Description

Technical Field

[0001] The utility model relates to the technical field of flowing water culture of young and juvenile grouper fish, in particular to a flowing water culture device for young and juvenile grouper fish. Background Art

[0002] Flowing water aquaculture mainly uses continuously flowing water for aquaculture. This method has the characteristics of short aquaculture cycle, small area occupied, high density, high yield, high efficiency and easy management. Flowing water aquaculture continuously renews the water body, so that the farmed fish can grow rapidly under the optimal water temperature, water quality, dissolved oxygen, bait and other conditions. Flowing water aquaculture can be applied to a variety of fish and breeding environments, such as ponds, rivers, lakes, etc. Compared with traditional static breeding, flowing water aquaculture has higher breeding density and faster growth rate, and can also reduce the occurrence of diseases and the use of drugs, and improve breeding efficiency and product quality.

[0003] The breeding of young grouper requires very high water quality, so the water quality needs to be kept clean and stable during the breeding process. Change the water source regularly to avoid water pollution and bacterial growth. Young grouper also has relatively high requirements for breeding density. Too high breeding density will lead to water quality deterioration, disease transmission and other problems, affecting the growth and health of young fish; and young grouper may attack each other during the breeding process. Young grouper may compete for territory in a limited space, especially in breeding boxes or tanks, which may lead to territorial disputes and aggressive behaviors between young fish. When breeding young grouper, reasonably control the stocking density of young fish, so as to improve breeding efficiency and growth quality of young fish.

[0004] The patent with the publication number CN213427824U discloses a flow-through culture device for juvenile grouper, comprising a culture dish, a fixed frame, a partition and a funnel. A U-shaped fixed frame is bolted to the port of the open end of the upper surface of the culture dish, two groups of hollow partitions are bolted between two groups of vertical inner walls of the culture dish, and a rectangular plate-shaped baffle is bolted between the partition and a group of vertical inner walls of the culture dish; a funnel is arranged between the two groups of partitions, and the outer periphery of the funnel is bolted to a group of vertical inner walls of the culture dish through a group of triangular support frames, a water pump is bolted to the center position of the top of the fixed frame, and an L-shaped water guide pipe and a drain pipe are respectively arranged on the left and right sides of the water pump, and a fixing mechanism is arranged at the opposite ends of the water guide pipe and the drain pipe; although the above device solves the problem of filtering impurities in the culture water.

[0005] However, the above technical solution still has the following problems:

[0006] The existing breeding boxes do not separate the growth process of the juveniles of the eastern star fish, which may lead to aggressive behavior between the juveniles of the eastern star fish, causing pollution problems in the breeding boxes. In addition, the juveniles of the eastern star fish grow to different degrees, and the juveniles of the eastern star fish will cannibalize each other, which cannot ensure the growth of the juveniles of the eastern star fish; excessive breeding density will lead to water quality deterioration, disease transmission and other problems, affecting the growth and health of the juveniles of the eastern star fish; and the water filtration system is easy to suck the juveniles of the eastern star fish into it, causing the death of the juveniles of the eastern star fish.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] like Figures 1 to 7As shown, a flow-through culture device for juvenile grouper fish comprises a culture box 1 and a filtering device 4 installed inside the culture box 1, a cross-shaped fixing plate 5 is installed in the middle of the culture box 1, a partition plate device 2 is connected between the cross-shaped fixing plate 5 and the culture box 1, a plurality of conical separators 7 are installed on the outer side of the partition plate device 2, a water pipe 3 is installed on the top of the culture box 1, one end of the water pipe 3 penetrates into the bottom of the culture box 1, and the other end is aligned with the surface of the filtering device 4.

[0026] like Figure 1 As shown, a flow-through culture device for juvenile grouper fish in the utility model is similar in structure to the existing flow-through culture device for juvenile grouper fish, such as the flow-through culture device for juvenile grouper fish disclosed in the patent with publication number CN213427824U. The main improvement of the utility model is that the filter box of the culture box will not suck in juvenile grouper fish, thereby reducing the death of juvenile grouper fish. Figures 1 to 7 As shown, when the water flow culture device for juvenile and young fish of the present invention is used, the cross-shaped fixing plate 5 and the partition plate device 2 divide the culture box 1 into a plurality of culture areas, the water pipe 3 sucks water from one end of the culture box 1 to the top of the filter device 4, and the filter device 4 filters the water and then flows it back into the culture box 1 to complete the water flow cycle. In the initial stage of juvenile and young fish culture, the juvenile and young fish of ... The fry swims from the conical separator 7 to other areas. The opening size of the conical separator 7 is set from small to large according to the arrangement order of the partition plate device 2, so that the fry of the eastern starfish swims to other areas and gradually grows, and cannot swim back to the original area, so as to achieve the effect of separating the fry of the eastern starfish of different sizes, reduce the mutual cannibalism between the fry of the eastern starfish, and when the fry of the eastern starfish is sucked into the water pipe 3, the fry of the eastern starfish can be discharged from the filtering device 4 into the breeding box 1, so as to prevent the fry of the eastern starfish from getting stuck in the filtering device 4 and causing loss.

[0027] like Figures 1 to 4 As shown, a fixing rod 101 is fixedly connected to the middle position of the breeding box 1, a round hole channel 501 slidably connected to the fixing rod 101 is opened on the top of the cross-shaped fixing plate 5, a slot 6 is opened on the outer side of the cross-shaped fixing plate 5, a limit strip 102 is fixedly connected to the inner wall of the breeding box 1, a slot 6 is opened on one side of the limit strip 102, and a partition plate device 2 is slidably connected between two opposite slots 6.
