Problems solved by technology

In the past ten years, it has been widely circulated. The food produced is nutritious and delicious. Restaurants and restaurants that use crayfish as special food on the table are very popular. Therefore, the demand for crayfish seedlings is in short supply, and the improvement of its cultivation technology is increasing. It is becoming more and more prominent, but the general farmers adopt the cultivation method of rice field self-generation and self-propagation, which is rough and slow, not only cannot improve the quality of seedlings, but also cannot meet the needs of farmers in the vast rice field area for crayfish seedlings. There has been no good explanation for this drawback. Technical solutions

Embodiment Construction

[0042] according to figure 1 The cultivation technology of shown crayfish seedling, its essentials are as follows:

[0043] 1. Selection and construction of cultivation sites

[0044] ①Choose a cultivation site with good ecology, quiet surroundings, close to water sources, sufficient water, convenient irrigation and drainage, and non-polluting water sources.

[0045] ②Build a 2,000-3,000-square-meter cement pool with a depth of 1.5 meters and a smooth inner wall of 0.5 meters above to prevent lobsters from escaping. The slope ratio of the pool ridge is 1:2.5~3, the bottom of the pool should be flat, and the inlet and drainage facilities should be well built.

[0046] ③ After the cement pool is built, first pour 0.2 meters of water, and use 10 mg / L bleaching powder solution to splash on the pool wall and bottom to achieve the effect of thorough disinfection.

[0047] ④Transplant or put a certain amount of water-producing plants in the cement pool for crayfish to climb, inhab...

Abstract

The invention discloses a technique for rearing crayfish seedling, which is characterized in selecting and establishing a rearing field, scientifically mating and breeding, scientifically stocking juvenile prawn, scientifically rearing the juvenile prawn, managing water quality and preventing natural enemies and drug hazards. The technique for rearing the crayfish seedling has beneficial effects that: the quality of crayfishes can be improved, and popularization of the intergrowth of the crayfishes and paddies can be realized.

Description

technical field [0001] The invention relates to the field of fish and shrimp cultivation, in particular to the cultivation technology of crayfish seedlings. Background technique [0002] Known fish and shrimps all live in waters such as rivers, lakes and seas, ponds, and wherein freshwater shrimp lives in waters such as rivers, ponds, ditches more, and its growth, reproduction all are spontaneous, self-propagating. [0003] In recent decades, in Qianjiang City, located in the central area of ​​the Jianghan Plain in Hubei Province, farmers have raised a kind of freshwater shrimp in rice fields. The locals call it crayfish, which can grow and reproduce in shallow rice fields, forming a unique The ecological cycle of shrimp and rice symbiosis. Because shrimp farming and rice planting can be symbiotic, and shrimp farming not only does not affect the output of rice, but also opens up a vast new way to get rich in a large number of farmers raising shrimp in rice fields. In the p...
