Cultivation method of "ginseng in water" baby fish

Baby fish, also known as Chinese giant salamander, is a kind of amphibian and a precious wild protected animal in China. In recent years, it has been used in edible and medicinal markets. So, what are the breeding methods for baby fish? Let's get to know it together.

1. Culture conditions

If it is an outdoor condition, you can build an aquaculture pond outdoors, if it is indoor, you can use an aquaculture tank or pond for aquaculture, and the aquaculture pond can keep running water or be equipped with an aerator. The size of the indoor pond can range from 1 square meter to dozens of square meters. Before stocking, you need to immerse the pond in water for a month, keep the PH value below 6.4, and the light should not be too strong.

2. Daily management

Pay attention to three principles when baiting: timing, fixed point, quantitative, baby fish like quiet and afraid of noise, like clear water afraid of muddy water, like dark fear of strong light, culture should pay attention to these habits as far as possible, usually regular baby fish and culture ponds for disinfection and disease prevention, pay attention to water temperature changes, summer water temperature is not more than 26 ℃, winter to prevent water temperature below 0 degrees.

3. Water quality regulation

The breeding baby fish should ensure that the water quality is clear and pollution-free, the dissolved oxygen content in the water is high, and the PH value is between 6.8 and 7.8. In the process of breeding, the residual bait and excreta should be removed in time, the water quality should be regulated regularly with quicklime, and the pool water should be kept flowing or equipped with aerator for a long time.

4. Temperature and light

The breeding baby fish should pay special attention to the water temperature. Exceeding its tolerance will cause the baby fish to hibernate or hibernate in summer. In the hot summer and cold winter, measures must be taken to cool or increase the temperature to ensure that the giant salamander has a suitable water temperature growth environment. Doll fish are afraid of light, and breeding farms should take measures to avoid sunlight.

5. Stocking density

The stocking density of the breeding pond should be determined according to the specifications of the baby fish and the factors such as water source, water body, bait and so on. in general, the stocking density in the seedling stage can be appropriately on the high side, which is convenient for centralized management. In the adult salamander stage, considering the large range of activities, strong feeding ability, coupled with mutual aggression, the stocking density should be reduced. Generally speaking, the stocking density is 60-100 tails / square meter in the seedling stage and 5-20 tails / square meter in the adult salamander stage. Try to put the size of the body together.

6. Feeding skills

The best feed is natural bait. Plankton, insects, meat, fish and shellfish can be fed once in the morning and evening, preferably around 7: 00 a.m. and 9: 00 p.m., and the feeding amount is 5-10% of body weight. When the water temperature is 16-23 ℃, the feeding amount should be increased, because at this time the growth rate of baby fish is accelerated, and the frequency and time can remain the same.

7. Guard against theft and escape

The dollfish has a particularly strong ability to escape, and its agile movement on land and in the water, so it must always pay attention to escape prevention, and all inlets and outlets of the breeding pond and the whole farm should be equipped with anti-escape facilities; because the dollfish has high economic value, we should also pay attention to anti-theft work when breeding.

8. Disease control

In the process of artificial breeding of baby fish, due to the influence of environment, bait and density, the morbidity and mortality of cultured baby fish are relatively high. in order to improve the survival rate of giant salamander, we must pay attention to the prevention and control of diseases on the premise of strengthening daily management.

The above is the doll fish culture method summarized by Xiaobian for you. I hope it can help you!
