Abstract

To provide new information on comparative catch profiles of the "eliminator" trawl to those from a conventional trawl fitted with belly cod-escape panels. And to address industry concerns that the "eliminator" trawl is not the only trawl design, which can effectively reduce cod catches in the North Sea.

Lineage

In order to catch fewer cod and thereby service conservation objectives in the North Sea, Grimsby skipper *‘Graham Hall’ * (MFV Jubilee Quest GY900) designed a demersal trawl modification to facilitate cod escapement. This trawl modification consists of an escape panel (mesh size 300 mm) which can be fitted to the belly of standard designs of demersal whitefish trawl which are used by the fishing industry. To evaluate the efficacy of this trawl modification, Cefas scientists and fishing industry members collaborated in this FSP project to compare the catches from the modified trawl (fitted with a belly escape panel) to those from an unmodified trawl of the same design. In this work both trawls were repeatedly towed alongside each other along parallel tracks on commercial fishing grounds in the North Sea. In total, 26 sets of paired-haul catch data were obtained for subsequent analysis. The work was undertaken in July 2009, during two weeks of sea trials in the North Sea aboard two English registered trawlers.
