| Cruise period | 2003-05-28 — 2003-05-31 |
| Status | Completed |
| Port of departure | Aberdeen, United Kingdom |
| Port of return | Aberdeen, United Kingdom |
| Purpose | Research |
| Objectives | To perform a check monitoring fish disease survey off the Firth of Forth, a reference area (east of Orkney) and at several areas in the vicinity of the Moray Firth. Tissues will be collected from common dab for mixed function oxidase activity and PAH bile metabolities. Grab samples will be obtained from each station and analysed for PAH. A variety of species will be sampled to test as vectors for IPNV and the role of wild marine and freshwater fish in the maintenance and spread of this disease. The distribution and prevalence of this virus will be determined and the genetic relatedness of isolates will form future work. Cod, haddock, turbot, halibut and whiting will be sampled for bacteriology, parasitology and virology to record base line pathogens to model possible interactions with farmed salmonids in terms of disease transfer. Lepeophthirus salmonis negative plankton samples will be collected and used to 'spike' with known amounts of L. salmonis copepodids to determine the lower detection limits of molecular techniques. |
