Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of freshwater fish farming, and specifically relates to a captive bucket for green farming of freshwater fish. Background Technique
[0002] Freshwater fish are fish living in inland freshwater waters such as rivers, lakes, and reservoirs. There are many species, such as grass carp, crucian carp, carp, etc. They are mostly adapted to the freshwater environment, feed on aquatic plants, plankton, benthic animals, etc., are relatively sensitive to water quality changes, and are an important part of the freshwater ecosystem. They not only provide rich food resources for humans but also maintain the aquatic ecological balance.
[0003] Most of the existing freshwater fish are cultured in fish ponds. The freshwater fish cultured in fish ponds are prone to phenomena such as gathering in groups and local oxygen deficiency. When fishing or grading, it is necessary to drain the fish pond water or use tools for fishing, which is troublesome. At the same time, as the service life of the fish pond increases, breeding wastes such as residual bait and feces will settle in the fish pond, which is inconvenient for later cleaning and has a poor breeding effect on freshwater fish. For this reason, we propose a captive bucket for green farming of freshwater fish. Content of the Utility Model
[0004] The purpose of the utility model is to provide a captive bucket for green farming of freshwater fish to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A captive bucket for green farming of freshwater fish, including a captive bucket body. An outlet and sewage discharge port is opened at the bottom of the captive bucket body, and a sewage discharge pipe is connected to the outlet and sewage discharge port. A sewage suction pump is installed on the sewage discharge pipe. The inner bottom wall of the captive bucket body is connected with a fixed anti-escape net. Above the fixed anti-escape net and along the inner wall of the captive bucket body, there is an oxygenation circular pipe. A plurality of oxygen outlet holes are opened on the oxygenation circular pipe. A plurality of support pads are also provided on the inner wall of the captive bucket body, and a movable fishing net is arranged on the support pads.
[0007] Further: An oxygen generator is arranged on the outer side of the captive bucket body, and an oxygen outlet of the oxygen generator is connected with a communicating air pipe. The other end of the communicating air pipe is communicated with the oxygenation circular pipe.
[0008] Further: Four connecting rings are installed on the upper surface of the movable fishing net, and the four connecting rings are distributed in a circular array at the top of the movable fishing net.
[0009] Further: The upper part of the captive bucket body is cylindrical, and the lower part of the captive bucket body is conical.
[0010] Further: The size of the filtering holes on the movable fishing net is larger than the size of the filtering holes on the fixed anti-escape net.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] The present utility model uses a cylindrical captive breeding barrel to breed freshwater fish, which can effectively avoid phenomena such as fish gathering in groups and local oxygen deficiency, improving the breeding effect; after four groups of connecting rings are externally connected with pull ropes, the movable fishing net can be lifted upward, facilitating the fishing and grading of freshwater fish; after the pure oxygen machine works, oxygen can be transported into the oxygenation circular pipe through the connecting air pipe, increasing the oxygen content in the captive breeding barrel. The bubbles generated by oxygenation form a water flow that pushes from the periphery to the center in the captive breeding barrel, promoting the swimming of freshwater fish in the barrel and also pushing breeding wastes such as residual bait and feces to the central part of the captive breeding barrel, facilitating their sedimentation and collection into the water outlet and sewage discharge port at the conical bottom. After the sewage suction pump works, the breeding wastes such as residual bait and feces can be quickly discharged through the sewage pipeline for centralized treatment, realizing the green breeding of freshwater fish and improving the breeding effect.
