PurposeResearch
Objectives1. To undertake a beam trawl survey in the southern North Sea and eastern Channel as part of an international programme to:
i) obtain fisheries independent data on the distribution and abundance of commercial flatfish species, and
ii) derive age compositions of sole and plaice for use in the assessment of stock size.
2. To quantify the seabed sediments and epibenthos using trawl by-catch data and remote acoustic seabed discrimination systems (ROXANN/QTC View), in order to describe the association between the substrate and the distribution and abundance of invertebrate by-catch.
3. To collect additional biological data on non-commercial fish by-catch, and on commercially important non-quota species, especially turbot, brill and cuttlefish.
