摘要:
2015年对浙北地区温室中华鳖、外塘中华鳖、加州鲈、乌鳢、翘嘴红鲌5个淡水养殖品种在1个养殖周期内的养殖水及周边外河水中碳、氮含量进行调查测定,分析不同养殖品种及周边外河水体中的碳氮比(简称C/N)水平。结果显示,各养殖品种养殖水体中总有机碳(简称TOC)含量随养殖时间的延长而增加,总氮(简称TN)含量随养殖时间的延长先增加后减少,在8月达到最大值;而水体中C/N则随养殖时间先减小后增加,且在8月达到最小值;比较养殖水体和周边外河水中的C/N,结果显示,温室中华鳖养殖池水中C/N最低为0.65;翘嘴红鲌养殖池水中最高为559,各养殖品种间差异显著(P<0.05),但作为养殖水源的周边各外河水间无显著性差异。此外,相关性分析显示,高 C/N 的养殖水体水质显著优于(P<0.05)低C/N的养殖水体水质,说明养殖后期适当添加额外碳源,提高养殖水体C/N,可能是改善养殖环境的有效途径。
