ANOU IS RAISING 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.

An instruction film (50 minutes, French) was made in order to propagate this production technique. The film follows Anou, a student who wants to learn how to produce fingerlings. Anou executes a complete rearing cycle and all steps in the production cycle are visualised and explained in detail.

The film has been made as part of the UNDP/FAO Fish Farming Development Project in the Republic of Congo.

The film is available free of charge on CD-ROM.

The original film is in french, but a subtitled english version is available now
