Lake Victoria fisheries catch assessment survey (CAS) information June 2006

The National Fisheries Resources Research Institute (NAFIRRI), the Department of Fisheries Resources (DFR) and the districts in and around Lake Victoria jointly conduct Catch Assessment Surveys (CAS) with a major objective of providing information on the magnitude of fish catches in the lake. Fisheries contribute as high as 12% to Uganda's GDP. Catch assessment surveys are some of the avenues used to collect information for monitoring fish population dynamics as well as the magnitude, distribution and trends of fishing effort and fish catches. They are necessary for making sound decisions for the management of Lake Victoria fisheries. This information provides the Catch Per Unit of Effort (CPUE). The CPUE is used together with frame survey data to estimate total fish catches
