|Objectives||1. To participate in the ICES co-ordinated International Bottom Trawl Survey for quarter 1 and in support of the EC Data Collection regulations. To fish over an allocated area of the North Sea using a standard GOV trawl in order to obtain information on:
1) Distribution, size composition and abundance of all fish species caught;
b) Age - length distribution of selected 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 miniCTD;
f) Length, weight and maturity information using individual fish measurements.
2. To collect data and samples to estimate cod reproductive potential as part of the reproduction and stock evaluation for recovery (RASER) project. (P. Witthames, CEFAS, Lowestoft).
3. To collect Scanmar readings from BACA trawl to provide SFIA, Hull, with proofing data for flume tank model.
