Biologie     Glossaire (ex. epibenthic)

Adults occur in lentic and lotic freshwater bodies (Ref. 7300). They inhabit turbid water of gently flowing rivers and waterholes. Capable of withstanding high temperatures and brackish water conditions (10 ppt. salinity). Carnivorous, feed on small fishes, crustaceans and worms. Breed during summer flooding; pelagic eggs are released after an upstream migration and hatch in about 30 hours. Eggs are guarded and fanned by the male parent (Ref. 205). Sexual maturity is reached at a length of about 24-28 centimeters. One of few good angling species available in the arid interior of the continent (Ref. 44894).
