PurposeResearch
ObjectivesCruise is in 2 parts: 16 to 25 Oct and 25 Oct to 04 Nov.
1. To 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 PT 154. Species composition and length frequency distributions of the fish caught to be determined. Sub samples to be weighed and otolithed to establish length weight relationships (whole and eviscerated). Herring samples to be analysed for sex, maturity and Ichthyoponus infection. Stomachs and DNA samples to also be taken. Detailed photographs of herring will be taken for future morphometric measurements.
2. To 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 BT 158 trawl and the 2.88 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.
3. To remove kidney samples from as many species as possible throughout the survey area for IPN analysis.
