Surveys of fishermen and fishing activities during 1975,1976 and 1980 show that more than 700 people were part-time fishermen. Large mesh gill nets were used to catch predominantly large cichlid species and catfish. The rota1 annual gill ner catch in 1980 was estimated at more than 700 000 kg but may be considmbly higher. Experimental gill net catches yielded higher catches in the small mesh ners, indicating a resource that was underutilized by the commercial fishery.
