本文描述了色林错裸鲤 (Gymnocyprisselincuoensis)的臀鳞、背鳍条磨片和耳石磨片上的生长标志及特征 ,指出色林错裸鲤臀鳞上的繁殖痕迹 ,以及耳石磨片早期生长中出现类似月周期的生长阻断、光镜下透明带中日生长增长的减少甚至消失等现象与色林错裸鲤的繁殖习性及多变的高原环境相关。在 5种年龄鉴定的材料中 ,以耳石磨片上的轮纹特征最为明显、清晰且规律性强 ,是最好的年龄解释材料 ,而鳃盖骨和脊椎骨上都只能观察到少数几个轮纹 ,并不适合用作年龄鉴定的材料。
This article describes the growth marks and characteristics of the naked scales, dorsal fin strips and otoliths of Gymnocyprisselincuoensis, and points out the breeding traces of the naked scales of naked forest carp and the early growth of otoliths In the growth cycle similar to the monthly block, under light microscope, the growth of the zona pellucida decreased or even disappeared and other phenomena and the wrong color carp breeding habits and variable plateau environment. Of the five age-identified materials, whetstone features most clearly, clearly and regularly on otolith disks were the best age-explaining material, with only a few observed on the opercle and vertebra Rim pattern is not suitable for use as material for age identification.
