Bioeconomic Analysis of Engraulicypris sardella (Usipa) in the South East Arm of Lake Malawi

A study to estimate the maximum economic yield and maximum sustainable yield was carried out for Usipa fishery in south east arm of lake Malawi. We used structured quantitative questionnaire to collect the price of usipa landings and cost of fishing effort. Catch and effort data for Usipa in the south east arm were used to estimate key parameters (r, q and k) of the Gordon Schaefer catch equilibrium model derived from the...
