What if there is a water snake in the fish pond?

There are many water snakes in mountainous areas with strong reproductive ability, which has become a big enemy affecting the survival rate of fish in the field. According to the villagers of Lushan Village in Yingkeng Township and Shang Tang Village in Xu 'ao Township, the survival rate of fish released in rice fields is only about 70%, mainly because the fish were eaten by snakes. How to prevent water snakes from hurting fish, the author introduces the following eight prevention methods according to relevant information and combined with mass experience for the reference of farmers.

First, the killing method

1. If water snakes are found, grab them by hand or kill them with hoes and sticks to achieve the purpose of killing them.

It is hot every day in summer, and water snakes like to stick their heads out to enjoy the cool in the fish pond. According to this situation, farmers can use flashlights at night to catch water snakes and clamp them with pliers to achieve the purpose of killing them.

3. Use chicken (duck) eggshells to lure snakes to kill them. The method is to tie the straw into a pile with a rope and become a "scarecrow". Put an appropriate amount of eggshells in the haystack, and then soak the straw stack at the bottom of the fish pond. In order to prevent the haystack from floating, the lower part of the haystack should be pressed with stones to keep it calm and not floating. After a night, pull the draft pile, untie the rope and check whether there are water snakes around the eggshell to eat the eggshell. If there are water snakes, they can be killed in time.

Second, the poisoning method

1. Clear the field with quicklime and disinfect the fish before stocking. For example, the water snake died under the mud in the ground because it couldn't stand the poison of limewater.

2. Poisoning by "annihilating interests". "Shesheling" is a highly toxic pesticide with good snake killing effect. The method is to put a proper amount of rice blast amide in the rice field. The snake was poisoned because of its high toxicity. It is worth noting that the use of this drug to kill snakes must be carried out before stocking fish species, and there are no fish species in the surrounding fields, otherwise poisonous water entering other people's rice fields will also kill fish.

Third, the expulsion law

1. Stick a stick around the ridge every 20 meters. A bunch of women's hair is hung on each stick. The lower part of the hair bundle should be soaked in water. After several days of soaking, the water in the ground gives off a special smell. After smelling it, the water snakes will swim to other places to drive away the snakes.

2. Put rotten chicken (duck) eggs. The method is to put a broken chicken (duck) egg on the ridge every 20-25 meters, and the water snake will swim out after smelling the bad smell, thus driving it away.

3. Install a snake net on the ridge around the fish farm to prevent snakes from entering the field to avoid snakes and protect fish. You can also put realgar on the shore. If put into water, it will pollute the water quality.
