摘要: 为探究中华绒螯蟹幼蟹蜕壳期间池塘水环境的变化特征,于2018年5月7日至10月13日,对上海松江泖港地区幼蟹生态养殖池塘和水源进行水质监测.结果表明,大眼幼体经160 d养殖,蜕壳11次成长为幼蟹,T均值为27.0±2.9℃,总有效积温为3085.3℃·d;随蜕壳次数增加,有效积温增长趋势贴近指数函数y=42.166e0.2644x,R2=0.9629;累计有效积温增长趋势贴近二次函数y=33.059x2-98.244x+160.05,R2=0.9992.幼蟹池溶解氧(DO)在养殖前期优于水源,NH4+-N、NO-2-N、NO3--N总体优于水源,PO43--P在高温季节优于水源,CODMn在整个养殖阶段均较水源差.除TN、TP、CODMn有不同程度超标外,幼蟹池和水源其它水质因子基本符合渔业水质标准和地表水环境质量标准的Ⅲ级标准.Abstract: The present study investigated water parameters of juvenile mitten crab (Eriocheir sinensis) farming ponds at the Songjiang District, Shanghai during every molting period from May 7 to October 13, 2018. Results show that the E.sinensis larva grows up to the juvenile stage after 11 times of molting and 160 days cultivation. In this period, the average temperature was 27.0±2.9℃, and the total effective accumulated temperature was 3085.3℃·d. Along with the increased time of the juvenile E.sinensis molting, the effective accumulated temperature increased exponentially (y=42.166e0.2644x, R2=0.9629), and the increase of cumulative effective accumulated temperature followed a polynomial equation (y=33.059x2-98.244x+160.05, R2=0.9992). The concentration of dissolved oxygen (DO) in the juvenile E.sinensis farming ponds was higher than that of source water at the early stage. Overall, the concentrations of NH4+-N, NO-2-N, and NO3--N of the juvenile E.sinensis farming ponds were lower than that of the source water. The concentration of PO43--P of the juvenile E.sinensis farming ponds was lower than that of source water in the high-temperature season. However, the concentration of CODMn of the juvenile E.sinensis ponds was higher than that of source water during the whole farming cycle. In addition to TN, TP, and CODMn, the water quality index of ponds water and source water are basically met the fishery water quality standards and the third-grade surface water standard.
