The otolith microstructure of hatchery-breeding and wild-caught Myxocyprinus asiaticus were examined and analyzed. The otoliths of M. asiaticus could be divided into optically dense and low optically dense zones based on the difference of transparence. The otoliths,which had distinct boundary between the optically dense and low optically dense zones,accounted for 63. 16% in hatchery-breeding population and 14. 81% in wild-caught. The size of optically dense zones in otolith of wild and captive M. asiaticus ...
