Furunculosis in Lough Neagh Pollan Coregonus pollan, Thompson

Abstract

REPORTS were received during the early part of August 1960 that considerable numbers of Lough Neagh pollan were dying. An inspection revealed that the north-eastern shore in the Antrim Bay area was littered with fish (approximately one for each yard of beach) and from their condition it was evident that the mortality had been occurring for some time, possibly 2–3 weeks. It has since been learned that dying and dead fish continued to be noted until the end of August at least. Although pollen was the only species noted at the time of the inspection, commercial fishermen on the lake have since stated that small numbers of bream, Abramis bramae L., and lake trout, Salmo trutta L., were also affected.
