Green ecological pond co-culture method

Abstract

The invention discloses a green ecological pond co-culture method. The green ecological pond co-culture method comprises the steps that a culture pond is constructed, the culture pond is provided with a centralized culture area and a purification area, and the purification area is divided into a first-stage purification area, a second-stage purification area, a third-stage purification area and a purified water recycling area; and water flow sequentially passes through the centralized culture area, the first-stage purification area, the second-stage purification area, the third-stage purification area and the purified water recycling area by utilizing oxygenation water pushing equipment or a waterwheel type aerator, and returns to the centralized culture area to form running water with directional circulating micro water flow. According to the green ecological pond co-culture method, regional breeding of multiple varieties can be realized, the management efficiency and the feed conversion rate are improved, and the anti-risk capability is improved; aquatic plants are planted in the purification area, water purification fishes are stocked in the purification area, the pond organism in-situ ecological restoration function is achieved, and water ecology is protected; and by means of the oxygenation water pushing equipment, directional circulating micro water flow can be formed in all the areas, water body recycling is achieved, and absorption, utilization and conversion of nutrient substances such as N and P in the water body are promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and in particular designs a green ecological pond co-cultivation method for sea bass and crabs, which is suitable for aquaculture ponds in areas such as sub-regional aquaculture, pond aquaculture tail water that needs to be discharged up to standards, and water resources are insufficient. Background technique [0002] Pond aquaculture is the main way of fishery production in my country. Its aquaculture mode is constantly updated with the advancement of technology, equipment and social development. Demand for quality aquatic products. Especially in order to implement the construction of ecological civilization, reduce water discharge, and protect aquatic ecology, we need to innovate and make breakthroughs in some basic and key aspects such as the breeding technology, models, and methods of main aquatic products, change breeding habits, and optimize The breeding mode adapts to the development r...

Problems solved by technology

[0003] At present, the freshwater California perch, freshwater shrimp and river crab culture ponds in my country mostly continue to use the traditional culture method. The single culture of California perch, the single culture of river crab or the cover of river crab ponds raise the green shrimp model. There are following defects in this culture method: (1) there are few species of culture, Low anti-risk ability; (2) The cultured species are spread all over the pond, which is inconvenient to manage and the feed conversion rate is low; (3) There is no in-situ ecological restoration function in the California perch breeding pond, which is easy to cause pollution of the breeding water body; (4) Large water discharge during the breeding process Large irrigation wastes water resources and may pollute external water bodies; (5) There is no directional water flow in the pond, which cannot realize the recycling of water bodies, and is not conducive to the absorption and utilization of nutrients such as nitrogen (N) and phosphorus (P) and convert
