Abstract
The utility model relates to an attachment for spawning of parent fish, in particular to a fish nest for incubation of adhesive roe. The fish nest comprises a square frame and a silk fishing net fixed in the square frame. According to the utility model, the fish nest comprises the square frame and the silk fishing net fixed in the square frame, through laying the fish net provided by the technical scheme at the bottom of a spawning pool, the silk fishing net is 20-40 meshes, and the mesh size is within 0.85-0.425 mm, so that the roe can be attached on the silk fishing net, the adhesive rate of the roe is effectively improved, and meanwhile, the fish nest is convenient for roe recovery and incubation management.
Description
Affiliated technical field
The utility model relates to the lay eggs attachment of usefulness of a kind of carp parent population, particularly used fish nest during the viscosity hatch fish roe.
Background technology
The fish nest is the lay eggs attachment of time spent of parent population, adopts very thin racemosus in water, to be prone to scatter usually and not perishable material forms, like the coring of willow in pasture and water, the water, fortune windmillpalm sheath-fibre etc.After fish nest material is sterile-processed, be bundled into bundle, be placed in the spawning pond, the attachment of fish-egg is provided during for male and female fish spawning and fertilization with suspention or the form of placing side by side.There is making in above-mentioned fish nest in practical application, it is loaded down with trivial details to use; The fish-egg adhesive rate is low; Become the key technique that the commercialization of restriction carp is grown seedlings.
Summary of the invention
The purpose of the utility model is to overcome the defective that prior art exists, provide a kind of simple in structure, be prone to preserve, service life is long, can effectively improve the carp roe Hatching fish net of spawning efficiency and adhesive rate.
The technical scheme of the utility model is: a kind of carp Hatching fish net of laying eggs is characterized in that the fish nest is made up of square frame and the silk screen that is fixed in the square frame.
The order number of above-mentioned silk screen is 20-40 orders.
Be fixed with rope on the above-mentioned square frame.
The fish nest of the utility model is made up of square frame and the silk screen that is fixed in the square frame; Through be paved with the fish nest of present technique scheme in the spawning pond bottom; Make fish-egg be scattered, adhere on the silk screen when fish lays eggs, can effectively improve the adhesive rate of fish-egg, be convenient to reclaim fish-egg and hatching management simultaneously.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the fish nest is made up of square frame 3 and the silk screen 2 that is fixed in the square frame,
Because the diameter of fish-egg is generally about 1.4-0.8 ㎜, so adopt 20-40 purpose silk screens.For the ease of regaining the fish nest, on square frame, be fixed with rope 1.
When carp lays eggs, be paved with this fish nest in the spawning pond bottom, so just can make the interior carp roe of spawning pond all attached on the silk screen, during hatching the fish nest is taken out through the rope fixed placement in the hatchery.Square frame can adopt metal material such as iron, aluminium etc. to process.Silk screen can adopt metal or nonmetal silk screen.
Claims (3)
