In the pond, healthy farming is simple. The traditional old pond fish farming method is changed into a new mode of concentrated farming in the water tank. It is a new technology of high-efficiency, energy-saving, environmentally friendly and green ecological health farming. The fish cultured by the method has the advantages of fast growth rate, high survival rate and low feed coefficient, which can greatly improve fish production and output value, and increase economic benefits of culture. Therefore, today Xiaobian will introduce the circulation of healthy farming in the pond, hoping to let everyone have a certain understanding of this.
First, the basic principle
The principle of circulating healthy farming in ponds is to use kinetics. By adding power equipment, the static water in the pond is pushed by external force, so that the still water in the pond flows into circulating micro-flowing water, and then the bait residue is taken away by the sewage treatment system. Residues such as fish manure, so as to achieve the effect of regulating and purifying water quality, increasing dissolved oxygen in pond water, improving pond water environment, improving bait utilization, and promoting fish growth and development.
Second, the pond selection
Choose a place with flat terrain, convenient transportation, good water quality, good soil water retention, and hardness and ventilation. The pond area is preferably 20-50 mu, and the water depth is 1.5-3 m. The shape is rectangular and east-west, and the aspect ratio is 2:1-3:2.
Third, the functional partition
1. Operating platform area: 2-3m wide, 5-6m long, area 10-20m2, mainly used for installation of supporting equipment, such as electric motor, water pusher, feeding machine and other daily feeding management equipment.
2. Tank culture area: The single tank is 4-6m wide, 20-25m long, and the area is 80-150m2. The rectangular fish tanks are built side by side. The total number of tanks can be determined according to the size of the pond. The m3 water body can produce 60-90kg of fish.
3, bait feces area: 2-3m wide, 5-6m long, area 10-18m2, built in the rear end of the tank culture area, mainly used to collect the residual bait feces of the fish, in order to install the sewage equipment Concentrated sewage.
4, water purification area: 6-8m wide, 10-15m long, 60-120m2 area, built in the front end of the tank culture area, mainly used to supply fresh water body in the tank culture area.
Fourth, the tank construction
The fish tank body is built along the north-south direction. The civil construction materials can be selected from brick cement wall (economical and durable), glass steel (high cost), PVC material (not durable), stainless steel (high cost), etc. Which kind, depending on its own economic conditions, 10-20% of the area outside the culture tank can be planted with ornamental aquatic plants such as lotus and water spinach.
Fifth, equipment preparation
1. Power system: The electric pump with the appropriate amount and power is configured to lift water.
2. Pushing water system: The water pushing device is configured to promote the micro-flow of the pond water body, so that the entire pond water body forms a microcirculation flow.
3. Oxygenation system: Configure a suitable number of aerators to increase the dissolved oxygen in the water.
4. Sewage system: Configure the sewage disposal device to collect waste residue such as residual bait and fish manure in time to reduce the pollution generated during the breeding process.
5, feeding system: the configuration of automatic feeding feed machine, fixed point, timing, quantitative feeding of bait feed, can reduce manual operations, but also improve work efficiency.
6, electromechanical system: In addition to the installation of the power supply, it is best to equip a spare engine to prevent power outage, but also to ensure uninterrupted power supply.
7. Internet of Things system: Install the Internet of Things to realize intelligent operation and monitoring of the breeding process, and improve work efficiency and economic benefits.
6. Farmed fish
The fish cultured in the pond are grass carp, squid, squid, squid, stingray, etc. It is not suitable to breed fierce fish such as black fish. The stocking size of the fry is 50-100g, and the stocking density can be determined according to the water body area, fish type, planned yield and other factors in the tank of the culture pond. At the same time, the shrimp can also be raised, the squid, the squid, the squid Etc., improve the economic benefits of farming.
