PurposeResearch
Objectives1. 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) Environmental parameters (including CTD profiles and sediment samples) at trawl stations
2. To tag and release specimens of spurdog Squalus acanthias, smooth-hound Mustelus spp., tope Galeorhinus galeus and greater-spotted dogfish Scyliorhinus stellaris.
3. To sample the epibenthos in ICES divisions VIIf-h with 2m beam trawl
4. To record details of surface sightings of any marine mammals, sea turtles and pelagic fish, and record observations on jellyfish aggregations
5. To undertake scallop sampling in the eastern English Channel (C2282)
6. To collect biological material in support of research projects:
a) Samples of sprat Sprattus sprattus and anchovy Engraulis encrasicolus should be collected at various sites in the survey area (where n=100 per sample) and frozen for genetic studies
b) Samples of scallop Pecten maximus should be frozen (D. Palmer, Cefas)
c) Samples of berried edible crab Cancer pagurus should be frozen (D. Eaton, Cefas)
d) Samples of a wide range of invertebrates should be preserved in ethanol for genetic studies (C. Fox, Cefas)
