| Abstract |
Macropipus holsatus, a common inhabitant of the North Sea, extends its geographic distribution into estuarine areas in spring, withdrawing again in late autumn. These migratory movements were studied during fishery surveys carried out in the years 1961 through 1964 which showed that the distribution within the Wadden Sea is most probably determined by salinity. The migration of the swimming crab out of the Wadden Sea is controlled by tidal transportation triggered by a decrease of salinity. The possible mechanism underlying seasonal inshore and offshore movements is still unknown. |
