1. To carry out a trawl survey of the Irish Sea, Celtic Sea and western English Channel (ICES divisions VII a, e-j), using the modified GOV trawl with rockhopper ground gear on hard grounds and standard IBTS GOV trawl on fine grounds, as part of the west coast IBTS series and in support of the EU data regulations, to obtain information on: (a) Distribution, size composition and relative abundance of fish, cephalopods, and benthic invertebrates (b) Age-length distribution of commercial fish species for ICES WG input and biological studies (c) Biological parameters of selected species (d) Presence of litter (e) Environmental parameters (including CTD profiles) at trawl stations 2. To take photographs of (a) fish species for the Photo-ID guide; (b) maturity stages of plaice (1 per cm for each sex). 3. To undertake comparative trawl sampling with RV Corystes. 4. To tag and release specimens of spurdog Squalus acanthias, smooth-hound Mustelus spp., tope Galeorhinus galeus, greater-spotted dogfish Scyliorhinus stellaris and selected skates and rays. 5. To collect information on the body dimensions of spurdog (and other dogfish) and post-mortum changes in length. 6. To collect otoliths from selected fish species. 7. To collect fishery acoustics information. 8. To record details of surface sightings of any marine mammals, sea turtles and pelagic fish, and record observations on jellyfish aggregations. 9. To collect tissue samples from skates (Rajidae), cod, brill and turbot for genetic analyses. 10. To collect the valves of scallop Pecten maximus. 11. To freeze any specimens of corkwing wrasse Symphodus melops. 12. To collect and cryopreserve biological material from fish species, and freeze or photograph voucher specimens of fish species. 13. To sample the epibenthos in ICES Divisions VIIe-h with 2 m beam trawl. Narrative in attached cruise report. |
