摘　　要：为探究北方池塘养殖匙吻鲟(Polyodon spathula)的生长特性,于2024年6月1日至2024年9月30日,对在池塘人工养殖条件下1+龄匙吻鲟进行随机采样及生物学测定分析。结果显示,至实验结束时,匙吻鲟的平均体长69.6 cm,平均体质量1830 g。体质量与体长呈幂函数关系,方程为W=0.0815L^(2.35),R^(2)=0.9861。其中幂函数指数小于3,表明1+龄匙吻鲟在北方池塘养殖条件下呈异速生长。To investigate the growth characteristics of Polyodon spathula farmed in northern pond,the growth and morphology parameters of this specie(about 1 year old)were measured and analyzed.The results showed that by the end of the experiment,the average body length and the average body weight was 69.6 cm and 1830 g.The power function equation of body weight and body length was W=0.0815 L^(2.35),R^(2)=0.9861,and the power function index is less than 3,which indicated that the growth of Polyodon spathula was allometric under pond culture.
