1. To carry out a trawl survey of the Irish Sea, Celtic Sea and western English Channel 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) Environmental parameters (including CTD profiles and sediment samples) at trawl stations 2. To take photographs and preserve sections of gonadal tissue for microscopic validation of macroscopic maturity staging. 3. To tag and release specimens of spurdog Squalus acanthias, smooth-hound Mustelus spp., tope Galeorhinus galeus, greater-spotted dogfish Scyliorhinus stellaris and other elasmobranchs. 4. To record details of surface sightings of any marine mammals, sea turtles and pelagic fish, and record observations on jellyfish aggregations 5. To sample the epibenthos in ICES divisions VIIf-h with 2m beam trawl 6. To collect a NIOZ core sample from the Irish Sea (54°N 0.1'N 5° 14.9'W) 7. To collect biological samples in support of research projects: (a) Scallop Pecten maximus (to be frozen) (b) Berried edible crab Cancer pagurus (to be frozen) (c) Samples of ling Molva molva (n = 3) (d) Tissue samples of tope (to be preserved in ethanol) (e) Tissue samples from various species of cephalopod (f) Collect and freeze one specimen (head and gills for larger species) of each species encountered Narrative in attached cruise report. |
