A method for cultivating Macrobrachium japonica

Abstract

The present invention relates to the technical field of shrimp farming, in particular to a method for cultivating Macrobrachium japonicus, comprising the following steps: step 1, feeding shrimp seedlings: then pumping out 40-60% of the water in the temperature-controlled pool, and then Pour the water body of the shrimp seedling cultivation field of equal volume into the temperature control pool, and then put the number of shrimp seedlings into the temperature control pool body after equalizing the number of shrimp seedlings according to the number of temperature control pool bodies; step 2, adaptive breeding: in step 1, the shrimp seedlings After the feeding is completed, the shrimp seedlings are cultivated in the temperature-controlled pond for 4-10 days; Step 3, large pond cultivation: After the shrimp seedlings are cultivated in the temperature-controlled pond for 4-10 days, the clapboard in the temperature-controlled pond is removed; Step 4, Adult prawns are harvested. In step 2, when the temperature of the water body in the temperature-controlled pool is lower than 16° C., the temperature of the water body in the temperature-controlled pool is raised by a heating device. The breeding method of the application can greatly reduce the risk of death of shrimp seedlings due to emergency response, and can also reduce the risk of death of shrimp seedlings due to temperature changes, and improve the survival rate of shrimp seedlings feeding.

Description

technical field [0001] The invention relates to the technical field of shrimp cultivation, in particular to a cultivation method for Macrobrachium japonicus. Background technique [0002] Macrobrachium japonicus, also known as freshwater shrimp, belongs to the subclass Molecula, Decapod, Paradea, Spratidae, Macrobrachium, mainly distributed in Japan and China, and is one of the main economic shrimps in freshwater in my country. Except for the western plateau area, it is widely distributed in lakes, rivers, reservoirs, ponds and ditches all over the country. It has the characteristics of miscellaneous food habits, fast growth, high fecundity and strong disease resistance. Macrobrachium japonicus has a very high protein content, and the shrimp shell is an important chemical raw material. It is widely used in many aspects such as textiles, food, environmental protection, and medicine, and has high economic value. [0003] In the current breeding method, usually from March to A...

Problems solved by technology

[0006] In order to solve the above problems, there is currently a method of building a film-insulated greenhouse on the big pond. Although this method can control the water temperature of the big pond well, the air in the shed is not circulated, and it is prone to various diseases and lead to shortfalls in the big pond. Oxygen and other issues, so it is necessary to set up a ventilation device and a large number of oxygenation equipment in the greenhouse. The construction of the greenhouse, the purchase, installation and operation of the ventilation device and oxygenation equipment, as well as the later maintenance have greatly increased the cost of breeding, and When dealing with extreme weather such as hail and hurricanes that may exist in summer, the disadvantage of greenhouses is obvious, which not only increases the uncontrollable factors in the breeding process, but also further increases the cost of breeding
