Objectives and Narrative |
Objectives
1. To carry out an acoustic survey to determine an abundance estimate for sandeels in the in the water column. Three frequencies, 38, 120, and 200 kH were used to aid species recognition. This acoustic survey also produced herring and sprat abundance estimates. Concentrations of fish were sampled using the pelagic trawl to determine species composition and length frequency distributions. Sub samples of the fish caught were weighed and had otoliths removed to establish length-weight relationships and age composition. 2. To carry out a demersal trawl survey to determine an abundance index for sandeels in the seabed sediment. This demersal trawl survey also produced abundance indices for herring and sprats, the two other main prey species, as well as abundance indices for the major piscivorous fish predators in the area, whiting, haddock and cod. At each trawl station, the length frequency of all fish species caught was determined. Sub-samples of sandeels, herring, sprats, cod, haddock, and whiting were weighed to determine length-weight relationships. Otoliths were removed from sandeels and clupeids to determine age composition. Sub-samples of the gadoid predators were retained and frozen for subsequent dietary and age composition analysis if required. 3. Simultaneously with the demersal trawl survey, to carry out hydrographic survey using a Seabird 19 CTD sampler fitted with a fluorometer to determine spatial variation in water temperature, salinity and fluoroescence across the study area. 4. Simultaneously with the acoustic survey, to survey seabirds at sea within the study area using standard census methods. Protection of local breeding seabirds was one of the principal motives underpinning the sandeel fishery closure. 5. Whilst carrying out seabird at sea survey, to record all sightings of marine mammals (number of animals, species if possible, and their location). Narrative Scientific equipment was lo |
