中文摘要:对采自江西省袁河的68(鱼骨)个体繁殖力及其与生物学指标的关系进行了研究。结果表明,体长在11.028.5 cm、体重在27.3418 g的个体,绝对繁殖力(F)54047 477.06粒,相对体长繁殖力(FL)和相对体重繁殖力(FW)分别为31.401683.96/cm5.82249.17/gFFL与年龄、体长、体重、体长×体重、净体重、卵巢重和成熟系数显著相关,FW与卵巢重和成熟系数显著相关;个体绝对生殖力与各指标逐步回归方程为:F=20062.53+604.307Wg+244.982W1365.731L–134.223W0–4183.265K (R2=0.935n=68),经卵径分布频数图初步推断,袁河(鱼骨)为一次产卵鱼。
英文摘要:The correlations between fecundity and biological indices were studied in 68 Hemibarbus maculates specimens which were collected from Yuanhe River (Jiangxi Province, China) during March 2009 and June 2011. In specimens with the body length of 11.028.5 cm and body weight of 27.3418 g, the individual absolute fecundity (F) ranged from 540 to 47 477.06 eggs, and the individual relative fecundities of body length (FL) and body weight (FW) were 31.40 to 1683.96 eggs/cm and 5.82 to 249.17 eggs/g, respectively. Both F and FL showed significant correlations with age, body length, body weight, net weight, body length×body weight, ovary weight and coefficient of maturity (P < 0.05), and FW was also significantly related with coefficient of maturity and GSI. Thus, based on the frequency charts of spawn diameter, H. maculate was preliminary deduced to spawn once a year. The multiple stepwise regression equation was F=20 062.53 + 604.307Wg+244.982W1365.731L–134.223W0–4183.265K(R2=0.935n=68) between the individual absolute fecundity F and biological indices.
