ObjectivesTo carry out an echo-integrator survey to determine biomass and distribution of pelagic fish in the Moray Firth. Trawling was carried out in areas with high densities of pelagic fish in order to determine fish species and size composition, weight-length relationships and to collect samples of herring, sprat and sandeels for subsequent diet analysis in the laboratory. To determine the numbers and distribution of mammalian and avian predators using transect census methods. To determine spatial variation in water temperature and salinity depth profiles using a CTD recorder and to collect water samples for nutrient, chlorophyll and radio isotope analysis. To determine spatial variation in zooplankton density using Dutch Gulf III and Methot net samplers.
