以鳞片鉴定年龄,分析了黑屋湾水库鲢,鳙鱼体长与鳞长的直线相关式,体长与体重的幂函数关系式。应用的生长方程计算出各参数值。并指出以生长拐点年龄2.8龄作为合理捕捞生物学指标和养殖周期是提高该库鱼产量的重要因素之一。
The scale was used to identify the age, and the linear correlation between body length and scale length of silver carp and bighead carp in black-shelled-water Bay reservoirs was analyzed. The power function relationship between body length and body weight was analyzed. The growth equation is used to calculate the value of each parameter. It is also pointed out that taking growth age of 2.8 years as the index of reasonable fishing and breeding cycle is one of the important factors to improve the yield of this fish.
