How are cow locusts farmed? How to breed cow grasshoppers and locusts

Locusts belong to the class Insecta, Orthoptera, Locustidae. According to statistics, there are 223 genera and 859 species in the family Locust. The East Asian locust grows in two generations a year, the first generation is called the summer locust, and the second generation is the autumn locust.

Now captivity can be converted to 3 generations per year. The female locust is millimeter long, and the male locust is millimeter long. Adults are good at jumping and flying.

The East Asian locust has a stout body, a wide range of feeding, strong adaptability, from hatching into a young locust, after 35 days of feeding process can be an adult, about 50 days after fat and strong can be sold, so the time is short, the return is fast. Rearing 10,000 East Asian locust adults can reach 20 kilograms, and its economic benefits are considerable, and the seeds are purchased only once. Self-multiplication dozens of times, eggs hatch locusts, locusts lay eggs, repeatedly, many years of raising, constantly selling money, a female locust can lay more than 35 90 eggs at a time.

The reason why the locust is favored is that its flesh is soft, tender and nutritious. According to expert analysis and determination, its protein content is high, fat content, carbohydrate content, and contains 18 kinds of amino acids and a variety of active substances.

The method of breeding cow locusts in the hall is based on site selection and pond construction, seed stocking, bait feeding, management technology, and reproduction.

1. Site selection and pool building.

Choose a place that is sheltered from the wind and the sun and is convenient for drainage and irrigation to build a source and reserve pool. The pool is 3 meters wide and 1 meter deep, and there is no limit to the length. There are water inlets and drains at the opposite corners of the pool, and some stones and branches are placed at the bottom of the pool for leeches to perch.

Small-scale aquaculture can be cultivated in puddles, barren ponds, and ponds. The inlet and drainage inlets should be fenced with barbed wire or plastic mesh to prevent leeches from escaping.

2. Seed placement.

Artificial breeding is better for money leeches (commonly known as cow leeches), and brown leeches can also be put here. Leeches are very common in rice fields, ponds, streams, and jungles, and should be identified when capturing seeds, and the seed release standard is about 10,000 per cubic meter. The selection criteria are:

Robust, injury-free, large size (20 30 grams is the best), the sample of leeches lays a large number of eggs, has a high hatching rate, and can be processed after 10 months of stocking**.

3. Bait feeding.

Leeches feed on snails, mussels, frogs, turtles, earthworms and mammals. Artificial breeding can use a variety of blood mixed feed, grass meal, and even manure, etc., and about 25 kg of live snails can be put into each mu at one time, so that they can reproduce naturally, and leeches can eat freely. Animal blood is usually fed once a week.

The specific method is: put the blood clots of pigs, cattle and sheep and other animals into the pool, put a piece every 5 meters, and the leeches will soon gather after smelling the fishy smell, and disperse on their own after sucking.

4. Management technology.

The first is to regulate water quality. Although leeches can grow in sewage, but due to the high density of artificial breeding, the water quality should be kept fresh, and at the same time to ensure a certain amount of dissolved oxygen, when the oxygen content in the water is less than 2 milligrams of hail ambush and destruction, leeches will surface and appear uneasy. In summer, the water temperature is high, so pay attention to proper water change.

The second is wintering management. Leeches are dormant in winter, and those stocked in early spring have generally grown well and can be processed**. When fishing, the water is released and then scooped up with a net.

5. Reproduction. Leeches reproduce quickly and have strong regenerative power. The Yangtze River basin is generally spawning from late April to mid-June.

Artificially bred leeches, egg cocoons are laid in the soil at the water's edge of the breeding pond platform, and are oval-shaped. Each leech produces about 4 cocoons at a time, and hatches small leeches about 16 25 days after the cocoon is produced, and 13 35 cocoons can be produced in each cocoon. Baby leeches are brownish-yellow in color and grow rapidly, growing on average 20 mm long within a month of hatching.

Choose the site: choose a pond with leeward and sunny direction and convenient drainage and irrigation as the breeding site, and the pond should be filled with humus-rich sandy soil around the pond. Seedling:

When rearing, it is best to choose leeches that are large and prolific. Daily maintenance: Regularly feed snails and animal blood to the locusts, and change the water once a month.

1. Choose a venue

In the process of raising grasshoppers, it is necessary to choose a pond with leeward and sunny and convenient drainage and irrigation as the breeding site, and the depth of the pond is best between one meter and two meters, and the width is about three meters, and then the bottom of the pond is filled with cement grout, and the surrounding area is filled with sandy soil rich in humus, which is conducive to the laying of grasshoppers.

2. Put seedlings

There are many varieties of grasshoppers, but when breeding, it is best to choose large and abundant leeches, and grasshoppers are hermaphroditic mollusks, each of which can lay eggs and reproduce, so it is necessary to choose grasshoppers that are more than two years old and weigh 30 to 35 grams.

3. Daily maintenance

When raising grasshoppers, it is necessary to regularly feed snails and animal blood to promote its growth and vigor, and it is necessary to change the water for the grasshoppers once a month to ensure that the water quality is clean and hygienic, and control the water temperature between 10 and 40 degrees Celsius to avoid frost damage to the grasshoppers.
