AI Technical Summary
In the prior art, the fertilized eggs of the Otaki six-line fish are susceptible to insufficient oxygen supply caused by poor water flow during hatching, contamination of precipitates and mechanical damage, which affects the hatching rate, and it is difficult to separate and collect the fertile fish after hatching.
A fertilized egg hatching and fish collection device including long strips, short rods and suspended ropes is designed. By hanging the fertilized eggs in the water inside the breeding barrel for hatching, it ensures that the fertilized eggs are in full contact with the surrounding water flow, avoid contact with the bottom of the pond, improve oxygen supply and hatching rate, and facilitate separation and collection of fish.
Through suspended hatching, the hatching rate of fertilized eggs of Datae six-line fish is significantly improved, avoiding sediment pollution and mechanical damage. At the same time, the hatched fish are naturally separated, which is convenient for efficient collection.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of Hexagrammos otakii farming, and particularly relates to a device for hatching fertilized eggs and collecting larvae suitable for Hexagrammos otakii farming. Background Art
[0002] Hexagrammos otakii is an important cultured fish, which has received wide attention because of its delicious meat and high nutritional value. In the process of Hexagrammos otakii farming, the hatching of fertilized eggs and the collection of larvae are key links. At present, the common hatching method is to place the fertilized eggs in a net cage or an incubation pond.
[0003] However, the fertilized eggs in these traditional net cages or incubation ponds are easily affected by poor water flow, resulting in insufficient oxygen supply, which affects the normal development of the fertilized eggs. The fertilized eggs are in direct contact with the pond bottom, and are easily contaminated by sediment and mechanically damaged, affecting the hatching rate. At the same time, the hatched larvae are often mixed with the fertilized eggs, making it difficult to separate and collect them centrally. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a device for hatching fertilized eggs and collecting larvae suitable for Hexagrammos otakii farming, which can improve the hatching rate of Hexagrammos otakii fertilized eggs and facilitate the collection of larvae.
[0005] The technical solution adopted by the utility model is specifically as follows:
[0006] A device for hatching fertilized eggs and collecting larvae suitable for Hexagrammos otakii farming includes a long strip board. A plurality of connecting short rods arranged along the long side direction of the long strip board are fixedly connected to the upper side of the long strip board, and suspension ropes are connected to the outer sides of the plurality of connecting short rods.
[0007] The technical effect achieved by the utility model is:
[0008] The device for hatching fertilized eggs and collecting larvae suitable for Hexagrammos otakii farming of the utility model hatches the fertilized eggs of Hexagrammos otakii by hanging them in the water inside the breeding bucket through a long strip board that can be placed on the breeding bucket, enabling the fertilized eggs of Hexagrammos otakii to better contact the water flow around them, so that the water flow around the fertilized eggs of Hexagrammos otakii can provide sufficient oxygen to the fertilized eggs of Hexagrammos otakii, promoting the normal development of the fertilized eggs. Moreover, the fertilized eggs of Hexagrammos otakii suspended in the water do not contact the bottom of the breeding bucket, reducing the pollution and mechanical damage of the sediment to the fertilized eggs of Hexagrammos otakii, improving the hatching rate of the fertilized eggs of Hexagrammos otakii. And the hatched larvae formed by the suspended fertilized eggs of Hexagrammos otakii will naturally fall into the water and separate from the fertilized eggs of Hexagrammos otakii, making it more convenient and efficient to collect the larvae. Description of the Drawings
[0009] Figure 1It is a schematic diagram of the overall structure of the present utility model;
[0010] Figure 2 It is a schematic diagram of the partial structure of the present utility model.
[0011] In the attached drawings, the list of components represented by each reference numeral is as follows:
[0012] 1. Long strip board; 2. Connecting short rod; 3. Suspension rope; 4. Eggs of Hexagrammos otakii; 5. Cultivation barrel. Specific embodiments
[0013] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.
[0014] As Figure 1 - Figure 2 shown, a device for hatching fertilized eggs and collecting larvae suitable for the cultivation of Hexagrammos otakii includes a long strip board 1. A plurality of connecting short rods 2 arranged at equal intervals along the long side direction of the long strip board 1 are fixedly connected to the upper side of the long strip board 1. Suspension ropes 3 are connected to the outside of the plurality of connecting short rods 2, and the connection method can be socket connection. The lower ends of the plurality of suspension ropes 3 can be provided with eggs of Hexagrammos otakii 4, so that the eggs of Hexagrammos otakii 4 can be suspended in the water inside the cultivation barrel 5 by the suspension ropes 3 for hatching, enabling the eggs of Hexagrammos otakii 4 to better contact the water flow on its periphery, so that the water flow on the periphery of the eggs of Hexagrammos otakii 4 can provide sufficient oxygen to the eggs of Hexagrammos otakii 4, promoting the normal development of the fertilized eggs. Moreover, the eggs of Hexagrammos otakii 4 suspended in the water do not contact the bottom of the cultivation barrel 5, reducing the pollution and mechanical damage of the sediment to the eggs of Hexagrammos otakii 4, improving the hatching rate of the eggs of Hexagrammos otakii 4. And the larvae formed after the eggs of Hexagrammos otakii 4 suspended in the water hatch will naturally fall into the water and separate from the eggs of Hexagrammos otakii 4, which makes it more convenient and efficient to collect the larvae.
[0015] The working principle of the present utility model is as follows: Place multiple rows of long strip plates 1 on the upper end of the breeding barrel 5, and make the U-shaped clamp able to be clamped at the edge of the upper end of the breeding barrel 5. Then, sleeve the suspension rope 3 on the connecting short rod 2, and the fertilized eggs 4 of Hexagrammos otakii on the suspension rope 3 can be suspended in the water inside the breeding barrel 5 for hatching, enabling the fertilized eggs 4 of Hexagrammos otakii to better contact the water flow on its periphery, so that the water flow on the periphery of the fertilized eggs 4 of Hexagrammos otakii can provide sufficient oxygen to the fertilized eggs 4 of Hexagrammos otakii, promoting the normal development of the fertilized eggs. Moreover, the fertilized eggs 4 of Hexagrammos otakii suspended in the water do not contact the bottom of the breeding barrel 5, reducing the pollution and mechanical damage of the sediment to the fertilized eggs 4 of Hexagrammos otakii, improving the hatching rate of the fertilized eggs 4 of Hexagrammos otakii. And the larvae formed after the hatching of the suspended fertilized eggs 4 of Hexagrammos otakii will naturally scatter into the water and separate from the fertilized eggs 4 of Hexagrammos otakii, which makes it more convenient and efficient to collect the larvae.
[0016] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
