The report provides catch records for the Kapenta and inshore fisheries in the Zimbabwean waters of Lake Kariba for the year 1994. Kapenta usually constitute about 90% of the total catch from Lake Kariba; for statistical purposes catches are recorded for the 5 hydrological basins - Mlibizi, Binga, Sengwa, Bumi and Kariba. Whereas kapenta represent a unit stock which is harvested by both Zimbabwe and Zambia, the artisanal fishery exploits inshore species which generally occupy water less than 10m deep along the shoreline, considered to be 2 separate stocks. The main species in the inshore fishery are Oreochromis mortimeri, Sargochromis codringtonii, Tilapia rendalli, Labeo altivelis, Hydrocynus vittatus, Mormyrus longirostris, Clarias gariepinus and Synodontis zambezensis.
