1. To obtain information on spatial patterns of abundance of different size- and age-classes of demersal fish in the northern Irish Sea. 2. To obtain abundance indices for the ICES assessments of whiting, haddock, cod and herring. 3. To monitor external parasite loads in whiting and cod, by area. 4. To collect data and samples of sprat and juvenile herring for population/feeding study. 5. To collect samples of flatfish for a feeding study at Port Erin Marine Laboratory. 6. To estimate the biomass of the spawning aggregation of herring on the Douglas Bank using acoustics during one evening. 7. To collect additional data on distribution and abundance of herring and sprat in the eastern Irish Sea, by means of acoustics, to supplement data collected during acoustic survey LF3798. |
