Abstract

The invention discloses an air-free stone breeding container. The air-free stone breeding container comprises a sealed water tank, wherein a lower tapered flow guide part is arranged at the part, close to the bottom, at the inner side of the water tank, an upper tapered flow guide part is arranged at the part, close to the top, of the inner side of the water tank, an oxygen-adding water spraying pipe is arranged on one lateral face of the water tank in a penetrating mode, the oxygen-adding water spraying pipe is connected with the lateral face of the water tank in a matched mode through a bearing, a working end of the oxygen-adding water spraying pipe is connected with a water spraying port, a free end of the oxygen-adding water spraying pipe is connected with a water pump in a sliding matched mode, the water pump is provided with a water sucking pipe arranged on the lateral face of the water tank in a penetrating mode, and the oxygen-adding water spraying pipe is connected with a motor through a traction wheel and a belt. The air-free stone breeding container has the advantages that oxygen adding or sterilization operation is carried out on surface water and bottom water according to needs, and problem products can be destroyed under emergency situations.

Description

technical field [0001] The invention relates to a super-intensive aquaculture equipment, in particular to an airless stone culture container. Background technique [0002] In aquaculture, dissolved oxygen is an important factor affecting the food intake, growth rate, feed coefficient and health status of fish and shrimp. According to relevant data, the feed coefficient of fish when dissolved oxygen is 3 mg / L is greater than that when it is 4 ppm Double, the growth rate of fish grown in dissolved oxygen 7ppm is 20%-30% faster than that of fish grown in dissolved oxygen 4PPm, while the bait coefficient is 30%-50% lower. When the amount of dissolved oxygen in the water reaches above 4.spPm, the fish's appetite will be greatly enhanced. For this reason, my country's "Fishery Water Quality Standards" stipulates that the dissolved oxygen (DO) in aquaculture water must be kept at least 5mg / L for more than 16 hours in a 24-hour day, and should not be lower than 3mg / L at any time. ...
