ObjectivesObjectives

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.
