Benthic Environment Effects of Aquaculture Activities in Sansha Bay Based on Different Biological Indices

Abstract

Sansha Bay is one of the most typical aquaculture bays in the East China Sea. It is of great significance to study the benthic environment effects of aquaculture activities in Sansha Bay. At present, the overall number of studies in this area is relatively small. In order to study the benthic environmental effects of aquaculture activities in Sansha Bay, different scholars have tried to explain the ecological effects of aquaculture activities from different perspectives. The purpose of this paper is to study the benthic environmental effects of aquaculture activities in Sansha Bay based on different biological indices. In the experiment, the Shannon-Wiener diversity index and AMBI biological index calculation formula are used to analyze and investigate the environmental quality. The experimental results show that the results of AMBI and BAMBI in Sanshawan are similar. The average value of AMBI in Sanshawan is 3.41, while that of BAMBI is 3.38. The average value of BAMBI index is lower than that of AMBI index, and both of them are rated as good environmental quality.
