报道了武湖翘嘴红鱼白的年龄生长特点。其渔获物中 2 + 和 3+ 龄个体占 5 7 1 % ,体长以 30 0～ 6 0 0mm为主 ,体长与鳞长之间呈直线相关 :L =6 .1 81 4 +90 .4837R ,体重与体长呈指数函数相关 :W =2 .0 45×1 0 -6L3 .2 585,3+ 龄以前生长最快 ,生长指标高 ,体长和体重的相对增长率大 ,其生长规律符合VonBertalanffy方程 :L1=1 4 0 4.9(1 -e-0 .10 (t+ 0 .71) ) ,W1=3.6 2 9× 1 4(1 -e-0 .10 (t+ 0 .71) ) 3 .2 585,捕捞 3龄以上个体较为合理
Reported the Wuhu Cichlips auratus white age growth characteristics. The catches of 2 + and 3+ individuals accounted for 57.1% of the total body length, with a body length of 30 0 ~ 600 mm. There was a linear correlation between body length and scale length: L = 6.181 4 +90 .4837R, body weight and body length were exponential function related: W = 2.05 × 10-6L3 .2 585,3 + age before the fastest growth, high growth index, the relative growth rate of body length and body weight, its The growth law follows the Von Bertalanffy equation: L1 = 1 4 0 4.9 (1 -e-0 .10 (t + 0 .71)), W1 = 3.6 2 9 × 1 4 (1 -e-0 .10 (t + 0 .71) ) 3.52 585, fishing more than 3 individuals more reasonable
