Objectives1. To carry out an acoustic survey, backed up by pelagic trawling, to determine the biomass and distribution of pelagic fish in the inner Moray Firth and in an area off the Firth of Forth which included the Wee Bankie and Marr Bank.
2. To assess the abundance and distribution of seabirds in both study areas using standard transect census techniques.
3. To locate, in the Firth of Forth study area, the feeding sites of radio tagged kittiwakes, guillemots and shags breeding on the Isle of May.
4. To record the location of all marine mammals observed at sea.
5. To map seabed sediment type using the acoustic system, RoxAnn, and to collect sediment samples to "groundtruth" the RoxAnn data.
6. To determine spatial variation in the water temperature and salinity profile within each study area.
7. To carry out a bottom trawl survey to determine the abundance, distribution and length composition of piscivorous demersal fish species in each study area.
8. To collect stomach samples from piscivorous fish to determine spatial variation in their diet.
9. To determine weight-lenth relationships for each fish predator species, and examine spatial variation in fish condition.
