Problems solved by technology

[0004] At present, the natural breeding method of self-propagation and self-breeding is mostly used in production, or the shrimp seedlings purchased from outside are used for stocking. The factory-scale and special artificial seedling production mode is rare due to low seedling efficiency and high cost, and it is difficult to carry out in actual production. Therefore, due to the low yield of shrimp seedlings and unstable sources, the improvement of production efficiency is seriously restricted, resulting in the current monoculture and main culture of Procambarus clarkii. The key link that urgently needs to be solved for the steady development of the shrimp farming industry

Embodiment 1

[0030] Such as Figure 1-2 As shown, an earthen pond one-piece greenhouse for efficient artificial breeding of Procambarus clarkii includes a one-piece greenhouse 1, a wave-type breeding soil ridge 2, a three-dimensional special artificial shrimp nest 3, an oxygenation unit 4, and a biological floating bed 5 and artificial breeding pool 6;

[0031] A one-piece greenhouse 1 is provided above the artificial breeding pool 6, and a certain number of wave-like breeding soil ridges 2 are arranged in the artificial breeding pool 6; A certain number of aeration units 4 and biological floating beds 5 are also arranged between every two wave-shaped breeding soil ridges 2.

[0032] One unit of the one-piece greenhouse has a span of 7.5-10.5m and a height of 2.5-3.0m.

[0033] The area of ​​the artificial breeding pond 6 is 2-5 mu, the depth of the pond is 1.5-1.8m, and the water depth is 0.6-1m.

[0034] The bottom width of the wavy propagation soil ridge 2 is 2.5-3m, the upper width ...

Embodiment 2

[0042] Procambarus clarkii earthen pond conjoined greenhouse artificial breeding pond 6 (area 2 mu), 1.5m deep, water depth 0.6m. Arrange three-dimensional special artificial shrimp nests 3 in the pool, release the male and female parents of Procambarus clarkii from July to September, the ratio of male to female is 2:1, and the stocking density of parental shrimp is 3 tails / m 2. Set up a shrimp nest every 5 square meters. An oxygen increasing unit 4 is arranged every 5 squares. every 50m 2 Two biological floating beds 5 are set in the seedling pond, 5.0m long and 2.0m wide. The aquatic plants are water hyacinth, water peanut or duckweed. October. The power configuration of the microporous aerator is every 3000m 2 / kw.

[0043] During the breeding period, broodstock adopts technical measures to strengthen cultivation and management, and feeds high-quality artificial feed twice a day, accounting for 40% of the total feeding amount at 9:00 am and 60% at 18:00 pm, and daily ...

Abstract

The invention relates to an earthen pool integrated greenhouse for efficiently and artificially breeding procambarus clarkii and application thereof, and belongs to the technical field of freshwater economic shrimps breeding. The earthen pool integrated greenhouse comprises an integrated greenhouse, wave-type breeding ridges, three-dimensional special artificial shrimp nests, oxygenation units, biological floating beds and an artificial breeding pond, wherein the integrated greenhouse is arranged above the artificial breeding pond; a certain number of the wave-type breeding ridges are arrangedin the artificial breeding pond; the three-dimensional special artificial shrimp nests which can be placed according to different densities are arranged on two sides of the wave-type breeding ridges;and a certain number of the oxygenation units and the biological floating beds are arranged between each two wave-type breeding ridges. According to the invention, different aquatic plants can be cultivated by applying the biological floating beds in a nursery pond, the cultivation quantity area of the aquatic plants can be effectively controlled, the controllability is greatly improved, the aquatic plants can be used as concealed things of parent shrimps and shrimp fries, and meanwhile, the ecological environment can be improved, and the method is extremely beneficial to improving the survival rate of the parent shrimps and the shrimp fries and the yield at the nursery stage.

Description

technical field [0001] The invention relates to an earthen pond one-piece greenhouse for efficient artificial breeding of Procambarus clarkii and an application thereof, belonging to the technical field of seedling raising of freshwater economical shrimps. Background technique [0002] Procambarus clarkii is native to North America and is commonly known as freshwater crayfish. It belongs to the family Arthropoda, Crustacea, Soft Armada, Decapod, and was brought into my country by the Japanese in 1929. It has been widely distributed in rivers and valleys in my country. In , ponds and major water systems, it has become an important economic species of freshwater aquaculture in my country. Due to the rapid increase in market consumption and export processing of Procambarus clarkii, the number of wild resources is decreasing sharply. Therefore, increasing the production of Procambarus clarkii through artificial breeding has become an important way to meet the needs of processing,...
