Problems solved by technology

[0008] It can be seen that there are certain defects in the existing mud crab breeding models, and more farming models need to be developed to increase the output of mud crabs to meet market demand
In addition, the current utilization of coastal wetlands has problems such as loss of original habitat, serious pollution of sea areas, and broken coastal landscapes. It is urgent to develop a sustainable utilization model

Embodiment 1

[0040] see figure 1 , a blue crab culture device, comprising a culture body 1 with a mud crab accommodation space, the mud crab accommodation space includes a connected flowing water section 2 and an embedded section 3, and the flowing water section 2 is densely covered with water supply inlets The first exchange holes 4, the buried section 3 are evenly distributed with the second exchange holes 5 for sediment to enter. The middle part of the breeding body is provided with a feeding hole 6, the port of the flowing water section 2 is connected with a movable pipe cap 7, and the movable pipe cap 7 is densely covered with a third exchange hole 8, and the port of the buried section 3 is connected with a cleaning port 9 .

Embodiment 2

[0042] see figure 2 , a mud crab culture device, its implementation is similar to that of Example 1, the difference is that: the main part of the mud crab culture device is T-shaped, simulating the caves in the wild environment, and providing more hiding places for mud crabs space.

Embodiment 3

[0044] The method of cultivating blue crabs in tidal creeks

[0045] 1) Make mud crab breeding devices of different specifications according to the following table 1, and make 3 groups for each specification, and the production material is PVC pipe;

[0046] Table 1 Production Specifications of Aquaculture Device

[0047]

[0048]

[0049] 2) At the beginning of June 2017, the experiment was carried out in the mangrove area in the sea area of ​​Xinji Village, Fangcheng District, Fangchenggang City, Guangxi;

[0050] Place the blue crab culture device described in step 1 in the tidal creek of the mangrove area respectively, the culture device is perpendicular to the water flow direction, and forms 10° with the horizontal plane, the first exchange hole area is placed in the tidal creek, and the second exchange hole area is buried In the sediment, the reserved rectangular hole for feeding (1.5×5cm) is upward, and the specific installation method is as follows: image 3 sh...

Abstract

The invention relates to the technical field of coastal wetland sustainable utilization and aquaculture, and provides a blue crab culture device and a method for culturing blue crabs in tidal creeks. The blue crabs are cultured in the tidal creeks, the natural advantages of tidal creek flowing water after ebb tide are utilized, the environment requirement for survival of the blue crabs is met, and residual feed or excrement is automatically removed; the tidal creeks with high biomass provide part of food sources for the blue crabs, and it is guaranteed that the culture quality of the blue crabs is close to nature; residual feed generated by culture can provide food for animals in the surrounding area, and the animal biomass of the surrounding habitat can be improved; and low-concentration excrement is beneficial to the growth of plants. A sustainable way is provided for utilization of coastal wetland, a new space is opened up for culture of the blue crabs, and the economic income of coastal residents can be increased by harvesting the blue crabs.

Description

technical field [0001] The invention relates to the technical field of sustainable utilization of coastal wetlands and aquaculture, in particular to a mud crab breeding device and a method for cultivating mud crabs in tidal trenches. Background technique [0002] The blue crab is delicious and has high nutritional value. As a high-end food material, it is widely favored by people all over the world, especially the natural blue crab in the mangrove area is more precious. With the rapid increase of coastal population density, people's demand for blue crabs is also increasing day by day. The amount of natural blue crab resources in the natural environment has long been unable to meet the market demand, and the artificial breeding industry of blue crabs has emerged. At present, there are mainly the following breeding modes for blue crabs: [0003] In the pond culture mode, the blue crab seedlings (mainly bean crabs) are put in the pond, and the bait (prawn feed or fresh miscell...
