ObjectivesObjectives

1. To assess abundance, length-frequency-distribution, and weight-at-length of demersal fish predators at 19 fixed stations in the area off Wee Bankie by demersal trawl survey. Samples will be retained for stomach analysis later.

2. 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 38 locations on and between the demersal trawl stations.

3. To undertake an acoustic survey of sandeels and clupeid fish in the water column using 38 and 120 kHz. Concentrations of fish will be sampled using the pelagic trawl. Species composition and length frequency distributions of fish caught will be determined. Sub samples will be weighed and their otoliths removed to establish length-weight relationships and age composition.

4. To conduct RoxAnn survey of the substrate along all acoustic survey tracks.

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

6. 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 ring net. CTD transects may also be performed at each deployment.

Procedure

Scientific equipment will be loaded onto Alba na Mara on 1 June at Leith docks. Scientists will join the vessel on the afternoon of Thursday 2 June. Alba na Mara will make passage to the study site the following morning to begin the demersal fish sampling phase of the cruise. It is hoped that between 3 June and the evening of 8 June 19 trawl stations will be fished using the BT158. All of these stations have been fished in previous cruises. Each catch will be worked up to determine numbers at length of all species caught. Trawl performance characteristics will be monitored using Scanmar equipment to enable swept area to be determined.
