中文摘要：采用胸鳍部位的鳞片作为研究湛江沿海勒氏笛鲷的年龄鉴定材料。鳞长（Ｒ）和体长（Ｌ）的关系为Ｌ＝１９．８１５９＋６３．３６９６Ｒ。用灰色动态生长模型，一般ＶＢＧＦ和特殊ＶＢＧＦ都可表达体长、体重和年龄的关系，生长模型分别为Ｌｔ＋１＝４７４．０－３４２．６ｅ－０．２３６ｔ，Ｗｔ＋１＝－１５９４．４＋１６５６．２ｅ０．１２３ｔ，Ｌｔ＝４４１．８［１－ｅ－０．３１９１（ｔ＋０．９５５２）］１０．６４３，Ｗｔ＝２５３９．７［１－ｅ－０．３１９１（ｔ＋０．９５５２）］３．０６５１０．６４３，Ｌｔ＝４６９．８［１－ｅ－０．２４２５（ｔ＋０．３７６２）］，Ｗｔ＝３３６６．６［１－ｅ－０．２４２５（ｔ＋０．３７６２）］３。根据ｒ－选择和ｋ－选择的典型特征及渐近体长（Ｌ∞）、渐近体重（Ｗ∞）、生长系数（Ｋ）、瞬时自然死亡率（Ｍ）、初次生殖年龄（Ｔｍ）、最大年龄（Ｔｍａｘ）和种群繁殖力（ＰＦ）等７个生态学参数值，可以判断勒氏笛鲷偏向ｒ－选择。应用平衡产量模式计算改变瞬时捕捞死亡率（Ｆ）和渔业补充年龄（ｔｃ）时的产量变化，同样证实勒氏笛鲷偏向ｒ－选择。作为渔业管理对策，勒氏笛鲷的捕捞年龄在３龄以上，捕捞强度不超过１．５。在人工饲养条?

外文摘要：The scale under pectoral fin is selected for the age determination material of Lutianus russelli in the littoral waters of Zhangjiang. The relationship between the length of the scale(R) and the body length(L.mm) is L=19.815 9+63.369 6R(r=0.991 6). The relationship between body length or body weight (W.g) and age can be described by the grey dynamic growth model(GDGM) and Von Bertalanffy growth equation(VBGF). The growth models are as follows: L t+1 =474.0-342.6e -0.236t ,W t+1 =-1 594.4+1 656.2e -0.123t , L t=441.8[1-e -0.319 1(t+0.955 2) ] 10.643 ,W t=2 539.7[1-e -0.319 1(t+0.955 2) ] 3.065 10.643 , L t=469.8[1-e -0.242 5(t+0.376 2) ],W t=3 366.6[1-e -0.242 5(t+0.376 2) ] 3. According to the typical characteristics of r and k selection and the given values of seven ecological parameters,namely,asymptotic body length(L),asymptotic body weight(W),growth coefficient(k),instantaneous natural mortality(M),primary reproductive age (T m),maximum age (T max ) and population fecundity(PF),it is concluded that the life history pattern of L.russelli tends to r selection. Equilibrium yield model is applied to calculate the fish yield. When the instaneous fishing mortality(F) is changed,the yield curve has a weaker peak at relatively low value of F, and beyond the value of F, the yield inreases to a maximum value at t c=1.5years and then decreases greatly with raising t c. Analysis of yield curves also demonstrates that the life history pattern inclines to r selection. As a strategy of fishery management,the harvesting age can be decided above three years of age ,the strength of fishing can not be more than 1.5. Under the condition of artificial raise,the cycle of cultivation can be determined at two to three years of age.
