Abstract
A pelteobagrus fulvidraco artificial propagation hatching barrel relates to the technical field of fry propagation, particularly to the technical field of artificial propagation of pelteobagrus fulvidraco, and includes an upper cylindrical barrel body and a lower cone-shaped barrel body with the taper of 34-38 degrees, wherein the upper end of the lower barrel body is connected to the lower end of the upper barrel body; an overflow opening is formed in the side wall of the upper barrel body; the lower end of the lower barrel body is connected to a fry outlet pipe; a switching valve is arranged on the fry outlet pipe; the upper barrel body, the lower barrel body and the fry outlet pipe are provided with smooth inner surfaces respectively; and the upper barrel body is connected with the lower barrel body through a smooth transitional surface. The pelteobagrus fulvidraco artificial propagation hatching barrel facilitates hatch, meets requirements for mass production of fries of pelteobagrus fulvidraco and improves the parental induced spawning rate of pelteobagrus fulvidraco.
Description
Technical field
The utility model relates to the artificial propagation techniques field of fish breeding technical field, particularly yellow cartfish.
Background technology
The hatching pail structure as the figure that used: be divided into three parts: ladle body, bucket cover and annex in the past.Ladle body is with mostly adopting black sheet iron to make, slightly like conical.Ladle body height is 1m, and the back cut diameter of bucket is 62cm, and end opening maximum is directly 46cm, and bottom centre has a water inlet pipe, and bore is to join with rubber tube under 2.5 centimetres.Outlet pipe is arranged on the 4cm place suitable for reading apart from ladle body, and bore and length are identical with water inlet pipe.For emerge convenient for the purpose of, also can connect at water inlet pipe place the pipe of emerging.It is that 46cm, lower port diameter are the cover frame of 56cm, high 25cm that bucket cover is made back cut diameter with the wide thin bamboo strips used for weaving sheet of 2cn, in it, with per inch 60 object nylon grenadines, makes water outlet screen covering, and end opening is sewed on foamed plastics or coarse cloth, to reach the object that is adjacent to ladle body top.Annex comprises wood, the brandreth of supporting ladle body, the tap of rubber tube and control water inlet flow velocity or clip etc.
The shortcoming of hatching pail in the past:
1, the appearance ovum amount of each hatching pail is 20～400,000, and novel hatching pail appearance ovum amount is 1,000,000;
2, dead ovum, egg membrane etc. can be attached on guard, not easy to clean;
3, complicated operation.
Utility model content
The utility model object is the yellow cartfish artificial propagation hatching pail that proposes a kind of handled easily, improves fish breeding rate.
The utility model comprises that cylindrical upper barrel body and tapering are the conical lower barrel body of 36 ± 2 °, the upper end of described lower barrel body is connected to the lower end of described upper barrel body, sidewall at upper barrel body arranges gap, connects the pipe of emerging in the lower end of lower barrel body, is going out switch valve is set on pipe; Described upper barrel body, lower barrel body and the pipe of emerging are respectively equipped with smooth inner surface, and described upper barrel body is connected with smooth transition face with lower barrel body.
The utility model also taps into water pipe on the side on pipe of emerging, and water intaking valve is set on water inlet pipe.
The internal diameter of described upper barrel body is 0.65～0.70m, highly for 0.2m, the height of lower barrel body is 1.0m.
Further, the tapering of described conical lower barrel body of the present utility model is 36 °.
This hatching pail has following characteristics:
(1) the cone angle of hatching pail is little, and fertilized egg can not piled up at inner wall of barrel, and evenly, emergence rate is high in rolling;
(2) design head is larger, utilize the heavy feature of yellow cartfish fertilized egg, impulsive force is controlled at fertilized egg and stirs the position of 1/3 1/2 at staving height, fertilized egg is heavier can not flowed out from gap, and unfertilized ovum proportion is lighter, can overflow with current, can to hatching, not impact because of unfertilized ovum is mouldy;
(3) hatching pail capacity is large, can hold yellow cartfish fertilized egg 3～4kg, 80～1,000,000 tails of emerging;
(4) hatching pail is not established screen pack, and yellow cartfish yolk seedling can not overflow with current than a little less than great, Burden-Swimming Ability of KM, and the egg membrane dissolving can flow out from gap with water, and the operation of brush net while having saved fry rupture of membranes greatly reduces the labour intensity of hatching operation;
(5) collection seedling is convenient, and collection Miao Shi is emerged a flexible pipe of pipe connection to storage pond, holding pond, turns off water intaking valve static 30 seconds, opens the valve of emerging, and yolk seedling can utilize hydraulic pressure automatically by flexible pipe, to enter storage pond, holding pond.
In a word, the utility model can conveniently be hatched operation, adapts to the needs of yellow cartfish seedling large-scale production, can improve yellow cartfish parent's spawning rate.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
The utility model can adopt brick mix structure, by Mold Making, requires inner surface smooth; Also can adopt galvanized iron sheet or fiberglass to make.
Hatching pail total height 1.20m, water body volume are about 0.20～0.25m
3, by cylindrical upper barrel body 1 and conical lower barrel body 2, formed.
The internal diameter of lower barrel body 1 is 0.65～0.70m, highly for 0.2m, at the sidewall of upper barrel body 1, gap 3 is set.
The height of lower barrel body 2 is 1.0m, and tapering α is 36 ± 2 °, and preferably 36 °, the upper end of lower barrel body 2 is connected to the lower end of upper barrel body 1 with smooth transition face.
In the lower end of lower barrel body 2, connect the pipe 4 of emerging that adopts Φ 32mm or Φ 40mmPVC sclerine to make, at the other water pipe 5 that taps on pipe 4 of emerging, on pipe 4, switch valve 6 is set emerging, water intaking valve 7 is set on water inlet pipe 5.
