PurposeFisheries
Objectives1) To conduct an acoustic survey to estimate the abundance and distribution of herring in the north western North Sea and north of Scotland between 58-61.45'N and 4.0W to 2.0E, Faroese waters.
2) To obtain echosounder trace identification using pelagic trawl and demersal trawl.
3) To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection.
4) To obtain samples of herring for genetic analysis for HERGEN.
5) To obtain photographic records for fish maturity analysis.
6) To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring.
7) To obtain plankton samples for acoustic identification work.
