Description
Technical field
Fish production field is the utility model is related to, specifically a kind of catfish spawning net cage.
Background technology
Catfish is a kind of high-quality freshwater fish, containing abundant nutrition, fine and tender taste, the protein contained and fat compared with
It is more, there is preferable dietary function to weak deficient, malnutritive people, catfish mainly lives in rivers, lake, reservoir, swag
Middle lower floor, be hidden in more on littoral area activity, daytime under thick grass, stone or deep water bottom, night foraging activity is frequent, after autumn more
Occupy and survived the winter in deep water or sludge, degree of ingesting also weakens.Predacious fish, prey are mostly small fishes, such as eat bar, crucian carp
Yu, Acenthogobius flavimanus, pseudorasbora parva, carp, loach etc., shrimps and aquatic insect are also eaten, catfish category nocturnal habit animal, are quietly hidden daytime
In the hole of river bed or under tree root, night comes out activity, looked for food, and catfish keeps in dark place, and likes living in the stone gap in waters, dell, tree
In the soil cave or pit hole of the root bottom part and slow waters of flow velocity, reservoir, pond, lake, mill weir hydrostatic in, lie prostrate in the moon more
Dark bottom or sheet of water lettuce, water peanut, below water hyacinth, do not eaten after entering the winter, hide and passed the winter in profundal zone or cave,
If going to invade without what, not moving about typically, catfish is hidden by day and come out at night, very voracious entirely with smell and two pairs of antenna huntings,
Weather is warmmer, and appetite is bigger, and cloudy day and nocturnalism are frequent, catfish early sexual maturity, and a general age is maturation, chases after in groups during spawning
By male catfish is also that the ovum of female catfish production is contained in the mouth, hatches small catfish with this, juvenile fish is with zooplankter, mollusk
For food, wherein the larva of aquatic insect and shrimps are its delicious foods.Supplied to solve the seed in pond and paddy field aquaculture catfish
Problem is answered, artificial propagation catfish, cultivation Technique of Raising Seeedling deploy extensively, and the breeding of traditional catfish uses cement pit, will inject medicine
Parent population after thing is put into spawning pond and waits to produce, and spawning pool area preferably, 0.5 meter or so of the depth of water, is often put down for 5~10 square metres when hastening parturition
Square rice spawning pond puts 1 group of parent population, the fish nest that laying is made with fortune windmillpalm sheath-fibre in spawning pond, fish nest laying density more greatly, so as not to production
Raw excessive landing ovum influences incubation rate, after Gunther parent fish spawning, catches away parent population rapidly, allows embryonated egg to hatch in former pond, also can be by fish
Nest gently picks up, and is placed in net cage and hatches, and because spawning pond is fixedly installed, construction cost is high, and building spawning pond needs to select to close
Suitable address, it is also necessary to which other such as supply water, inflate auxiliary facility, and catfish breeding amount is limited, and it is also inconvenient to breed operation.
The content of the invention
To overcome drawbacks described above, the utility model devises a kind of catfish spawning net cage.
The technical solution of the utility model is a kind of catfish spawning net cage, it is characterized in that, spawning net cage is double-deck cylinder
Net cage, including internal layer net cage and outer layer net cage, 3-4 centimetres of the internal layer net cage mesh, outer layer net cage mesh 20-30 mesh, outside
Tile one layer of bottom fortune windmillpalm sheath-fibre for the top of layer net cage bottom, the lower section of internal layer net cage bottom, in internal layer net cage side wall and outer layer net
One layer of side wall fortune windmillpalm sheath-fibre is suspended on the lower section periphery of case side wall in midair, and the mesh sheet covering of one layer of black is covered in outer layer net cage top suitable for reading
Layer, the area of the mesh sheet coating are more than the suitable for reading of outer layer net cage.
Beneficial effect：Using the utility model spawning net cage, spawning net cage is arranged in the excellent waters of water quality, note
The catfish parent population for penetrating oxytocins is positioned in spawning net cage, and catfish parent population lays eggs in net cage of laying eggs, and fish-egg invests net cage side wall
And on the fortune windmillpalm sheath-fibre of net cage bottom, after catfish Gunther parent fish spawning, internal layer net cage is collapsed, harvesting catfish parent population, catfish ovum is in outer layer net
Hatch in case, the utility model design is simple, easy to use, and hatch fish roe rate is high.
Brief description of the drawings
Fig. 1 is the utility model structure chart.
In figure：1 mesh sheet coating, 2 internal layer net cages, 3 outer layer net cages, 4 side wall fortune windmillpalm sheath-fibres, 5 bottom fortune windmillpalm sheath-fibres, 6 outer layer nets
Case bottom.
Embodiment
It is described with reference to the drawings the utility model, a kind of catfish lays eggs net cage, it is characterized in that, spawning net cage is double-deck cylinder
Net cage, including internal layer net cage 2 and outer layer net cage 3,3-4 centimetres of 2 mesh of internal layer net cage, the mesh 20-30 mesh of outer layer net cage 3,
Tile one layer of bottom fortune windmillpalm sheath-fibre 5 in the lower section of the top of outer layer net cage bottom 6, internal layer net cage bottom, in internal layer net cage side wall and
One layer of side wall fortune windmillpalm sheath-fibre 4 is suspended on the lower section periphery of outer layer net cage side wall in midair, in the covering one layer of black in top suitable for reading of outer layer net cage 3
Mesh sheet coating 1, the area of the mesh sheet coating 1 are more than the suitable for reading of outer layer net cage 3.
Beneficial effect：Using the utility model spawning net cage, spawning net cage is arranged in the excellent waters of water quality, note
The catfish parent population for penetrating oxytocins is positioned in spawning net cage, and catfish parent population lays eggs in net cage of laying eggs, and fish-egg invests net cage side wall
And on the fortune windmillpalm sheath-fibre of net cage bottom, after catfish Gunther parent fish spawning, internal layer net cage is collapsed, harvesting catfish parent population, catfish ovum is in outer layer net
Hatch in case, the utility model design is simple, easy to use, and hatch fish roe rate is high.
