Grainworms are a species of Nereididae in the phylum Annelida. They usually inhabit shoals along the coast or in estuaries. They are mainly found in Zhejiang, Guangdong and Fujian provinces in China. They are a delicious food ingredient and can also be used as food. Used as traditional Chinese medicine, it has the effect of reducing swelling and replenishing qi. The breeding method of grass insects is introduced below.

1. Selection and design of the seedling farm

The seedling farm is divided into two parts: the awning and the breeding farm. The top of the awning is built with shading net material and film to cover the breeding tank. , with a breeding tank inside the awning.

2. Selection of mud and water

The mud should be river surface mud, and the mud needs to be filtered first, and the mud should be placed flat in the breeding tank, and then the breeding tank should be cleaned. Release the water and adjust its salinity so that the salinity of the water is 18 degrees and the pH is 5-8 degrees.

3. Preparation before fertilization

Pour filtered water into the plastic box. An oxygenation pump is placed in each plastic box for oxygenation.

4. Seed selection

Select male and female worms that are strong, plump, brightly colored, and uninjured as seed worms.

5. Fertilization

Put the seed worms into a plastic box with water and let them fertilize naturally. When they are artificially inseminated, the fertilized eggs will become " When the 8"-shaped fertilized eggs turn into four swimming spherical fertilized eggs and rotate on their own, use water-filtering gauze to wash them.

6. Stocking

Put the washed swimming spherical fertilized eggs into the breeding tank. The method is to dump the swimming spherical fertilized eggs in the box after washing. Place it in the breeding tank, wait until the four swimming ball eggs turn into pupae and then develop into three-segmented worms to desalinate the water in the breeding tank.

7. Feeding

When the larvae develop into trisegmented insects, start feeding on the first day of desalination of water. When larval holes appear in the soil, drain the water in the breeding tank. Let it go, then sprinkle the food on the surface of the mud for feeding, and then put the filtered water into the breeding tank the next morning, and continue feeding for 20 days. When the cultivation of the wart-nosed Nereis worm is completed, put it Go to the rice fields to stock them until harvest.

Introduction to grass insect breeding methods

1. Establish a grass insect seedling place

If you want to breed grass insect, you must first establish a grass insect seedling place. It can be divided into two parts: the awning and the breeding farm. The awning roof is made of film and shading net materials, and the breeding tank is built inside the awning.

Choose the appropriate mud. Generally, the mud on the surface of the river is good. After selecting, fully filter it, place the filtered mud in the breeding tank, and adjust the salinity at the same time.

2. Select the seeds to be fertilized

Pour filtered water into the plastic box, and place an oxygenation pump in each plastic box to ensure sufficient oxygen.

Generally, only male and female worms with bright colors, plump, strong, and uninjured species can be used as seed worms, and then the selected seed worms are placed in a plastic box filled with water to allow natural fertilization.

3. Feeding points

When the larvae of the grass worms grow to three-sectioned worms, you should start feeding them. When larval wormholes are found in the soil, the water in the breeding tank can be drained, and the prepared food can be sprinkled on top of the mud for the grass worms to eat. Then put the filtered ones into the breeding tanks the next day. In about half a month, they will be cultivated and can be placed in rice fields for cultivation.
