闽南-台湾浅滩渔场大头狗母鱼捕捞群体由0—Ⅵ龄组七个世代组成,主要为Ⅰ龄组(41.04%)和Ⅱ龄组(31.97%).生长分为增长、稳定和衰老三个阶段.von Bertalanffy 叉长生长方程为 L=567.72 ×[1-e~(-0·1009(t+1·4200))],纯体重生长方程为 W=785.08×[1-e~(-0·1743(t+0·7417))~3.种群存活率为0.2174,年总死亡年为0.7826,瞬时总死亡率为1.5260,瞬时自然死亡率和瞬时捕捞死亡率分别为0.3071和1.2189.最适捕捞叉长、纯体重和总体重分别为300.56mm、268.87g 和318.19g;最佳最小捕捞叉长、纯体重和总体重分别为187.91mm、73.43g和81.58g.
The fishing population of the big-headed pomfret in Minnan-Taiwan Shoal fishing ground consisted of seven generations of 0-Ⅵ age groups, which were mainly composed of 41.04% in age group Ⅰ and 31.97% in Ⅱ-age group. The growth was divided into three stages: growth, stabilization and senescence The growth equation of von Bertalanffy was L = 567.72 × [1-e ~ (-0 · 1009 (t + 1 · 4200))], and the growth equation of pure weight was W = 785.08 × [1-e ~ · 1743 (t +0 · 7417)) ~ 3. The survival rate of the population was 0.2174, the annual total mortality was 0.7826, the instantaneous total mortality was 1.5260, the instantaneous natural mortality and instantaneous fishing mortality were 0.3071 and 1.2189 respectively. The length of the fishing forks, pure body weight and total body weight were 300.56mm, 268.87g and 318.19g, respectively. The optimum minimum length of fishing fork, pure body weight and total body weight were 187.91mm, 73.43g and 81.58g respectively.
