The introduction of the African catfish Clarias gariepinus (Burchell, 1822) into Brazilian inland waters: A growing threat

Abstract

The biology of the introduced species Clarias gariepinus in lagoa Encantada (Ilhéus, Bahia State) was studied. Samples were obtained with gillnets between May 2002 and February 2004. All individuals caught exceeded the average length at first maturity cited in literature. Males and females in maturation stages indicate that the species is already established in the lake.
