Passany sea catfish

provided by wikipedia EN

The Passany sea catfish[2] (Sciades passany) is a species of catfish in the family Ariidae.[3] It was described by Achille Valenciennes in 1840, originally under the genus Bagrus.[1] It occurs in estuaries and coastal marine waters in Brazil, Venezuela, Suriname, French Guiana, Guyana, and Trinidad and Tobago.[4] It reaches a maximum total length of 100 cm (39 in), more commonly reaching a TL of 50 cm (20 in). It reaches a maximum weight of 15 kg (33 lb).[3] Although not specifically fished for, it is eaten when caught. It may be a host for the parasite Amapacanthus Amazonicus.[4]

The passany sea catfish is currently ranked as Data Deficient by the IUCN redlist, but notes that although the species is not of significant interest to fisheries, it possibly has a slow maturation rate due to its size, which may affect its potential for overexploitation.[4]
