Bagarius yarrelli

Bagarius yarrelli

Bagarius yarrelli (local and English called " Goonch " ) is a species from the genus of devil catfish ( Bagarius ) and the mountain catfish family ( Sisoridae ). It comes from the river systems of the Indus and Ganges over large parts of southern India to the Mekong and Xe Bangfai and to Indonesia before. The species is commercially exploited and sold fresh, the meat spoils, however, very quickly and then can cause poisoning. The species is unpopular with anglers because it is strong enough to rip the most fishing lines.

Features

The style is up to two meters in length, the largest species of the genus and family. The head is broad and flattened, with large, wide mouth and four pairs of barbels, one of which has the pair in the upper jaw, a well-educated membrane. Head and Prädorsalplatte have no noticeable ridges. The body has partially a pattern of numerous dark spots. The pelvic fins usually put on after the last ray of the dorsal fin, the adipose fin begins before or about the beginning of the anal fin. The spinous processes of two to five are extended.

Way of life

Bagarius yarrelli inhabited exclusively large rivers and is insensitive to strong currents. The animals usually rest on the ground, partially also in the spray of the rapids. As prey animals are primarily crustaceans, but also fish and insects. The animals migrate in schools and follow it probably their preferred prey, which they partly follow the migrations of the giant barb ( Catlocarpio siamensis ). The main trail starts at the beginning of the rain and flooding time with increasing water flow after the spawning was discontinued prior to the start of the rainy season.
