How to raise puffer fish

Puffer fish, also known as bubble fish, belly fish, puffy fish, good fish, street fish, wax head and boat fish, when it encounters external danger, the whole body will float to the surface in a ball, and the small thorns on the skin will stand up to protect itself. In addition, it is also rich in protein and rich in nutrition. So how to raise puffer fish? Let's take a look at it.

I. Pond selection

First of all, the pond should have sufficient water sources, no water pollution, and little change in annual water temperature. Secondly, if you choose brackish water or freshwater aquaculture, you need to choose a place where it is more convenient to lift water, the route is not far, and the dust is low. Third, the bottom of the pool shall not leak. Finally, the pond should stay away from noisy places and keep quiet, but also ensure the convenience of transportation and communication.

2. Fish fingerling restocking

1. Choose fish species

In order to ensure the quality of fish species, it is appropriate to choose authentic species with strong physique, no disease or pain, little difference in specifications and strong traceability.

2. Transport fish species

After buying good fish species, they should be packed in plastic bags and oxygenated during transportation. Generally speaking, about 120 4cm fish can be packed in each bag and can be transported for up to 8 hours, with a survival rate of at least 90%.

3. Stocking matters

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

3. Domestication and baiting

In the process of breeding, puffer fish should be properly domesticated. After domestication, some minced fish, shrimp or snail meat can be eaten, and these fresh meat can be used as open feed for puffer fish. Then domestication, let it gradually adapt to the breeding environment and bait, and so on, they can gradually adapt to the artificial feed, and gradually increase the amount, until the final complete intake of artificial feed. Bait is mainly eel-based, feeding should be positioning, timing, quantitative, qualitative, generally twice a day.

IV. Water quality control

1. Add water and change water

Puffer fish is a kind of fish with high requirements for water quality. they like clear and clean water. Culture ponds should add new water irregularly according to the color, quality and transparency of the pond water, as well as the growth rate and food intake of puffer fish. A big change of water is needed every month to improve the water quality.

2. Water temperature control

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 heat it down in time. In addition, the change of dissolved oxygen should be observed, and oxygen should be injected in time when there is insufficient oxygen.

The above is the introduction about how to raise puffer fish. When breeding puffer fish, farmers need to pay special attention to the occurrence of diseases and inspect the pond regularly every day. If abnormal conditions are found, they should deal with them in time to prevent and control unnecessary losses.
