摘要
本文根据1960——1963年在浙江近海渔场收集的带鱼耳石资料进行年龄和生长的研究。本海区带鱼耳石上轮纹形成的周期为一年,肛长 L 与总重 W 的关系式为:夏汛(5、6月)W=3.083×10^(-s)L^(2.8568);冬汛(11、12月)W=3.025×10^(-s)L^(2.8806)。带鱼肛长与耳石半径长 R 的关系式为:L=-41.54+77.23R。本海区带鱼的生长可用 Von Bert-allanffy 生长方程描述。极限体长 L_∞=559.1毫米,极限体重 W_∞=2176克。带鱼体重生长曲线的拐点位于 t=3.14令处。本海区带鱼一般生长型与日本纪伊水道的带鱼比较接近,而与黄、渤海区的带鱼相差较大。
This is an age-growth study of Trichiurus lepturus based on otolithes collected from Zhejiang off-shore fishing ground.The formation of otolith rim of this fish is of yearly character. Relationship between anal length and total weight: Summer fishing seasons(May and June) W=3.083×10^(-5)L^(2.8568) Winter fishing season(November and December) W=3.025×10^(-5)L^(2.8806) Relationship between anal length and the radius of otolith L=-41.54+77.23R The growth of the fish can be expressed by Bon Bertallanffy's fish growth equation. limit length L_∞=559.1mm limit weight W_∞=2176g k=0.274 t_0=-0.87 The point of flextion is at t=3.14 year-class. The growth pattern of the fish in this sea area is much the same with that in Kihan Strait,Japan and quite different with that in Bohai Sea and Huanghai Sea of China.
