- Abstract
Characteristics of annual rings on scales, otoliths, vertebrae, opercular bones and cleithra of two loaches, Misgurnus anguillicaudatus and Paramisgurnus dabryanus collected from Zhengzhou city, Henan Province, China, and the precision of age estimations from the five different structures of these two loaches were investigated in this study. Results obtained here showed that: the scale and otolith were suitable for age estimation in M. anguillicaudatus and P. dabryanus; percent agreements of age estimations based on these two different structures for M. anguillicaudatus and P. dabryanus were respectively 81.5 % and 79.5 %; M. anguillicaudatus and P. dabryanus had similar age compositions including five age groups; while the vertebra, opercular bone and cleithrum were not suitable for age estimation of M. anguillicaudatus and P. dabryanus because of their unclear annual rings.
