PurposeResearch
Objectives1. To carry out detailed acoustic surveys in selected lochs, the Sound of Sleat and North Minch (if time allows) using the EK 500 to determine the distribution and abundance 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 otolithed to establish length-weight relationships. Herring samples will be analysed for sex, maturity and Ichthyophonus infection. Stomach, gonad and DNA samples will also be taken, as part of the EU project WESTHER. Sprat samples will be analysed for Lernaeenicus sprattae and Cryptocotyle lingua infection.
2. A line of CTDs will be carried out through each loch.
