Taxonomic diversity and eco-exergy changes in fishery resources associated with artificial reefs over 14 years in Daya Bay, China

Marine habitat degradation resulting from human activities and environmental pollution has led to serious deterioration of marine fishery resources. To address this issue, countries worldwide are exploring sustainable approaches. Installation artificial reefs (AR) is rapidly increasing. AR have been widely constructed globally conserve resources improve habitats. As an important biological group resources, nekton evaluated determine the effects ecological restoration resource conservation. In current study, we compared dynamic properties taxonomic diversity eco-exergy community 2 14 years after construction in Dalajia, China. The results indicated that species number density significantly increased construction. Siganus oramin became absolute dominant fish reef area its surroundings. evenness decreased, whereas richness increased. abundance, biomass, over time because dominance fishes. Our highlight can increase structure community, ecosystem stability. But, at same time, S. interfere community. explosive growth was quantitatively qualitatively higher than other species, indices showed a decreasing trend, although background survey CA during period.
