National aquatic health breeding demonstration farm
and the national agricultural technology promotion technology demonstration main body
2 fish ponds have 7 connecting runners, More than 100,000 kilograms of bass does not "stay" in the fish pond, but "live" in the runners. reporter saw in Jinxiu Paradise that the aerator in the fish pond was running and the fat bass was swimming in the runner.
"Usually, the fish pond produces 2,000 kilograms per mu. We have a runner with a water surface of 450 cubic meters, and the output is 20,000 kilograms. It is energy-saving, environmentally friendly, and has a high output." Huang Jingfeng, the head of Jinxiu Paradise, introduced that the runner connecting the fish pond is 22 meters long, 5 meters wide and 3 meters high. He pressed the automatic bait feeder on the runner, and the calm water surface was immediately filled with the mouths of fish feeding out of the water, and the scene was very spectacular.
Huang Jingfeng is one of the first farmers in Wuhan to introduce bass. In 2014, he tried to raise 50 acres of sea bass in Dongshan to achieve a bumper harvest, and then continued to expand the scale and develop to 300 acres of water surface. Under the rising market demand, how to breed with high quality and efficiency has become a problem that Huang Jingfeng needs to face.
2017, Huang Jingfeng learned about the runner breeding model while studying in other places and introduced it to open the runner to raise fish in Wuhan. After the nano microporous water pushing system is opened, a water flow is formed in the flow channel
According to reports, the principle of flow channel aquaculture is to apply circulating water aquaculture, and an ecological circulation system is formed by relying on the flow channel, sewage discharge facilities, oxygenation facilities, and feeding facilities.
Traditional fish ponds are free-range, and the fish's excrement accumulates in the fish pond, which affects the water quality over time, resulting in fish diseases, deterioration of water quality, and silt of the pond. "Runnel farming is a high-density farming. The excrement and fertilizer water of fish are much higher than that of free-range fish ponds, so it is particularly important to maintain the water quality of the runner." Huang Jingfeng introduced that the runner is designed with a nano microporous water push system, which forms a powerful annular water flow through mechanical waves, and alluvial residual feed and feces into a trough to be collected and removed uniformly. After the outflowing water is absorbed by aquatic plants in the fish pond, it is then drawn back to the runner for recycling.
Huang Jingfeng checks the oxygen supply device in the runner
In order to prevent the "pool overturning" in summer high temperatures, Huang Jingfeng set up a groundwater supply system in the runner. During high temperature periods, groundwater is extracted to adjust the water temperature of the runner, so that the water temperature is kept between 22℃ and 25℃, which is most suitable for bass growth.
"Generally, bass farming is the seedlings lowered at the end of March and will be launched in December. Running can be cultivated off-season, downed at the end of May, and on-market in July the following year, ensuring that it will be launched in two seasons a year." Huang Jingfeng further revealed the secret of off-season farming - runner groundwater supply system, which can help bass overwinter, and traditional Chinese medicine prevention and treatment can help bass survive the spawning period.
Huang Jingfeng raised fish fry in the runner
After the successful runner breeding technology, Huang Jingfeng applied it to fish fry cultivation, and 7 runners can breed more than 3 million seedlings. At present, Jinxiu Paradise has built an integrated industrial chain of seedling cultivation, breeding of adult fish to external sales, and e-commerce sales are also quite considerable.
