摘  要:
本文以椎骨作为鉴定年龄的材料,研究了台湾海峡及其邻近海区扁舵鲣的生长与死亡的特性。其叉长与椎体半径的关系式为L=3.5517+7.6183R,叉长与纯体重(W)和总体重(w′)的关系式分别为W=2.505×10~(-6)L~(3.3193)和W′=1.658×10~(-(?))L~(3.4065)。生长参数L_∞=484.44mm,W_∞=2050.76g,K=0.5109,t_0=-0.3598,体重生长拐点在1.4461龄。瞬时总死亡率、瞬时自然死亡率和瞬时捕捞死亡率分别为1.1368、0.9040和0.2328。开发率为0.2048,属轻度开发的鱼类资源。

摘  要:
The study on the growth and mortality of Auxis thazard in the Taiwan Strait and its adjacent sea, mainly based on the vertebra material of the species to determine age. The relation formulae between fork and vertebra radius were: L= 3.5517+7.6183R, the longth-weight relationship formulas are calculated to be and, where W and W' represent net body weight (g) and total body weight (g) respectively. The parameters of fork length and net body weight growth equation are: L_∞=484.44mm, W_∞=2050.76g, k=0.5109, t=-0.3598. The turning point on body weight growth curve of the species was stuated at t= 1.4461 years of age. The instantaneous rate of total mortality is 1.1368, and the instantaneous natural and fishing mortality rates are 0.9040 and 0.2328 respectively. The rate of exploitation is 0.2048, the species be- long to the fish resource of lower exploitation.
