Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RV Corystes (74RY) |
| Cruise identifier | COR10/96 |
| Cruise period | 1996-07-31 — 1996-08-16 |
| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | 1. To undertake a beam trawl survey as part of an international programme in the North Sea and Channel 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 additional biological data on non-commercial fish by-catch, and on commercially important non-quota species, especially turbot, brill and cuttlefish, to improve our knowledge of these poorly studied species. 3. To quantify the seabed sediments and epibenthos using both photographic and trawl by-catch data, and also the ROXANN acoustic seabed discrimination system, in order to describe the association between the distribution and abundance of invertebrate by-catch, and the substrate type. These data will enable us to more accurately assess the impact of towed gears on invertebrate populations. |
