Description
Technical field
A kind of the utility model category technical field of aquaculture equipment, and in particular to hatching dress of quick separating fish eggs and larvae
It sets.
Background technology
Currently, people to the field acquisition investigation of fish and the concern and investment of manual acquiculture and scale increasingly
Greatly.Many investigators and researcher are often carrying out acquisition investigation in different waters to fish-egg and prelarva, and
In sampling process, fish-egg and prelarva are often captured by netting gear simultaneously, and efficiently separate screening fish-egg and prelarva, while ensureing 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
It distinguishing, investigator usually requires that fish-egg is sucked out one by one from fish-egg and the mixing sample of prelarva with suction pipe etc., this
Sample is very time-consuming and laborious, and draw repeatedly has certain destruction to sample, and the possibility for omitting sample is larger.In addition, cultivation
Incubator takes up a large area, water requirement is more, 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 simultaneously, in hatching process, when fertilized eggs are excessive,
It can be deposited on hatching cylinder bottom portion, stick causes fertilized eggs and the contact area of water, oxygen to reduce together, generation saprolegniasis, and this
Kind disease easily infects, once one piece of fertilized eggs illness, glutinous fertilized eggs together can fall ill in flakes.
Invention content
The purpose of this utility model is 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 utility model, by water circulation system to Spawning water weight
It is multiple to utilize, the usage amount and discharge capacity of Spawning water are reduced, water resource can be greatly decreased by filtering recycling in water
Waste and pollution on the environment.
The hatching apparatus of quick separating fish eggs and larvae provided by the utility model, structure is shown in Figure 1, including：Point
From cup 1, 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, is used for separating fish-egg prelarva, while hatching fish-egg.Container
Material can be glass or other transparent materials.
The prelarva cylinder 4 has apopore for carrying prelarva, bottom and surrounding, ensures water cycle；The level of prelarva cylinder 4
Position is slightly below separate cup 1, is connected to by delivery pipe 2 between prelarva cylinder 4 and separate cup 1, and the prelarva in separate cup 1 passes through delivery pipe
In 2 travellings to prelarva cylinder 4, 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 be saturating with certain flow rate
A part of water is crossed, while ensureing that prelarva cylinder 4 has certain water, ensures larval activity.The sieve 3 can guarantee that prelarva stays in prelarva
Cylinder 4 facilitates collection transfer prelarva；Enter water tank 5 from 4 apopore outflow water of prelarva cylinder；
The water tank 5 is the place that water treatment system 6 provides water process for containing most of water；
Water tank 5 passes sequentially through long water-supply-pipe 7 and short water-supply-pipe 8 is connected to separate cup 1；Long water-supply-pipe 7 and short water-supply-pipe 8 it
Between connected by connection screw thread 9；
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, protects
Demonstrate,prove water quality and water cycle.
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 entire invention device
Recirculated water.
The water outlet of the short water-supply-pipe 8 close to 1 bottom of separate cup, the cycle water transport that long water-supply-pipe 7 is conveyed 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, convenient for sample is added 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 of the utility model design can be used in series, and form scale separation and hatching；And by control centre
The modules such as the large-scale water treatment system of control, temperature sensor, PH sensor, aerator and air-conditioning, monitor water quality and control in real time
The separation of fish eggs and larvae is hatched, and realizes that a large amount of, lot splitting fish eggs and larvae and hatching fish-egg, water conservation simultaneously reduce safe hidden
Suffer from, it is shown in Figure 2.
Description of the drawings
Fig. 1 is the hatching apparatus structural diagrams of the utility model quick separating fish eggs and larvae.
Fig. 2 is that scale detaches and hatch schematic diagram.
Specific implementation mode
When using the utility model, separate cup 1 is added in sample first, certain recirculated water is passed through to separate cup, gives prelarva
Travelling power upwards is provided, and fish-egg then leaves separate cup bottom, prelarva enters prelarva cylinder 4,4 bottom of prelarva cylinder by delivery pipe 2
There is apopore with surrounding, ensure water cycle, while posting sieve 3, sieve 3 can guarantee that prelarva stays in prelarva cylinder 4, and collection is facilitated to turn
Prelarva is moved, this sieve is attached to prelarva cylinder surrounding, gap comparatively dense and has certain water penetration, can penetrate one with certain flow rate
Part water, while ensureing that prelarva cylinder 4 has certain water, ensure larval activity.From the water outlet of 4 apopore of prelarva cylinder into water tank 5, pass through
It crosses after the filtering clean water of water circulation system 6 and separate cup 1 is entered by long water-supply-pipe 7, short water-supply-pipe 8, and a determined power is provided.Even
The setting for connecing screw thread 9 is easy for detaching long water-supply-pipe 7 and short water-supply-pipe 8, facilitates to separate cup 1 and sample is added.Water-bath 10
Setting is to ensure sample survival rate to water body heating and real-time monitoring temperature in separate cup 1.The utility model can effectively divide
From fry prelarva, and it can be used in series this device, realize a large amount of lot splitting fish eggs and larvaes, while thorough fish-egg can be distinguished
Prelarva is small to sample injury degree.
