Live fish can be kept fresh by acupuncture
A marine biologist in Japan has invented a method of keeping live fish fresh by acupuncture. This method uses the acupuncture technique of traditional Chinese medicine, in which the needle is inserted into the brainstem nerve point of the fish, and the live fish goes into a dormant state after a few minutes. According to the experiment, after the live fish is dormant by acupuncture points, it can be dormant for about 10 hours, and the body in the dormant state enters the lowest maintenance state and will not deteriorate and stink. In this way, it can keep fresh without freezing.

Prevention of fulminant hemorrhagic disease in fish
In autumn, with the rapid growth of fish and the increase of pond culture density, the water quality is easy to deteriorate, and the reproduction speed of various pathogenic pathogens is accelerated, which easily leads to the occurrence of fulminant hemorrhagic disease. Preventive measures are as follows: 1. Before entering the pool, the seedlings must be disinfected by soaking in 1%-2% salt water. The soaking time depends on the constitution and temperature of the fish. When conditions permit, the fingerlings can be soaked with fulminant hemorrhagic vaccine. 2. Change water and oxygenation in time. Keep the water fresh and change it frequently. If the conditions limit the inconvenience of changing water, raw stone can be used.
