The Use of Square Mesh Selector Panels as a Means of Improving Selectivity of Demersal Towed Fishing Gear

Summary

Three series of trials with square mesh windows are described, all of which took place in the first half of 1990 off the NE Scotland, Orkney and Hebrides. The trials were a combination of comparative hauls and film using the DAFS-RCTV. The first on 'CLUPEA' showed clearly the benefits of the square mesh in releasing undersized fish and gave confidence to proceed to a commercial trial on the seiner 'KESTREL'. Finally more RCTV film and further refinements were made on a trial on the 'ST. KILDA'.
