New methods for estimating the status of data-poor fisheries

New legislation around the world requires stock assessments not only for the one-quarter of large and valuable fisheries, but also for the three quarters of other commercially exploited marine species. This has revived an interest in less data demanding methods, such as stock reduction analysis (SRA), where the sustainability of catches are analyzed before the background of the productivity of the respective species, and rough estimates of the status of the stocks. The talk will present one such method called CMSY, which has recently been applied to all European stocks with reliable catch data. Also, a new length-based Bayesian biomass estimation (LBB) method will be presented for estimating stock status-such as needed by CMSY and other SRA methods-from length frequency samples from the commercial fishery.

Very informative session. Is it possible if we can get the ppt for the presentation?
