Description

Technical Field

[0001] The utility model relates to the technical field of spawning and hatching, and more specifically to an spawning and hatching tank for hybrid bream. Background Art

[0002] The body of the hybrid bream is flattened laterally, with a slightly raised back and back of the head. The head is small, the eyes are large, the snout is pointed, the mouth is subsuperior, the mouth cleft is oblique, and the lower jaw is prominent and slightly longer than the upper jaw. The lateral line is complete and slightly curved. The ventral ridge runs from the base of the pectoral or pelvic fins to the anus. The pectoral fins are not as long as or slightly longer than the base of the pelvic fins. The caudal fin is deeply forked, and the upper and lower lobes are equal in length. The body color is gray-blue on the back and silvery white on the sides and abdomen.

[0003] At present, during the incubation period of the fish eggs produced by the hybrid bream, the quality of the fish eggs varies. For example, during the incubation, the bad eggs are in continuous contact with the good eggs, which will subsequently cause the good eggs to be affected and thus die. Moreover, after the fry are hatched, the parent fish may swallow the eggs, which further reduces the survival rate of the hatched eggs. Therefore, this scheme proposes a spawning incubation tank for hybrid bream. Utility Model Content

[0034] Please refer to Figures 1-3 , a spawning and hatching tank for hybrid Megalobrama skolkovii and Culter alburnus, comprising a hatching tank body 1. Between the inner walls of the hatching tank body 1, a bearing plate 2, a support frame 3, and a connecting plate 4 are successively installed from bottom to top. The connecting plate 4 is located above the support frame 3, and a plurality of uniformly distributed fish egg feeding pipes 5 are embedded and installed at the upper end of the connecting plate 4. Two symmetrically distributed automatic feeding assemblies 6 are provided at the upper end of the connecting plate 4. A through hole one 7 is opened at the central end above the connecting plate 4, and a filter screen one 8 is fixedly connected between the inner walls of the through hole one 7. A drain hole 9 is opened at the side end of the hatching tank body 1, and the drain hole 9 is located below the bearing plate 2. A water pump 10 is installed at the outer end of the hatching tank body 1, and a heater is also installed on the inner wall of the 1.

[0035] During the use of this solution, in order to further improve the survival rate of hybrid culter alburnus after spawning in the prior art, in this embodiment, first, water added with methylene blue solution is injected into the incubation tank body 1, and then the fish eggs to be incubated are separated one by one through the fish egg feeding pipeline 5, so that the single fish eggs can fall along the fish egg feeding pipeline 5 above the bearing plate 2, and the fish eggs do not contact each other, avoiding the transmission of bacteria and viruses from the bad eggs in the fish eggs to the good fish eggs, reducing the phenomenon of a large number of deaths of the hatched fish eggs due to the influence of bad eggs, and increasing the survival rate of the fish eggs;

[0036] Meanwhile, under the action of the automatic feeding component 6 and the first filter screen 8, when the fish eggs hatch, the automatic feeding component 6 releases powder feed to the outside regularly, so that the hatched fry can swim through the first filter screen 8 to the upper side of the connecting plate 4 in the area between the bearing plate 2 and the connecting plate 4, and then swallow the powder feed. After a certain period of time, when the volume of the fry increases, due to the increase in body size, the fry cannot return to the area between the bearing plate 2 and the connecting plate 4, thus protecting the fish eggs to be put in later or the unhatched fish eggs, greatly avoiding the phenomenon of adult fish preying on fish eggs or swallowing bad eggs, and further increasing the survival rate of fish egg hatching;

[0037] And under the action of the water body added with methylene blue solution and the heater, the water temperature can be continuously maintained between 20°C and 30°C, avoiding the phenomenon of water mold in the water body and at the same time accelerating the hatching efficiency of the fish eggs;

[0038] Finally, the staff can regularly replace the water body inside the incubation tank body 1 under the action of the water pump 10 to prevent the deterioration of water quality from affecting the hatching rate of the fish eggs.

[0039] Please refer to Figures 1-2 , two symmetrically distributed placement grooves 21 are opened at the upper end of the bearing plate 2, a through hole two 22 is opened at the central end on the upper side of the bearing plate 2, and a second filter screen 23 is fixedly connected between the inner walls of the through hole two 22, and the aperture of the second filter screen 23 is smaller than the aperture of the first filter screen 8.

[0040] During the use of this solution, after the staff inputs the fish eggs into the fish egg feeding pipeline 5 one by one, the fish eggs fall along the fish egg feeding pipeline 5 above the bearing plate 2. Among them, the multiple intersecting interfaces opened in the placement groove 21 are located below the fish egg feeding pipeline 5, so that the falling fish eggs can be separately located between the intersections of each placement groove 21, avoiding the mutual contact of the fish eggs. At the same time, during the subsequent water change by the staff, the water body can flow into the drain hole 9 through the through hole two 22, and due to the limitation of the second filter screen 23, the hatched fry are not easy to flow to the bottom of the incubation tank body 1.

[0041] Please refer to Figures 1-3, the automatic feeding assembly 6 includes a feeding cylinder 61 fixedly connected to the upper end of the connecting plate 4. A plug cover 62 is threadedly connected to the upper end of the feeding cylinder 61. A material discharge hole 63 is formed in the side end of the feeding cylinder 61. A material blocking plate 64 is fixedly connected between the inner walls of the feeding cylinder 61. Two symmetrically distributed material falling holes 65 are formed in the side end of the material blocking plate 64. A motor 66 is installed at the inner bottom end of the feeding cylinder 61. The outer end of the motor 66 is electrically connected to a timing device. The output end of the motor 66 is fixedly connected to a material distributing table 67. Four evenly distributed material placing bins 68 are formed in the side end of the material distributing table 67.

[0042] More specifically: the top end of the material placing bin 68 corresponds to the material falling hole 65, and the material distributing table 67 is attached to the lower side of the material blocking plate 64. The side end of the material placing bin 68 corresponds to the material discharge hole 63, and the bottom end is on the same horizontal plane as it.

[0043] During the use of this solution, personnel can put a large amount of powdered feed above the material blocking plate 64. In the initial stage, part of the powdered feed falls into the two side material placing bins 68 among them. With the time of the timing device preset by the personnel in advance, it can prompt the motor 66 to drive regularly after the fry hatching is over. As a result, each time the material distributing table 67 receives the drive of the motor 66, it rotates 90°. It makes the material placing bin 68 filled with powdered feed rotate to one side of the material discharge hole 63, and then releases it into the water body for the fry to swallow;

[0044] At this time, the material placing bin 68 where the powdered feed on one side of the material discharge hole 63 has been released rotates to the lower side of the material falling hole 65. During its rotation, the material distributing table 67 blocks the powdered feed on the top to prevent the powdered feed from continuously falling. When the material placing bin 68 on one side of the material discharge hole 63 slowly rotates to the lower side of the material falling hole 65, due to the notch above the material placing bin 68, the powdered feed above the material blocking plate 64 continuously falls again to fill the material placing bin 68 for the next work of feeding the water body regularly and quantitatively;

[0045] Thus, it can be realized that the hatching tank can realize the automatic timed and quantitative feeding of powdered feed, reduce the labor burden of continuous care by personnel, and in the follow-up, personnel only need to supplement the powdered feed regularly and replace the water body.

[0046] Please refer to Figure 3 , a transmission shaft 641 is rotatably connected to the upper end of the material blocking plate 64. One end of the transmission shaft 641 penetrates to the lower side of the material blocking plate 64 and is fixedly connected to the central end of the material distributing table 67. A sweeping plate 642 is fixedly connected to the side end of the transmission shaft 641.

[0047] During the use of this solution, while the material distribution table 67 is rotating, the sweeping plate 642 can simultaneously scrape the powder feed on the surface of the material blocking plate 64, so as to more efficiently put the powder feed into the material placing bin 68, and also reduce the retention and waste of part of the powder feed above the material blocking plate 64.

[0048] The above-described embodiments only represent certain implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
