Breeding crayfish: how many shrimps, look at aquatic plants

Crayfish culture is very hot, all want to dry, lobster said I am in crayfish farming "pilgrimage" Qianjiang, crayfish to raise good, aquatic plants. Let's talk about aquatic plants with you today.

The main plants planted in crayfish ponds are submerged plants. At present, the most common are verticillium verticillata (lantern grass), Ellosia (invincible) and Potamogeton crispus (wheat yellow grass).

Verticillium verticillata (Juncus)

Verticillium verticillata starts from spores, and the planting time is from December to February of the following year. March to June is the planting time for fresh grass, which is mainly characterized by high temperature resistance and does not pollute the water quality of the pond.

Lantern grass spores

To cultivate verticillium verticillata, the best way is to use purse seine, when the grass is dominant, remove the purse seine.

Purse seine recommendation

Elozao (eating invincible)

Elodea is fresh, tender, crisp, highly adaptable, rooting at every node, and can grow in large quantities when the temperature is above 5 ℃. It is a kind of high-quality, fast-growing and high-yield submerged plant, but it is not resistant to high temperature, easy to die at high temperature and easy to rot.

Elodea is not the best aquatic plant for raising crayfish. Farmers in Hubei, especially intensive farmers, are slowly eliminating this kind of aquatic plant.

Potamogeton crispus

The first choice for crayfish farming is submerged plant, and rice shrimp is the first choice. Potamogeton crispus is generally sown in mid-October, when the rice is harvested, the soil is prepared and sprinkled with Potamogeton crispus, which germinates in autumn and grows in winter. When our wheat is ripe, the aquatic grass ends its mission. At this time, the rice shrimp is basically over and does not compete with the rice field for space. If the shrimp cannot be eaten, Potamogeton crispus can continue to grow the following year.

Floating plant

Generally give priority to water peanuts and water hyacinth, the coverage rate is not too high.

Water-holding plant

Sophora flavescens is the most common, and it is not easy to grow for crayfish farming.

Sophora flavescens, which was raised at the beginning of September, has grown new roots after transplanting.

It is necessary to raise grass to raise shrimp, especially in crayfish intensive culture ponds, which to a certain extent determines the commercial nature of crayfish, a variety of several aquatic plants can achieve good results. I hope that you who raise shrimp will succeed in raising crayfish and realize your original ambition.
