Objectives1. To carry out detailed acoustic surveys in selected lochs and the Sound of Sleat using the EK 500 and Roxann to determine the distribution of herring and sprat. Concentrations of pelagic fish will be sampled using the PT 154. Species composition and length frequency distributions of the fish caught will be determined. Sub samples will be weighed and otolithed to establish length weight relationships and age structure. Herring samples will be analysed for sex, maturity and Ichthyophonus infection. Stomacks, DNA samples and photographs will also be taken from selected samples for the EU projects AQCESS, HERGEN and WESTHER.
