Impact of mussel seed fishery on subtidal macrozoobenthos in the western Wadden Sea

Within the framework of PRODUS, the effect of mussel fishery on the macrofauna species sampled with a box-corer was investigated following a so-called split-plot design. Within areas where mussel seed fishery was allowed, 40 plots/locations were chosen within which one part was open for commercial fisheries and one part was closed of fisheries. Box-corers were taken in 21 of these locations, sampled one to several times.
