Tilapia production in Brazil increased 3 - 4 percent in 2022. Philippines: 267,735 In the Philippines, several species of tilapia have been introduced into local waterways and are farmed for food. Tilapia fish pens are a common sight in almost all the major rivers and lakes in the country, including Laguna de Bay, Taal Lake, and Lake Buhi.
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]

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.

Sturgeon grown at high density in a partial recirculating aquaculture system. Reduced water requirements as compared to raceway or pond aquaculture systems. [16] Reduced land needs due to the high stocking density [17] Site selection flexibility and independence from a large, clean water source. [18] Reduction in wastewater effluent volume. [19]
Optimal stocking density is often defined by the carrying capacity of the stocked environment and the amount of individual space needed by the fish, which is very species specific. Although behavioural interactions such as shoaling may mean that high stocking densities are beneficial to some species, [ 113 ] [ 117 ] in many cultured species ...
The high density of fish in these mesh tanks is very tempting for predators of the sea and air (19). To protect the harvest from predators protective netting is set up at a high cost. Often times predatorial fish and mammals like seals, sharks, and tuna get caught in these barrier nets and die.
The Nile tilapia (Oreochromis niloticus) is a species of tilapia, a cichlid fish native to parts of Africa and the Levant, particularly Israel and Lebanon. [2] Numerous introduced populations exist outside its natural range.
