1. The fry should use a dense mesh to pull the empty pond a few times before entering the pool. On the one hand, the remaining clear ponds accumulated in the bottom of the pool of drugs to fully dissolve, to prevent poisoning fish fry, on the other hand to further eliminate the enemy, if you find that the enemy can use 0.5 g / cubic meter concentration of trichlorfon Quanchiposa to kill, This concentration has no killing effect on rotifers.
2. Be sure to check whether the drug toxicity of Clear Pond has disappeared and whether the water's fatness is appropriate before the fish are in the pool. First take half a bucket of water, because sometimes the surface water toxicity has disappeared, but the bottom of the virulence is still very strong, the fry into the water observed 8 hours to 10 hours to see if normal to determine whether the fry can enter the pool. The pH should be in the range of 7 to 8.5. Secondly, according to the water color, transparency and bait biological conditions to determine the water's fatness, such as the discovery of water, fertilizer, water can be added to the adjustment, the pool of water is not enough fat, should immediately apply a small amount of fertilizer or increase artificial feed.
3. When the fry enters the pool, the temperature of the pool must not be lower than the fish temperature of 3°C. If the water temperature difference is too large, the temperature difference should be gradually adjusted and the fry can be used after entering the pool. For fish fry transported in plastic bags, the opening of the plastic bag should be slowly put into the cage pre-placed in the fishing pond before entering the pool. When the water temperature in the pool is the same as that in the bag, the pool water is gradually mixed with the water in the bag. After 10 minutes to 20 minutes of stopping, fry and water were slowly poured into the box to adjust the water temperature difference and the adaptability of the fry to the change of air pressure inside the bag. Some people called it “slow seedlingsâ€. If the fry was found to be in a supine position when the bag was opened, this is a phenomenon of carbon dioxide poisoning, as long as after the slow seedlings, put in clear water for a while to recover. If the fry is poured directly into the pool from the bag, even if the naked eye observes normal life at the time of stocking, death will occur after the pond, that is, it will die after transportation. Therefore, plastic bags to transport fry, into the pool to be particularly careful operation, slow seedling treatment is an essential and important step.
4. Disinfect the fish before entering the pool. It can be soaked with 1% baking soda for 20 minutes to 30 minutes or 10,000 IU/L penicillin solution for 1 hour.
5. Stick to fry after feeding the pond. The production practice of fry feeding shows that if the fry is fed 1 or 2 boiled egg yolks or feed yeast before entering the pond, it would be better if the rotifers can be fed. The survival rate or growth rate of the fry is significantly higher than that of the non-feeding fry, so many Locals insist on fry feeding after the pond. After the fry arrives, feed it with cages and re-enter the pool. When the seedlings are taken in the cage, the fry heads are generally of a strong constitution and the individuals are larger. The shark's fry is of a poorer constitution and the individuals are smaller, so that the fry of the individuals with different size and body strength can be basically separated. In order to avoid individual large and strong fish in the feeding process, the small and weak fries are excreted, and gradually form size differentiation. However, oxygen should be strictly prevented in the cage during the operation to avoid loss.
6. When the fish is under the pond, it is necessary to select the deep water and keep the seedlings close to the water surface. According to experiments, fry from the height of 30 cm into the water, can damage 5% to 10%; from the surface of 60 cm high, the fish damage rate of up to 20% to 30%. Therefore, the fish must enter the pool must pay attention to the slow release, the fry do not leave immediately after stocking, to wait for the fry spread into the pool and then leave, such as the discovery of the fish seed dense integration group, to use the water droplets to gently spill, make it scattered Swim into the pool. When it comes to windy weather, it is necessary to enter the pool in the deep waters of the upper winds, so that the fry will not be injured by the wind when it is blown to the pool slope or to the bottom of the pool.
7. The same pond should be stocked with the same species of fish fry with the same specifications, and try to get a full foot, so as to avoid the big fish eating small fish and out of specification. The fish fry with inconsistent specifications are stocked together, and the growth rate of big fry is much faster than that of the fry. Polarization is even more pronounced.
8. Self-hatching of the fry pond standard. See the two points of the eye and one point of the waist, and you can enter the pool when you can swim in parallel. Otherwise, feed it in time so that the fry will not die of hunger. The time of Xiatang is to choose a sunny day without wind and avoid wind, rain, or nighttime pooling.

Spring fish into the pond "eight notes"
When fish is released in the spring, due to the delicate body of the fry, little attention will be paid when it enters the pool, which may result in a greater loss, or even total destruction. Therefore, aquaculture farmers must pay attention to the following eight points when they enter the pond:
