Embodiment 1

[0020] Embodiment 1: referring to Fig. 1, blue crab culture device of the present invention is provided with the rectangular parallelepiped meshed cage case 1 that plastics is made, and the length of rectangular parallelepiped is 60cm, and wide is 40cm, and height is 30cm, and in rectangular parallelepiped meshed cage case Inside 1, there are 2 partitions 2 made of plastic in the horizontal direction, and 1 partition 3 made of plastic in the vertical direction. The partitions 2 and 3 separate the rectangular plastic cage 1 into 20cm long × wide compartments. 20cm x 30cm high grid. When in use, the cuboid mesh cages can be stacked arbitrarily.

[0021] When breeding, the above-mentioned blue crab breeding device is set in the indoor cement pool, and water flow is set in the same direction around the cement pool to drive the water body to rotate, so as to relatively expand the activity space of the blue crab, and at the same time facilitate sewage discharge. Regularly move the ...

Embodiment 2

[0023] Embodiment 2: Referring to Fig. 2, similar to Embodiment 1, the difference is that in the cuboid mesh cage 4, a partition 5 made of plastic is arranged horizontally, and a partition made of plastic is provided vertically 6. Partition boards 5 and 6 separate the cuboid plastic cage 4 into grids whose size is 30cm long x 20cm wide x 30cm high.

Abstract

The invention relates to a device for cultivating green crabs and a cultivating method thereof, relating to a cultivating device. The device and method can avoid fratricide and escape of the green crabs during cultivating, improve cultivating density greatly, cultivating survival rate and production rate in unit water area of the green crabs, and actually achieve three-dimensional water space using and three-dimensional cultivation of the green crabs. The device is provided with a cuboid reticular case, inside of which is provided with at least one clapboard transversely and one clapboard vertically. The cultivating method adopts grading stocking; water flow is set artificially; sweet dew is given at certain amount regularly; sterilization of spraying type is carried out for the green crabs and the cultivating device thereof. Sand filtration is processed for cultivating water; water temperature during cultivating period is kept at 19-32 DEG C, the salinity is 25-32, pH value is 7.5-8.5 and dissolved oxygen is larger than 3.0mg/L; throwing feeding is processed, that is, feed is thrown in each evening during the cultivating period.

Description

technical field [0001] The invention relates to a cultivation device, in particular to a mud crab cultivation device and a cultivation method thereof. Background technique [0002] Due to the habit of crawling or burying at the bottom of the camp, even if the breeding density is not high under normal farming conditions, blue crabs will gather on the bottom surface of the pond, causing overcrowding, aggravating cannibalism, and resulting in high mortality. It has been one of the factors restricting the development of blue crab aquaculture for a long time. Another characteristic of the blue crab breeding process is that when the breeding environment is poor, the water quality deteriorates, the bait is insufficient, or the climate is abnormal, the collective migration and escape of blue crabs often occur. The problem of difficult estimation makes it difficult to scientifically manage the breeding of blue crabs. Therefore, how to reduce or avoid the cannibalism of blue crabs, ...
