Preliminary data on growth and reproduction parameters of Cobitis simplicispina from Darýözü Creek in the Kizilimak basin in Kirşehir-Turkey were presented. The age of the specimens collected during a period between March and June 2002, ranged from 1+ to 4+. The observed maximum total length of males is 91.8 mm, and 97 mm for females. The von Bertalanffy equation for male and female specimens was found to be Lt=93.01(1-exp(-0.408(t+0.821))) and Lt=94.42(1-exp(-0.488(t+0.458))), respectively. The length-weight relationship was expressed as log W= 3.009x SL -5.171 when all specimens were taken into account. The range of absolute fecundity extended from 320 to 2141 eggs and the diameter of ripe eggs varied between 1.00 and 1.25 mm. The gonadosomatic index suggested that spawning took place in April.
本文给出了土耳其基尔希尔省克孜勒马克河流域达里约祖溪中华纹鳅生长和繁殖参数的初步数据。2002年3月至6月期间采集的样本年龄范围为1+至4+。观察到雄性的最大全长为91.8毫米,雌性为97毫米。雄性和雌性样本的冯·贝塔朗菲方程分别为Lt=93.01(1-exp(-0.408(t+0.821)))和Lt=94.42(1-exp(-0.488(t+0.458)))。当考虑所有样本时,体长-体重关系表示为log W = 3.009×SL - 5.171。绝对繁殖力范围为320至2141粒卵,成熟卵直径在1.00至1.25毫米之间。性腺指数表明产卵发生在4月。
