PurposeResearch
ObjectivesObjectives

1. 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 30 - 62N and from the shelf edge to 2E, excluding Faroese waters. In addition acoustic transects will be carried out in Moray Firth to estimate abundance of herring and sprat.

2. To obtain biological samples by trawling with pelagic and demersal trawl for echosounder trace identification.

3. To obtain samples of herring and sprat for biological analysis, including age, length, weight, sex, maturity, ichthyophonus infection throughout the survey area.

4. Collect samples and data for stock identity determination for herring caught west of 4W (photos and otoliths for morphometric stock ID analysis and tissue samples for genetic analysis).

5. To test feasibility of using GoPro cameras mounted in the net and on a dropframe to further aid in species identification in the echogram scrutiny process.

6. To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring and sprat.

7. To test different deployment scenarios for the Edgetech broadband system with the aim of minimising noise and use the system to collect data on fish schools for ongoing collaborative work with University of Aberdeen.
