摘 要:【目的】开展塔里木河沙雅段叶尔羌高原鳅形态生物学研究。【方法】2008~2010年通过对塔里木河沙雅段叶尔羌高原鳅采样观察,进行有关生物学的测定分析。【结果】发现沙雅段叶尔羌高原鳅形态特征有所不同,群体特征也体现出不同点;尤其是体长和体重,在同一时间段不同河段所表现的关系不一样;沙雅段:体长和体重为Y=0.062 8 X^(2.3272),R^2=0.756 4;体长和空壳重的关系式为:Y=0.047 3 X^(2.4039),R^2=0.814 5,其中n=151;体长和体高线性相关:Y=0.117 7 X+0.713 6,R^2=0.228 6;体长和头长的关系式为:Y=0.270 6 X-0.246 2,R^2=0.692 6;体长和尾柄长关系为:Y=0.202 1 X-0.352 8,R^2=0.382 7;体长和吻长的关系:Y=0.106 X-0.054 8,R^2=0.44;体长与口裂长宽的关系为:Y_长=0.087 3 X-0.035 5,R^2=0.382 5、Y_宽=0.091 4X+0.016 4,R^2=0.432 5;体长与胸、腹、臀长关系为:Y_胸=0.18 X-0.178 7,R^2=0.252 9、Y)腹=-0.04 X+2.247 7,R^2=0.004 9、Y_臀=0.072 4 X+0.546 4,R^2=0.042 6;体长与内外须及颌须的关系式为:Y_内=0.058 2X+0.2,R^2=0.097 3、Y外=0.056 9 X+0.218 6,R^2=0.215 7、Y_(颌须)=0.036 1 X+0.542 1,R^2=0.029;丰满度系数为K=(W/L^3)×100,K=1.400 61。【结论】塔里木河沙雅段叶尔羌高原鳅异速生长不明显,生长较为稳定,小型化严重,捕捞强度过大,资源破坏严重。[Objective]This paper investigated the morphological biology of Triplophysa yarkandensis. [Method]From the year 2008 to 2010,we made the biology measurement and analysis of the samples of Triplophysa yarkandensis from Tarim River.[Result]The results showed that there were differences in the morphological characteristics and population characteristics of Triplophysa(hedinichthys) yarkandensis(day) in Shaya section of Tarim River,particularly in length and weight in the different sections at the same time. Shaya section;Y = 0.0473 X^(2.403 9),R^2 =0.8145.The relationship between length and shell weight;Y = 0. 047 3X^(2.403 9),R^2 = 0.814 5,n = 151.Length is linearly related to height;Y = 0.117 7 X +0.713 6,R^2 = 0.228 6;The relationship between length and head length;Y = 0.270 6 X -0.246 2,R^2 = 0.692 6;The relationship between length and peduncle length;Y = 0.202 1 X-0.352 8,R^2 = 0.382 7;The relationship between length and snout length;Y - 0.106 X-0.054 8,R^2 = 0.44;The relationship between length and mouth width and length of mouth respectively;Y(length)= 0.087 3 X -0.035 5,R^2 = 0.382 5,Y(width)=0. 091 4 X +0.016 4,R^2= 0.432 5;The relationship between length and chest length and abdomen length and rump length respectively;Y(Chest)=0.18X-0.178 7,R^2 = 0.252 9,Y(abdominal)= - 0.04 X + 2.247 7,R^2 = 0.004 9,Y(rump)= 0.072 4 X +0.546 4,R^2 =0.042 6;The relationship between the inside beard length and the outside beard length and whiskers on the jaw length;Y(in)= 0.0582X +0.2,R^2 - 0.097 3,Y (outside)= 0.056 9 X +0.218 6,R^2= 0.215 7,Y_((jaw)) = 0.036 1 X + 0.542 1,R^2 = 0.029;fullness coefficient K =(W/L^3)×100,K = 1.4006 1;[Conclusion]The allometric growth of Triplophysa (hedinichthys) yarkandensis(day) in Shaya Section of Tarim River is not obvious but stable.The fishing is small and dredging is excessive,and the resource is severely damaged.
