Aims:
1) To carry out a trawl survey of the Celtic Sea, to obtain information on:
a) distribution, size composition and abundance of all fish species;
b) age - length distribution of selected species;
c) the detailed distribution of spawing cod (Gadus morhua) in the NW of ICES Division VIIg (Celtic Sea);
d) collect biological data in support of the EU Data Collection Regulation.
2. To sample juvenile fish for recruitment studies.
3. To collect material for fish identification courses.
4. To collect and preserve frozen, all scallops (Pecten maximus) that are caught.
5. To continue the development and testing of electronic data capture equipment.
6. To collect plankton samples in order to estimate onset of mackerel (Scomber scombrus) spawning (S. Milligan).
7. To collect hake (Merluccius merluccius), mackerel (Scomber sombrus) and horse mackerel (Trachurus trachurus) maturity and fecundity material (P. Witthames).
8. To obtain length distributions of mackerel within the Mackerel Box (C. Darby).
9. To investigate the use of a 2/3m beam trawl for obtaining juvenile fish samples (Jim Ellis).
10. Tag and release specimens of spurdog (Squalus acanthias), smoothhound (Mustelus spp.), greater spotted dogfish (Scyliorhinus stellaris) and tope (Galeorhinus galeus).
