Abstract

The post-mortem findings in 38 stranded harbour porpoises during the period 23rd March 1983 to 25th June 1986 in The Netherlands results in a general view about the parasitological status and the organic diseases in these animals. The observations concur with those in caught animals described by Andersen (1978) and by Clausen & Andersen (1988).

The observations (3 x ) of roundworms in the skull sinus around the equilibrium organ may be a signal for further investigations in this part of the body.
