摘要
对1998—2000年在黄河宁夏永宁县望洪段采集的679尾棒花鮈进行了生物学方面的初步研究。结果表明,宁夏黄河棒花鮈的鳞片年轮形成时间集中在5～7月;通过鳞片鉴定年龄,确定种群由1～4龄主组成。通过分析棒花鮈的体长、体重分布、年龄组成体长和体重的实测生长,得到了体长与体重的关系式W=2.74×10^(-2)L^(2.97),并对其食性、繁殖力进行了初步研究,还对棒花鮈的保护和合理利用提出了一些建议。
It was a preliminary biological research on Gobia riraloides Nichols which was collected from the Wanghong section of the Yellow River in Yongning, Ningxia from 1998 to 2002. The results showed that the forming of its age circle was formed during May to July, and that the colony was composed of 1 - 4 age. The length and the weight distribution, the age composion and the practical data of length and weight about this fish were analyzed, and a equation about the length and weight (W = 2.74×10-2L2.97) was given, In the end, some proposals were put forward about the resources protection and the reasonable utilization of Gobio riraloides Nichols.
