The invention recycles the replaced water, drives the rotating fan to rotate through the water, drives the air pipe to rotate and supply air to the air pipe when the rotating fan rotates, and leads the air to overflow from the air outlet hole on the air pipe, thereby avoiding the fry from flowing away along with the water and flushing oxygen into the water when the water is replaced.
Description
Technical Field
The invention relates to the technical field of aquatic product cultivation, in particular to a fry cultivation method.
Background
The newly hatched fry has a body length of 0.2-0.3 cm, also called 'fish blossom', depends on the nutrition life in the yolk sac in the absorber, and can not be put into a pond, namely, the fry can not be directly put into the pond for feeding, the fry needs to be cultivated, the newly hatched fry is fed for 20-25 days, and the fry is put into the pond after growing to about 3 cm.
In the fry breeding process, the left food materials eaten by the fries every day and the excrement generated by the fries are stored in water, the food materials and the excrement are easy to breed a plurality of bacteria in the water body, the oxygen content in the water body is reduced, the water quality is deteriorated, and therefore the water for breeding the fries needs to be replaced regularly. When the water is changed, a part of the water is usually changed and a part of the water is reserved, and when the part of the water is changed, the water flow port is usually simply blocked to prevent the fry from flowing away along with the water.
The method has the problems that the fry is easy to flow away along with water to cause fry loss when water is changed, and food and fry excrement at the bottom of the water are easy to accumulate at the bottom of the barrel in the water changing process, so that the fry is not cleaned completely and the water quality is influenced.
Disclosure of Invention
The invention aims to provide a fry rearing method for preventing fry from flowing away with water when water is replaced.
The fry rearing method in the scheme comprises the following steps:
s1, sterilizing the breeding barrel, placing clear water and hatched young fishes in the breeding barrel after the sterilizing agent in the breeding barrel is spread out, and feeding foodstuff;
s2, when water is changed every 3 days after the fry is put in, the water in the breeding barrel flows into the water return barrel from the water through holes at the bottom of the barrel for preliminary sedimentation, 30 percent of water is reserved in the breeding barrel, and the water is injected into the water treatment barrel by the water pump in the water return barrel for treatment;
s3, filtering and precipitating, chemically adsorbing and biologically treating the water in a water treatment barrel to obtain clear water, and injecting the clear water into a clear water barrel for storage;
s4, spraying clear water in a clear water bucket onto fan blades of a rotating fan from a water spraying pipe, driving the rotating fan to rotate by the clear water, driving an air pipe in clearance fit on a support frame to rotate by the rotating fan, sucking air outside the air pipe into the air pipe by a helical blade in a horn-shaped air inlet on the top end of the air pipe, enabling the air to enter the air pipe from an air inlet, and injecting the air into water in a culture bucket from an air outlet hole at the lower end of the air pipe for oxygenation;
and S5, repeating S2, S3 and S4, culturing the juvenile fish for 20-25 days until the juvenile fish grow to fry of 3-4 cm, taking out the fry and putting the fry into a pond for culture.
The beneficial effect of this scheme is that, the air can be strikeed the trachea and near the fry in water hole and open when spilling over from the venthole, prevents that the fry from flowing away from the water hole along with water, can also increase the oxygen content of aquatic with the air rush income aquatic simultaneously.
The trumpet-shaped air inlet enlarges the area of the air inlet, can increase the air inlet amount of the spiral fan blades rotating along with the air pipe, enables the impact force overflowing the air outlet hole to be larger, enables the fry not to be easily close to the air outlet hole and the water passing hole, reduces the fry flowing away from the water passing hole along with the water, and simultaneously, the increased air inlet amount can also increase the oxygen content in the water.
When the clear water is sprayed to the fan blades to drive the rotating fan to rotate, part of clear water can flow into the breeding barrel, so that the water quantity of the breeding barrel is increased, the oxygen content of the water is increased while the water quantity is increased, and the survival rate of the fry is improved.
Carry out recovery processing utilization to the water that falls of changing in this scheme to rotate the fan through the water drive and rotate, need not to increase power alone and make and rotate the fan rotation, it is more energy-conserving, during partial water inflow breeds the bucket, increases the oxygen content of water simultaneously.
Further, in the above-mentioned content S4, the water in the water jet pipe is pressurized by the booster pump and then ejected.
The clear water that rotates the fan to the spray pipe blowout pressurizes, makes rivers bigger to the impact force of rotating the fan, can let the rotation fan drive support frame pivoted speed faster, and the rotation of aspiration fan accelerates simultaneously increases the air that gets into the aquatic, increases the oxygen content of water.
Furthermore, a hairbrush is arranged at the lower end of the air pipe close to the water passing hole, when the air pipe rotates, the air pipe drives the hairbrush to rotate, and the periphery of the water passing hole is cleaned through the hairbrush.
The brush can rotate along with it when the trachea rotates, makes the brush can brush foodstuff and fish feces that the water hole department deposits, avoids piling up, can also prevent that the fry from flowing away along with water from the water hole when keeping water to flow through, makes the water of changing that the fry was cultivated more convenient.
Further, in the content S4, the support frame is placed in the water, and the air pipe is located in the water at the clearance fit position of the support frame.
When the trachea rotates, trachea and support frame clearance fit department are located the aquatic, and the trachea receives the buoyancy of water, and frictional force when having reduced the trachea and rotating makes tracheal rotation more smooth and easy.
Further, in the content S4, a check valve is provided above the air outlet near the air outlet to prevent water from entering the air pipe.
When the air pipe is submerged in water, the one-way valve is arranged, so that the phenomenon that the air cannot be filled into the water due to the fact that too much water enters the air pipe when the air pipe is not filled with air is avoided.
Further, in the content S2, the bottom surface of the cultivation barrel is inclined toward the water passing hole, so that food and fry feces on the bottom of the water are gathered at the water passing hole.
When changing water to breeding the bucket, the diapire slope of breeding the bucket can let the filth of aquatic follow the water hole and flow away, reduces the filth deposit on breeding the diapire of bucket along with water.
