Improvement of selectivity of trawl cod-ends (REPLACED BY MF0612) - MF0601

R&D Summary Objectives:- Conduct research into the selectivity of trawl cod-ends including design changes and use of square mesh and test these in commercial operations. Key Customer Purpose:- Enable better trawl gear conservation measures to be adopted firstly by the UK and utimately by the EC.
To identify the means by which the selectivity of commercial fishing gears may be improved, taking into account the gear handling arrangements of typical vessels. To quantify the benefits and risks of different options of selectivity devices or arrangements. To devise means of incorporating improved selectivity systems into fishing gears such that the needs of adequate monitoring of the systems can be achieved.
