摘要
2010年10月测定了陆浑水库渔获野生条体长、全长、体重、年龄、性别和食物组成等指标,对该水体中条的生长和食性进行了初步研究,得出以下主要结论:渔获条由0^+-2^+龄共3个年龄组组成;体长与体重关系式:W=0.0128L^(3.0279)(R^2=0.9465,n=85);主要摄食枝角类、硅藻、蓝藻、绿藻等浮游生物和有机碎屑。通过分析其生长状况和食性,并综合考虑,建议其适宜起捕年龄为1龄。
The growth and feeding habits of Hemiculter leucisculus in Luhun Reservoir was studied by record of length, weight, age, sex and food composition,etc in October 2010. The major findings were as follows: The catch was composed of age groups from 0^+to 2^+; The relation of body length with weight was: W = 0.0128 L^(3.0279)(R^2= 0.9465,n =85); Its diet mainly included cladocera, organic detritus, phytoplankton, etc. By analyzing the growth and feeding habits, the minimum harvested age was recommended at 1.
