Conduct an annual fish disease monitoring survey at Moray Firth, Fair Isle, Bell Rock, Marr Bank, Montrose Bank, Wee Bankie, St Abbs using standard ICES protocols for external fish diseases of haddock and dab (i.e. lymphocystis, ulcers, X cell, hyperpigmentation, fat cell necrosis and epidermal hyperplasia). Collect dab liver samples a fix for light microscopy (30 per station, 20-24cm group). A histological examination of the tissues will be carried out in the laboratory. Carry out an internal examination of >25cm dab for indication of liver neoplasia. Disease prevalence data will be prepared and data submitted to MERMAN on return to FRS.
Collect tissues from common dab for mixed function oxidase activity and PAH bile metabolites in line with current monitoring programme. Additional haul and grab samples are planned at the East Buzzard site.
Sample tissue from dragonet, Callionymus lyra in connection with joint histopathology study with Cefas.
Conduct survey of external diseases of whiting (Merlangius merlangus) for potential monitoring including epidermal hyperplasia, Lernaeocera branchialis, Diclidophora merlangi and Clavella adunca.
Collect 10-15 whiting and dissect gall bladders into 100% ethanol. If time is short, whole fish with be frozen.
Collect samples of Lereonocera branchialis. 10-20 specimens each from haddock, whiting and cod (A section from the protruding part of the parasite is suitable). Store in 100% ethanol.
Examine cod, haddock, herring and whiting for evidence of anisakids parasites present in the vent; linked to a current study examining red vent syndrome in wild Atlantic salmon.
Collect live common for laboratory investigation involving hyperpigmentation.
Collect and freeze a selection of squid, sprats, sand eels and prawns for aquarium fish feed.
