Comparison of Fish Assemblages in Gyeonggi Bay, Korea between 1999 and 2015

Abstract

Fish assemblages of the Gyeonggi Bay were compared based on the fence net monthly surveys from 1999 (March-August) and 2015 (March-August). Both cluster and non-metric multidimensional scaling (nMDS) analyses of the fish assemblages in the sampled months in the two surveyed periods showed higher similarity among the sampled months of each year than that of between years. Number of species and species richness of assemblages were higher in 2015, while the species diversity and evenness were higher in 1999. These results may relate to habitat changes due to by human or environmental impacts such as, fisheries and climate warming.
