What about the "stress" reaction of eel species?

The "stress" reaction of eel species is mainly concentrated in the box stage of eel species. Eel species produce "stress" reaction because they do not adapt to the new living environment, or because of the great change of climate and water temperature. The "stress" response is mainly manifested in the grass on the rice field eel, moving slowly, refusing to eat, weak, the immune function decreases or disappears, and the mortality rate is as high as 90% in severe cases. This is a serious disease in Monopterus Albus culture at present.

Prevention and treatment of stress reaction of eel species

The main results are as follows: 1. Correctly mastering the season of eel entering the box is the best way to prevent "stress" diseases of ricefield eel. According to our experiments, winter is the best time for stocking, because this stage is the peak season for adult eel to catch and sell, the seedlings are easy to buy, the water temperature is low, and the bacterial activity is not strong. Secondly, from late June to mid-July, the eel species passed natural fattening and recovered their physique during the overwintering period. the seedlings are generally strong, and the weather changes little, and the water temperature is relatively stable, all above 25 ℃. The seedlings will not cause "stress" reaction when entering the box.

2. Reasonable selection of eel box time is another unique way to prevent "stress" diseases of ricefield eel. In the experiment, by observing the weather changes, we chose a sunny day for more than 2 days and ensured that the eel had fine weather for 2 days. The effect was very obvious.
