Such as the case with silurid fishes, it is almost impossible to hand strip the sperm from the male of African catfish, Clarias gariepinus. Therefore and as seen in this video, testes of a sacrificed male are used for the artificial fertilization of catfish eggs. Testes are macerated (cut) and sperm is directly released and mixed with the stripped eggs from a catfish female.
