对湖泊网围养殖的7种鱼类作了早期生长发育规律的探讨及研究,认为一龄鱼种其体长、体重随月龄的增长几呈直线上升。依体长生长直线,将7种鱼归为2类;依体重生长直线,则可将其归为3类.描述体重、体长关系的鱼类生长指数 b 值介于2.8～4.0间.应根据鱼的不同种类、不同年龄,使用不同的 b值计算其丰满度.计算了7种一龄鱼的体长月平均增长指数及体重月平均增重指数,分别为:鲤2.93,275.14;鲫1.92,229.89;鳊1.41,231.05;草2.59,236.53;奥尼2.69,462.94;鲢2.14,145.11;鳙2.33,152.41.
The study on the law of early growth and development of seven species of fishes cultured around the lake shows that the body length and body weight of first-year fish species increased linearly with the increase of age. According to the length of the growth of a straight line, the seven kinds of fish are grouped into two categories; according to the weight of the growth of a straight line, it can be classified as 3. Body weight, body length relationship of fish growth index b value between 2.8 to 4.0 should be based on The different types of fish, different ages, the use of different b value calculation of its fullness.Calculated the 7 kinds of first-year fish body length average growth index and body weight average monthly gain index, respectively: carp 2.93,275.14; crucian carp 1.92 , 229.89; 鳊 1.41, 231.05; Grass 2.59, 236.53; Onyx 2.69, 462.94; Silver carp 2.14, 145.11; 鳙 2.33, 152.41.
