Abstract
    In the Dutch Wadden Sea a whelk fishery existed from 1900 to 1970. The high post-war catches, following a period without fishery, and the subsequent decrease in catches when fishery was reopened, allowed us to estimate fishery mortality and recruitment. Information on natural mortality and growth, which were required in the estimation procedure, was obtained from previous studies elsewhere. Natural mortality could be calculated from an experiment with marked whelks in the Thames estuary. Age-length relations could be used from French investigations on whelks near the Channel Islands. The size of a potential whelk population could be estimated. Effects of fishery and possible causes of the disappearance of the whelk from the Dutch Wadden Sea are discussed.
