水产养殖户如何正确测定水体的溶解氧,溶氧监测对淡水养殖和海水养殖重要性简述

 

溶氧管理是池塘养殖水质管理的一个重要内容,是一项以动物的溶氧需求为基础、以观察和测定为依据,以预防为主、各种措施综合应用的系统工程。在实际生产中,水中溶氧水平是否合适不能以鱼虾是否浮头为标志,而应以保证鱼虾食欲旺盛等正常生理需求为标准。我国渔业用水标准规定,养殖水体溶氧连续24 h中,必须有16 h以上大于5 mg/l,任何时候不能低于3 mg/l

溶氧的测定

 

  1、测定方法

    水中溶氧可以用化学方法或仪器法测定

 

合肥桥斯仪器设备有限公司的溶氧测定试剂盒,是一种以化学法为基础、根据目视色差来大体判断水中溶氧范围的现场快速测定方法,比较实用。

 

合肥桥斯仪器设备有限公司依据水产养殖行业对水质溶解氧的检测要求和实际应用中对测试方便性的要求,最新推出桥斯牌YC-DO型水产养殖溶氧仪,该产品采用便携式设计,充电式电池供电,溶氧和温度大屏数字显示等特点,配3米线缆溶氧电极,方便养鱼池,养虾池等现场测试且第一时间掌控水体溶解氧变化,对溶氧异常变化采取相应措施,避免养殖户受损。

 

仪器测定法是一种操作简便、结果可靠的快速测定方法。养殖现场可使用便携式溶氧仪,只要将溶氧探头置于待测水体并轻轻晃动,结果很快就会以数字的形式显示出来。YC-DO型数显便携式溶氧仪响应广大养殖户的需求,是一款质量可靠,价格实惠的水产养殖专用型溶氧仪。但随着养殖集约化程度的提高和管理水平的上升,可以预料在不久的将来,便携式溶氧仪将会成为养殖现场主要的测定仪器。

 

  2、测定时间和频次

一般情况下,每天测定1次即可,测定时间选择清晨和傍晚,由此可以知道池塘一天中最低和最高的溶氧水平,有助于判断水体溶氧是否处于合适范围,尤其是有助于预防“泛塘”等严重缺氧事件的发生。对于刚刚采取过消毒杀藻和施用好氧性微生物改良剂等处理措施的池塘,以及常出现溶氧问题的池塘,应尽可能增加测定频次。

 

  3、测定位置

应在具有代表性的位置测定,所测结果应能反映大多数养殖动物所处环境的溶氧状况,因此不宜仅在水表层或增氧机附近测定。在任何情况下,测定池底溶氧对了解水体的溶氧状况并采取相应措施具有十分有益的参考作用。

Push launch TAG Heuer Monaco V4 TAG Heuer The main (N°001/150) of your "150 decades of TAG Heuer" restricted version TAG Heuer Monaco V4, the world's initially ever belt-driven replica watch having a linear oscillating mass, will probably be available on the biennial Only replica watch auction in Monaco on September twenty fourth.
