ə) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini.

Freshwater fish ponds were likely first used sometime in the early 20th century, although there is history of small-scale rice-fish system use. Despite many species being introduced for farming, production remained limited due to competition with cropland and a cultural preference for marine fish. Oyster farming began in 1931. [11]
This table includes mainly food fish species, but also listed are crustaceans (crabs and shrimps), cephalopods (squids and cuttlefishs), bivalves, and a reptile (softshell turtle). Note that Oreochromis niloticus and Penaeus monodon appear twice, because substantial amounts are harvested from the wild as well as being extensively raised through ...
Worldwide, the most important fish species used in fish farming are, in order, carp, salmon, tilapia, and catfish. [ 28 ] In the Mediterranean, young bluefin tuna are netted at sea and towed slowly towards the shore.
For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3. The total volume required for a raceway is calculated by dividing the total amount of fish in kg by the desired stocking rate in kg per m 3. [17]
