Selection of water quality: choose brackish water or fresh water to raise puffer fish.
Stocking fish: In order to ensure the quality of fish species, authentic fish species should be selected, and varieties with strong physique, no disease and no pain, small specification difference and strong traceability should be selected as the main breeding objects.
Domestication and feeding: puffer fish should be domesticated properly during the breeding process. After domestication, you can feed some broken fish, shrimp or snail meat, which can be used as open feed for puffer fish.
Then domesticate them and gradually adapt to the environment and bait. When they gradually adapt, mix artificial feed into the bait and gradually increase the amount until they finally eat artificial feed completely. The bait is mainly eel, and it should be positioned, timed, quantitative and qualitative when feeding. Usually feed it twice a day.
Water quality control: puffer fish is a kind of fish that requires high water quality. It likes clear and clean water. Fresh water should be added irregularly according to the color, quality and transparency of water, as well as the growth rate and feeding situation of puffer fish.
Water needs to be changed once a month to improve the water quality. The growth temperature of puffer fish should not be lower than 9 degrees or higher than 32 degrees, so we should always pay attention to the change of water temperature, pay attention to timely heating and cooling, and observe the change of dissolved oxygen. If oxygen is insufficient, inject oxygen in time.
