Acipenseridae fish breeding device provided with air bags

Abstract

The invention provides an acipenseridae fish breeding device provided with air bags, and relates to the technical field of aquaculture. The device includes a culture box; the upper right of the culture box is provided with a water pipe; the water pipe communicates with water source; the upper end of the culture box is provided with a heat preservation shell; the left side of the heat preservationshell communicates with an exhaust fan; the connection section of the exhaust fan and the heat preservation shell is provided with a filter screen; an air outlet of the exhaust fan is connected to anL-shaped air pipe; and the L-shaped air pipe is uniformly provided with semicircular air bags, and the semicircular air bags are provided with air holes. Under the action of the exhaust fan, bait in the culture box can be flew upward from the bottom, so that the bait can float in the water all the time, and waste caused by the sinking and piling of the bait can be avoided; through the arrangementof the filter screen, filtering can be performed on impurities in air, and the impurities can be prevented from entering water to cause pollution to the water; and the device is simple in structure and convenient in operation, can perform automatic drying and stirring on the bait so that the bait can be prevented from wetting and caking, and is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a sturgeon breeding device provided with an air bag. Background technique [0002] Fish meat is rich in animal protein and phospholipids, etc. It is nutritious, delicious, and easily digested and absorbed by the human body. Other parts of the fish body can be made into cod liver oil, isinglass, fish meal, etc. Some fish, such as goldfish and tropical fish, are colorful and colorful, and have high ornamental value. my country has a long coastline, numerous rivers and lakes, and a rich variety of fish. According to surveys, there are more than 1,000 species of freshwater fish in my country, and the famous "four major fish" (herring, grass carp, silver carp, bighead carp), carp, and crucian carp are the main high-quality freshwater fish species in my country; There are about 2,000 species of fish, and the common ones are hairtail, large yellow croaker, and salmon.

Problems solved by technology

[0003] Existing freshwater breeding ponds usually do not use tap water, but divert water from natural water bodies (rivers, lakes, reservoirs, etc.) for use. Due to the inevitable presence of various floating objects and impurities in natural water bodies, it is unfavorable for the growth of fry , at the same time, the feces of the fish tend to accumulate a
