1. A method to evaluate selection of Antarctic krill in towed fishing gears

   Abstract:  The pelagic trawlers involved in the fishery for Antarctic krill (Euphausia superba ... ) apply different trawl designs. Very little information exists on the size selectivity of E. superba ... is valuable information for the management of harvested marine stocks. Size selectivity data is ... traditionally collected during timely and costly fishing experiments in the field where one design is tested at ...

8. Depletion-corrected average catch: a simple formula for estimating sustainable yields in data-poor situations

   Abstract:  The depletion-corrected average catch (DCAC) formula is an extension of the potential ... -lived species. Over an extended period (e.g. a decade or more), the catch is divided into a sustainable ... biomass. The size of the windfall is expressed as being equivalent to a number of years of sustainable ... production, in the form of a “windfall ratio”. The DCAC is calculated as the sum of catches divided by the ...
