Problems solved by technology

[0002] Shrimp cultivation refers to the feeding and management of juvenile shrimps to be cultivated into finished prawns that can be eaten by people. Most of the existing prawns are wild shrimps, and the survival rate of artificial feeding is not high, which cannot meet people's needs;
[0003] There are certain disadvantages in the existing methods of cultivating shrimp seedlings. First, the coverage rate of aquatic plants in the traditional shrimp seedling ponds is insufficient or excessive, which cannot meet the growth needs of shrimp seedlings and affect the survival rate of shrimp seedlings. Secondly, the traditional When the shrimp fry are raised, the type of feed is single, and the amount of feeding is not clear, which cannot meet the nutritional needs of the shrimp fry, and may easily cause the phenomenon of appendage defects of the shrimp fry. Finally, there is no small soil ridge inside the shrimp fry pond, which cannot satisfy the crayfish's burrowing. , mating, spawning, can not improve the output of shrimp seedlings, for this reason, we propose a method for cultivating shrimp seedlings

Embodiment 1

[0027] (1) Selection of shrimp fry pond: choose a pond with a water depth of 1.5m and an area of ​​1000m 2 , set two small soil ridges perpendicular to the pool shape in the pool, the soil ridges are 12cm above the water surface, one end is connected to the pool ridge, and the other end is 8m away from the pool ridge, and there are electromechanical equipment for oxygenation and pumping inside the pond ;

[0028] (2) The processing of shrimp fry pond: the pond that selects in the step (1) is carried out clear pond disinfection and fertilization and cultivates water, and in the center of the pond, plant Hydrilla verticillum and water peanut in the shape of a well, around the pond along the edge of the pond water level line 1 Elodea and bitter grass are planted in the shape of a mouth. Reeds and wild rice stems are planted on the small soil ridge in the pond. The coverage rate of aquatic plants is 60% of the pond area. If the aquatic plants are too dense, they should be removed ...

Abstract

The invention discloses a shrimp larva culture method. The shrimp larva culture method comprises the following specific step of selection of a shrimp larva pond, wherein the pond with water 1-1.5 m deep is selected, and the suitable area of the pond is 700-2000 m<2>; two small soil ridges which are perpendicular to the shape of the pond are arranged in the pond, and the parts, exposed out of the water surface, of the soil ridges are 10-15 cm. According to the shrimp larva culture method, different water plants grow in different positions of the shrimp larva pond to stimulate the living environment of shrimp larvae, so that the shrimp larva pond adapts to life habits of the shrimp larvae, and the survival rate of the shrimp larva is improved. When the shrimp larvae are fed with feed, the shrimp larvae are fed with different kinds of feed during different time periods so as to meet nutritional requirements for the growth of the shrimp larvae; different kinds of feed are put, the shrimp larvae are fed according to a certain rate so as to improve the quality of the shrimp larvae, and the situation that due to malnutrition, defects of appendages of shrimp larvae are caused is avoided. The small soil ridges are arranged in the shrimp larva pond so that crayfishes can burrow, mate and lay eggs, and the yield of the shrimp larvae is improved; the spacing between each small soil ridge and the corresponding pond dike is 8 meters, so that it is convenient for a work ship to pass, and a better using prospect is brought.
