Embodiment 1

[0018] In the breeding season of the ornamental crayfish Blue Devil Shrimp, the broodstock size of the breeding Blue Devil Shrimp is larger, and a PVC tube with a diameter of 8cm and a length of 30cm can be used to make a spawning shrimp tube. The inclination of the first end of the spawning tube 2 is 45 degrees. If the number of crawfish broodstock in the breeding pond is large, the number of shrimp tubes can be increased appropriately. The spawning tube 2 can be arranged in 8 rows from 8 to 15 rows from top to bottom, and glued on the length 1.3m, width 0.7 m the hard plastic tail plate 3, fasten it with the fixing ring 1, and use the handle 4 to place the completed breeding nest in the ornamental crayfish spawning pond, and the mated blue devil shrimp females can enter separately Each spawning tube is used for spawning and holding eggs to breed, so as to achieve the purpose of batch breeding of crayfish seedlings of the blue devil shrimp.

Embodiment 2

[0020] During the breeding season of mini crawfish crawfish, because the broodstock of crawfish used for breeding is slightly smaller, a PVC tube with a diameter of 5 cm and a length of 20 cm can be used to make the spawning tube 2 and the inclination of the first end of the spawning tube 2 The temperature is 60 degrees. If the density of crayfish broodstock in the breeding pond is not too high, the spawning tube 2 can be arranged in 5 rows from 6 to 10 rows from top to bottom, and glued on a rigid surface of 0.8m in length and 0.4m in width. On the plastic tailboard 3, fasten it with the fixing ring 1, and use the handle 4 to place the completed breeding nest in the ornamental crayfish spawning pond, and the mated mini orange crayfish females can enter each production separately. In the egg tube, spawning and holding eggs are carried out to achieve the purpose of batch breeding of mini orange crayfish shrimps.

Embodiment 3

[0022] During the breeding season of the white crayfish, the broodstock of the white crayfish for breeding has a moderate body length. The spawning tube 2 can be made of a PVC tube with a diameter of 7 cm and a length of 25 cm. The inclination angle of the first end of the spawning tube 2 is 50 degrees. Laying tubes 2 are arranged in 6 rows from 7 to 12 rows from top to bottom, glued on the rigid plastic tail plate 3 with a length of 1m and a width of 0.5m with glue, and fasten it with the fixing ring 1 and fix it with the handle 4. The prepared breeding nest is placed in the ornamental crayfish spawning pond as a whole, and the mated ornamental white crayfish females can enter each spawning tube to lay and hold the eggs to reproduce, achieving batch reproduction of ornamental white crayfish seedlings. the goal of.

Abstract

The invention relates to a large-scale reproduction nest of ornamental crayfish, comprising spawning pipes arranged in a fixing ring, wherein a tail board is fixed at tail ends of the spawning pipes; the head end faces of the spawning pipes form acute angles with a horizontal plane; a handle is arranged at the top end of the fixing ring; the spawning pipes are stacked and form an isosceles trapezoid-like distribution; axes of two adjacent layers of spawning pipes are configured to be staggered; the arrangement number of the spawning pipes from top to bottom are sequentially increased; and the length of the spawning pipes at the upper layer is less than the length of spawning pipes at the lower layer. The invention has the following advantages that the reproduction nest is lower in manufacturing cost than a ceramic pot, compact in structure, not likely to break and durable than the ceramic pot so as to benefit industrial applications on ornamental aquatic animal production, particularly high in reproduction efficiency to ensure that the shortages that a single artificial cave is low in reproduction efficiency and incapable of batch emergence are overcome, particularly suitable for the large-scale reproduction and spawning of ornamental crab and crayfish and can be used for large-batch industrial breeding of the ornamental crayfish to ensure that demands of aquatic animal markets are satisfied.

Description

Technical field [0001] The invention relates to a large-scale artificial breeding of ornamental crayfish ovaries, in particular to a large-scale breeding nest of ornamental crayfish. Background technique [0002] Ornamental crayfish has the breeding habit of spawning in caves during the entire breeding and spawning period. In the factory farming of ornamental crayfish, to realize large-scale artificial reproduction, it is necessary to provide ecological artificial ovaries for female shrimps in the nest. Concealed spawning and hatching. At present, the aquarium industry usually uses a single clay pot, carbon tube, etc. as a breeding shrimp nest for crawfish. This kind of clay pot breeding nest has a higher cost, is easy to break, and is not durable; the two have a single cave reproduction efficiency. The low level is not conducive to the large-scale reproduction and production of ornamental crayfish, resulting in insufficient market supply, resulting in high prices for ornamental...
