Objectives | 1. The main aim of the cruise will be to study the recruitment of 0-group
plaice into Red Wharf Bay and their subsequent mortality. This will be
done by regular sampling every few days on standard lines off the beach
and parallel to the beach with the 4 metre beam trawl and push net.
2. A study of predation on 0-group plaice by the collection of larger fish for
stomach content analysis using the otter trawl and beach seine as well as
the 4 metre beam trawl.
3. Tank experiments on predation and digestion rates (part a) .
4. Trials of air-lift apparatus for sampling benthos and plankton (a).
5. Gear trials to assess the efficiency of the 4 metre and 2 metre beam trawls
on the smallest 0-group fish (b and c).
6. Comparison of catches of metamorphosing post-larvae with the beam trawl and
the sledge net towed by CLIONE (b) (see also programme of CLIONE Cruise 4).
7. To service the Plessey current meters off Red Wharf Bay as necessary. |
