Abstract

This paper presents data on the length distribution and age composition of male and female dab Limanda limanda as observed in the German Bight in Mar 1990 during the Bremerhaven Workshop. Further data on distribution and seasonal movements from tagging experiments are reviewed with regard to the interpretation of the results of the studies carried out during the workshop. It is shown that highest densities of dab coincided with the main centre of egg production in the inner German Bight. Within the spawning period the spatial distribution changed significantly in a period of 2 wk between mid and late Mar: the abundance of dab increased in the inner German Bight and decreased at the offshore stations. The dab population was dominated by 4 and 5 yr old fish. Growth of dab was higher at the inner stations and on the Dogger Bank compared with the intermediate stations. The results of the tagging experiments suggest that the dab population at one sampling site is a temporary aggregation of fish originating from a large area. The significant change in the spatial distribution between mid-Mar and late Mar implies that even within a period of 3 wk substantial movements of dab occur.
