| 摘 要： | 研究乌江思林库区泉水鱼的年龄和生长特性,为其资源的保护提供基础数据资料。2014年在乌江思林库区大乌江、文家店采集泉水鱼246尾,研究年龄组成与生长特性。泉水鱼体长74.00～214.00mm、体重7.40～277.70g,构成年龄为1～3龄、2龄个体为主(占62.69%)。体长与体重的关系式为W=2×10-5 L3.086(r2=0.973),表明泉水鱼属于匀速增长类型。Von Bertalanffy生长方程为Lt=246.231-e-0.77(t-0.54)]和Wt=479.411-e-0.77(t-0.54)]3.086,渐进体长246.23mm,生长系数0.77,理论生长起点年龄为0.54龄。体重生长的拐点年龄为2.003龄,对应的体长和体重分别为166.27mm和142.71g。为保护泉水鱼资源,捕捞规格应该高于拐点年龄时的规格。
