ObjectivesObjectives

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'-62°N and from the shelf edge to 2°E, excluding Faroese waters.

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

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

- Collect samples and data for stock identity determination of herring. Photos and otoliths for morphometric stock ID analysis for herring caught west of 4 °W; tissue samples for genetic analysis from herring throughout the survey area.

- Use GoPro cameras mounted in the net and on a drop frame to further aid in species identification in the echogram scrutiny process.

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

- Obtain dissolved oxygen vertical water column profiles for comparison with occurrence of prominent 38kHz scattering layer as part of Aberdeen University Hons student project.

- Collect near-seabed dissolved oxygen measurements for MSS monitoring programme.
