对兴凯湖翘嘴红鲌Erythroculter ilishaeform is(B leeker)的生长式型进行了研究,经统计分析表明:翘嘴红鲌的体长与鳞径的关系为L=0.7960×10-3R1.9060(r=0.9729);体长与体重的关系为W=8.9047×10-3L3.0427(r=0.9153),属等速生长类型;用Von Bertalanffy生长方程拟合了兴凯湖翘嘴红鲌的生长,其渐近体长和渐近体重分别为98.05 cm和10.21 kg,拐点年龄出现在10.42龄,拐点体长为65.81 cm,体重为3.03 kg,与长江水系翘嘴红鲌的生长式型不同。
The growth pattern of Erythroculter ilishaeform is (B leeker) in Xingkai Lake was studied. The statistical analysis showed that the relation between the body length and the diameter of the scallop is L = 0.7960 × 10-3R1.9060 (r = 0.9729). The relationship between body length and body weight was W = 8.9047 × 10-3L3.0427 (r = 0.9153), which belonged to an isokinetic growth type. The growth equation of Von Bertalanffy Growth, the asymptotic body length and asymptotic body weight were 98.05 cm and 10.21 kg respectively, the age of inflection point was 10.42 and the inflection body length was 65.81 cm and weight was 3.03 kg. .
