There are different species of fishes. All these are found in different regions of the world. The Basa fish is a Pangasius bocourti, which is a category of catfish in the family unit of Pangasiidae. Basa were the inhabitant of the Mekong River Delta in Vietnam and Chao Phraya sink in Thailand. These Basa fish is a chief food fish with an oversea market. They are time and again branded in North America and Australia as "Basa fish" or "bocourti". In the parts of UK, the genus is identified largely as "river cobbler”, with "Basa" also being used on events. In Europe, these Basa fish are frequently advertised as "Pangasius" or "panga". Further correlated shark catfish may sporadically be incorrectly tagged as Basa fish, together with Pangasius hypophthalmus which is a type of iridescent shark and Pangasius which is a yellow tail catfish. The body of a Basa fish is plump and weighty. The smoothed head is wider then it is elongated, with the blunted muzzle having a white mob on its silence. These Basa fish nourish on plants. They produce at the commencement of flood season and the juvenile are primarily seen in June, averaging about 5 cm by the mid of June.
In the year 2002, the United States laid blame on Vietnam of discarding catfish, specifically Pangasius bocourti and Pangasius hypophthalmus, in the markets of America, accusing the importers of Vietnam, who are financially supported by Vietnam's government, of inequitable rivalry. With demands from the U.S. catfish production, the United States assembly approved a law in 2003 putting a stop to the imported fish from being tagged as catfish, besides to outstanding supplementary excises on the imported fish. Under the United State, Food and Drug Administration judgment, only genus from the kin Ictaluridae can be sold as factual catfish. Therefore, currently the Vietnamese exporter of fish, labels their foodstuffs which are sold in the United States as Basa fish. At the height of the "catfish war", U.S. catfish farmers and others were describing the imported catfish as an inferior product.
Well, another fish from the shark family unit is Pangasius. They are the species of catfishes of the shark catfish family. These species are identified by various names. In the year 1993, Pangasius was one of two in existence of genus in the ancestral unit of Pangasiidae. At this point, it was ripping into four subgenera. Pangasius incorporated P. gigas and P. hypophthalmus and was analyzed by the nonappearance of mandibular barbells, the deficiency of teeth in adults and the existence of a single-lobed swim bladder. Pangasius integrated P. micronema and P. pleurotaenia and was spotted by four lobes in the swim bladder and with numerous sections in the last lobe. Pangasius integrated P. humeralis, P. nieuwenhuisii, P. kinabatanganensis, P. lithostoma, detected by palatal teeth set in a solitary huge patch and elevated vertebral reckons. Pangasius (Pangasius) was the final subgenus and had no diagnostic features, containing the remaining species. These vice-common categorizations were chronic in 2000 apart from for Neopangasius, set up to be polyphyletic and to be fraction of Pangasius or Pangasius, hence parting three subgenera.
