What are leeches most afraid of? What are the breeding points?

Speaking of leeches, it is simply a childhood nightmare, because the family planted rice, so in the spring will have to transplant rice, and this time leeches will often mix in the mud, quietly climb to your legs to suck blood, and you may not be aware. Leeches are divided into three types, mainly dry leeches, parasitic leeches, water leeches, what are they usually most afraid of? There are also some people who specialize in breeding leeches. What are the key points of breeding?

What are leeches most afraid of?

As a mollusk, leeches are more afraid of salt, because they do not have skin to protect their bodies, so they are very sensitive to salt. After sprinkling salt, they will form a high concentration of salt water with painful body fluids. At this time, leeches will contract in stress, and the body fluids inside the pond will seep out, which will lead to leeches dehydration and death.

If you are bitten by leeches in the field or in the field, don't pull them with your bare hands, which makes it easy for some of their tissues to stay in the skin, resulting in wound infection and other problems. So we can try dropping a high concentration of salt water on the leech, and it will release its suction cup, lose its moisture and fall right off.

2. What are the main points of leech breeding?

Leech is what we call leech, because it has certain medicinal value, can sell good price in the market, so some farmers have entered this industry. So, what are the key points of leech breeding? Let's take a look.

1. Select breeding sites

Breeding leech had better choose convenient irrigation, north of the back south, sheltered from the wind, sunny places. The depth of the pond is between one meter and one meter two, and the width of the pond is about three meters. The exact length can be determined according to the size of the site. The bottom of the pond is grouted with cement, preferably watertight. The opposite corner of the pond should be set in, and the bottom should be high in the north and low in the south, which is more convenient for irrigation.

The surroundings of the pond are generally filled with sand rich in humus, which is more conducive to the laying of leeches.

2. Pond water quality

If leeches want to grow smoothly, they must have good water quality and suitable environment for their growth. Because the water quality density of artificial breeding is relatively high, it is necessary to change wells in the process of breeding, so as to better prevent pesticide and fertilizer pollution. In the season when the temperature is relatively high, it is generally necessary to keep the water in and out of the place unobstructed, so that the water quality is fresh and has a certain oxygen capacity.

3. Select leech species

The selection of leech species requires that the individual is relatively fat, and it is best to have good activity ability, smooth body surface, bright color and no injury.

4. Leech overwintering

Leeches are very hardy, so they don't freeze easily. Artificial breeding leeches, then in the pond with straw around the warm, help leeches smooth winter.

The above is the introduction of what leeches are most afraid of and what problems they have in breeding. I hope it will help you.
