对藏北高原色林错湖泊中色林错裸鲤 (Gymnocyprisselincuoensis)的生长方程、生长拐点以及生长指标等生长特征进行了分析。结果表明vonBertalanffy生长方程、Gompertz方程和三次多项式方程都可以反映色林错裸鲤的生长过程 ,但Gompertz方程能够很好地描述 12龄之前的生长特征 ,而vonBertalanffy生长方程更适合描述 18龄以后的生长特征。这种情况反映了色林错裸鲤具有洄游性鱼类更换生活环境的生活史特征。雄性体长的vonBertalanffy生长方程为 :Lt =4 84 190 6 [1-e-0 0 683 9(t-0 0 60 2 8) ],雌性为Lt =4 85 32 85 [1-e-0 0 710 (t-0 5679) ]。体长和体重关系为W =0 0 0 0 2 3L2 53 0 3 (♂ )和W =0 0 0 0 4 6L2 40 72 (♀ )。生长拐点为 12 9龄 (♀ )和 14 2龄 (♂ )。与其它裂腹鱼类相比 ,色林错裸鲤的生长过程尤为缓慢 ,这与其生存的环境条件更为恶劣直接相关。
The growth characteristics, growth inflection point and growth index of gymnocyprisselincuoensis in the Selinakse Lake in northern Tibet Plateau were analyzed. The results show that von Bertalanffy growth equation, Gompertz equation and cubic polynomial equation can reflect the growth process of Solenopsis carinosae, but Gompertz equation can well describe the growth characteristics before 12 years old, while von Bertalanffy growth equation is more suitable for describing Growth characteristics. This situation reflects the history of the life cycle of the migratory fish species in the forest. Male body length vonBertalanffy growth equation is: Lt = 4 84 190 6 [1-e-0 0 683 9 (t-0 0 60 2 8)], female Lt = 4 85 32 85 [1-e-0 0 710 (t-0 5679)]. Body length and body weight were W = 0 0 0 0 2 3L2 53 0 3 (♂) and W = 0 0 0 0 4 6L2 40 72 (♀). The turning point of growth was 12 9 (♀) and 14 2 (♂). Compared with other Sulzer fishes, the growth of Solenopsis carinosae is particularly slow, which is directly related to the worse environmental conditions of its survival.
