Shrimp seed rearing method based on floor heating type greenhouse and shrimp pond adopting method

Abstract

The invention provides a shrimp seed rearing method based on a floor heating type greenhouse. The method includes the following steps that (1) a shrimp pond is arranged in the greenhouse, (2) the shrimp pond is sterilized and filled with water, (3) male shrimps and female shrimps are reared separately, (4) the sexually mature male shrimps and the female shrimps are reared separately, (5) the male shrimps and the female shrimps are mated on suitable conditions and water temperature is controlled between 28 DEG C to 30 DEG C, and (6) egg-carried female shrimps incubate on suitable conditions and water temperature is controlled between 26 DEG C to 28 DEG C. A rearing box is arranged, so that the yield of shrimp seeds is improved, young shrimps are prevented from being eaten by the female shrimps, and the survival rate of the young shrimps is improved. Shrimp mating water temperature is manually simulated by controlling the water temperature, and seed rearing can be carried out many times a year. Temperature in the greenhouse can be quickly raised and maintained on low-temperature cold days and can be quickly lowered and maintained on high-temperature hot days, so that the situation that in extreme weather, shrimp eggs do not adapt to surrounding environment and accordingly the death rate is increased is avoided. The invention further provides the shrimp pond adopting the method.

Description

Technical field [0001] The invention relates to a method for cultivating shrimp larvae in a greenhouse, in particular to a method for cultivating shrimp larvae based on a floor-heated greenhouse and a shrimp pond using the method. Background technique [0002] The breeding and breeding temperature range of crawfish is very narrow. Most of the breeding methods for this type of shrimp in the prior art can only achieve seedlings once a year, which cannot achieve high-efficiency marketization; moreover, the breeding environment of crawfish requires good water quality, There are few sediments, and the temperature of the water itself cannot be lower than 7 degrees. The prior art breeding method cannot solve the temperature control and water quality problems well. In addition, in the process of aquaculture, the feed residue and aquatic excrement cannot be cleaned up on time. Affecting water quality, coupled with the lack of oxygen in the water body, will reduce the survival rate of aqua...

[0002] The cultivation and breeding temperature range of crawfish is very narrow, and most of the cultivation methods for this shrimp in the prior art can only realize seedling breeding once a year, and cannot realize the marketization of higher efficiency; and the cultivation environment of crayfish requires good water quality, There is less sediment, and the temperature of the water itself cannot be lower than 7 degrees. The breeding methods of the prior art cannot solve the temperature control problem and the water quality problem well. In addition, in the process of aquaculture, due to the feed residue and aquatic excrement that cannot be cleaned up on time, there will be Affecting water quality, coupled with the lack of oxygen in the water body, will reduce the survival rate of aquatic products, thus resulting in low yields of shrimp seedlings and low returns
