Abstract
The utility model discloses a giant salamander fertilization disc which comprises a fertilization disc body and a water inlet positioned at the upper end of the fertilization disc body. A helical rib is formed at the bottom of the fertilization disc body, and a drain hole is formed at the top of the rib. The fertilization disc can improve the fertilization rate and the hatching rate of giant salamanders in a greater degree.
Description
Technical field
The utility model relates to the fertilization device of a kind of giant salamander, particularly giant salamander fertilization dish.
Background technology
The giant salamander is China second class protection aqua-marine life, for the quantity that increases giant salamander population with satisfy the demand in market, need propagate artificially to the giant salamander.The existing mode that the giant salamander is carried out artificial insemination is generally " doing wet method " fertilization.The artificial propagation of the giant salamander has some specific (special) requirements, adopts common circular magnetic disc or dissect square plate to be difficult to meet the demands.At first, giant salamander chalaza is the long band of bead chain shape, but not disperse shape; Caused giant salamander chalaza to be tied a knot easily, the chalaza of knotting not only can influence the quality of fertilization, and causes animal-vegetal in egg membrane, to be inverted in early days easily in embryonic development; And cause embryo's deformity, finally cause death; Secondly, the sperm viability of the giant salamander a little less than, the life-span is shorter, activation of spermatozoa needs a large amount of dissolved oxygens; At last, water body is had relatively high expectations around the giant salamander fertilized egg, and fertilized egg needs fine bourn to stimulate, and takes away metabolic waste through current simultaneously.If adopt existing circular magnetic disc or dissection square plate to carry out giant salamander artificial insemination, fertilization rate of the giant salamander and incubation rate are all lower.
Summary of the invention
The purpose of the utility model provides a kind of giant salamander fertilization dish, to improve fertilization rate and the incubation rate of the giant salamander.
The said giant salamander fertilization of the utility model dish comprises fertilization dish body and the water inlet that is positioned at fertilization dish body upper end, is provided with spiral convex tendon in the bottom of fertilization dish body, and the convex tendon top offers osculum.
Bottom centre is provided with cylinder at fertilization dish body, and cylindrical height is higher than the height of muscle shape body, offers the water level spacing hole at the top of cylinder.
The spiral convex tendon that fertilization dish body bottom is provided with makes and forms spiral helicine groove in the fertilization dish.During use, the chalaza of the giant salamander is moved towards to be positioned in the spiral helicine groove along spiral, water flows in the fertilization dish from water inlet, and flows out the fertilization dish from the osculum at convex tendon top; When the water in the fertilization dish was too many, then the water level spacing hole from the cylinder top of fertilization dish body bottom centre flowed out.
The said giant salamander fertilization of the utility model dish, owing to be provided with spiral convex tendon in fertilization dish body bottom, the chalaza of the giant salamander will be retrained by convex tendon, regularly be arranged in the fertilization dish, thereby avoid the knotting in giant salamander chalaza well; Water flows into the fertilization dish from the water inlet of fertilization dish upper end; Play certain dissolved oxygen effect; The water that flows in the fertilization dish flows out the fertilization dish through the osculum on the muscle shape body, thereby has formed fine bourn, has both stimulated fertilized egg; Taken away the refuse that fertilized egg produces again, so this fertilization dish can improve fertilization rate and the incubation rate of the giant salamander largely.
Description of drawings
Front view when Fig. 1 is placed with the chalaza for the utility model;
Fig. 2 is along the cutaway view of A-A line among Fig. 1.
Embodiment
In order further to explain the technical scheme of the utility model, come in conjunction with the drawings below the utility model is set forth in detail.
As illustrated in figs. 1 and 2, this giant salamander fertilization dish comprises fertilization dish body 1 and the water inlet 2 that is positioned at fertilization dish body upper end, is provided with spiral convex tendon 3 in the bottom of fertilization dish body, and the top of convex tendon 3 offers osculum 4.Bottom centre is provided with cylinder 5 at fertilization dish body, and the height of cylinder 5 is higher than the height of convex tendon 3, offers water level spacing hole 6 at the top of cylinder 5.
Claims (2)
1. giant salamander fertilization dish comprises fertilization dish body (1) and is positioned at the water inlet (2) of fertilization dish body upper end that it is characterized in that: be provided with spiral convex tendon (3) in the bottom of fertilization dish body, the top of convex tendon offers osculum (4).
2. according to the said giant salamander fertilization of claim 1 dish, it is characterized in that: bottom centre is provided with cylinder (5) at fertilization dish body (1), and cylindrical height is higher than the height of muscle shape body, offers water level spacing hole (6) at the top of cylinder.
