PurposeFisheries
Objectives1. To carry out a groundfish survey of the North Sea using a standard GOV trawl in order to obtain information on:
(a) Distribution and abundance of all fish species.
(b) Length and age distribution of commercially important species.
(c) Distribution of fish in relation to their environment.
(d) Distribution of macrobenthos and anthropogenic debris.
(e) Surface and bottom temperature and salinity data using reversing bottles.
2. To carry out a full-scale trial of length and biological data recording using the electronic data capture system.
3. To collect material for fish identification courses. (T Watson)
4. To collect all hake under 30cm for otolith structure studies. (T Watson)
5. To provide fish samples for contaminant analysis. (A Franklin, Burnham)
6. To inspect herring (Clupea harengus) for the presence of Ichthyophonus and to preserve any infected fish. (S Feist, Weymouth)
