Excel biological data for 5 pelagic hauls. \r\nObjectives:\r\nTo conduct an acoustic survey designed to survey both the open and enclosed areas of the Clyde to ultimately provide an estimate of the abundance and distribution of herring and sprat.\r\nTo obtain samples of herring and sprat for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection.\r\nAll other species caught will be measured for length and weight to establish a length weight relationship.\r\nTo gather passive acoustic data using a towed acoustic array to assess the presence of cetaceans.",
