Introduction of the African Catfish Clarias gariepinus (BURCHELL, 1822) into Southern Brazil

Abstract: We record here the introduction of the African catfish Clarias gariepinus into the Guaraguac¸u River basin in Parana´State, Brazil, an area with an extremely rich endemic fish fauna, including many catfishes. C. gariepinus was introduced as escapees from ponds built for recreational angling. These catfishes are very large and hard predators, thus posing serious potential for impact on the native fish fauna. The impact of C. gariepinus needs study with emphasis on finding means for controlling its spread.

“…They are widely distributed to different parts of African continent being native to streams in the Tolga oasis in Algeria. However, their cultivation in fish farms in Europe, Asia and South America have made them wide spread around the world (Vitule et al 2006). In Nigeria, with an up surge in demand for fish, there is a huge expanding population of C. gariepinus which is the most cultivated catfish in the country aquaculture (De Graaf & Janssen 1996).…”

“…Its network of littoral streams has been poorly investigated (Mazzoni & Lobón-Cerviá, 2000). These streams are among the first environments to suffer from anthropic impacts, potentially threatening their fish fauna (Menezes, 1996;Faria & Marques, 1999;Vitule et al, 2006).…”

“…Estas espécies nativas da África e Ásia foram introduzidas acidentalmente por escapes ou solturas por criadores comerciais ou domésticos em muitas regiões. Potencialmente invasivas estas espécies de bagre podem deixar a água rastejando com a ajuda das nadadeiras peitorais em busca de alimento ou sítio de reprodução, invadindo outros corpos d'água e ameaçando espécies nativas (MILI; TEIXEIRA, 2006;VITULE et al, 2006). Em vários reservatórios torna-se comum o uso de tanques-rede para aquicultura.…”
