| 摘 要： | 利用基于电子探针（EPMA）的耳石Sr：Ca比和Sr含量分析方法研究了长江口水域刀鲚、凤鲚、带鱼和长吻鲍的生活履历及生活史型。结果发现，刀鲚中除存在淡海水洄游性个体生活史型外。还存在出生并生活于河口或近海的非洄游性个体生活史型，其平均耳石Sr：Ca比在不同水环境履历的基准值为：淡水〈2．0×10^-3、河口（3．5—6...

| Abstract: | In this study, the migratory histories of four fish species (tapertail anchovy Coilia nasus and C. mystus, hairtail Trichiurus haumela and longsnout catfish Leiocassis longirostris) in the Yangtze River Estuary, China, were investigated using the otolith Sr:Ca ratios and Sr intensity maps by X-ray electron probe microanalyzer (EPMA). Results showed that, in the C. nasus stock, both river origin anadromous individuals and estuarine origin non-anadromous ones occurred in this area. The otolith Sr:Ca ratios al... |
