| Status | Completed |
| Port of departure | Dublin, Ireland |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Commercial |
| Objectives | To carry out a 4m beam-trawl survey of groundfish 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.
To collect biological data, including maturity and weight at age of sole, plaice, lemon sole and other commercially important finfish species. To determine the distribution and relative abundance of juvenile and adult sole and plaice. To quantify the seabed sediments and epibenthos using 4m beam trawl by-catch. To collect fish samples in support of other CEFAS projects and training courses. |
