Ecological and high-density snakehead breeding method

Abstract

The invention relates to an ecological and high-density snakehead breeding method. The method comprises the steps that a cement breeding pond is built, a plurality of drainage holes are formed in the bottom of the breeding pond, a plurality of cultivation tanks are formed nearby the breeding pond, cultivation media are scattered and laid in the cultivation tanks, snakehead fry are fed in the pond from early September to the beginning of October after the pond is filled with water, meanwhile, vegetable seeds are sown, after the snakehead fry are fed, water in the breeding pond is changed once every six to seven days in spring and autumn, water in the breeding pond is changed once every 15 to 17 days in summer and winter, and changed water is used for watering cultivated vegetables. Snakehead breeding and vegetable planting are combined, an environment-friendly, pollution-free, ecological and healthy breeding system is achieved, the water in the breeding pond is changed periodically, it is guaranteed that snakehead has a good living environment, changed dirty water is used for watering the vegetables in the cultivation tanks, natural resources are fully utilized, no fertilizer needs to be applied in the vegetable cultivation process, and the green, organic and pollution-free vegetates are cultivated, and are more suitable for being eaten by consumers.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to an ecological and high-density snakehead farming method. Background technique [0002] In recent years, the snakeheaded fish market has become popular, and pond cultured snakeheaded fish has gradually risen. The farming methods in the prior art generally adopt rearranged river ditches or artificially excavated ponds, and carry out breeding production through still water bodies. The breeding technology and breeding technology are relatively backward. The resources cannot be effectively utilized, and the quality and safety of aquatic products cannot be guaranteed. Because black fish have a large appetite and excrement, the accumulation of excrement at the bottom of the pond will quickly make the water quality of the pond fat. Under such an environment, there are a large number of plankton in the pond. Breeding, the water body in the pond will eventually suffer from hypoxia an...
