Abstract
Catch and Effort Data Analysis (CEDA 1.0) is a PC based system provided by the UK Overseas Development Administration for the analysis of catch, effort and abundance index data, giving estimates of current and unexploited stock size and catchability. This system is used to analyse lobster catch and effort data over the period 1957 - 1992. The data series has a number of problems, including significant gaps in the time series. CEDA appears to be effective in obtaining an estimate of the population size at the beginning of each season. Analysis of changes over years is more difficult and requires care in interpretation. The results of the analysis and performance of the package are discussed. CPUE; computer package; depletion model; estimation; stock model.
