1.温度测试不同鱼类要求不同的水温。鲢、鳙、草、鲤、团头鲂等,适宜的水温为20～30℃;罗非鱼为25～34℃。可用水质分析仪和溶氧测定仪测定不同水层的水温,以便及时采取调节水温的措施。2.溶氧值测试一般鱼类适宜的溶氧值为3毫克/升以上。小于3毫克/升时,鱼不摄食,生长停止,小于2毫克/升时,就会浮头;0.6～0.8毫克/升时,便会引起死亡。可用上海淀山湖无线电厂生产的 CS-1型水质分析仪、无锡无线电八厂生产的 HT-2型溶氧测定仪等进行测定。只
1. Temperature test Different fish require different water temperature. Silver carp, bighead carp, grass, common carp, bream, etc. The suitable water temperature is 20-30 ℃; tilapia is 25-34 ℃. Water quality analyzer and dissolved oxygen analyzer can be used to measure the water temperature of different aquifers in order to take timely measures to adjust the water temperature. 2. Dissolved oxygen value The average fish dissolved oxygen value of 3 mg / L or more. Less than 3 mg / L, the fish do not feed, growth stops, less than 2 mg / L, it will float; 0.6 ~ 0.8 mg / L, it will cause death. CS-1 water quality analyzer produced by Shanghai Dianshanhu Radio Factory and HT-2 DO Analyzer manufactured by Wuxi No.8 Radio Factory can be measured. only
