Pearl mussel breeding device proper in feeding and oxygenating

Abstract

The invention discloses a pearl mussel breeding device proper in feeding and oxygenating and belongs to the technical field of pearl mussel breeding. The pearl mussel breeding device is formed by structurally combining a hollow floating ball, a hollow rod and a breeding cage, and a mussel body placement mechanism for pearl mussels is suspended in the breeding cage and used for uniformly hang-breeding the pearl mussels in the breeding cage in a centralized manner; cooperation between the hollow floating ball and the hollow rod plays a role in balancing floating, and the whole cooperation structure and a connection pipe in the breeding cage form a sealed connection environment, so that easiness for fertilizer feeding is realized; fertilizer is uniformly scattered in a cage culture area of the pearl mussels in a uniform manner through the connection pipe, so that targeted uniform feeding of the fertilizer is improved effectively. Compared with the prior art that the fertilizer is put intoa breeding pond, the feeding mode is more standard, and precipitation of a lot of organic matter is avoided; through cooperation of the sealed connection environment and an aeration mechanism, quickness and timeliness of oxygenation are improved effectively.

Description

Technical field [0001] The invention relates to the technical field of pearl mussel cultivation, and more specifically, to a pearl mussel cultivation device with moderate feeding and oxygenation. Background technique [0002] Artificial cultivation of freshwater pearls has a long history in my country. At present, the main species of pearl mussels used to cultivate freshwater pearls in my country is Hyriopsis mussels. At present, the cultivation of Hyriopsis mussels is divided into hanging culture or cage culture. Hanging culture is suitable for cultivation in shallow water areas. , It is convenient for daily management and observation. The breeding technicians first prepare a fixed point in the breeding area, and then connect the rope for positioning to the fixed point, and hang the cage for cultivating Hyriopsis on the rope and place the cage. Sink to the bottom. [0003] During the breeding process of pearl mussels, breeding technicians are required to put bait on the pearl musse...

Problems solved by technology

Feed feeding requires a lot of experience. The traditional method is generally manual feeding, throwing fertilizers into the water to increase the content of rich fertilizers in the water body, and waiting for the pearl oysters to absorb the extensive feeding method. Feeding tends to spread the fertilizer too quickly, making it difficult for the mussels to eat in a balanced manner with maximum efficiency, and the pearl mussels can't absorb them all at once after feeding with this traditional culture fertilizer, which leads to a large amount of organic matter precipitation and pollutes the culture water. In addition, in the prior art, aeration pipes are generally arranged at the inner bottom of the culture pond or the culture pond, and then the whole culture pond is subjected to oxygen-increasing treatment. It is often difficult to achieve the effect of increasing oxygen quickly and in a timely manner
