Oxygenation device with feed throwing function for fish culture

Abstract

The invention discloses an oxygenation device with a feed throwing function for fish culture. The device comprises a box body, a feed storage chamber and a bait storage chamber are arranged in the box body, the feed storage chamber is filled with an oxygenating agent, a detachable balancing weight is arranged on the lower wall of the box body, and an oxygen supply mechanism for supplying oxygen is arranged on the box body. The oxygen supply mechanism comprises a mounting box fixedly connected to the side wall of the box body, an opening is formed in the side wall of the mounting box in a penetrating mode, the inner wall of the mounting box is elastically connected with a connecting plate through a first spring, the side wall of the connecting plate is fixedly connected with a sealing plug, and the sealing plug is located in the opening. According to the device, oxygen supply treatment can be carried out on the deepwater area in the fishpond, the oxygen content of water in the deepwater area is effectively improved, a traditional manual throwing mode is replaced, the labor intensity of workers is reduced, the oxygen content of water in the deepwater area in the fishpond can be ensured, and normal growth of fishes living in the deepwater area is facilitated.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to an aeration device for fish farming with the function of feeding feed. Background technique [0002] Fish farming refers to the centralized breeding of various types of fish, which is very important for maintaining food supply, fishing and expanding fishing areas. The oxygen content of breeding water has a very important impact on the growth of fish. The oxygen content of the water directly affects the food intake and growth rate of the fish. Therefore, during the breeding process, the staff will regularly sprinkle oxygenates into the fish ponds to increase the oxygen content in the water, but the oxygenates fall quickly in the water. It will be completely consumed, so that the oxygenating agent can only increase oxygen near the water surface. For the deeper area in the fish pond, because the sunlight cannot reach the deep water, and the deep water cannot directly contact wi...

[0002] Fish farming refers to the centralized breeding of various types of fish, which is very important for maintaining food supply, fishing and expanding fishing areas. The oxygen content of breeding water has a very important impact on the growth of fish. The oxygen content of the water directly affects the food intake and growth rate of the fish. Therefore, during the breeding process, the staff will regularly sprinkle oxygenates into the fish ponds to increase the oxygen content in the water, but the oxygenates fall quickly in the water. It will be completely consumed, so that the oxygenating agent can only increase oxygen near the water surface. For the deeper area in the fish pond, because the sunlight cannot reach the deep water, and the deep water cannot directly contact with the air, resulting in moisture in the deep water The oxygen content is low, but the method of spraying oxygen enhancer cannot improve the oxygen content in deep water, which is not conducive to the normal growth and reproduction of some fish adapted to live in deep water areas, reduces the growth rate of fish, and prolongs the life of fish. The reproductive cycle will have a negative impact on the economic benefits of fish farms
