The Impact of Fishing Pressure on Kapenta (Limnothrissa miodon) Production in Lake Kariba, Zambia: A Case Study of Siavonga District
The purpose of the study was to assess the impact of the fishing pressure on Kapenta (Limnothrissa miodon) production in Lake Kariba situated in the Southern province of Zambia. The study revealed that there was an increase in fishing effort from 423 fishing rigs in 2009 to 800 fishing rigs in 2013. The Kapenta stocks had been greatly overexploited considering that the CPUE had decreased from 0.187tons/boat/night in 2000 to 0.085 tons/boat/night in 2012. Kapenta catches averaged three crates per rig/night (which was equivalent to 60kg (0.06 metric tons) while in the past, catches could go up to as much as ten crates or more per rig/night (about 0.2 metric tons). It was therefore, observed that fishing effort was the major contributing factor towards poor catches being experienced due to high influx of cheaper vessels.
