临海东矶海域人工鱼礁大型底栖动物群落的早期发育
Early development of epibenthic macrofauna communities on the Dongji artificial reefs,Linhai,Zhejiang Province
摘要
Abstract
As efforts to recover fishery resources and restore the damaged coastal ecosystems,artificial reefs(ARs)were often anchored on the seafloor in coastal zones to provide new habitats for marine organisms.The aim of this study was to describe the species compositions,densities,biomass,and structure of epibenthic macrofauna communities on the Dongji artificial reefs,Linhai,Zhejiang province.Seventeen species of epibenthic macrofauna belonged to five taxa were recorded from the Dongji ARs in May(10 months post-deployment)and October(15 months post-deployment),2022.The oyster Talonostrea talonata and the anemone Anthopleura sp.dominated the epibenthic macrofauna communities on the ARs.Among the seventeen species of epibenthic macrofauna recorded in this study,twelve were lithofacies species,while the other 5 species(such as Marphysa sanguinea,Perinereis nuntia,Tritonoharpa leali,Hemicentrotus pulcherrimus,and Ophiura kinbergi)also preferred to inhabit natural rock reefs and oyster reefs.The study showed that Dongji ARs enriched the local soft-bottom biological community and improved habitat heterogeneity and biodiversity.The average densities and biomass((10056±1858)ind./m2 and(8300±2045)g/m2)of the epibenthic macrofauna communities were significantly greater in 15 months than in10 months((3519±289)ind./m2and(3657±273)g/m2).The similarity analysis suggested that the epibenthic macrofauna communitis on the ARs varied significantly with the submersion time(10 months vs 15 months)(Globe R=0.573,P=0.029),which resulted from Obelia genicutata,Anthopleura sp.,Didimarca tenebricum,Tritonoharpa leali,Barbatia bistrigata,and Thais clavigera.The study concluded that the Dongji ARs supported the low species diversity and high densities of epibenthic macrofauna communities,and developed as the artificial oyster reefs through the reef-building oyster Talonostrea talonata.关键词
