Daily folders (18) of Simrad format (.raw) acoustic data. Echoview format (EV) format analysis files. Excel biological data for 15 pelagic hauls.
Objectives:
To conduct an acoustic survey to estimate the abundance and distribution of herring in the north western North Sea and West of Scotland (ICES area VIa(N) as part of the ICES International North Sea Herring Acoustic Survey.
To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection.
To obtain samples of herring for the HERWAY project.

The survey will be carried out within an area bounded by 55°–60°N and 03°–10°W. Echointegration will be carried out at 38, 120 and 200 kHz on a 24 hour-a-day basis. Data from the times between 2300 and 0300 will not be used for stock assessment. Fish shoals seen on the echosounder will be identified using a pelagic trawl. Trawling operations will be carried out between two and four times per day, and not between 2300 and 0300. Samples of all species caught will be measured for length and weight to establish a length weight relationship. Otoliths will be collected from a sub-sample of the herring to determine age. The maturity state and presence of Icthyophonus infection will also be recorded. Photographs and samples will be taken, for use in the HERWAY project
The survey will involve following a pre-set survey pattern, at normal steaming speed (approximately 10 knots). The survey is timed to allow the southern part of the area to be interlaced with the Irish survey, which is due to start in the northern part of their area at the beginning of July. A port call will take place at an approximate half way stage in Ullapool; to provide a rest day in accordance with working time directive for a trip of this length. It is intended to complete the survey in the north-eastern part of the survey area to coincide with the acoustic survey, by FRV Scotia, in the adjacent area (ICES division IVa).
