Fishing gear-induced skin ulcerations in Baltic cod, Gadus morhua L
In 1982 a high prevalence of skin ulcerations was observed in Baltic cod in the vicinity of the Danish island of Bornholm. In March the prevalence varied from G to 13%, and in May it had increased to between 26 and 48%. The ulcerations had a sequential development. The initial stage appeared as seve...
