对湖北省阳新县网湖所采得的862尾似刺鳊鮈的年龄与生长的研究表明,其年轮特征主要为切割型和碎裂型。其体长与鳞径呈直线相关:L=5.6784+4.3056R;体长与体重呈幂函数的增长关系:W=2.8026×10~(-2)L~(2.8754)。应用Van Bertalanffy生长方程拟合该鱼的一般生长规律,其生长参数为:L_∞=25.0143cm,W_∞=277.8876g,K=0.4668,t_0=-1.3886,拐点年龄t_i=1龄,拐点体长L_i=16.42cm,拐点体重W_i=82.82g。
The research on the age and growth of 862 tail-like stinging catfish collected from Wanghu Lake, Yangxin County, Hubei Province shows that the annual ring characteristics are mainly cut type and fragmentation type. The body length is linearly correlated with the diameter of the scales: L = 5.6784 + 4.3056R; The relationship between body length and body weight is a power function: W = 2.8026 × 10 -2 -2.8754. Van Bertalanffy growth equation was used to fit the general rule of growth of the fish. The growth parameters were as follows: L_∞ = 25.0143cm, W_∞ = 277.8876g, K = 0.4668, t_0 = -1.3886, inflection age t_i = L_i = 16.42cm, inflection weight W_i = 82.82g.
