How to keep whitebait? Common freshwater small fish farming methods

Whitebait is nutritious, and its nutrients are very easily absorbed by the human body. It is mainly available in the form of dried fish, has an excellent taste, and relatively few bones. Below is an introduction to the common freshwater small fish “whitebait” farming methods!

1. Farming preparation

Whitebait has high requirements for water quality. When building a pond, try to choose a place with sufficient water sources. After the pond is built, it must first be disinfected with quicklime, then the water should be drained out, and then an escape-prevention net should be laid in the pond to prevent the whitebait from escaping. Finally, add new water and wait to release the fish.

2. Fry selection

Choose robust and lively, active fry. Observe whether the belly of the whitebait is injured and whether it is relatively broad and even. Finally, select fry that meet the standards for stocking. During the transportation of the fry, an appropriate amount of oxygen enhancer needs to be added to the water tank, or oxygen supply equipment should be installed on the vehicle to prevent the fry from dying of oxygen deprivation during transport.

3. Fry stocking

Before putting them into the pond, we need to first thoroughly disinfect the fry, but it must be done quickly, otherwise the losses will be severe. After disinfection is completed, they must be put into the pond immediately, and the oxygen in the pond should be appropriately increased so that they can quickly survive.

4. Feed feeding

What whitebait loves most is fishy-smelling flour-based food, but fry that have just been put into the fish pond cannot be directly fed flour-based food, so at this stage we can plant some phytoplankton and aquatic plants in the pond, which can provide them with a certain amount of food. Then we can also pour plankton into the pond for feeding. After the fry have basically adapted to the pond environment, we can appropriately feed some processed feed, or fishy-smelling flour-based food, but the amount must not be too large, otherwise they will eat themselves to death.

5. Daily management

After each feeding, we need to remove the leftover food and food residue from the pond. This can prevent the food from becoming foul and prevent the whitebait from getting sick after eating spoiled food. Next, we need to observe the activity of the whitebait. If it keeps sticking its head out of the water and blowing bubbles, then the oxygen in the water is relatively thin, so we need to replenish oxygen in time. Then, if dead whitebait are found floating to the surface, they should be removed in time to avoid polluting the water quality. At the same time, check the reason they died. If it is disease, then the fish in the pond should be controlled and treated in time, which can effectively protect the normal growth of the whitebait.
