Fish Farming Technology in Fish Ponds

Lima Machinery is manufactuer of fish feed machines for fish farming as well as fish feed production business. We have different floating fish feed pellet machine to meet your production needs. Here is our some sharing fish farming technology.

1. Strong seedlings in the lower pond: When lowering the pond, you should choose high-quality fish fry with strong physique, neat specifications, and lively swimming. Only in this way can the survival rate of the fish fry in the lower pond be improved.

2. Safe dropping of the pond: Before the fry are dropped into the pond, it is necessary to strictly check whether the clearing medicine has completely failed. You can first put dozens of fish fry into the cage in the pond and observe for a day and night to see if there is any abnormality in the fry activity and feeding. If there are abnormal phenomena such as restlessness, floating heads, struggling, and swimming around, it indicates that there are still residues of clearing drugs. It should wait until its efficacy has completely disappeared before going down to the pond.

 3. Harmless lowering pond: Because the fry are small, their ability to resist the invasion of predators is weak. Before the fry are lowered into the pond, the whole pond must be pulled 1-2 times with a dense mesh net to remove the harmful insects and frogs in the water. Eggs, tadpoles, wild trash fish and other predatory organisms that may endanger the fry are cleaned up to ensure the safety of the fry in the pond.

4. Putting down the pond at the right time: Putting down the pond too early, the physique of the fry is too weak, the vitality is poor, and the survival rate is low. The yolk sac of the fry has been absorbed completely and the physique is poor, which is likely to cause the fry to die after they are put into the pond. The best time to go to the pond is 4-5 days after the fry are hatched, when they can swim freely and eat food.

5. Down the pond on sunny days: It is best to drop down the pond at noon on a continuous sunny day, when the fry adapt to the environment quickly and the survival rate is the highest.
 
 
 
6. Opening food of putting down : In the afternoon, two boiled egg yolks were fed to every ten thousand fry. The boiled egg yolks were wrapped with gauze, crushed, washed into egg yolk juice and fed to the fish. Feed another meal in the morning, increase the number of egg yolks to 4, and the seedlings will emerge from the pond at noon. To easy the feed praparing, you can choose Lima fish feed extruder or fish feed meal machine to make feed for fishes in different growing periods.

7. The same batch of lower ponds: each time the fry in the lower pond must be the same species of fry cultivated in the same batch. It is strictly forbidden to mix the fry of different sizes and varieties, which will seriously affect the survival rate of the fry in the lower pond.

8. Adjust the temperature of the lower pond: For the fry transported from other places, especially the fry transported from the nylon bag with oxygen, due to the large temperature difference between the water temperature in the bag and the pond water temperature, the nylon bag can be opened first, and the bag can be put into it. In the pond, add some pond water appropriately. After tens of minutes, put the seedlings into the pond when the temperature inside and outside the bag is basically the same.

9. Look at the pond under the wind: When there is wind, the fish fry should be placed in the upper wind in the lower pond. Do not put the fry in the downwind to prevent the fry from being blown to the pond and die.

10. Disinfect the lower pond: When the fry are discharged into the pond, try to use salt, potassium termagant and other drugs to disinfect the fry before being discharged into the pond.
