摘要
为了研究黄河鲤(Cyprinus carpio haematopterus)在池养条件下的生长特性,探索黄河鲤的生长规律,于2017年5—10月开展了养殖试验,获得其成活率和饲料系数,并通过测量其体长、体质量和体高,对黄河鲤在池养条件下进行生长特性的分析。结果表明:经过约5个月的养殖,黄河鲤成活率92.6%,饲料系数1.38,体长、体质量和体高的平均值分别为21.13 cm,689.21 g和7.73 cm。相应的变异系数范围分别为10.88%~15.53%,9.15%~46.44%和13.82%~22.04%,肥满度在2.84~7.31之间变动。体长(LS)与全长(LT)之间存在线性回归关系:LT=1.721LS+0.4517(R2=0.9998),体长与体质量(W)的回归方程为:W=0.0174L3.2946(R2=0.9725)。拟合出von Bertallanffy生长方程:LSt=29.354(1-1.082e-0.399t)3,Wt=1790.916(1-1.688e-0.547t)3,LHt=9.352(1-1.688e-0.54t)3,投入产出比为1:1.19。黄河鲤在池养条件下生长速度较快,且经济效益良好,为皖北黄河鲤规模化养殖提供理论参考。
To study the growth characteristics of Cyprinus carpio haematopterus under pond culture condition and explore their growth rules,breeding experiments were carried out from May to October in 2017,and the survival rate and feed coefficient were obtained.By measuring the body length,body mass and body height,the growth characteristics of the carp under pond culture condition were analyzed.The results showed that after about 5-month breeding,the survival rate of the carp was 92.6%,the feed coefficient was 1.38,and the average body length,body mass and body height was 21.13 cm,689.21 g and 7.73 cm,respectively.The corresponding coefficient of variation ranged from 10.88%to 15.53%,9.15%to 46.44%,and 13.82%to 22.04%,respectively.Additionally,the relative fatness ranged from 2.84 to 7.31.There was a linear regression relationship between body length(LS)and total length(LT):LT=1.721 LS+0.4517(R2=0.9998),and the regression equation of body length and body mass(W)was:W=0.0174 L3.2946(R2=0.9725).The growth equation of von Bertallanffy was fitted:LSt=29.354(1-1.082 e-0.399 t)3,Wt=1790.916(1-1.688 e-0.547 t)3,LHt=9.352(1-1.688 e-0.54 t)3,and the input-output ratio was 1:1.19.In conclusion,the growth rate of Cyprinus carpio haematopterus under pond culture condition is faster and the economic benefit is well,and the study provides a theoretical reference for the large-scale culture of carp in the north of Anhui.
