A sight on the Marine Stewardship Council semi-quantitative analysis applied to an Argentinean fishery

The purpose of this work was to compare availability as a weighted overlap between fishing effort and fish occurrence per statistical square with availability as a simple non-weighted overlap, and to determine the difference on the final calculation of potential risk between both cases following the Marine Stewardship Council Productivity Susceptibility Analysis model. The scenarios considered were the Argentine hake freezer trawl fishery in years 1998, 2005 and 2007. These years were chosen as representatives of variability in environmental and fishing conditions. Results show a significant difference in final potential risk between the weighted and non-weighted cases in all environmental and fishing conditions.
