Embodiment 1

[0031] A kind of ornamental crab breeding pond, such as figure 1 As shown, it includes an inner embankment 1, a circulating cooling system 2, an outer embankment 3, and an insulation shed 4 from the inside to the outside. Wherein said inland embankment 1 depth is 1.8-2.2m, and described inland embankment 1 is to form the river embankment that is narrow at the bottom and wide at the top with the bottom of crab pond, and the bottom of crab pond also includes silt layer 11, and described inland embankment 1 side The angle between the top and the bottom is 50-60°. And the above-mentioned ornamental crab breeding pond silt layer 11 can be clay or fine flower mud, and a plurality of 2-3cm small stones or small tiles are also scattered on the silt layer 11 . A water layer 12 is arranged on the mud layer 11, and the depth of the mud layer 11 is 0.5-0.8m; the depth of the water layer 12 is 0.8-1.2m. In addition, the inland embankment 1 is also provided with an anti-escape device 13, ...

Embodiment 2

[0033] A breeding method for ornamental crabs, based on the structure of embodiment 1, comprises the following steps:

[0034] 1) Crab pond water injection: inject water into the crab pond, that is, inject water into the inner embankment 1 to form a 0.8m water layer 12; cool the water in the crab pond to 12°C through the circulating cooling system 2; close the heat preservation shed 4 for heat preservation;

[0035] 2) Throwing seedlings: Put the crab seedlings into the pond, the water temperature is 12°C when putting the crab seedlings in, put the crab seedlings into the pond water for 2 minutes, and then put them back to the shore for 22 minutes, repeat 3 times, let the crab seedlings The seedlings adapt to the water temperature; scattered distribution, the breeding density is 1700 crabs per mu;

[0036] 3) Breeding conditions: During the breeding of crabs, open and close the shading cloth to match the natural day and night, and maintain day / night for 4h / 20h; the water tempe...

Embodiment 3

[0040] A breeding method for ornamental crabs, based on the structure of embodiment 1, comprises the following steps:

[0041] 1) Crab pond water injection: inject water into the crab pond, that is, inject water into the inner embankment 1 to form a 1m water layer 12; cool the water in the crab pond to 10°C through the circulating cooling system 2; close the heat preservation shed 4 for heat preservation;

[0042] 2) Throwing seedlings: Put the crab seedlings into the pond, the water temperature is 10°C when putting the crab seedlings in, put the crab seedlings into the pond water for 1.5 minutes, then put them back to the shore for 22 minutes, repeat 4 times, let the crab seedlings The seedlings adapt to the water temperature; scattered distribution, the breeding density is 1800 crabs per mu;

[0043] 3) Breeding conditions: During the breeding process of crabs, open and close the shading cloth to match the natural day and night, and keep day / night for 6h / 18h; the water tempe...

Abstract

The invention provides an ornamental crab breeding pond and an ornamental crab breeding method. The ornamental crab breeding pond comprises an inner riverbank, a circulating cooling system, an outer riverbank and a thermal insulation shed which are sequentially arranged from inside to outside. The inner riverbank and the bottom of the crab pond form an inverted-trapezoidal riverbank structure. A sludge layer is arranged at the bottom of the crab pond, and a water layer is arranged above the sludge layer. The outer riverbank is a compact sludge riverbank. The circulating cooling system is fixed by the inner riverbank and the outer riverbank, is arranged above the sludge layer, and communicates with the water layer. The thermal insulation shed is arranged on the inner riverbank. The ornamental crab breeding pond is reasonable in structure, is low in cost, is environment-friendly, and is easy to achieve. The ornamental crab breeding method is reasonable and is easy to carry out, ornamental crabs can be bred all the year through the method, the breeding cost is low, and the method is suitable for large scale application.

Description

technical field [0001] The invention belongs to the field of aquatic products, and in particular relates to a breeding pond for ornamental crabs and a method for raising ornamental crabs. Background technique [0002] Crabs: Animalia, Arthropoda, Crustacea, Decapods, Reptiles. Crabs are crustaceans, and their bodies are protected by hard shells. In taxonomy, crabs, shrimps, lobsters, and hermit crabs are considered to be of the same kind. [0003] Crab is a kind of food that is delicious and easily absorbed by the human body.
