    Abstract

    Three data sets have been analysed landing statistics (1903-1993). International Bottom Trawl Surveys (1979-1993), and survey data collected in Dutch coastal waters between 1951 and 1994. Landings of rays and skates have decreased by more than half compared with the post-war level. Starry ray has increased in abundance in the central North Sea between 1970 and 1993. Thornback ray virtually disappeared from the Dutch coastal area in 1958. No significant trend has been observed for the other species.
