Description
Technical field
The invention belongs to aquatic fry growing device field, relate to particularly and a kind ofly for newly hatched larvae, open fat device.
Background technology
Seawater swimming fish have fish glue organ mostly, and fish glue organ can regulate body density, assisted respiartion and accept the effects such as sound.When pipe fish glue class and most of physoclistous fish hatch from ovum, in fish glue, there is no gas, 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, affect the fish glue rate of opening of postlarva, cause a large amount of deformities and death.Therefore, the growth of fish glue organ has vital impact to young postlarva health, is one of key factor of seawater fish artificial breeding success or failure.
Under artificial breeding condition, conventionally the mode of utilizing gas charging stone to inflate is carried out the fish glue of opening of fish, mainly there is following shortcoming in this mode: (1) aeration quantity is difficult to control, aeration quantity size excessive or too small inflation rate (2) gas-filled bubbles that all easily reduces fish glue is inhomogeneous, cause under 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 is easily 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 clean big or small homogeneous bubble, improve survival rate, the simple to operate fish glue device of opening.
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, this apparatus structure combination is simple, cost of manufacture is low, can make prelarva clean, the minute bubbles of uniform size of eating, improve inflation rate and the seedling percent of prelarva, and can also effectively remove water-surface oil film, guarantee that water quality is pure and fresh.
The present invention is achieved through the following technical solutions:
Newly hatched larvae open a fish glue device, 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, Multi-hole air filling pipe is to inflation in device.
Further, the described camber hypotenuse of opening fish glue device is to be connected to form by 135 ° of elbows.
Newly hatched larvae open a fish glue device, 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 plug;
The direct-connected adapter of described master one end utilizes tube connector plug to stop up, and the other end is connected with resistance film tube connector by 90 ° of elbows;
The 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 that are out fish glue device, hold together the film tube connector other end and utilize the obstruction of tube connector plug;
Described Multi-hole air filling pipe is fixed on main direct-connected adapter and holds together film tube connector top, the pore of Multi-hole air filling pipe is the water surface in device, optimal way is that the pore of Multi-hole air filling pipe is towards lower 45 ° of skew back in device, Multi-hole air filling pipe stops up with tube connector plug near one end 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 can by the pore on Multi-hole air filling pipe in ladder structure of right angle tiltedly the 45 ° of waters surface in below evenly blow, the oil film that blows pond water surface flows, assembles to the top of right-angled trapezium, make right-angled trapezium keep clean near territory, the Multi-hole air filling area under control water surface, thereby make to form in water clean micro-bubble, open the fish glue phase prelarva clean minute bubbles of eating, thereby reach, improve the object that prelarva opens fish glue rate.
2) the present invention by the water surface method to gas, give tolerance evenly, stable, easily regulate, and can alleviate to concentrate to gas and cause the prelarva seedling that swims in culturing pool to assemble.
3) use the present invention will blow newly hatched larvae cultivate the floating oil film of pond water surface to flowing in trapezium structure apex zone, enrichment, effectively collect the oil film of cultivating pond water surface, for forming clean bubble of uniform size in water body, provide prerequisite.
4) textural association of the present invention is simple, cost of manufacture is low, is suitable for large-scale industrialized cultivation and produces.
