CATFISH, A TRAINING FILM
by Gertjan de
Graaf, Adri Schrover and Linda Lyklema
A simple and
reliable method for the mass production of fingerlings of the African
catfish Clarias gariepinus (Burchell 1822) was developed within
the UNDP/FAO project "The development of rural fish farming in Congo".
Reproduction could be induced throughout the year by using carp
pituitaries. The fertilised eggs were attached to the roots of water
hyacinth and incubated in a cage made of mosquito netting. Three-day-old
larvae were placed in ponds, surrounded by a wall of aluminium roof
plates (0.8 m high). Fingerlings were harvested after 40 days in
order to avoid cannibalism, and an average production of 33 fingerlings/m2
was obtained. Details of this study are published in Aquaculture
Research, 26 (2) 1995.
