This paper studies the effect of the reduction in the trawling effort of large beam trawlers (>300 hp) in the coastal waters of the south-eastern North Sea following the establishment in 1989 of a protected area, the “plaice box”, using data from annual beam trawl surveys carried out since 1985. Two different aspects of the demersal fish assemblage were analysed: (1) the size distribution using multiple analysis of variance; and (2) the species composition using multivariate techniques such as principal component analysis, multidimensional scaling and multiple analysis of variance.
