| Status | Completed |
| Port of departure | Belfast, United Kingdom |
| Port of return | Belfast, United Kingdom |
| Purpose | Fisheries |
| Objectives | Demersal young fish survey (summer)
1. To obtain indices of abundance of juvenile godoids to facilitate predictions of stock-size and yield of recruited fishin future years. 2. To investigate the diets of predatory fish species in relation to the distribution and relative abundance of their fish prey, with particular emphasis on predation on commercial species. 3. To obtain further information on distribution of different age-classes of fish to facilitate interpretation of data from commercial catches. 4. To obtain samples of zooplankton and '0'-group fish for studies of the ecology and early life history of Irish Sea fish. 5. To collect samples of squid and weever fish for projects based at UUC and PEML |
