ObjectivesObjectives

1. To undertake an acoustic survey of clupeid fish (and sandeels if present) in the water column using 38 and 120 kHz. Acoustic survey will be undertaken on route from Fraserburgh to the Tay. The standard six transects across the Wee Bankie, Marr Bank and Berwick Bank will be surveyed. Then transects surveyed in the outer Firth of Forth in November 2010 will again be steamed. Concentrations of fish will be sampled using the pelagic trawl. This survey work will be undertaken during the day between 0600 and 1800.

2. To conduct RoxAnn survey of the substrate along all acoustic survey track.

3. To conduct seabird at sea survey and survey of marine mammals along the acoustic survey track.

4. To assess abundance, length-frequency-distribution, weight-at-length, age-at-length and maturity-at-length of 2+ aged sandeels at previously established stations on the Wee Bankie, Marr Bank, Berwick Bank, and St Andrew's Bay using the sandeel dredge (undertaken at night between 1800 and 0600).

5. To assess abundance, length-frequency-distribution, weight-at-length, age-at-length and maturity-at-length of 1 group sandeels at each visited dredge station by means of random drift Day grab survey (undertaken at night between 1800 and 0600).

6. To assess abundance, length-frequency-distribution, and weight-at-length of demersal fish predators at 19 fixed stations in the area by demersal trawl survey. Stomach samples will be collected from the principal sandeel predators to assess diets and consumption rates.

7. To sample variation in water temperature, salinity and fluorometry through the water column using a Seabird CTD sampler at all demersal trawl stations and at approximately 24 locations between the demersal trawl stations.

8. To assess variation in the abundance and composition of the zooplankton community through a combination of acoustic survey and sampling using both the dual bongo net and the 1m
