Tiger head shark, also known as axe head shark, is a kind of fish that Southeast Asian countries like to fish, mainly distributed in mountain rivers, rivers and other water bodies, is a small fleshy wild economic fish, many people like to be raised as ornamental fish, how to raise tiger head sharks?

1. Pond conditions: the suitable pond area for raising tiger head sharks is 2000-3000 fish, and the water storage depth is about 2000-3000 fish per mu. The suitable pond area for mixed culture of tiger head shark is 100 fish / mu.

2. Water temperature control: Tiger head sharks inhabit the middle and lower layers of the water body, and the suitable temperature for growth is 22-26 degrees. When the water temperature drops to 14-18 degrees, the activity will decrease, and shock will occur when the water temperature is 12-13 degrees. Therefore, cold shelter is usually built when breeding.

3. Stocking density: the stocking density of tiger head sharks should be determined according to the actual situation, usually 2000-3000 fish per mu of about 3-4 cm. When mixed with silver carp, grass and tilapia, 100 / mu.

4. Feed selection: Tiger head sharks do not have high requirements for feed, and the crude protein is more than 27%. According to the situation, water hyacinth and macaroni can be pulped and mixed with chopped corn and bean dregs.

5. Feed feeding: the feed of tiger head shark should be regularly, positioned, qualitatively and quantitatively, and the protein of compound feed should be more than 40%.

6. Water quality management: in the process of feeding, we should pay attention to the changes of water quality, change water frequently and feed less frequently to ensure the healthy growth of fish fry.

7. Disease prevention and treatment:

(1) rotten fin disease: the symptoms are that the fish's caudal fin and dorsal fin are congested and ulcerated, the diseased fish do not eat, and a large number of fish die. The cause is caused by infection bacteria, which is a serious infectious disease in the seedling stage. The pond water can be disinfected with 15 mg / L formaldehyde or 10 mg / L potassium permanganate or 10 mg / L 20 mg / L bleach, and antibiotics can be added to the mixed feed. Every thousand fish are treated with 30 tablets of oxytetracycline for 7 days continuously, and the diseased fish can be cured.

(2) White spot disease: also known as melon disease, the disease is easy to occur when the water temperature is 20-24 ℃. The disease is characterized by white spots on the body surface, empyema in severe cases, and emaciation of fish. It can be sprinkled with 0.1mg / L mercurous nitrate in the whole pool and repeated again after 3 days. The small melon insects will fall off automatically.

Generally speaking, tiger head sharks are easy to raise, as long as they build ponds, control density, feed well, and prevent and cure diseases.
