Abstract:
In July - November 2005 and March 2006, Catch Assessment Surveys
(CASs) were conducted at 54 pre-selected fish landing sites in the Ugandan
part of Lake Victoria. These comprised approximately 10% of all landing sites
in each of the 11 districts sharing the lake. Data recording was by
enumerators who were selected from the fishing communities and trained
centrally in CAS procedures following the approved CAS Standard Operating
Procedures (SOPs). Data were captured using regionally harmonised field
sheets, collated at the National Fisheries Resources Research Institute
(NAFIRRI), and analysed to estimate CAS-based indicators for different effort
groups.
The Nile perch catch rates were fairly stable over the period sampled except
in gillnetting boats with motor/sail which showed a significant increase in catch rates in November 2005.
