PurposeResearch
Objectives1. To carry out detailed acoustic surveys in selected lochs and bays on the mainland side of the North Minch and southern Skye using the EK 500 and SEABAT to determine the distribution and abundance of juvenile 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.
2. For each haul from which stomachs are taken a vertical plankton net dip will be carried out.
3. A series of CTDs will be carried out through each loch and bay sampled.

Measurements 
Physical oceanography 
CTD stationsQuantity: number of profiles = 40
Description: CTD deployments using SEABIRD 911plus. In each area and loch a CTD was carried out at the centre point of each tow. A number of CTD dips were then carried out through each loch to determine vertical structure throughout.
Biology and fisheries 
NektonQuantity: number of measurements = 10
Description: Pelagic Trawls. The mini-logger was deployed on the headline during each trawl, along with the Scanmar sensors. Hauls carried out up to a water depth of 152m and a duration of 33 minutes. Approx 96 baskets collected overall.
