Excel biological data for 10 pelagic hauls. CTD data for 20 vertical dips. 10 daily folders of un-calibrated surface light level data. Objectives: 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 age-length and length-weight relationships. Herring samples will be analysed for sex, maturity, Ichthyophonus and Cryptocotyle lingua infection. Sprat samples will be analysed for Lernaeenicus sprattae, L. encrasicoli and Cryptocotyle lingua infection. Stomach samples will also be taken from both herring and sprat. A line of CTDs will be carried out through each loch. Survey Areas Main survey areas - Loch Carron, Loch Duich, Loch Hourn, Loch Nevis. Secondary survey areas - Sound of Sleat, North Minch.

The survey will work within the sea lochs in a pattern determined by tides. The trip will concentrate on pelagic species and the acoustic survey in the selected sea lochs. If time allows at the end of the trip, zig-zag transects and fishing will be carried out across the North Minch. Where possible contact with commercial fishermen working in the lochs will be made before the start of the cruise to establish the distribution and shooting patterns of the static gear in an effort to avoid damage.
