Technical Field
The invention belongs to the technical field of aquaculture and cultivation equipment, and particularly relates to a method for intercropping acrossocheilus fasciatus in a crab pond.
Background
Crabs are popular among consumers because of their high nutrition and delicious taste. With the improvement of living standard, the consumption of crabs is also increased. The pond culture crabs become the getting rich door of friends of farmers. Of course, the cultivation of crabs in ponds requires certain techniques, and some management measures are also understood. Large-scale culture is common in the existing aquaculture, but the water body is rich in nutrient elements such as nitrogen, phosphorus, potassium and the like, so that the duckweed is easy to proliferate in a large area, and further the reoxygenation of the water body and the illumination of submerged plants are blocked, so that the submerged plants die in a large area. Once the number of submerged plants is reduced, the crab shell-falling time becomes serious due to the lack of self-killing of the shelter, and the dead submerged plants further consume oxygen in the water body, resulting in deterioration of water quality, thereby affecting crab yield.
Because the existence of crab is considered in current crab breed, the mode of artifical salvage is mostly adopted, but wastes time and energy, and gets rid of the effect unsatisfactory.
Disclosure of Invention
The invention provides a method for intercropping acrossocheilus fasciatus in a crab pond, which is used for solving the problems that in the prior art, when crabs are bred, duckweeds influence the water ecology, when the duckweeds on the water surface of a certain water area reach a certain level, the dissolved oxygen in water is reduced, the water quality is rapidly deteriorated, and special periodical salvage is needed, so that the cost is increased.
