Introduction of aquaculture facilities

1. The breeding site should choose the ebb, bay or upper and high tide areas supported by ponds and dams, and the natural water intake should be more than 10 days per month. The buried area of culture should be no more than 20 mu. Chengba uses mud-coated construction or stone masonry, the dam is more than 0.5 meters wide and 0.6 meters high, the high tide can cross the Chengba and enter and exit the breeding courtyard freely, and often store more than 1.5 meters of water (including Chengnei ring ditch).

2. The block around the dam shall be made of polyethylene wire with a mesh of more than 9 strands and a mesh of 1 cm. The height of the block shall exceed 0.5 cm, the highest tide level in local history. A 40 cm wide inverted net is added at the upper end of the block. In order to prevent the green crab from escaping from the net, turning the net into the buried, and forming an angle of 45 °~ 60 °with the block.

3. The lower end of the block is buried at the bottom of Chengba. In order to prevent rats from biting the net, a double-layer structure can be adopted between the blocks. Bamboo bamboos with a diameter of more than 10 cm and a spacing of no more than 2 meters should be selected to support the blocking, together with the lower end of the block inserted from the dam below the base of Chengba, and reinforced by climbing rope inside and outside the bamboo.

4. According to the area of the culture courtyard, the inlet and outlet gates shall be set up, but the inside and outside of the gates should be blocked accordingly. Ring ditches or central ditches with a depth of more than 0.8 meters are excavated in the courtyard, and the ditch area accounts for more than 10% of the cultivation area. Chengmian is equipped with concealed objects such as cylinder tiles for green crabs to inhabit.
