DEVELOPMENT OF TILAPIA FEEDS
Preparation of this Report
This report was prepared during the course of the project identified on the title page. The conclusions and recommendations given in the report are those considered appropriate at the time of its preparation. They may be modified in the light of further knowledge gained at subsequent stages of the project.

|This report details the results of a consultancy carried out to develop Tilapia (Oreochromis niloticus) feeds for use at the Project's fry production centres and by small-scale farmers in the Lake Basin Region. The current feeding strategies employed by the Project and local farmers are critically reviewed and recommendations given for an improved semi-intensive pond using feeding strategy using locally available feed resources. Particular attention is given to the improvement of on-farm feed and fertilizer management techniques so as to reduce feed wastage and maximize fish production at minimum cost. Details of the existing and recommended dietary formulations and feeding regimes are fully described.|
The consultant would like to thank Mr. R.S. Prayitno (Project CTA), Mr. A.P.Achieng (Project NPC) and Mr. S.B. Obura (Managing Director, Lake Basin Development Authority) for their constant encouragement and support. Particular appreciation must be given to Ms. P. Achieng (Fish Biologist NPPP) and Mr. S.K. Obuya (Fisheries Officer LBDA) who acted as counterparts for the consultancy. Sincere appreciation is also extended to the many persons who kindly supplied information contained in this report (see Annex 1), and in particular to Mr. E.L.Karstad (Director, Tamfeeds Ltd., Nairobi), Mr. P. Oloo (Branch Manager, Unga Feeds Ltd., Nakuru), and Mr. W.W. Shisoka (Technical Adviser for East Africa, Roche Ltd., Nairobi).
