Cultivation methods of silverfish fingerling

Silverfish many people may not be familiar with it, it is a translucent fish, the body is relatively slender, and salmon is very similar, some people call it noodle fish. Silverfish is one of the four famous fish in China with high economic value. it is mainly distributed in Poyang Lake, Dongting Lake, the Yangtze River and Taihu Lake. So today we are going to learn how to cultivate silverfish seedlings and how silverfish are raised.

1. Pond preparation

The best pond for silverfish fry culture is Laokou pond, the nearby water resources should be sufficient and pollution-free, there are wind shields around the pond, good lighting conditions, and it is convenient to change water. Then pull the net in the pond, properly clean up the mud at the bottom of the pond, then disinfect and sunburn the pond, and finally inject new water and put in the appropriate rotifer resting eggs for cultivation, which can provide some bait for the silverfish. After putting in the rotifer resting eggs, you can't release the seedlings until at least two weeks later, when the water depth is preferably 60 centimeters.

2. Seed and seedling selection

We can choose and buy silverfish seedlings from regular breeding bases, which is the simplest way. We only need to know the local silverfish breeding situation and choose robust, consistent and high-quality seedlings to raise them. Secondly, we can also cultivate our own, collect mature parents from natural waters, then carry out artificial fertilization, and then incubate in still water for about a month to cultivate silverfish seedlings. And the hatching success rate of this way of raising seedlings is still very high, more importantly, the varieties are relatively pure, and the survival of breeding is also higher.

3. Seedling stocking

Our general habit when stocking is to wait for the fry to be cultivated and raised for a period of time and then put into the culture pond, so that the survival rate of culture will be relatively high. However, the silverfish is different from other fish. It is best to put the eggs in the culture pond about a week before the fry hatch, so that the survival rate of the silverfish will be higher. The second is to pay attention to the density of stocking, generally, it is best to put 20,000 fertilized eggs in one mu, so as to avoid excessive density and affect the normal growth of silverfish. Finally, at this time, the water level in the pond should be slightly deepened, usually no more than 1.5 meters.

4. Cultivation technology

The fry cultivated mainly feed on rotifers. If the eggs hatch and wait until the fry begins to eat and there is not enough bait, then the fry will die, which is why we have to put the rotifer before breeding. Secondly, when we cultivate fish fry, we also need to ensure the fertility of the water body, which can improve the content of plankton in the water and ensure adequate bait. In addition, during the seedling period, we also need to fertilize frequently and reasonably control the water temperature to adjust the water level to about two meters. After the fry fully adapt to the environment of the pond, they can be cultured according to the standard of adult fish breeding.

Silverfish breeding work is actually very simple, and there is no great technical difficulty, generally a little experienced farmers can complete. The editor gave you a brief introduction to the cultivation methods of silverfish seedlings above. If you still don't understand, you can leave a message and consult.
