| Purpose | Research |
| Objectives | 1. 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 collect biological data including maturity and weight at age of commercial flatfish and non-commercial fish by-catch. 3. To collect samples of dab and whiting tissue for nitrogen stable isotope analysis. 4. To carry out a detailed survey of sole distribution in selected areas of VIId. |
