Colossoma brachypomum native to South America, the Amazon, is tropical and subtropical food and watch one of the large-scale economic fish. Fast growth, strong resistance to disease, wide diet, hypoxia resistance, delicious meat, is a high economic value of farmed fish, welcomed by the vast number of consumers and farmers.

Freshwater pomfret is more commonly cultivated in the South, not in the North
