    "description": "Hard copy of daily EK500 echogram print outs. Paper record trawl summary sheets for 12 pelagic, 4 demersal and 10 beam trawl tows. Excel biological data for 12 pelagic hauls. CTD data for 10 vertical dips.\r\nObjectives: \r\n1.\tTo carry out detailed acoustic surveys in selected lochs, using the EK 500 to determine the distribution of herring and sprat. Concentrations of pelagic fish to be sampled using the PT154. Species composition and length frequency distributions of the fish caught to be determined . Sub samples to be weighed and otilithed to establish length weight relationships (whole and eviscerated). Herring samples to be analysed for sex, maturity and lchthyoponus infection. Stomachs and DNA samples to also be taken. Detailed photographs of herring will be taken for future morphometric measurements.\r\n\r\n2.\tTo carry out demersal trawls in Lochs Kishorn, Duich, Hourn, Nevis and Sunart as part of the Aqcess program, to determine the abundance, distribution and variation of fish species and any epibenthic mega-fauna using the BT158 trawl and the 2.8 m beam trawl where appropriate. At each trawl station the length frequency of all species to be taken and sub samples of the major commercial species weighed (whole and eviscerated) and otolithed. Stomach contents to be removed from selected species for trophic studies.\r\n\r\n3.\tTo remove kidney samples from as many species as possible throughout the survey area for IPN analysis .",
