Embodiment

[0030] 1. Selection of farming area

[0031] The coastal slow water area that reaches the position of the cage mouth when the seawater ebbs is selected as the breeding area. Its seawater has a thriving biota.

[0032] 2. Set up the breeding cage

[0033] The construction of the breeding cage is carried out with the size of 10 meters in diameter and 4 meters in height. The flower cover crab is used as a cultured species. The cage frame is welded by steel pipes with a diameter of 1.2 inches. The bottom net with a hole diameter of 2 cm and a diameter of 0.6 cm is used at the bottom of the cage frame. A fishing net with a layer hole diameter of 0.5 cm is used as a net. There is a pocket-shaped net opening that can be tightened at the upper end of the net. The pocket extends 1 meter. A polygonal artificial reef is arranged at the bottom, and artificial reef holes are arranged therein. The artificial reef is made of cement concrete with a diameter of about 10 centimeters. The ...

Abstract

The invention provides a method for culturing crabs in the seawater by using a breeding cage, which can complete the cultivation of the crabs through the process of selecting a culture area, arranging the breeding cage, putting bait into the breeding cage, bait natural propagation and ingestion as well as harvesting. The breeding cage has the structure that a cage frame is made of a steel tube and is covered by a packet net at the periphery; and a cage body is internally provided with a polygonal artificial reef which is attached and fixed with a decrustation box. The method has the advantages that 1. the crabs can be cultured by the seawater breeding cage; 2. the crabs can be prevented from escaping and being invaded by external natural enemy; 3. the bait can be conveniently thrown into the cage; 4. micro-ecological environment can be created by the artificial reef, so as to be beneficial to generating living bait eaten by the crabs; 5. the decrustation box can be used for ensuring the safety of crab decrustation; and 6. as the crabs cultured inside the breeding cage has high growing speed, the bait can be saved, and the yield is high. Therefore, the method is suitable for being applied to seawater breeding metal of the crabs.

Description

technical field [0001] The invention proposes a method for cultivating crabs in seawater in a culture cage in the field of aquatic animal cultivation. Background technique [0002] Before the present invention proposes, crab can't be cultured in net cage, can only maintain temporary raising by playing air or oxygen in the container in the environment outside seawater. Contents of the invention [0003] In order to imitate the natural environment for cultivating crabs, the present invention proposes a method for cultivating crabs in seawater in a culture cage. The method utilizes a culture cage to cultivate crabs, and solves the technical problem of rapid growth and fattening of crabs. [0004] The scheme that the present invention solves technical problem is: [0005] 1. Selection of aquaculture area: According to the depth of coastal seawater and the conditions of the beach bottom, the shallow water area of ​​the coast in slow water areas is selected as the aquaculture ...
