Description
Technical field
The invention belongs to aquatic fry growing device field, relate to particularly and a kind ofly open fat device for newly hatched larvae.
Background technology
Most seawater swimming fish have fish glue organ, and fish glue organ can regulate body density, assisted respiartion and accept the effects such as sound.There is no gas in fish glue when pipe fish glue class and most of physoclistous fish hatch from ovum, but in artificial culture fry process, by the bubble of eating in water body, gas is filled with in fish glue device by pneumatic duct.Seawater fish artificial breeding is opened in fish glue process, prelarva easily occur the inflation of fish glue bad, open pneumatic duct size uneven, do not open the phenomenons such as fish glue, what affect postlarva opens fish glue rate, causes a large amount of lopsided and dead.Therefore, the growth of fish glue organ has vital impact to larva and juvenile health, is one of key factor of seawater fish artificial breeding success or failure.
Under artificial breeding condition, what the mode usually utilizing gas charging stone to inflate carried out fish opens fish glue, mainly there is following shortcoming in this mode: (1) aeration quantity is difficult to control, aeration quantity is excessive or the too small size all easily reducing inflation rate (2) gas-filled bubbles of fish glue is uneven, under causing fish glue dysplasia (3) intensive culture condition, the water surface has the oil film that one deck bait produces, and the bubble that gas charging stone produces easily is combined with oil film, fish eats in conjunction with the bubble of oil film, affects the inflation rate of fish glue.At present, prior art there is no make newly hatched larvae eat the homogeneous bubble of clean size, improve survival rate, simple to operate open fish glue device.
Summary of the invention
The technical problem that the present invention solves is to provide a kind ofly opens fish glue device for newly hatched larvae, the combination of this apparatus structure is simple, cost of manufacture is low, prelarva can be made to eat clean, minute bubbles of uniform size, improve inflation rate and the seedling percent of prelarva, and effectively can also remove water-surface oil film, guarantee that water quality is pure and fresh.
The present invention is achieved through the following technical solutions:
Open a fish glue device for newly hatched larvae, open the right-angled trapezium that fish glue device has a camber hypotenuse, the bottom of right-angled trapezium is a Multi-hole air filling pipe, and Multi-hole air filling pipe is inflated in device.
Further, the described camber hypotenuse opening fish glue device is connected to form by 135 ° of elbows.
Open a fish glue device for newly hatched larvae, it comprises: main direct-connected adapter, resistance film tube connector, block film tube connector, hold together film tube connector, Multi-hole air filling pipe, 90 ° of elbows, 135 ° of elbows and tube connector plugs;
The direct-connected adapter one end of described master utilizes tube connector plug to block, and the other end is connected with resistance film tube connector by 90 ° of elbows;
Described film tube connector one end of blocking is connected with resistance film tube connector by 90 ° of elbows, the other end by 135 ° of elbows with hold together film tube connector and be connected, 135 ° of exterior angles being out fish glue device, hold together the film tube connector other end and utilize tube connector plug to block;
Described Multi-hole air filling pipe is fixed on main direct-connected adapter and holds together above film tube connector, the pore of Multi-hole air filling pipe is towards the water surface in device, preferred embodiment is the pore of Multi-hole air filling pipe towards skew back in device lower 45 °, Multi-hole air filling pipe is near one end tube connector plug blocking of main direct-connected adapter, and the other end is gas tube junction.
The present invention's beneficial effect compared with prior art:
1) the present invention evenly can be blown by the 45 ° of waters surface in oblique below in ladder structure of right angle of the pore on Multi-hole air filling pipe, the oil film blowing pond water surface flows to the top of right-angled trapezium, assembles, right-angled trapezium is made to keep clean near territory, the Multi-hole air filling area under control water surface, thus make in water, to form clean micro-bubble, open fish glue phase prelarva to eat clean minute bubbles, thus reach and improve the object that prelarva opens fish glue rate.
2) the present invention by the water surface to the method for gas, to tolerance evenly, stable, easily regulate, and can alleviate to concentrate and cause in culturing pool the prelarva seedling that swims to assemble to gas.
3) the floating oil film of newly hatched larvae cultivation pond water surface flows in trapezium structure apex zone, enrichment to use the present invention to blow, and effectively collecting the oil film cultivating pond water surface, providing prerequisite for forming clean bubble of uniform size in water body.
4) textural association of the present invention is simple, cost of manufacture is low, is suitable for large-scale industrialized cultivation and produces.
