Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, and more specifically to a fish egg collecting device. Background Art

[0002] Collecting fish eggs is an important part of artificial fish breeding. Most artificially bred fish will ovulate after artificial induction of spawning, either spontaneously or artificially. In production, the collection of fish eggs (fry) of such self-ovulating or ovoviviparous fish usually adopts the method of spawning in the original pond, removing the broodstock or collecting in cages. However, spawning in the original pond will cause confusion among the offspring, and cannot meet the needs of isolating the offspring separately (such as establishing a family lineage, etc.); and cage isolation collection, in addition to occupying equipment and cumbersome processes, often limits the range of activities of the broodstock during the ovulation period, which is not suitable for some fish that have special requirements for spawning in a fixed location or environment.

[0003] At present, the collection of fish eggs is very time-consuming and laborious. The commonly used fish egg collection devices generally waste manpower, material resources and financial resources, and are mostly collected manually, which is easy to affect the parent fish, and it is also easy to cause omissions due to the adsorption of fish eggs on other objects in the water, thus causing waste or inconvenience to the later work. For this reason, this scheme proposes a fish egg collection device. Utility Model Content

[0004] 1. Technical problems to be solved:

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a fish egg collection device, which releases simulated water plants made of artificial woven fiber materials into water bodies in multiple areas, and utilizes the phototaxis of fish and the fact that fish like to ovulate on plant leaves, thereby prompting fish to actively ovulate on the released simulated water plants. Finally, personnel only need to determine the location of the simulated water plants for collecting fish eggs based on the floating components on the water surface, and then they can be salvaged one by one, which greatly improves the work of personnel in collecting fish eggs.

[0006] 2. Technical solution:

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A fish egg collecting device comprises a connecting net, a plurality of fish egg collecting pieces are fixedly connected to the lower end of the connecting net, a cable is installed through the central end of the connecting net, a sinking component is installed at the lower end of the cable, and a suspension component is installed at the upper end of the cable.

[0009] A further improvement is that the fish egg collecting piece is simulated water grass made of artificial woven fiber material.

[0010] A further improvement is that the sinking assembly includes an upper cover fixedly connected to the lower end of the cable, the lower end of the upper cover is threadedly connected to the bottom shell, a connecting plate 1 is fixedly connected between the inner walls of the bottom shell, a heavy block is embedded in the bottom of the bottom shell, a lighting lamp is installed on the upper end of the connecting plate 1, and the upper cover is set with a transparent material.

[0011] A further improvement is that the suspension component includes a floating base fixedly connected to the upper end of the cable, a connecting plate 2 is fixedly connected between the inner walls of the floating base, a floating support is embedded and installed at the bottom of the floating base, a floating top cover is threadedly connected to the upper end of the floating base, and a power supply component is provided on the upper side of the connecting plate 2.

[0012] A further improvement is that the power supply assembly includes a solar controller, a battery, and an inverter installed on the upper end of the connecting plate 2, and a solar panel is embedded in the upper end of the floating top cover. The solar controller, solar panel, battery, inverter and lighting are electrically connected through cables.

[0013] A further improvement is that a plurality of egg-laying matrices are provided at the upper end of the connecting net.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0016] The utility model has a reasonable design. The simulated water grass made of artificial woven fiber material is placed in water bodies of various ranges, and the phototaxis of fish and the characteristic that fish like to ovulate on plant leaves are utilized to prompt fish groups to actively ovulate on the placed simulated water grass. At the same time, since the simulated water grass is inedible and has no fragrant grass smell, fish groups are not likely to appear under the edible water grass to swallow the attached fish eggs, thereby avoiding the loss of fish eggs. In addition, since the simulated water grass can be freely placed in the water body, it is not easy to limit the activity range of parent fish during the ovulation period. Finally, personnel only need to determine the position of the simulated water grass for collecting fish eggs according to the floating suspension components on the water surface, and then salvage them one by one, thereby greatly improving the collection of fish eggs by personnel.

[0017] When in use, the sinking component acts as a load-bearing object and a bright object, which can drive the fish egg collecting component connected to the connecting net to sink into the water and release bright light, using the phototaxis of fish to attract fish schools so that the fish schools can lay eggs on the surface of the fish egg collecting component, which is conducive to subsequent unified collection. The suspension component floats to the water surface to remind personnel of the location of the simulated water plants after collecting fish eggs, and at the same time uses light energy conversion to provide kinetic energy for the light of the sinking component.

[0018] It should be noted that the structures not introduced in the present invention are not related to the design points and improvement directions of the present invention, and are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0031] More specifically, the fish egg collecting member 2 is a simulated waterweed made of artificial woven fiber material.

[0032] During the use of this scheme, in order to avoid the time-consuming and laborious work of the existing personnel in collecting fish eggs, and the work steps of consuming a lot of time to fish, in this embodiment, by putting the simulated water grass made of artificial woven fiber material into water bodies in multiple ranges, and utilizing the phototaxis of fish and the characteristics that fish like to ovulate on plant leaves, the fish school is prompted to actively ovulate on the put-in simulated water grass, and at the same time, since the simulated water grass is inedible and has no fragrant grass smell, the fish school is not easy to appear under the edible water grass to swallow the attached fish eggs, thereby avoiding the loss of fish eggs, and since the simulated water grass can be freely put into the water body, it is not easy to limit the activity range of the parent fish during the ovulation period. Finally, the personnel only need to determine the location of the simulated water grass for collecting fish eggs according to the floating suspension component 6 on the water surface, and then salvage them one by one, which greatly improves the personnel's work of collecting fish eggs;

[0033] When in use, the sinking component 5 acts as a load-bearing object and a bright object, which can drive the fish egg collecting component 2 connected to the connecting net 1 to sink into the water and release bright light, thereby utilizing the phototaxis of fish to attract fish schools so that the fish schools can lay eggs on the surface of the fish egg collecting component 2, which is conducive to subsequent unified collection. The suspension component 6 floats to the water surface to remind personnel of the position of the simulated water plants after collecting the fish eggs, and at the same time utilizes light energy conversion to provide kinetic energy for the light of the sinking component 5.
