Purpose | Research |
Objectives | 1. To undertake a beam trawl survey in the southern North Sea and eastern Channel as part of an ICES co-ordinated 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 collect biological data including maturity and weight at age of commercial flatfish and non-commercial fish by-catch. 3. To quantify the epibenthos using 4m beam trawl by-catch data. 4. To carry out detailed survey of sole distribution in selected areas of VIId. |
