Ecological high-yield circulating breeding system and method

Abstract

The invention discloses an ecological high-yield circulating breeding system and method. The system is characterized by comprising a plurality of fish breeding pools (1) of the area ranging from 200 square meters to 700 square meters, a sealed greenhouse (2) is arranged on the fish breeding pools, an air inlet is formed in one end of the greenhouse, an air supply device (3) is additionally arranged on the air inlet, an air outlet is formed in the other end of the greenhouse, natural water drainage openings (6) are formed in the bottoms of the fish breeding pools, and water supplementing pumps (4) are installed on the periphery of the fish breeding pools and are communicated with a circulating water source (5). By means of the system and method, the green ecological circulation is achieved, no chemical medicine is used in the whole system or the whole breeding process, full-food-chain recycling is achieved for waste water and excrement produced during fish breeding, the commercial high-yield breeding that 50,000 kilograms of snakehead and 25,000 kilograms of bass are produced per year can be achieved, grass carp, chub, yellow catch eel and other high value-added aquatic products can be produced, and meanwhile, completely-green organic rice, fish, shrimp, crab and other by-products high in economic value can be produced in paddy fields.

Description

technical field [0001] The present invention relates to an aquaculture system and method, in particular to a fish ecological breeding system and method that do not use hormones and harmful drugs, and specifically to an ecological high-yield circulating fish that can achieve a yield of 100,000 jin of commercial fish per mu. Cultivation systems and methods. Background technique [0002] Most of the current farmed fish are cultured in original ponds. The water surface is large, the water quality is difficult to control, and there are many diseases and insect pests, which are difficult to control. Yield is difficult to improve again, and current per mu yield is no more than 5000 jins, feeds bait utilization rate low, only utilizes 70% feed at present, and the rest is wasted, causes breeding cost height. The feed that sinks into the bottom of the pond quickly rots and deteriorates, affecting water resources. At the same time, the water quality changes rapidly, the amount of sewa...

Problems solved by technology

[0004] The purpose of the present invention is to invent an ecological high-yield fish culture system and provide a corresponding high-yield fish culture method in response to the problems of low yield, poor meat quality, and serious harm to the ecological environment and human health caused by the use of drugs in the existing original pond
