Das M74-Syndrom des Ostseelachses (Salmo salar): Symptome, Verbreitung und Ursachen
An overview is presented on the M74-Syndrome of Baltic salmon which is known since 1974 and which, since 1992, has caused considerable losses of artificially produced yolk-sac larvae in Swedish and Finnish hatcheries responsible for compensatory salmon stocking programmes. The syndrome only affects...
