Descripción
As a continuation of a hydroacoustic training in 2013 supported by SmartFish FAO, and in accordance with recommendations of the Fifth Technical Consultation on Development and Management of the Fisheries of Lake Kariba, SmartFish FAO supported a hydroacoustic survey in August 2014. The preliminary results of the survey that was undertaken to determine the standing biomass of Kapenta in Lake Kariba show that by adding the estimated biomasses of the basins and stratum, the estimated average standi ng biomass was 16,277 i.e. ± 9,730 tonnes. In order to ascertain any changes over time and to draw substantial conclusions, comparisons across time is necessary. A regular hydroacoustic survey programme will have to be established and the relationship between densities and environmental parameters should be assessed.
