Abstract
The seasonal and local distribution of fish in the Wadden Sea depends on the various modes of life of each species. To obtain nearly all species of the fish fauna and the stages of development in different spatial regions of the Wadden Sea-shallow and deep channels, puddles and pools, sedimentation fields and tidal flats—it is essential to use different fishing methods synchronously. During a two-year monitoring project in 1986 and 1987 on fish and fisheries in a restricted area of the Wadden Sea of Schleswig-Holstein, five types of fishing gear were used synchronously: handnet, push-net, 2-m beam trawl, commercial shrimp trawl, fyke net. In 822 samples of all gear 33 species were caught. No gear obtained the maximum number of species. Day and night samples show considerably different composition. Furthermore, force and direction of wind have an important effect on the distribution of fish in the coastal area. The advantages and disadvantages of the different gear for monitoring purposes are discussed from scientific and practical viewpoints.
