First, squid, squid: They are underwater "cleaners." The residual baits and humus that inhabit the bottom of the body of water, and make full use of the residual organic and organic organisms in the water body, can greatly reduce the decomposition of organic matter in the bottom of the pond and reduce the occurrence of fish diseases. Second, squid, black locust, California cricket: They are the "pioneer" in the removal of water in the body. His fierce temperament can feed a large number of wild fish, shrimp, and so on. If one of the three types is properly bred, the growth and reproduction of wild fish and shrimp can be controlled, competition pressure for competition for oxygen with the main fish can be reduced, and natural animal feed can be used to increase fish production. Squid and black quail mainly eat fresh fish and shrimp in water bodies, while carcasses and entrails of animals such as carp, freshwater, white bream and squid, as well as dead fish, are also helpers to remove water pollution. Third, the white pheasant: It is called "water filter." The proper breeding of white fleas can make full use of the natural bait resources such as plankton in the water body, control the water body fatness, and thus regulate the water quality. At the same time, the sea bream is also a "forecaster" of fish's hypoxic floating head. When the white locust appears floating head, it indicates that the water body has begun to lack oxygen, and oxygenation measures should be taken in time. Fourth, grass carp, squid, head lice: it is called the water "hygiene". When there are too many aquatic plants or more weeds in the water body, grass carp, carp, or head carp can be properly reared. This can not only purify the breeding environment, but also use natural food to increase fish production. The head lice also ate rags of grass and fish, and the squid also liked algae in the water. 5. Herring: It is called a fish "diver". It often inhabits the lower layers of the body of water, carnivorous, multi-feeding insect larvae, snails, maggots, and other species, and can properly set up herring on snails, oysters, clams, and shrimps. Tilapia: It is known as the "killer of fish" and "guard". It plays a greater role in the water body. It eats water plants and eats organic detritus, algae and aquatic insects. It not only makes full use of water resources, but also regulates water quality. Tilapia often digs in the water; it can change the substrate. At the same time, Tilapia prefer to eat fish in the water, anchor head and other fish, can reduce the risk of fish diseases. In addition, because tilapia is easily frightened, it can swim in and out of the water to prevent water rats from stealing fish. Seven, red squid, squid, red rofe: it is called "index fish." In cage culture, if you want to check if the cage is damaged, you can stock dozens of red squid, squid or red rofe. If such fish are greatly reduced, it means that the cages have been damaged and they need to be repaired to reduce unnecessary losses. In addition, these fishes, with their bright red color and fast swimming speed, can also prevent the water rat, water leech, etc. from stealing food. Fish.
Removable Oxygen Cylinder Filling System
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure and fill in cylinder with an oxygen booster and compress the oxygen purity to 150bar.
With a customized container, all the parts can be involved in, and removable with a vehicle.

Eight, wild fish: This fish can also be "harm to damage," with considerable use. On the one hand, it is a high-quality natural food for fish such as squid, black porgy, and California quail; on the other hand, after clear ponds are sterilized, they can also use their “test waterâ€. At the same time, the wild fish floating head is the first sign of oxygen deficiency in the breeding water body.
