Abstract

A statistical sampling method is described to estimate the annual catch of silver kob Agryrosomus indorus by recreational shore-anglers in Namibia. The method is based on the theory of progressive counts and on-site roving interviews of anglers, with catch counts and measurements at interception, using data taken during a survey from 1 October 1995 to 30 September 1996. Two different methods of estimating daily catch were tested by sampling the same population of anglers using a complete and an incomplete survey. The mean rate estimator, calculated by the ratio of the means with progressive angler counts and averaged fishing times, provides the best estimate of daily catch.
