鲤鱼的呼吸及养鱼塘缺氧控制的研究
Study On The Respiration of Carp and Oxygenless Control for Fish Pools
-
摘要: 应用FRF-1型鱼类呼吸频率测定仪,连续120h自动测定了池塘中鲤鱼的呼吸频率,首次记录了野外环境中鱼类的呼吸特征,在富有藻类的养鱼塘中,由于气象条件及昼夜的变化,池水溶解氧日变化在0.6-12mg/L,当连续阴雨天,池水溶解氧长时间可低达1mg/L左右,在通常状态下,鲤鱼的呼吸频率随溶解氧的降低而升高,随溶解氧升高而降低,在缺氧状态下,FRF-1呼吸仪可自动启动充氧机。Abstract: The model FRF-1 instrumen, thas automatically detected the FRF (Fish respirationary frequencies) of carp.The special responses of FRF in the field are recorded for the ist time.
In the fish pool rich with algae, the DO is between 0.6 and 12mg/L from day to night.In raining days, DO would be as low as lmg/L for quite a long time.The study shows that the respirating RF of fish increases while the DO is low and reduces while DO is high.
Another advantage of the model FRF-1 is that it can start the aerator when the DO is low
