Improved selectivity in towed gears - MF0612

R&D Summary Objectives:- Conduct research into the selectivity of trawls including the effect on selectivity of different mesh sizes, twine thickness and the insertion of square mesh panels. Key customer purpose:- Enable better trawl gear conservation measures to be adopted firstly by the UK and ultimately by the EC.
To develop size and species selective towed gears taking into account the practicalities of using such gears on commercial fishing vessels. To quantify the benefits and risks of different options of selectivity devices or arrangements. To consider the requirements of incorporating any such design changes into enforceable legislation such that suitable monitoring systems can be devised.
