Yinlong is a kind of high-grade tropical fish. The price of common silver dragon ranges from ten yuan to one thousand yuan, and the most valuable red-eye silver dragon sells for tens of thousands of yuan. The high-grade feeding experience of high-grade Yinlong is now introduced as a reference.
First, to prepare seedlings
1. Burn the boiler, control the temperature of the water tank in the fish room at 28°C, close the doors and windows, and prevent the temperature from falling. 2. Select the fish tank, install filter cotton, activated carbon, coral stone gas pump, water pump, add water to 20 cm, open and check the air pump to ensure normal operation, and adjust the cylinder temperature control rod to 28°C. 3. Quickly return the fish to the farm. 4. Prepare new water. Water temperature 25 °C, containing 1% salt, furacillin 2ppm.
Second, the seedlings require the fry to join the field immediately after the preparation of new water, remove dead and injured seedlings, re-oxygenation pack, observe and then put into the fish tank temperature adjustment after half an hour, put the seedlings into the tank after 1 hour.
Third, the breeding process
1. The specification of the fish tank is 126 centimeters and 48 centimeters, and 300 silver dragons can be placed. 2. Characteristics of fish fry Freshly hatched silver arowana has a small yolk sac. At this time, the egg yolk is mainly used as a nutrient, but from the second day it is necessary to start tame food. The yolk sac disappears about 7 days later. 3. Use live bloodworms to eat live bloodworms first with 3% salt, nitrofurazone 5 g / liter bath for 15 minutes and then feed, feeding with patience to one by one to feed, to eat in 20 minutes is appropriate. 4. The feed was changed within 10 days of feeding live bloodworms, and after 10 days it was changed to feeding quick-frozen blood bugs. The third month is gradually over-shrimp (seawater, freshwater shrimp can be), after the head and tail cut into the size of the appropriate diameter, can be fed after rinsing with salt water, with 10 days is appropriate, 20 minutes after each feed Remove the residual bait. 5. Number and timing of feeding In the first month, a total of 5 feedings were performed daily from 5 am to 10 pm; the second month was 4 times; the third month was 3 times; and the fourth month was 2 times. 6. Growth and Density The silver dragon grows faster, and its body length is about 6 cm to 7 cm when it enters the court; 12 cm for 1 month; 17 cm for 2 months; and 24 cm for 3 months. In the growth process of Yinlong, the stocking density must be adjusted in time according to its growth. It is best to screen it once a month. The first time is 150 tails/cylinder; the second is 70 tails/cylinder; the third is 25 tails/cylinder. Afterwards, either reduce the number or move into the vat. 7. The water depth at 1 month of age is 20 cm, 25 cm at 2 months, 30 cm at 3 months and then 37 cm to 40 cm. 8. Sewage, depending on the water quality, etc., absorbs the dirt every 3 days to 5 days, and then removes dirt from the bottom of the cylinder. Each time the water level does not exceed 5 cm, the sewage is sucked once a day from the second month. More than 5 cm water level. On the fifth to seventh days, filter cotton and activated carbon are washed once. 9. Strict control of pH, dissolved oxygen, temperature, etc. The pH is 6.8 to 7.2, the temperature is 28°C, the dissolved oxygen is 7 ml/g or more, the hardness is 9 to 10, and the corresponding measures are taken as soon as the change is found.
Fourth, disease prevention
1. After the silver dragon seedlings are placed in the tank, 2.4 million units of gentamicin sulfate per cylinder are used to disinfect the body of water to kill pathogenic bacteria and prevent water damage and damage caused by transportation. 2. At present, there is very little disease in silver arowana, and the survival rate of culture is almost 100%. If necessary, it is only necessary to prevent with an appropriate amount of antibiotics (chloramphenicol, oxytetracycline, tetracycline) every week.
