RECONSTRUCTING MIGRATORY HISTORY OF FISH USING OTOLITH STRONTIUM: CALCIUMS RATIOS BY EPMA: A CASE STUDY
基于 EPMA 的耳石 Sr : Ca 比分析及其在鱼类生活履历反演中的应用实例研究

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...
