Problems solved by technology

It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. With the increase of aquaculture production, the proportion in the aquaculture industry is also increasing. Before aquaculture, fertilized eggs need to be hatched and raised. However, in the traditional hatching process of aquatic animals, it is easy to be damaged by the legs and tentacles of river shrimp, which will damage the fertilized eggs and seedlings and reduce the survival rate of hatching

Embodiment 1

[0036] Such as Figure 1-Figure 5 As shown, a fertilized egg incubator for aquatic animals that prevents shrimps from biting in natural waters includes a frame body 1, a frame cover 15, and handrails 20. The lower longitudinal beam 8 is arranged on the side, the lower crossbeam 7 is arranged on one side of the lower The lower end of the beam 8 is provided with a bottom outer mesh 12, which is used as the bottom mesh of the frame main body 1, the bottom inner mesh 9 is arranged above the bottom outer mesh 12, and the second side outer mesh 6 is arranged on both sides of the bottom outer mesh 12. The second side outer mesh 6 inner side is provided with the second side inner mesh 11, the bottom outer mesh 12 front and rear sides are provided with the first side outer mesh 10, and the first side outer mesh 10 inner side is provided with the first side inner mesh. Partition net 5, second side outer partition net 6, first side outer partition net 10 are provided with upper layer pa...

Embodiment 2

[0038] The difference between this embodiment and embodiment 1 is:

[0039] The upper beam 4 and the lower beam 7 are provided with a hook 21 outside, and the hook 21 is connected with the upper beam 4 and the lower beam 7 by welding. The net 10, the second side internal partition 11, the bottom internal partition 9, the bottom external partition 12, the upper partition 13 and the frame main body 1 are connected by rivets, and the hook 21 is convenient for placing the incubator in water. The connection strength of 21, the rivet connection makes the first side inner mesh 5, the second side outer mesh 6, the first side outer mesh 10, the second side inner mesh 11, the bottom inner mesh 9, the bottom outer mesh 12. The connection between the upper layer spacer 13 and the frame main body 1 is firm.

[0040] Working principle: Suspend the incubator in the water through the hook 21, the second side outer mesh 6, the second side inner mesh 11, the first side outer mesh 10, the first...

Abstract

The invention discloses an aquatic animal fertilized ovum incubator for preventing shrimp bites in a natural water area. The aquatic animal fertilized ovum incubator comprises a frame main body, a frame cover and armrests, wherein the frame main body comprises upright posts; a lower longitudinal beam is arranged on the lower side between the upright posts; a lower transverse beam is arranged on one side of the lower longitudinal beam; an upper longitudinal beam is arranged above the lower longitudinal beam; an upper transverse beam is arranged on one side of the upper longitudinal beam; bottomexterior separation nets are arranged at the lower ends of the lower transverse beam and the lower longitudinal beam; bottom interior separation nets are arranged above the bottom exterior separationnets; and second side face exterior separation nets are arranged on two sides of the bottom exterior separation nets. The aquatic animal fertilized ovum incubator disclosed by the invention has the beneficial effects that double-layer nylon cloth is adopted at the bottom, the shrimp feet and tentacles cannot be contact with fertilized eggs and fries so as not to cause damage in the incubation process, the death rate in the incubation process is reduced, the incubating survival rate is improved, the degree of automation is high, oxygenation is performed in the incubator, and dissolved oxygen requirements in the incubation process are met.

Description

technical field [0001] The invention relates to the field of aquatic animal breeding equipment, in particular to an aquatic animal fertilized egg incubator that prevents shrimps from biting in natural waters. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. With the increase of aquaculture production, the proportion in the aquaculture industry is also increasing. Before aquaculture, fertilized eggs need to be hatched and raised. However, in the traditional hatching process of aquatic animals, it is easy to be damaged by the feet and antennae of river prawns, which will damage the fertilized eggs and seedlings and reduce the survival rate of hatching. Contents of the invention [0003] The object of the present invention is to provide a kind of inc...
