What are the correct methods for farming puffer fish?
Although puffer fish are poisonous, their flesh is extremely delicious. This has made puffer fish farming a popular project in recent years. Many people see the output of puffer fish but do not understand its farming process, and thus blindly start farming without correct farming management techniques, which often leads to farming failure. Since the cost of farming puffer fish is not low, farmers suffer serious losses. So how should puffer fish be farmed correctly? Let us take a look together.
1. Feeding of bait
After puffer fish are stocked, their feeding ability is related to the ambient temperature. When the ambient temperature is 15°C, puffer fish can feed normally, so at this time we should put out bait. Feeding should be done at fixed points and in fixed amounts, so that the puffer fish will consciously come to eat at the right time. When the water temperature is below 12°C, the feeding ability of puffer fish declines as the temperature drops. When the water temperature is below 10°C, puffer fish stop feeding and enter a hibernation state.
2. Water quality management
The water must be changed before overwintering. Disinfected pond water must be used to farm puffer fish, and oxygen must be continuously supplied. In winter, when the water temperature is too low, puffer fish stop feeding. During this period, the amount of water changed accounts for about 20 percent of the total pond water volume. Oxygen should be supplied at regular times, for half an hour each time, with an interval of half an hour. Oxygen must be supplied to the puffer fish every night to prevent them from suffocating due to lack of oxygen.
3. Prevention and control of diseases
1. Because fish are raised in dense environments, once disease strikes it is serious. In winter, the density of farmed puffer fish is too high, which very easily triggers disease, so we must prepare in advance.
2. Before stocking the fry, the fry must be disinfected to kill parasites lurking on the surface of the fish and bacteria on the pond bottom, preventing wounds from appearing during the growth period of the puffer fish and allowing bacteria to invade. Under normal circumstances, puffer fish must be disinfected every 15 days using antibiotics and some other disinfectants. Diseased fish should be promptly removed and treated in isolation to prevent the pathogens from infecting other normal fish.
3. In addition, to enhance the constitution of the puffer fish, we can mix an appropriate amount of antibiotics into their bait for feeding, improving the disease resistance of the puffer fish.
