| Objectives | 1. To participate in the ICES International Young Fish Survey.
2. To sample post-larvae herring, sprat and eel, and make volumetric assessments of krill using the Isaacs Kidd midwater trawl (IKMT). 3. To take temperature readings and collect salinity and nutrient samples at the surface and near bottom at each bottom trawling location. 4. To make one bottom trawl haul in each rectangle of sub-areas 61, 62, 65 and 66. 5. To compare catch rates made with a 1.4 m sq Method IKMT with those of a standard IKMT. 6. To sample stomach contents of principal predators, especially cod and whiting, to investigate feeding and prey selection. (P Bromley) 7. To provide fish samples for contaminant analysis for inclusion in the North Sea Task Force Quality Status Report. (A Franklin) 8. To replenish stocks of specimens for fish identification courses. (A Watson) 9. To recover, and relay a tetrapod off the Tyne. (Dr R Dickson) 10. To collect herring for a parasite tagging project. (Dr McKenzie, DAFS) |
