| Abstract |
The abundance of black spot disease of brown shrimp (Crangon crangon (L.)) was investigated in the German Bight from 1986 to 1988. Highest prevalences of these cuticular lesions were found in the inner German Bight, mainly in the estuaries of Elbe and Weser, with a maximum infection rate of 58%. Prevalence of disease was higher in larger specimensthan in smaller ones. Disease intensity and infection rate were highest in late summer and autumn. |
