Improved Selectivity in Towed Gears - Sea Trials to Evaluate Selectivity of Separator Trawls used to catch Mised White Fish Species

Summary

The trials described were designed to evaluate the effectiveness and investigate the selectivity aspects of a separator trawl designed to separate cod and fleetfish from other demersal roundfish species. Using a twinning arrangement, two identifcal separator trawls were towed side by side. One net rigged with small mesh codends provided selectivity data when randomly compared against two test codends (100m & 140m). This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies. In cases where this affects the technical content, a paper copy of the original report can still be obtained from Seafish.
