    "description": "12 daily folder of Simrad format (.ek5)acoustic data . CTD data for 39 vertical dips. minilogger data for 10 deployments. 11 surface light level files. \r\nObjectives:\r\n1.\tTo 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.\r\n\r\n2.\tFor each haul from which stomachs are taken a vertical plankton net dip will be carried out.\r\n\r\n3.\tA series of CTDs will be carried out through each loch and bay sampled.\r\n \r\nSurvey Areas:\r\nSummer Isles area/Little Loch Broom; Lochs Hourn, Kishorn, Nevis; the west of Mull including Lochs Tuath, na Keal and Scridain.",
