Objectives1. To carry out detailed acoustic surveys in selected lochs and the Sound of Sleat using the Seabat 602 to determine the distribution of herring and sprat. Concentrations of pelagic fish will be sampled using the PT154. Species composition and length frequency distributions of the fish caught will be determined. Sub samples will be weighed and otilithed to establish length weight relationships. Herring samples will be taken for DNA analysis.
2. To carry out demersal trawls in each of the sea lochs to determine the abundance, distribution and variation of fish species and any epibenthic mega-fauna using the BT158 trawls and the 2.8 m beam trawl where appropriate. At each trawl station the length frequency of all species will be taken and sub samples of the major commercial species will be weighed and otiliths taken. Stomach contents will be removed from selected species for trophic studies, the carcasses will be bagged and frozen for parasitic analysis. In addition where possible 100 skin samples per selected species per location will be removed for genetic studies.
