Detailed Explanation of Key Points in Daily Management Techniques for Pufferfish Farming
In recent years, farming pufferfish has become one of the projects for people to make a fortune, because pufferfish meat is very palatable and is also quite good for human health. Those who have eaten it will linger over the memory of it, and it is one of the more popular fish species today. So now many people think that farming pufferfish has high economic value and follow the trend of farming it, but they do not have a correct management method, which leads to farming failure. So how should daily management be carried out when farming pufferfish? Let's take a look together with the editor below!
1. Bait Feeding
After the pufferfish are stocked into the pond, there are certain requirements for water temperature. At 15°C, pufferfish still have a certain feeding ability, and we should feed them at fixed times. In the early stage of stocking, let the pufferfish form a habit of eating at a fixed point. The bait should be wet pelleted bait, preferably made fresh and fed immediately. The general feeding amount should reach half of the pufferfish's body weight, at least twice a day. When the water temperature drops below 12°C, the pufferfish's food intake will drop noticeably. When the water temperature reaches 10°C, the pufferfish basically will not eat. At this time, feeding should be stopped and the water temperature should be increased appropriately. When feeding, let the pufferfish eat well and be full, and remove leftover bait in time to prevent water quality from being polluted.
2. Water Quality Management
When farming pufferfish, when entering winter and carrying out high-density overwintering work, it is necessary to maintain good pond water quality and try to use disinfected water for overwintering. As also mentioned above, if the water temperature is suitable, pufferfish can still eat, so bait still needs to be fed. During overwintering, all the pond water should be replaced and oxygen should be supplied continuously. When the water temperature is too low, the pufferfish will stop feeding. At this time, the water exchange volume can be reduced to about 20% of the pond water, with intermittent oxygen supply, at least half an hour each time, and the interval is also half an hour. Supply oxygen in time every night to prevent pufferfish from suffocating and dying due to lack of oxygen.
3. Fish Disease Prevention and Control
Fish disease is one of the most troublesome problems in everyone's farming process, especially during overwintering. When pufferfish overwinter, because the density is too high, diseases are very likely to occur. Before stocking the fingerlings, disinfection work should be carried out on them to clean off parasites and pathogens on the surface of the fingerlings' bodies. Prevent injuries during the growth process, which can infect wounds and give bacteria a chance to invade. During overwintering, prevention should be the main focus. Generally, every half a month, drugs such as antibiotics need to be used for surface disinfection. Fish found to be sick should be taken out in time and treated in isolated farming to prevent fish diseases from spreading and spreading further.
4. Pond Switching and Water Exchange
Exchanging water in the pond can reduce the amount of waste and pathogens produced in the water due to pufferfish metabolism, allowing the pufferfish's growth environment to be improved. Pond switching is beneficial for carrying out periodic comprehensive disinfection of the fish pond and removing harmful organisms and parasites in the pond. Improving the pond water environment can effectively reduce the incidence of fish diseases and increase their survival rate during overwintering. Generally, the pond is switched about once every 30 days, and it also needs to be switched once before overwintering, carrying out a comprehensive and thorough disinfection of the pond.
The above four points are the key points of daily management when farming pufferfish. When farming pufferfish, everyone must control the pond water temperature well, especially when the pufferfish are preparing to overwinter. Make preparations before the cold wave arrives, keep heating equipment ready at all times, and when the water temperature is below 12°C, immediately carry out heating work to control the water temperature at around 15°C and keep it constant.
