2010年7月至2011年12月,在塔里木河阿拉尔段采集叶尔羌高原鳅Triplophysa (Hedinichthys) yar-kandensis (Day)940尾(除性别未辨个体外)用于繁殖生物学研究。种群雌雄比为0.85︰1,最小性成熟,雌性个体体长为8.2 cm,体重为7.4 g,年龄为3龄;雄性个体体长为6.5 cm,体重为3.4 g,年龄为2龄。叶尔羌高原鳅卵径分布呈单峰形,推测应属于同步产卵类型。计算了88尾Ⅳ-Ⅴ期雌鱼的怀卵量,其体长范围30-195 mm,体重范围3.59-114.04 g,绝对繁殖力为1101-56320(9944±5487)粒,相对繁殖力为824-1140(982±158);塔里木河阿拉尔段叶尔羌高原鳅种群繁殖力(Fp)为403.46万粒。

Triplophysa (Hedinichthys) yarkandensis (Day) was collected in Alar Section of Tarim River from July 2010 to December 2011 and 940 breedings were used for reproductive biology research. The female and male ratio was 0.85︰1. Standard length, weight and age of the females at a minimum maturity were 8.2 mm, 7.4 g and 3 years old, and those of the males were 6.5 mm, 3.4 g and 2 years old, respectively. Their egg diameters presented unimodal distribution, indi-cated that they belonged to one-time spawning. The fecundity of 88 females sangles at Ⅳ-ⅤStage was calculated, including standard length (L) ranging from 30 to 195 mm, weight (W) ranging from 3.59 to 114.04 g, absolute fecundity ranging from 1101 to 56320 (9944±5487), the relative fecundity ranging from 824 to 1140 (982±158) and the fecundity population (Fp) of 4034600.
