Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that crayfish fry cannot be continuously produced in summer and autumn in actual production, and provides a pond culture system and method for controlling the continuous emergence of crayfish in spring, summer and autumn. Through the method of ecological regulation, crayfish The seedlings will come out of the hole after June to meet the demand for seedlings of crayfish in the second half of the year and prolong the breeding cycle of crayfish. This method is highly operable and has great promotion value

Embodiment 1

[0030] One, such as figure 1 As shown, the embodiment of the present invention provides a pond culture system for controlling the continuous emergence of crayfish in spring, summer and autumn, including a pond main body 1, an inlet and drainage device 2, an aeration device 3, and an escape prevention device 4,

[0031] Described pond main body 1 comprises a plurality of sub-pool bodies 11 (aquatic plants 15 are planted on the described sub-pool body 11), a plurality of inner ridges 12 and rain shelter 13, and described sub-pool body 11 and described inner ridge 12 (Inner ridges 12 are raised small mounds in the pond main body) are arranged at intervals, the inner wall of the pond main body is a slope A, the outer circumference of the plurality of inner ridges 12 is a slope B, and the slope of the slope is 1:2.8 (here The slope slope refers to the ratio of the vertical height of the slope to the horizontal width, where the vertical height of the slope is 1m, and the horizontal ...

Embodiment 2

[0049] The gradient of slope A and slope B is changed to 1:2.5; the rest is the same as that of embodiment 1.

Embodiment 3

[0051] The slope of slope A and slope B is changed to 1:3; the rest is the same as that of embodiment 1.

Abstract

The invention provides a pond culture system and method for controlling continuous emergence of shrimp seeds in spring, summer and autumn for procambarus clarkii Girard. The pond culture system comprises a pond main body, a water intake and drainage device, an oxygenation device and an anti-escape device. The method comprises the following steps of 1) constructing the pond culture system; 2) preparing a pond; 3) throwing in parent shrimps and carrying out management; (4) carrying out management in spring; and 5) carrying out management of emergence of the shrimp seeds in summer and autumn. According to the method, through an ecological regulation and control method, the shrimp seeds of the procambarus clarkii Girard come out from caves after June, so that the requirement for the shrimp seeds of procambarus clarkii Girard culture in the next half year can be met, and therefore the breeding period of the procambarus clarkii Girard is prolonged, and the method is high in operability and has a relatively large popularization value.

Description

technical field [0001] The invention relates to the technical field of fishery science application, in particular to a pond culture system and method for controlling the continuous emergence of crayfish in spring, summer and autumn. Background technique [0002] Crayfish, scientific name Procambarus clarkii Girard (1852), belongs to Arthropoda, Crustacea, Decapoda, Cambaridae, Procambarus . Crayfish has biological characteristics such as wide feeding habits, fast growth speed, and strong environmental adaptability, and has become an extremely important freshwater aquaculture economic shrimp in my country. At the same time, the food made with crayfish as the main material has the characteristics of rich nutrition and extremely delicious taste, and is favored by consumers, and the market is in short supply. [0003] However, under the current seed production method and technical level, there is no continuous production technology system for high-quality crayfish seed, and th...
