Both Chengdu supermarket and Qingshiqiao aquatic products market sell them. Tilapia is the main aquaculture species in China. Its meat is delicious, less prickly and high in protein. It is rich in eight essential amino acids needed by human body, especially glutamic acid and glycine.

Tilapia is deeply loved by people because of its delicious meat, tender meat, no thorns, rich in protein and unsaturated fatty acids. Known as "white meat salmon" and "2 1 fish of the century", it has become one of the hot spots in aquaculture, processing and export in recent years.

At present, tilapia farming is mainly concentrated in Guangdong and Guangxi. In areas with high temperature, such as Hainan, intensive pond cultivation is the main method. In addition to domestic sales, some enterprises also export tilapia as fillets and steaks abroad, which is an excellent breeding variety.

Some kinds of tilapia will hatch with their mouths, that is, females will hold fertilized eggs in their mouths until they hatch into young fish, which is very beneficial to their reproduction. Before some species of tilapia breed, the male fish will dig up the subsoil and build a pot-shaped nest, which has a strong territorial nature. The female fish will lay eggs in the nest, and after hatching, the female fish will put the young fish in her mouth for protection.
