Problems solved by technology

[0002] Spring is the gonadal development stage of fish, and the food intake increases. When the fish develops to the sexually mature stage and becomes broodstock, in the artificial fry breeding work, the broodstock is usually artificially paired and placed in the breeding pond for natural reproduction, and then the broodstock is removed and collected by pulling a net Fry, broodstock may prey on fry or roe in the natural breeding process, and the swimming of broodstock has a certain impact on the survival rate of fry or roe, the traditional artificial fry breeding method needs to be further improved

Embodiment 1

[0012] like figure 1 , 2 As shown, the fish fry separation equipment includes a casing 5, a separation net 2 arranged in the middle of the casing 5, a baffle 1 is provided on the surface of the casing 5, a support plate 9 is provided above the baffle plate 1, and the bottom surface of the support plate 9 is evenly distributed with electromagnetism. Iron 10, a sweeper 11 is placed in the space between the baffle plate 1 and the separation net 2, the bottom of the box body 5 is provided with a collection net 3, the bottom surface of the box body 5 is evenly distributed with gas heads 4, the supporting plate 9 adopted is made of iron, and the baffle plate 1 is made of rubber or plastic, and the internal surface area of ​​the baffle 1, the separation net 2, the collection net 3 and the box body 5 are the same, and the eggs or fry produced by the broodstock are effectively separated directly to the collection net 3 through the separation net 2 On the surface, the number of eggs la...

Embodiment 2

[0017] like figure 1 , 2 As shown, the sweeper 11 includes a floating block 11c, two support rods 11e and uniformly distributed sponge strips 11d are arranged below the floating block 11c, an iron block 11b is connected above the floating block 11c, and the cross section of the support rods 11e is larger than the net of the separation net 2 The purpose is to effectively support the cleaner 11 and the magnet 10 of the cleaner 11 is attracted and driven by its magnetic force, so that the cleaner 11 moves in the space where the parent fish is placed, and the sponge strip 11d is used to clean or absorb large particle pollutants in the space where the parent fish is placed When the sponge bar 11d passes or is passed by the parent fish, the body surface of the parent fish can be cleaned, which is beneficial to keep the water quality clean and effectively prevent the parent fish from being infected and sick during the breeding period, and when the cleaner 11 is driven by the electrom...

Embodiment 3

[0020]The wear-resistant coating 11a is formed by curing the wear-resistant coating on the surface of the iron block 11b to form the wear-resistant coating 11a. The wear-resistant coating is composed of the following components and parts by weight: 32 parts of polyester modified acrylic resin, 7 parts of titanium dioxide, 12 parts of iron powder, 6 parts of fluoroolefin resin, 6 parts of superfine aluminum silicate, 0.04 parts of L-(+)-2,3-dihydroxypropionic acid, L-(-)-2,3-dihydroxypropionic acid 0.001 parts, 0.03 parts of regulator, 10 parts of bentonite, 17 parts of curing agent, 34 parts of graphite powder, 22 parts of toluene, 7 parts of water, the curing agent is a mixture of polyamide curing agent and m-phenylenediamine curing agent, wear-resistant coating During the preparation process, carbon dioxide gas was passed through for 20 minutes, and it was prepared in an oscillator containing diamond. The prepared wear-resistant coating can be cured naturally at room tempera...

Abstract

The invention discloses a fish fry separating device, and belongs to the technical field of breeding devices. The fish fry separating device comprises a box body, a separation net arranged in the middle of the box body, a baffle plate which is arranged on the surface of the box body, a supporting plate which is arranged above the baffle, electromagnets which are uniformly distributed on the bottomsurface of the supporting plate, a sweeper which is arranged in the space between the baffle and the separation net, a collecting net which is arranged at the bottom of the box body, and air heads which are uniformly distributed at the bottom surface of the box body. According to the fish fry collecting device disclosed by the invention, the separated fish eggs collecting can be used for hatching, the situations that the parent fish sex gland is mature and fish is difficult to produce can be effectively avoided, and the parent fishes can be subjected to cleaning treatment.

Description

technical field [0001] The invention belongs to the technical field of breeding devices, and in particular relates to fry separation equipment. Background technique [0002] Spring is the gonadal development stage of fish, and the food intake increases. When the fish develops to the sexually mature stage and becomes broodstock, in the artificial fry breeding work, the broodstock is usually artificially paired and placed in the breeding pond for natural reproduction, and then the broodstock is removed and collected by pulling a net Fry, broodstock may prey on fry or roe in the natural breeding process, and the swimming of broodstock has a certain impact on the survival rate of fry or roe, and the traditional artificial fry cultivation method needs to be further improved. Contents of the invention [0003] The object of the present invention is to provide a fry separation device that collects fish roe in a separate manner for hatching, effectively avoids parent fish gland ma...
