Description
Technical field
The invention belongs to technical field of aquaculture equipment, and in particular to a kind of hatching apparatus of quick separating fish eggs and larvae.
Background technology
At present, field acquisition investigation and the concern and investment of manual acquiculture and scale of the people to fish be increasingly
Greatly.Many investigators and researcher are often carrying out fish-egg and prelarva collection investigation in different waters, and
In sampling process, fish-egg and prelarva are often captured by netting gear at the same time, and efficiently separate screening fish-egg and prelarva, while ensure sample
This survival rate and vigor, and hatch fish roe become the top priority of follow-up work.But since fish eggs and larvae sample is smaller, is not easy
Distinguishing, investigator usually requires one to be suctioned out fish-egg one from fish-egg and the biased sample of prelarva with suction pipe etc., this
Sample is very time-consuming and laborious, and drawing repeatedly has sample certain destruction, and the possibility for omitting sample is larger.In addition, cultivation
Incubator takes up a large area, water requirement is more, it does not form the circulatory system, wastes great lot of water resources, cause it is water stain everywhere, easily
Cause personnel's electric shock accident and property loss.Part fish-egg has stickiness at the same time, in hatching process, when embryonated egg is excessive,
Hatching cylinder bottom portion can be deposited on, sticking together, causes embryonated egg and water, the contact area of oxygen to reduce, generation saprolegniasis, and this
Kind disease easily infects, once one piece of embryonated egg illness, glutinous embryonated egg together can be fallen ill in flakes.
The content of the invention
It is an object of the invention to provide it is a kind of can quickly, a large amount of, safe separating fish eggs and larvae hatching apparatus.
The hatching apparatus of quick separating fish eggs and larvae provided by the invention, profit is repeated by water circulation system to Spawning water
With reducing the usage amount and discharge capacity of Spawning water, the wave of water resource can be greatly decreased by filtering recycling in water
Take, and pollution on the environment.
The hatching apparatus of quick separating fish eggs and larvae provided by the invention, its structure is shown in Figure 1, including：Separate cup
1st, delivery pipe 2, sieve 3, prelarva cylinder 4, water tank 5, water treatment system 6, long water-supply-pipe 7, short water-supply-pipe 8, connection screw thread 9；Wherein：
The separate cup 1 is a upper opening of transparent vessel, for separating fish-egg prelarva, while hatches fish-egg.Container material
Can be glass or other transparent materials.
The prelarva cylinder 4 is used to carry prelarva, its bottom and surrounding have apopore, ensures water circulation；The level of prelarva cylinder 4
Position is slightly below separate cup 1, is connected between prelarva cylinder 4 and separate cup 1 by delivery pipe 2, and the prelarva in separate cup 1 passes through delivery pipe
2 move about into prelarva cylinder 4, and the gentle difference in height of delivery pipe 2 can protect prelarva, ensure larval activity；
The sieve 3 is attached to 4 surrounding of prelarva cylinder, gap comparatively dense and has certain water penetration, can pass through one with certain flow rate
Part water, while ensure that prelarva cylinder 4 has certain water, ensure larval activity.The sieve 3 can ensure that prelarva stays in prelarva cylinder 4,
It is convenient to collect transfer prelarva；Enter water tank 5 from 4 apopore outflow water of prelarva cylinder；
The water tank 5 is used to contain most of water, and the place of water process is provided for water treatment system 6；
Water tank 5 passes sequentially through long water-supply-pipe 7 and short water-supply-pipe 8 and is connected with separate cup 1；Between long water-supply-pipe 7 and short water-supply-pipe 8 by
Connection screw thread 9 connects；
The water treatment system 6 is arranged in water tank 5, for carrying out the processing such as solid absorption and filtering to recirculated water, ensures water
Matter and water circulation.
The long water-supply-pipe 7 is used to recirculated water being transported to short water-supply-pipe 8, is provided for separate cup 1 and whole invention device
Recirculated water.
The water outlet of the short water-supply-pipe 8 close to 1 bottom of separate cup, by the circulation water transport that long water-supply-pipe 7 conveys to point
From in cup 1, travelling power upwards is provided to prelarva, and fish-egg then leaves 1 bottom of a cup of separate cup.
The effect of the connection screw thread 9 is the long water-supply-pipe 7 of separation and short water-supply-pipe 8, easy to add sample to separate cup 1.
In the present invention, water-bath 10 is additionally provided with below separate cup 1, for being heated to water body in separate cup 1, and in real time
Monitoring temperature, ensures sample survival rate.
The hatching apparatus that the present invention designs can be used in series, and form scale separation and hatching；And controlled by control centre
The modules such as large-scale water treatment system, temperature sensor, PH sensor, aerator and air-conditioning, monitor water quality and control fish-egg in real time
The separation hatching of prelarva, realizes a large amount of, lot splitting fish eggs and larvae and hatching fish-egg, and water conservation simultaneously reduces security risk,
It is shown in Figure 2.
Brief description of the drawings
Fig. 1 is the hatching apparatus structural diagrams of quick separating fish eggs and larvae of the present invention.
Fig. 2 separates and hatches schematic diagram for scale.
Embodiment
During using the present invention, sample is added into separate cup 1 first, certain recirculated water is passed through to separate cup, provided to prelarva
Travelling power upwards, and fish-egg then leaves separate cup bottom, prelarva enters prelarva cylinder 4,4 bottom of prelarva cylinder and four by delivery pipe 2
There is apopore week, ensure water circulation, while post sieve 3, sieve 3 can ensure that prelarva stays in prelarva cylinder 4, and convenient collection transfer is young
Fish, this sieve are attached to prelarva cylinder surrounding, gap comparatively dense and have certain water penetration, can be with certain flow rate through a part
Water, while ensure that prelarva cylinder 4 has certain water, ensure larval activity.Enter water tank 5, by water from the 4 apopore water outlet of prelarva cylinder
Separate cup 1 is entered by long water-supply-pipe 7, short water-supply-pipe 8 after the filtering clean water of the circulatory system 6, and a determined power is provided.Connect spiral shell
The setting of line 9 is easy for separating long water-supply-pipe 7 and short water-supply-pipe 8, convenient to add sample to separate cup 1.The setting of water-bath 10
It is to water body heating and real-time monitoring temperature in separate cup 1, ensures sample survival rate.The present invention can efficiently separate fry son
Fish, and this device can be used in series, realize a large amount of lot splitting fish eggs and larvaes, while thorough fish eggs and larvae can be distinguished, it is right
Sample injury degree is small.
