基于耳石微化学Sr/Ca的浙江南部近海银姑鱼的生境履历重建
Reconstruction of habitat history of Pennahia argentata in the offshore waters of southern Zhejiang based on otolith microchemical Sr/Ca
摘要
Abstract
The offshore waters of southern Zhejiang serve as an important fishing ground in China,where Pennahia argentata is a common economic fish species.This study explores the habitat of P.argentata in the offshore waters of southern Zhejiang in order to reveal the environmental changes during its individual development.The experiment is based on the otolith samples of P.argentata in this area,and ICP-MS technology is used to measure the Sr and Ca elements in the otolith microstructure.By analyzing the Sr/Ca ratio,it is found that the range of environmental changes for P.argentata habitat is between 3.39×10-3 and 8.12×10 3,indicating the existence of two habitat types:freshwater and brackish water settlement,and brackish-freshwater and seawater mix.In addition,Sr element has been proven to be an effective tracer of the fish habitat history.This discovery not only enriches our understanding of the ecological habits of P.argentata,but also provides a new,feasible,and accurate method and approach for studying the migration routes of P.argentata.关键词
