1986 Eastern Irish Sea Groundfish Survey Catch Data from the Silver Star

Three groundfish surveys were conducted from the vessel Silver Star in the eastern Irish Sea in 1986. The data records numbers at length by centimetre for main commercial fish species and includes station positions by area. A summary table for two of the cruises contains catch data for all other species.
