中文摘要:
      1.体长与椎体之间的关系呈正紧密直线相关。其关系式为:L=7.046R+49.590 r=0.938 2.用第一个椎骨的椎体作为观察和测定年轮的材料。年轮在透射光线下界于透明带和不透明带之间。其特征可分为以下三种类型:(1)单带型,(2)双带型,(3)多带型。 3.根据椎体边缘相对生长量的周年测定结果,证实该年轮系一年形成一次,时间为12月份至翌年5、6月份,主要的形成期是4~6月份。 4. 绿鳍马面鲀各龄鱼的平均体长和体重为:Ⅰ龄鱼:119.5毫米,44.5克;Ⅱ龄鱼:159.9毫米,70.9克;Ⅲ龄鱼:194.8毫米,136.9克;Ⅳ龄鱼:215.2毫米,190.8克;Ⅴ龄鱼;229.2毫米,231.3克;Ⅵ龄鱼:245.9毫米,283.5克。 5.体长和体重之间呈指数函数关系。关系式:L=41.324·W0.315 6.从现有的标样观察和分析,绿鳍马面鲀的最高寿命为X龄。年龄组成比较简单,以Ⅲ、Ⅳ龄组占优势,Ⅵ龄以上各组数量极少。
英文摘要:
      The materials were collected in January to June, September to November, 1975; inDecember, 1977; and also in January to August, 1978. Altogether 1,400 samples werecollected by trawling and ranged 26°30'N~34°N and west of 125°30'E. The results are as follows: 1. The relationship between body length and centrum radius is shown by the followinglinear correlation: L = 7.046R + 49.590 r= 0. 938 (FM) L = 7.241R + 46.016 r=0.949 (F) L = 6.555R + 60. 666 R= 0. 906 (M)Where L = body lengh R = centrun radius r = relative coefficient 2. The centrum of the atlas was taken as a material for examining and measuring theannual ring. The annual ring was found between the opague zons and translucent zoneunder transmitted light. The characteristics may be divided into three types. (1) Mono-belt type. (2) Bi--belt type. (3) Poly-belt type. 3. According to the year round measurement of the marginal increment of the cen-trum, it proves that the ring forms once a year. The time of formation is from Decemberto June, mainly between April and June. 4. The average body length and body weight of filefish in each age group are asfollows: Ⅰ age: 119. 5 mm and 44. 5 g, Ⅱ age: 159. 9 mm and 70. 9 g, Ⅲ age: 194. 8 mm and 136. 9g, Ⅳ age: 215. 2 mm and 190. 8g, Ⅴ age. 229. 2 mm and 231. 3 g, Ⅵ age: 245. 9 mm and 283. 5g, Ⅶ age: 266. 3 mm and 390. 0g, Ⅷ age: 280.0 mm and 447.5g,Ⅸ age: 290.0 mm and 547. 5g, respectively.The length of first maturing female is at 158. 2 mm, and the male 162. 6 mm. 5. The length-weight relationship may be predicated by the equation of exponentialtunction. L = 41. 324W 0: 315Where L = body Length W = body Weight 6. Through the observations and analyses of the samples, the maximum life span ofthe species is ebout ten years, the age composition is comparatively simple, age groupe Ⅲand IY predominate in the population, and individuals older then six years occur only in alimited quantity.
