Disease Outbreaks and Emergency Treatment After Introducing Inferior Quality Rice Field Eels into Eel Ponds or Net Cages
(1) Disease outbreak situation: After inferior quality rice field eels are introduced into eel cages or eel ponds, they generally develop disease within 2 to 7 days, and mass mortality occurs around 12 days. When disease breaks out, a method combining Chinese herbal medicine and chemical fishery drugs should be used for treatment to control the infection. (2) Emergency handling: ① Search for and remove floating-head eels, exposed-body eels, and dead eels 2 to 3 times during the daytime each day; ② Change the water once every morning and thoroughly inspect for and remove dead eels; ③ At night each day, use electric light for illumination and search for and remove diseased eels from aquatic plants 1 to 2 times.

How was the trial on early breeding of rice field eel fry in greenhouses carried out?
At present, cage culture of rice field eels is concentrated on collecting fry in July, which gives a high survival rate and low farming risk.

How can this problem be solved? We carried out a trial on early breeding of rice field eel fry in greenhouses, and a brief summary of the trial is as follows: 1. Trial conditions 1.
