Culture conditions of puffer fish

Ponds: puffer fish should be raised in ponds with sufficient water sources, no water pollution and little change in water temperature. Fish stocking: choose puffer fish species with strong physique, no disease and little difference in specification, and need to disinfect the fish before stocking. Domestication and feeding: first, fresh meat is used as open feed, and artificial feed is added after gradually adapting to it. Water quality control: strict water quality requirements, the need for a big change of water every month, timely injection of oxygen into the reservoir.

I. the choice of ponds

1. The ponds for raising puffer fish should first choose places with sufficient water sources, no water pollution, and little change in water temperature.

2. If you choose brackish or freshwater aquaculture, it is easier to lift water and build a pond not far from the route.

3. There can be water leakage and seepage at the bottom of the pond, and the pond should be kept away from noisy places and keep quiet. For example, choose places far away from urban areas, factories, etc.

4. But it is also necessary to ensure convenient transportation and communication, which can effectively withstand the impact of storms or torrential rain.

II. Fish species selection and stocking

1. In order to ensure the quality of puffer fish, we should choose authentic puffer fish species with strong physique, no disease, little difference in specifications and strong traceability as the main breeding objects.

2. After purchasing the fish, the fish should be packed in plastic bags and transported with oxygen during the transportation of the puffer fish.

3. Under normal circumstances, fish species about 4 cm long can hold about 120 fish in each bag and can be transported for up to 8 hours, with a survival rate of at least 90%.

4. The fish species should be disinfected before stocking, and with the growth of the fish body, the fish should be caught big and small, and sparse culture should be carried out.

3. Domestication and baiting

1. Puffer fish should be properly domesticated in the process of puffer fish culture. after domestication, puffer fish can be fed with fresh meat such as minced fish, shrimp, snail meat and so on.

2. Then domesticate, so that the puffer fish can gradually adapt to the breeding environment and bait, wait until they gradually adapt, mix artificial feed in the bait, and gradually increase the amount, until finally completely eat artificial feed.

3. The bait is mainly eel, which should be positioned, timed, quantified and qualitatively fed. Usually take food twice a day.

IV. Water quality control

1. The growth of puffer fish has great requirements on water quality. It likes clear and clean water. So aquaculture ponds should add new water irregularly according to the color, water quality, transparency, growth rate of puffer fish, feeding conditions and so on.

2. Puffer fish ponds need to change water once a month to improve water quality.

3. The minimum growth temperature of puffer fish should not be lower than 9 ℃ and the highest should not be higher than 32 ℃, so we should always pay attention to the change of water temperature in the pond and pay attention to heating and cooling it in time.

4. it is also necessary to observe the change of dissolved oxygen in the pond and inject oxygen into the pond in time when there is insufficient oxygen.
