Breeding techniques of puffer fish

Puffer fish, also known as bubble fish, puffer fish, when in danger, its abdomen will inhale and expand, like a big bubble named. Its muscle is as white as frost, the meat is fresh and tender and delicious, the content of protein is extremely high, the nutritional value is high, it often appears on people's dinner table, is deeply loved by consumers, and the prospect of breeding is excellent. But during the puffer fish seedling period is relatively fragile, a little carelessness will lead to a large number of seedling death, let's learn about its seedling technology.

1. Breeding in a special pond

Puffer fish seedlings are small and tender, and their adaptability to the environment is poor, and external stimulation is not conducive to its growth, so it is necessary to raise puffer fish in a special pond and clear the pond before raising. Drain all the water from the pond, use the sun to bleach, remove the silt from the pond, inject 10-20cm, sprinkle quicklime in the whole pool for disinfection, generally use 100kg quicklime per mu, dissolve it with water, and sprinkle it throughout the pool while it is hot. After one week of disinfection, the seedlings can be released and raised when the toxicity is eliminated.

2. Cultivate water quality

One step should be carried out in the release of seedlings, that is, to cultivate water quality, and when disinfecting for 3-5 days, apply fermented organic fertilizer or manure to the pond traditional Chinese medicine, so that the water quality becomes fertilized, applying 150-200 kg of organic fertilizer per mu, waiting for the water color to turn yellowish green or brown. This water quality is not only conducive to the growth of puffer fish seedlings, water fertility is better, will breed a large number of organic organisms, and improve a large number of natural bait for puffer fish growth.

3. Reasonable secret storage

When the puffer fish goes into the pond, pay attention to the change of the water temperature. The water temperature of the pond and the water temperature temporarily raised by the puffer fish should not exceed 2 degrees, otherwise the water temperature will change greatly, which will cause puffer fish seedlings to catch a cold, resulting in a large amount of water temperature. So the time to release seedlings should be grasped, if the water temperature difference is large, you can keep injecting water in the temporary breeding place, so that the water temperature is similar to that of the pond, and the water temperature difference is less than 2 degrees in the seedling pond. When releasing seedlings, we should also pay attention to the method and density. when releasing, we should stand in the upwind of the fish pond and slowly put the seedlings into sugar, generally 12-150000 seedlings per mu.

4. Input and feeding management

Puffer fish seedlings have less mouth shape, so in the early stage, they are allowed to feed on the organic organisms in the water. After the cultivation of water quality, the natural bait in the water can be used for their growth. Half a month after the seedlings are released, they can be fed with soybean milk, usually once in the morning and evening. 50 kg per mu. It can be fed after one month, and the feed is made of bean cake, bran bran and distiller's grains in proportion. It can also be fertilized in time to maintain water quality fertility and supply sufficient natural bait according to the change of water quality.

5. Disinfection and disease prevention

The resistance of seedlings to disease is low, once the disease occurs, it will spread to the whole fish pond at a very rapid rate, and cause a large number of deaths. So to do a good job in daily disinfection, especially food farms, nets, feeding tools, etc., to use bleach for disinfection, and the pond to use quicklime for the whole pool disinfection, the use of quicklime 50 kg per mu. To strengthen the prevention and control of diseases, the common diseases of puffer fish seedlings are bubble disease, water mildew disease, Gill rot disease and parasitic disease.
