This report is based on the results of the work carried out by Mr. Yoel Pruginin, FAO/UNDP(TA) Inland Fishery Biologist (Fish Culture), under an experimental fish culture project in Uganda from February 1965 to December 1966. The project was a continuation and extension of the studies of Mr. Pruginin (1962–64) and the late Mr. A.G. Wurtz (1959–60) described in FAO/EPTA Reports No. 1387 and No. 1960 (FAO/UN, 1961 and 1965).
The expert arrived in Uganda on 11 February 1965 after briefing at FAO Headquarters, Rome. He worked in the country until 3 March 1966, when he left for Israel on home leave and for attending the FAO World Symposium on Warm-water Pond Fish Culture in Rome. He returned to Uganda on 22 June 1966.
On 1 December 1966 he left on a 7-day visit to Rwanda to study the status of fisheries there. On 13 December 1966 he departed for Rome for debriefing and termination of assignment on 31 December 1966.
Under this project emphasis was laid on the field application of the results of experimental studies on common carp (Cyprinus carpio) and Tilapia hybrids carried out at the Kajansi Experimental Station in previous years. The problems encountered in this respect led to a re-evaluation of the fish farming policy in Uganda.
In order to confirm the results of work described in FAO/EPTA Report No. 1960 (FAO/UN, 1965) the earlier pond experiments on fish culture and hybridization were repeated on a larger scale. Increased replication of experiments was made possible by the improvement and enlargement of the fish farm at Kajansi as described in FAO/EPTA Report No. 1960. Further improvements effected after 1964 enabled more intensive studies to be undertaken, with particular reference to Tilapia hybridization and carp reproduction.
