Abstract
The utility model relates to a zygote collecting and cleaning device for sea water shellfishes. The zygote collecting and cleaning device comprises a spawning groove, a cleaning water groove and a collecting net, wherein the upper half part of the spawning groove is square, and the bottom of the spawning groove is in the form of a rectangular pyramid; a porous plate is arranged at the bottom of the spawning groove; shellfishes are placed on the porous plate; the bottom end of the spawning groove is connected with a zygote conveying pipe; the other end of the zygote conveying pipe is obliquely aligned with the collecting net; the cleaning water groove is formed above the collecting net, and is filled with sea water; the lower end of the cleaning water groove is connected with a sea water supply pipe; the other end of the sea water supply pipe is positioned above the collecting net with which the zygote conveying pipe is obliquely aligned; a zygote conveying valve is arranged on the zygote conveying pipe; and a sea water supply valve is arranged on the sea water supply pipe. The zygote collecting and cleaning device has the advantages of simple technical structure, easiness and convenience in operating, full utilization of the characteristic of the settleability of zygotes, high collecting efficiency, and increase in the working efficiency since the zygotes can be flushed during collection.
Description
Technical field
The utility model belongs to marine shellfish seedling growing process field, particularly relates to a kind of marine shellfish fertilized egg and collects and cleaning device.
Background technology
Carrying out marine shellfish when growing seedlings, observing its fertilization and growth course or carrying out multiploid induction, is convenient the observation and operation, often needs to collect the fertilized egg of shellfish.At present, collection method commonly used mainly is to utilize flexible pipe to be siphoned into from spawning pond in the bolting silk net, and again with the filtering sea flushing, but this method generally needs two people to operate together, and is not too convenient.And because the shellfish ovum mostly is demersal egg greatly, even if inflation, the ovum of collecting during siphon is also less, and efficient is not high.
In addition, in order to improve the fertilized egg hatching rate, also need to control the condition of fertilization.The shellfish that has such as chlamys farreri, Patinopecten yessoensis etc. can be differentiated male and female by observing gonadal color, separately fertilization, thus control rational smart ovum ratio.And for some hermaphroditism or the tighter shellfish of closed shell, can't differentiate male and female, when induced spawning, run into the too much problem of sperm in the water body through regular meeting.If sperm is too much around the ovum, can produce polyspermy, cause development of fertilized ova bad or lopsided.Simultaneously, too much seminal fluid also can be ruined water quality, influences the growth of fertilized egg.Therefore, need in time fertilized egg to be cleaned
Cleaning method commonly used at present comprises: by a large amount of inflations seminal fluid is formed foam, pull out with net, this method needs by special messenger's repeatable operation; Or add filtering sea by a minute pond and reduce sperm concentration, but do not change the ratio of ovum and sperm yet, and operate comparatively loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of marine shellfish fertilized egg and collects and cleaning device, improves the fertilized egg hatching rate.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of marine shellfish fertilized egg to collect and cleaning device, comprise the groove of laying eggs, cleaning sink and collecting net, the described groove the first half of laying eggs is square, the bottom is the rectangular pyramid body, the described bottom land of laying eggs is equipped with porous plate, place shellfish on the described porous plate, the described bottom land end of laying eggs connects the fertilized egg carrier pipe, the oblique aligning collecting net of the described fertilized egg carrier pipe other end, cleaning sink is equipped with in described collecting net top, hold seawater in the described cleaning sink, described cleaning sink lower end connects the seawater supply pipe, the described seawater supply pipe other end is positioned at the top of the oblique aligning collecting net of fertilized egg carrier pipe, on the described fertilized egg carrier pipe fertilized egg transfer valve is housed, the seawater supply valve is housed on the seawater supply pipe.
Described fertilized egg transfer valve is ball valve, and the seawater supply valve is gate valve.
Described collecting net surrounds a hemispherical, and described collecting net mesh-density is about 400 order/inches, and the net holder is stainless steel material.
Described collecting net is erected on the rack.
Described rack is welded by reinforcing bar, and network interface is circular, and diameter is slightly less than the collecting net bore, and the bottom is by three reinforced bar support.
The cuboid box that described cleaning sink is made for the PVC plastic plate.
Beneficial effect
The utility model technical pattern is simple, and is easy and simple to handle, single can finishing; The characteristics of the heavy property of fertilized egg have been taken full advantage of, the collection efficiency height; But fertilized egg is washed while collecting, and has improved operating efficiency.
