A feeding pond for Macrobrachium japonica

Abstract

The invention relates to the technical field of shrimp farming, in particular to a feeding pond for Macrobrachium japonicus, comprising a feeding pond body and a temperature-controlled pond body, and the temperature-controlled pond body is arranged inside the feeding pond body or The feeding pool body is outside or intersects with the feeding pool body, the inner area of ​​the temperature control pool body communicates with the inner area of ​​the feeding pool body, and a useful For the heating device for heating the water temperature in the temperature control pool body, a partition board is detachably arranged on the side of the temperature control pool body facing the feeding pool body, and the edge of the partition board is in contact with the temperature control pool body. Cooperate with the side wall of the control tank or the side wall of the feeding tank. In the feeding pond of the present application, the overheating device heats the water in the temperature-controlled pond, so that the risk of death caused by the temperature change of the shrimp seedlings is reduced, and the survival rate of the shrimp seedlings is greatly improved.

Description

technical field [0001] The invention relates to the technical field of shrimp farming, in particular to a feeding pond 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 April, the ...

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
