Problems solved by technology

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 yield of Procambarus clarkii is generally not high. The key links that urgently need to be solved for steady development

Embodiment 1

[0025] Such as Figure 1-2 Shown: three-dimensional Procambarus clarkii artificial shrimp nest, including end plate 1 and row pipe 2, one end of said row pipe is connected with end plate 1; said row pipe 2 is composed of several tubes, corresponding to The position of every pipe has circular hole 3.

[0026] The number of the row pipes 2 is 5 rows, and the number of each row of pipes from top to bottom is 8, 9, 10, 11, 12 successively, which are connected as a whole by welding. The lengths of the row pipes 2 are 25cm, 30cm, 35cm, 40cm and 45cm in each row from top to bottom, and the diameters are 6cm. The number of circular holes 3 corresponding to each tube is 3, and the diameter of the circular holes 3 is 1 cm.

Embodiment 2

[0028] Procambarus clarkii factory indoor cement nursery pond (area 20-100m 2 ), the nursery pond is 1.2m deep, and the water depth is 60-80cm. In the pool, a special artificial shrimp nest specially made for Procambarus clarkii is placed, and the male and female parents of Procambarus clarkii are placed in the pool from July to September. The ratio of male to female is 5:2, and the stocking density of the parental shrimp is 7 fish / m 2 . Set up a shrimp nest every 5 square meters. Set up a microporous oxygenation tray every 5 square meters. every 50m 2 Set up 2-3 biological floating beds in the nursery pool, 5.0-8.0m long and 2.0-3.0m wide. The aquatic plants are water hyacinth, water peanut or duckweed. The cultivation period of water hyacinth is from October to June of the following year. The cultivation period is from June to October. The power configuration of the microporous aerator is every 3000m 2 / kw. During the breeding period, broodstock adopts technical measu...

Embodiment 3

[0030] Procambarus clarkii factory indoor cement nursery pond (area 20-100m 2 ), the nursery pond is 1.2m deep, and the water depth is 60-80cm. In the pool, a special artificial shrimp nest specially made for Procambarus clarkii is placed. From July to September, the male and female parents of Procambarus clarkii are placed. The ratio of male to female is 5:2, and the stocking density of the parental shrimp is 14 tails / m 2 . Set up a shrimp nest every 3 square meters. Set up a microporous oxygenation tray every 5 square meters. every 50m 2 Set up 2-3 biological floating beds in the nursery pool, 5.0-8.0m long and 2.0-3.0m wide.

Abstract

The invention relates to a special artificial three-dimensional shrimp nest for procambarus clarkii and a method for industrialized and efficient artificial breeding, and belongs to the technical field of fry breeding of freshwater economical shrimps. In a fry breeding pond, the special artificial three-dimensional shrimp nest for procambarus clarkii is arranged, a biological floating bed is arranged in the fry breeding pond at the same time, and aquatic plants are planted on the biological floating bed; a disc microporous oxygenation tube is laid in the fry breeding pond; shrimp fry are carefully fed and managed after hatching, and finally drainage is carried out to collect the shrimp fry. The factory indoor cement pool has excellent conditions for artificial fry breeding, and temperatureillumination control, water quality and bait feeding management, shrimp fry collection and other operation are extremely convenient, so that the controllability and management efficiency are greatlyimproved.

Description

technical field [0001] The invention relates to a three-dimensional artificial shrimp nest specially used for Procambarus clarkii and a method for industrialized high-efficiency artificial breeding, in particular to a shrimp nest capable of improving the production efficiency of Procambarus clarkii seedlings and a breeding method thereof, belonging to freshwater economic shrimps seedling technology field. 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 shar...
