Cruise Inventory Information

Long name FRV Clupea (74CU) cruise 1597C
Short name 1597C
Objectives and Narrative 1. To carry out an echo-integrator survey to determine the biomass and distribution of pelagic fish in an area off the Firth of Forth encompassing the Wee Bankie and Marr Bank sandeel grounds.
2. To sample areas with high densities of pelagic fish using a pelagic trawl in order to determine fish species, size and age composition and weight-length relationships.
3. To map seabed sediments using RoxAnn, an acoustic survey technique, with associated sediment sampling by Day grab to "groundtruth" the acoustic data.
4. To determine spatial variation in water temperature and salinity depth profiles using a Seabird CTD instrument.
5. To determine the numbers and distribution of avian and mammalian predators in the study area using transect census methods.
6.To determine the abundance and distribution of piscivorous demersal fish species by bottom trawl survey.
7. To assess the length and age composition of these piscivorous fish predators, together with their age-length and length-weight relationships, and to collect stomach samples for diet and food consumption analysis. Also, to examine the livers and gonads (where possible) of these demersal fish for assessment of body condition.
