The biological characteristics of wild Leptobotia taeniops in Tongling section of the Yangtze River,such as morphological feature,the relationship of body length and weight,fatness,feeding habits,reproduction,etc,were observed by means of biological surve%按常规生物学方法,对长江铜陵段紫薄鳅(Leptobotia taeniops)的形态特征、体长与体重关系、肥满度、食性、繁殖等个体生物学特征进行了初步研究。结果表明,所取样本体长范围为6.81~12.40cm,体重范围为7.00~36.24g;体长与体重呈显著的幂函数关系:W=0.0348L2.7480(r=0.9090);为偏动物食性的杂食性鱼类。以体长8.00~10.00cm组的肥满度为高,雄性的Fulton肥满度随体长的逐渐增加而降低。性成熟年龄在1+~2+龄,4~7月份产卵繁殖,卵为半漂浮性。种群
