1. Perform fish disease survey in the Moray Firth, east of Orkney, Bell Rock and St Abbs using standard ICES protocols. 2. Conduct annual fish (haddock, dab) disease survey at Moray Firth, east of Orkney, Bell Rock, Marr Bank, Wee Bankie and St Abbs using standard ICES protocols for external fish diseases (i.e. lymphocystis, ulcers, X cell, hyperpigmentation, fat cell mecrosis, epidermal hyperplasia). Collect dab liver samples for light microscopy (50 per region, 20-24cm group). Determine prevalence and report fish data to ICES. 3. Conduct baseline survey of external diseases for whiting (Merlangius merlangus) for monitoring purposes i.e. epidermal hyperplasia, Lernaeocera branchialis, Diclidophora merlangi and Clavella abunca. 4. Collect tissues from common dab for mixed function oxidase activity and PAH bile metabolites. 5. Conduct study on liver and other tissue histopathology from dragonet, Callionymus lyra. 6. Examine Lernaeocera infected and uninfected gadoids for infection by trypanosomes. 7. Prepare images of parasites from the examination and dissection of gadoids and other fish species. 8. Collect tissues from common dab for mixed function oxidase activity and PAH bile metabolites. Narrative FRV Scotia will work in the Moray Firth, east of Orkney, Bell Rock, St Abbs, Wee Bankie and Marr Bank obtaining fish samples by trawling. The cruise will start and terminate in Aberdeen. FRV Scotia sailed from Aberdeen on 1 June at 0800 and commenced trawling in the Moray Firth in the vicinity of the Beatrice oil platform during the late afternoon (1500). Sampling was undertaken at Fair Isle on 2 June, and later in the East Buzzard Control area. Sampling commenced at Montrose Bank on 3 June, followed by Marr Bank, St Abbs Head and Wee Bankie. Bell Rock was sampled on 4 June. A total of 11 trawls were successfully completed. |
