摘　　要：用黄海鲬鱼的耳石和鳞片相对照,对其年龄进行了鉴定。分析了不同年龄组的体长和体重分布。分别计算出雌雄各龄组的体长与体重、鳞长与体长的关系式,并用幂函数关系和直线回归方程进行计算和比较,鲬鱼生长适合于V.Bertalanffy生长方程。还分析了其阶段生长情况。Altogether 742 specimens of flathead fish were studied byexamining the otoliths and scales for age determination. The specimens were collectedfrom a small harbour of Qingdao from February to early May in 1966. Both theotoliths and scales were identical in age determination. Growth stuies were made bymeans of scales method. Two commonly formulae W=bL^(?) and W=a+ bL were appied to compute thelength relationship of flat head fish. The following expressions were derived:W=0.248×10^(-?)LW=-513 .864+2.583L^(?) These formulas were also used to calculate the relationship between body lengthand scale length of flat head fish. We obtain:L=a+bR=71. 4992+80. 881RL=qR^(b)=132. 9148R^(0.7?)where W, L, and R respectively represent body weight(without gut and gonads),standard length and scale length. The results indicate tha both formulae of powerseries and linear are suitable in such calculations. But the formula of power seriesseems to be better for calculating length-weight relationship and the formula of linearseems to be better for back calculation of body length, especially when dealing withjuvenile specimens. The growth of the flat head fish in Yellow Sea corresponds to von bertalanffy'sgrowth equation. The results are as follows:W=1147. 36[1-e^(0.--?01)(?+0.441)]^(?.2)L_t=459. 1696[1--e^(0.?)(t+0.8715)]where W;is body woigth (excluding gut gooads) in grams at the age of t, and L; isstandard length in mm at the age of t. The growth rate was calculated in relation toage of this fish.
