Description

Technical Field

[0001] The utility model relates to the technical field of fish fry hatching, in particular to a circulating water hatching device for giant spiny loach. Background Art

[0002] The giant spiny loach (Mastacembelusarmatus) belongs to the class of ray-finned fish, the order of Synbranchidae, the family of Acanthopsidae, and the genus Acanthopsidae. It is commonly known as: Naconi, Shiconi, Pig Saw, Chili Fish, and Swordfish. It is mainly distributed in the water systems of Fujian, Jiangxi, Guangdong, Guangxi, Hunan and other places south of the Yangtze River.

[0003] The fertilized eggs of the giant spiny loach are sticky eggs, which are prone to caking and mold infection during the incubation process. The fertilized eggs of the giant spiny loach have a high oil content. In the late incubation period, a large amount of oil will be released when the membrane breaks. At the same time, high-protein substances are also produced when the bad eggs dissolve. Oil and high-protein substances will cause the incubation water quality to deteriorate, making it difficult to control the incubation water quality of the fertilized eggs, which seriously affects the incubation of normal embryos.

[0004] In addition, the incubation period of fertilized eggs of giant spiny loach is relatively long and requires stable incubation conditions. The open incubation method makes it difficult to control the stability of water quality. The incubation effect is often affected by climate change or climatic problems such as rainstorms and flash floods, resulting in low efficiency of artificial breeding, which is not conducive to the large-scale development of the industry.

DETAILED DESCRIPTION

[0027] See also Figures 1 to 4 The utility model provides a circulating water hatching device for giant spiny loach, comprising a tank body 1, an overflow pipe 4 and a purification tank 5. A first partition 2 and a second partition 3 are arranged inside the tank body 1. The first partition 2 and the second partition 3 divide the inside of the tank body 1 into a water storage tank 101, a hatching tank 102 and a seedling collection tank 103. The first partition 2 is arranged between the water storage tank 101 and the hatching tank 102, and the second partition 3 is arranged between the hatching tank 102 and the seedling collection tank 103. The height of the first partition 2 is higher than the height of the second partition 3. For example, the height of the first partition 2 is 55 cm, and the height of the second partition 3 is 50 cm. The water in the water reservoir 101 overflows from the top of the first partition 2 to the hatching pool 102, and the water in the hatching pool 102 overflows from the top of the second partition 3 to the seedling collection pool 103; the hatching pool 102 is detachably connected with a fertilized egg adhesion tray 6, each fertilized egg adhesion tray 6 is obliquely inserted into the hatching pool 102, and the inner wall of the hatching pool 102 is provided with a plurality of card slots 20, and the fertilized egg adhesion tray 6 is inserted into the card slot 20. The entire fertilized egg adhesion tray 6 is immersed in the hatching pool 102, and the upper edge of the fertilized egg adhesion tray 6 is 2-3cm away from the top of the second partition 3; the fertilized egg adhesion tray 6 is composed of a frame and a mesh covering the frame, and the mesh is a 40-mesh polyethylene net. The fertilized eggs of the giant loach are uniformly adhered to the fertilized egg adhesion tray 6.

[0028] The seedling collecting pool 103 is provided with a seedling collecting net bag 7, which is connected to the second partition plate 3; the fry that break the membrane enters the seedling collecting net bag 7 from the hatching pool 102 along the flow direction of the water flow in the hatching pool 102.

[0029] The overflow pipe 4 is arranged in the seedling collecting pool 103, and the overflow pipe 4 is composed of a longitudinal pipe 401 and a transverse pipe 402. The transverse pipe 402 is arranged at the upper end of the longitudinal pipe 401, and the transverse pipe 402 is arranged at a position close to the top of the second partition plate 3, so that there is sufficient water in the seedling collecting pool 103 to meet the survival of the fry. The left and right ends of the transverse pipe 402 are covered with a 40-mesh stainless steel mesh to ensure that the water on the surface of the seedling collecting pool 103 can enter the longitudinal pipe 401 from the transverse pipe 402 in real time.

[0030] The lower end of the longitudinal pipe 401 passes through the bottom wall of the seedling collection pool 103 and extends to the outside of the seedling collection pool 103, and the lower end of the longitudinal pipe 401 is connected to the third pipe 26; the third pipe 26 is connected to the purification pool 5, and the third pipe 26 is provided with a second valve 12, and the longitudinal pipe 401 is also connected to the fourth pipe 27, and the fourth pipe 27 is provided with a third valve 13; the purification pool 5 is provided with a water pump 15, and the water pump 15 injects the water in the purification pool 5 into the water storage tank 101 through the first pipe 16. The first pipe 16 is provided with a first valve 22.

[0031] Before the fertilized egg ruptures its membrane, the second valve 12 remains in an open state and the third valve 13 remains in a closed state; the hatching water enters the purification tank 5 from the seedling collection tank 103 and is then pumped to the water storage tank 101 by the water pump 15 .

[0032] In the early stage when the fertilized egg begins to break the membrane (the fertilized egg begins to break the membrane, and the membrane breaking rate is less than 5%), the second valve 12 remains in the open state, and the opening of the third valve 13 is opened to one-third. At this time, the water overflowing from the seedling collection pool 103, the grease and high-protein substances produced after the fry membrane breaks can flow to the purification pool 5 through the third pipeline 26, and the remaining part is discharged from the hatching device through the fourth pipeline 27.

[0033] When a large number of fry break out of the membrane (the membrane breaking rate is greater than or equal to 5%), the water quality turns white, and a large amount of grease appears on the water surface, the second valve 12 remains closed, and the third valve 13 is fully opened, and the water overflowing from the seedling collection pool 103 is completely discharged from the hatching device to ensure that the water quality in the hatching pool is stable.

[0034] Specifically, a third partition 8 is provided in the purification pool 5, and the third partition 8 divides the interior of the purification pool 5 from left to right into a heating pool 9 and a water treatment pool 10. The water pump 15 is provided in the heating pool 9, and the water pump 15 injects the water in the heating pool 9 into the water reservoir 101 through the first pipe 16. The water in the water treatment pool 10 overflows from the top of the third partition 8 into the heating pool 9. A water treatment system 11 is provided in the water treatment pool 10, and the second valve 12 is connected to the water treatment system 11.

[0035] The heating pool 9 is also provided with a heating rod 14, which controls the water temperature of the heating pool 9 to be constant, so that the water temperature of the incubator is maintained at 28-30°C. The heating pool 9 is also connected to a second pipe 17 connected to an external water source, and a fourth valve 23 is provided at the front end of the second pipe 17. The end of the second pipe 17 is immersed in the liquid surface of the heating pool 9, and the end of the second pipe 17 is connected to a water level control valve 24. The water level control valve 24 is specifically a float control valve; the float control valve can replenish the water source according to the height of the water level in the heating pool 9 to ensure the stability of the system water level.

[0036] Specifically, the water treatment system 11 includes a filter device 1101, an ultraviolet sterilization lamp 1102, two groups of activated carbon adsorption units 1103, a fourth partition 1104 and a fifth partition 1105. The filter device 1101 is arranged on the side of the top of the water treatment pool 10 close to the longitudinal tube 401, and the filter device 1101 is connected to the third pipeline 26; the water overflowing from the seedling collection pool 103 to the water treatment system 11 is first filtered by the filter device 1101, then sterilized by the ultraviolet sterilization lamp 1102, enters the two activated carbon adsorption pools 1002, and finally flows into the heating pool 9 by overflow.

[0037] The fourth partition 1104 and the fifth partition 1105 are erected in the water treatment pool 10, and the fourth partition 1104 and the fifth partition 1105 divide the water treatment pool 10 into an ultraviolet sterilization pool 1001 and two activated carbon adsorption pools 1002 from right to left, and the ultraviolet sterilization pool 1001 is located below the filtering device 1101, the ultraviolet sterilization lamp 1102 is arranged in the ultraviolet sterilization pool 1001, and the two groups of activated carbon adsorption units 1103 are respectively arranged in the two In the activated carbon adsorption pool 1002, the bottom of the fourth partition 1104 is in contact with the bottom of the water treatment pool 10, and the water in the ultraviolet disinfection pool 1001 overflows from the top of the fourth partition 1104 into the activated carbon adsorption pool 1002. A channel 25 is left between the bottom of the fifth partition 1105 and the bottom of the water treatment pool 10, so that the bottoms of the two activated carbon adsorption pools 1002 are connected, and the water in the activated carbon adsorption pool 1002 overflows from the top of the third partition 8 into the heating pool 9.

[0038] The water in the ultraviolet disinfection pool 1001 enters the activated carbon adsorption pool 1002 from above the fourth partition 1104, and the water in the activated carbon adsorption pool 1002 near the heating pool 9 enters the heating pool 9 from above the third partition 8. If the tops of the two activated carbon adsorption pools 1002 are connected but the bottoms are not connected, the water in the activated carbon adsorption pool 1002 will directly enter the heating pool 9 without being adsorbed by the two groups of activated carbon adsorption units 1103. As the incubation time increases, the water quality of the incubation water will gradually deteriorate.

[0039] After the bottoms of the two activated carbon adsorption pools 1002 are connected, the flow process of water between the ultraviolet disinfection pool 1001, the two activated carbon adsorption pools 1002 and the heating pool 9 is as follows:

[0040] For the convenience of description, the activated carbon adsorption pool 1002 near the ultraviolet disinfection pool 1001 is named as the first activated carbon adsorption pool 1002, and the activated carbon adsorption pool 1002 near the heating pool 9 is named as the second activated carbon adsorption pool 1002;

[0041] The water in the ultraviolet disinfection pool 1001 enters the first activated carbon adsorption pool 1002 from above the fourth partition 1104. Since the bottoms of the two activated carbon adsorption pools 1002 are connected, the water in the first activated carbon adsorption pool 1002 can only flow from right to left and from top to bottom, and enter the second activated carbon adsorption pool 1002 after passing through the bottom of the fifth partition 1105 and the channel 25 at the bottom of the water treatment pool 10. Each group of activated carbon adsorption units 1103 includes two groups of first activated carbon units 11031 arranged horizontally and one group of second activated carbon units 11032 arranged vertically, and the second activated carbon unit 11032 is arranged between the two groups of first activated carbon units 11031.

[0042] When the water in the first activated carbon adsorption tank 1002 flows from top to bottom, the water in the first activated carbon adsorption tank 1002 passes through two groups of first activated carbon units 11031 arranged horizontally, so that impurities in the water are adsorbed. When the water in the first activated carbon adsorption tank 1002 flows from right to left, the water in the first activated carbon adsorption tank 1002 passes through the second activated carbon units 11032 arranged vertically, so that impurities in the water are adsorbed.

[0043] The water in the second activated carbon adsorption pool 1002 can only flow from right to left and from bottom to top from the top of the third partition 8 to the heating pool 9. When the water in the second activated carbon adsorption pool 1002 flows from right to left, the water in the second activated carbon adsorption pool 1002 passes through the longitudinally arranged second activated carbon units 11032, so that impurities in the water are adsorbed. When the water in the second activated carbon adsorption pool 1002 flows from bottom to top, the water in the second activated carbon adsorption pool 1002 passes through two groups of transversely arranged first activated carbon units 11031, so that impurities in the water are adsorbed. Therefore, the water in the ultraviolet sterilization pool 1001 overflows from the top of the fourth partition 1104 into the activated carbon adsorption pool 1002, the first activated carbon adsorption pool 1002 and the second activated carbon adsorption pool 1002 are connected at the bottom, and the water in the second activated carbon adsorption pool 1002 overflows from the third partition 8 into the heating pool 9, which can force the water in the water treatment pool 10 to pass through two groups of activated carbon adsorption units 1103 before entering the heating pool 9, thereby avoiding some water from directly entering the heating pool 9 without being treated by the activated carbon adsorption unit 1103, thereby ensuring the stability of the water quality of the incubation device.

[0044] Specifically, the filtering device 1101 includes a box body 11011 made of fiberglass, the third pipe 26 is connected to the upper part of the box body 11011, the lower part of the box body 11011 is connected to the ultraviolet disinfection pool 1001, and the box body 11011 is filled with filter cotton 11012.

[0045] Specifically, the tank body 1, the first partition plate 2 and the second partition plate 3 are made of tempered glass, and the purification tank 5, the third partition plate 8, the fourth partition plate 1104 and the fifth partition plate 1105 are made of glass fiber reinforced plastics.

[0046] Specifically, it also includes an aerator 18 and a nano aeration tube 19, which are arranged around the bottom of the hatching pool 102, and the nano aeration tube 19 is installed below the fertilized egg adhesion plate 6, and the nano aeration tube 19 and the aerator 18 are connected by a conduit. During the entire process of fertilized egg hatching, the aerator 18 remains turned on to ensure the dissolved oxygen demand of the hatching pool 102. When the fertilized eggs begin to break the membrane, the amount of air introduced into the hatching pool 102 by the aerator 18 is increased, driving the water flow at the bottom of the hatching pool 102 to flow upward, so that the fry that break the membrane can smoothly enter the seedling collection net bag 7 of the seedling collection pool 103.

[0047] Specifically, the mesh number of the seedling collecting net bag 7 is 40 meshes.

[0048] Specifically, a support frame 21 is further included, the tank body 1 is arranged above the support frame 21 , and the purification pool 5 is arranged below the support frame 21 .

[0049] A specific application of the present application is: turn on the heating rod 14, the water pump 15 and the aerator 18, open the second valve 12, and close the third valve 13. The heating rod 14 heats the water in the heating pool 9 to maintain the water temperature at 28-30°C.

[0050] Before the fertilized eggs rupture their membranes, the second valve 12 is opened, the third valve 13 is closed, and the water pump 15 transports the water in the heating pool 9 to the water reservoir 101. The water in the water reservoir 101 overflows from the top of the first partition 2 to the hatching pool 102, the water in the hatching pool 102 overflows from the top of the second partition 3 to the seedling collection pool 103, and the water in the seedling collection pool 103 flows into the water treatment pool 10 through the overflow pipe 4. In the water treatment pool 10, the filtration, ultraviolet sterilization and activated carbon adsorption of the water body are completed. The water in the water treatment pool 10 overflows from the top of the third partition 8 to the heating pool 9, and is then transported to the water reservoir 101 by the water pump 15. Before the fertilized eggs of the giant loach rupture their membranes, the water for hatching the fertilized eggs keeps the above-mentioned cycle. The aerator 18 aerates the hatching pool 102 to maintain the oxygen required for the hatching of the fertilized eggs.

[0051] In the early stage when the fertilized eggs begin to break the membrane and produce fry, the second valve 12 remains open, and the third valve 13 is opened, and the opening of the third valve 13 is opened to one-third, so that a part of the water in the overflow pipe 4 is discharged from the fourth pipe 27, so that the grease and high-protein substances produced by the fry membrane breaking can leave the hatching device in time.

[0052] When the fry in the hatching pool 102 begin to rupture their membranes in large numbers, the third valve 13 is fully opened and the second valve 12 is closed. The water overflowing from the seedling collection pool 103 into the overflow pipe 4 no longer flows into the water treatment pool 10, but is completely discharged from the hatching device to ensure stable water quality in the hatching device.

[0053] As the water in the seedling collection pool 103 is discharged from the incubation device, the water level in the heating pool 9 gradually decreases. At this time, the water level control valve 24 automatically allows external water to enter the heating pool 9 according to the water level in the heating pool 9 to ensure the stability of the water level of the entire device.

[0054] From the time when the fry are hatched from the fertilized eggs, the air volume of the aerator 18 is increased to drive the water flow at the bottom of the hatching pool 102 to flow upward, so that the fry that breaks out of the membrane can smoothly cross the second partition 3 and enter the seedling collection net bag 7 in the seedling collection pool 103. And, according to the hatching situation, the fertilized egg adhesion plate 6 is tapped irregularly and gently to make the fry go upstream, escape from the hatching pool 102, and enter the seedling collection net bag 7. And according to the hatching situation, the fry in the seedling collection net bag 7 is regularly transferred to the seedling cultivation pool.

[0055] In the present application, a closed circulating water incubation device is used before the fertilized eggs break the membrane, which reduces the amount of water used for hatching and ensures the stability of the hatching water quality; the real-time separation of hatched fry and bad eggs is achieved, reducing the phenomenon of death caused by fry aggregation and adhesion to moldy eggs; the closed circulating water reduces the difficulty of mold prevention and control, and at the same time, the ultraviolet sterilization method is adopted, which is both environmentally friendly and reduces the impact of drug use on embryonic development; the incubation device solves the problem of deterioration of hatching water quality caused by the production of a large amount of oil when the giant spiny loach fry breaks the membrane; the circulating water system reduces the difficulty of giant spiny loach hatching management and improves the breeding efficiency.

[0056] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention.
