本文对色林错裸鲤 (Gymnocyprisselincuoensis)的年龄、年龄形成时间以及臀鳞、背鳍条磨片和耳石磨片对年龄解释的一致性问题进行了探讨。结果表明在取样的 2 5 8尾标本中 ,臀鳞鉴定的年龄在 1～ 2 1龄之间 ,背鳍条磨片为 1～ 2 0龄 ,耳石磨片为 1～ 2 9龄。背鳍条和耳石磨片对年龄的判别能力分别为 98 4 1%和 94 4 4 % ,而臀鳞只有 6 2 30 %。在这三种年龄鉴定的材料中 ,以耳石磨片上的年轮计数最高 ;尤其是 15龄以上的个体 ,耳石磨片年龄计数与臀鳞及背鳍条磨片计数相差可达 5～ 8龄。年轮的形成时间在每年的 4～ 6月。
In this paper, we discussed the age and age of Gymnocyprisselincuoensis, and the consistency of age interpretation between the dorsal fin strips and otolith strips. The results showed that in the 25 samples sampled, the age of the hip scales was between 1 and 21 days, the dorsal fin strips were between 1 and 20 years old, and the otolith discs were between 1 and 29 years old. Dorsal ray strips and otoliths showed 98.41% and 94.44% of their age, respectively, while hip scales were only 62.3%. Among the three materials identified by age, the annual ring count on otolith was the highest, especially in individuals over the age of 15, the difference between otolith age and hips and dorsal rays was 5-8 age. The formation of annual rings in the annual 4 to 6 months.
