Abstract
An egg selecting device for salmonidae fishes relates to an egg selecting device and aims to resolve the problem that an existing egg clamping selecting method adopts manual operation and wastes labor and time, and a salinity separation method is poor in separation effect. A three-way pipe consists of a first branch pipe, a second branch pipe and a third branch pipe which are mutually communicated, the first branch pipe is communicated with an egg selecting pipe, the second branch pipe is communicated with a water sucking pipe, the lower end of the third branch pipe is inserted in an egg collecting bottle, a plurality of through holes are uniformly distributed on an egg stopping plate, the egg stopping plate is located in the second branch pipe, and a water sucking device is mounted on the water sucking pipe. The egg selecting device is used for selecting eggs of the salmonidae fishes.
Description
Technical field
The utility model relates to a kind of egg apparatus of choosing, and is specifically related to a kind of salmon fishes and chooses egg apparatus.
Background technology
Dead ovum in the salmon fishes incubating oosperm process can grow fungi usually in a large number, causes the ovum alive death of going mouldy, thereby reduces the salmon fishes hatchability of fertile eggs greatly, brings about great losses.And before salmon fishes fertilized egg is grown eyed eggs through certain hatching accumulated temperature; The sensitive periods that belongs to the incubating oosperm stage; Can not touch; Remove operation so will wait until for dead ovum that development of fertilized ova could be chosen dead ovum to the eyed eggs stage, this just needs in a single day grow eyed eggs and will concentrate and choose ovum and operate.
The selection method of dead ovum comprises ovum folder selecting method and salinity partition method in the existing eyed eggs, and wherein ovum folder selecting method adopts manual operation, and is time-consuming; The salinity partition method in specific operation process owing to the dead ovum and the reasons such as the ovum difference of specific gravity is less, the operator lacks experience of living cause this method to be difficult to obtain desirable separating effect.
To sum up, existing ovum folder selecting method adopts manual operation, time-consuming and salinity partition method inferior separating effect.
The utility model content
The utility model is for solving the problem that existing ovum folder selecting method adopts manual operation, time-consuming and salinity partition method inferior separating effect, and then provides a kind of salmon fishes to choose egg apparatus.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: the salmon fishes of the utility model is chosen egg apparatus and is comprised and choose oviduct, three-way pipe, collection ovum bottle, suction hose, retaining ovum plate and water aspirator; Said three-way pipe is made up of first arm, second arm and the 3rd arm; Said first arm, second arm and the 3rd arm are interconnected, said first arm with choose oviduct and be communicated with, the said second arm suction hose is communicated with; The lower end of said the 3rd arm is inserted in the collection ovum bottle; Be uniformly distributed with on the said retaining ovum plate and have a plurality of through holes, said retaining ovum plate is positioned at second arm, and said water aspirator is installed on the suction hose.
The beneficial effect of the utility model is:
The salmon fishes of the utility model is chosen egg apparatus constantly flows the water in the suction hose through water aspirator; Aim at the ovum of living as long as will choose the suction ovum end of oviduct; Under the effect of retaining ovum plate; The ovum of living will fall in the collection ovum bottle along with current automatically, has heightened greatly and has chosen ovum efficient, has improved the accuracy rate of choosing ovum simultaneously greatly;
The salmon fishes of the utility model ovum of living when choosing egg apparatus and having guaranteed operation stops in water all the time, and the ovum damage is little to living; The utility model also has the advantage that volume is little, in light weight, easy to carry and cost is low.
Description of drawings
Fig. 1 is that the master that the salmon fishes of the utility model is chosen egg apparatus looks sketch map.
Embodiment
Embodiment one: as shown in Figure 1; The salmon fishes of this embodiment is chosen egg apparatus and is comprised and choose oviduct 1, three-way pipe 2, collection ovum bottle 3, suction hose 4, retaining ovum plate 5 and water aspirator 7, and said three-way pipe 2 is made up of the first arm 2-1, the second arm 2-2 and the 3rd arm 2-3, and the said first arm 2-1, the second arm 2-2 and the 3rd arm 2-3 are interconnected; The said first arm 2-1 with choose oviduct 1 and be communicated with; The said second arm 2-2 suction hose 4 is communicated with, and the lower end of said the 3rd arm 2-3 is inserted in the collection ovum bottle 3, is uniformly distributed with on the said retaining ovum plate 5 and has a plurality of through hole 5-1; Said retaining ovum plate 5 is positioned at the second arm 2-2, and said water aspirator 7 is installed on the suction hose 4.
Said water aspirator 7 is a prior art.
