摘要:

【目的】研究新疆特克斯河斑重唇鱼形态特征及年龄与生长等生态学特性。【方法】2019~2021年采样观察特克斯河斑重唇鱼,运用经典生物学测量方法鉴定年龄,分析其生长性状。【结果】特克斯河斑重唇鱼,体延长,被细鳞,侧线完全,形态特征不同于其他水系,差异较大,体背色泽灰褐色,有不同的黑色斑点,腹部浅黄泛灰白。斑重唇鱼,体长均值(143.66±57.94) mm,体重均值(64.81±92.10) g,年龄均值(4.08±2.49*);体长与体重拟合关系式为W=5.80×10-6L3.165 3(R2=0.952 1),属于异速生长;体长与体高、头长、吻长、眼间距、尾柄长和尾柄高相关性较高,与体宽和眼径的相关性较低。特克斯河斑重唇鱼(n=120)渐进体长L∞=346.79 mm,k=0.07,W∞=634.97 g,t 0 = - 0.34,ti=12.46。生长方程:Lt = 346.79 (1-e-0.09 (t + 0.34)),Wt = 634.97 (1-e-0.09 (t + 0.34))3.165 3【结论】特克斯河斑重唇鱼形态不同于其他水系,高原冷水鱼类,属异速生长,适应性欠佳,拐点年龄大,生长缓慢,生长性状不稳定。

Abstract:

【Objective】 To explore the morphological characteristics, age, growth and other ecological characteristics of spotted Diptychus maculates in Turks River.【Methods】 From 2019 to 2021, through the sampling and observation of the Turks river spotted Diptychus maculates., classical biological measurement methods were used to identify the age and analyze its growth characteristics.【Results】 The body of Turks Rriver spotted double-lipped fish was elongated, with fine scales, and the lateral line was complete.The morphological characteristics were different from other water systems.The color of the back was gray-brown, with different black spots, and the abdomen was light yellow and grayish-white.The average body length was (143.66±57.94) mm, the average weight was (64.81±92.10) g, and the average age (4.08±2.49*); The fitting relationship between body length and weight was W =5.80×10-6L3.165,3(R2=0.952,1), which belonged to allometric growth; Body length was highly correlated with body height, head length, snout length, eye distance, caudal stalk length, and caudal stalk height, but had a lower correlation with body width and.The progressive body length (n=120) was L∞=346.79 mm, k=0.09, W∞=634.97 g, t 0 = - 0.34, ti=12.46.Growth equation of length and weight: Lt = 346.79 (1-e-0.09 (t + 0.34)),Wt = 634.97 (1-e-0.09 (t + 0.34))3.165,3.【Conclusion】 The morphology of Turks river spotted Diptychus maculates is different from other water systems.It is a plateau cold-water fish with allometric growth, poor adaptability, old inflection point, slow growth, and unstable growth characteristics.

Key words: Turks River; Diptychus maculates; morphological character
