ObjectivesThis cruise is in 2 parts. Part 1: 08-24 Nov 2004; Part 2: 25 Nov - 09 Dec 2004.
1. To carry out a trawl survey of the Irish Sea, Celtic Sea and western English Channel (ICES divisions VII a, e-j), 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 invertebrate;
b) age-length distribution of selected species for ICES WG input and biological studies;
c) biological parameters of selected species.
2. To continue the testing of the modified GOV trawl with rockhopper groundgear on hard grounds off Cornwall and in St George's Channel.
3. To continue the development and testing of electronic data capture equipment and the new Fishing Survey System.
4. To collect sediment samples at trawl stations.
5. To sample areas of VIIg-h with 2m and 3m-beam trawl to quantify epibenthos and fish.
6. To record any interesting biological observations regarding rare and unusual fishes, and sightings of cetaceans.
7. To collect biological material for the following projects/courses:
a) whole individuals of selected fish species should be frozen for fish identification courses;
b) whole individuals of scallops Pecten maximus should be frozen (D. Palmer, CEFAS);
c) tissue samples from rays (Rajidae) should be preserved for molecular studies (M. Chevolot, University of Groningen/J.Ellis, CEFAS);
d) tissue samples from spurdog Squalus acanthias should be preserved for molecular studies (J. Franks, University of Washington/J.Ellis, CEFAS);
e) fecundity samples from hake Merluccius merluccius (P. Witthames, CEFAS).
