Abstract

To quantify the rate of escape of commercially targeted fish underneath the ground gear and through the gaps between the fishing line and ground gear of the GOV trawl used in the North Sea groundfish survey (research vessel), and to calibrate the catch rates on the research vessel to commercial catch rates using commercial gear and practices on commercial vessels.

Lineage

Catch rate comparisons were made between two commercial fishing boats – the *Our Lass II* fishing soft-ground areas (supported by the FSP) and the * Jubilee Quest* fishing hard-ground areas (funded by the fishing industry with a contribution from Defra), and those achieved by the *Cefas Endeavour* using the soft-ground GOV gear. Standardised 2-mile tows were carried out to test if the survey was likely to catch the same portion of the stock as the commercial vessels. The rate of escape of the main commercial species from the standard GOV trawl was assessed by fitting additional nets behind the ground gear to capture escaping fish. The aim was to determine not only the escape rate, but also the factors, if any, that influenced escape.
