Summary:Methodology for assessing squid fisheries is presented focusing on the estimation of exploitation rate, stock size and the fishing power of the vessels. The assessment is designed to provide input into management decisions for effort limited fisheries. The fishery for Illex argentinus around the Falkland Islands is used as an example for the methods. The development of a management policy for this fishery is described more fully in a related paper. The methods are based on modifications to standard Leslie-Delury analysis. Various regression methods are utilized depending on the number of fleets for which detailed data are available. The statistical procedures also yield estimates of the standard errors of the estimates for evaluating the assessment advice.
