Pterygoplichthys disjunctivus, [1] commonly known as the vermiculated sailfin catfish, [2] is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Madeira River basin in Bolivia and Brazil, although it has subsequently been introduced to various countries.
The Top 10 is based on tonnage of fish sold. According to the NFI, this mild-flavored white-fleshed fish is farmed in Asia, and is being used increasingly in food service. It is finding its way onto restaurant menus and into stores, as well, where one may see it called basa, tra, or swai. They are either called Panga, Pangas or Pangasius.
Pterygoplichthys has undergone much shifting in the past decades. Previously Liposarcus, Glyptoperichthys and Pterygoplichthys had been named as separate genera. [2] [3] Since then, these genera were recognized as synonyms of Pterygoplichthys by Armbruster, as the few differences between the genera were not deemed great enough to validate Glyptoperichthys and Liposarcus, and that recognizing ...
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.

Basa (Pangasius bocourti), as it is commonly referred to, is a species of primarily freshwater-dwelling catfish in the shark-catfish family, Pangasiidae, native to the Mekong and Chao Phraya river basins of Mainland Southeast Asia. [2] Economically, these fish are important as a regional food source, and are also prized on the international market.
The walking catfish directly outcompetes the native broadhead catfish. Sailfin molly have harmed native insect populations. The Pterygoplichthys disjunctivus janitor fish has become established in Agusan Marsh. [30]: 14–15 Tilapia may have introduced the Arctodiaptomus dorsalis copepod, which competes with native copepods. [30]: 16
In the stomach, food is further digested and, in many fish, processed in finger-shaped pouches called pyloric caeca, which secrete digestive enzymes and absorb nutrients. Organs such as the liver and pancreas add enzymes and various chemicals as the food moves through the digestive tract. The intestine completes the process of digestion and ...
A small number of productive species including carp, salmon, [108] tilapia and catfish are farmed commercially, producing millions of tons of protein-rich food per year. The UN's Food and Agriculture Organization expects production to increase sharply so that by 2030, perhaps sixty-two percent of food fish will be farmed. [109]
