How much is the price of tuna per jin? Attached picture

Tuna has different names in different places, and it is a kind of fish with large size and edible value. Because of its delicious meat and high nutritional value, many people began to catch and sell them, resulting in fewer and fewer wild ones, so now some places have begun to engage in artificial breeding. How much is the price of tuna per jin? What are the key points of artificial breeding? A picture is attached.

How much is the price of tuna per jin?

The price of tuna is relatively expensive compared with ordinary fish, and the price varies according to different parts, ranging from 400 to 1200 yuan per kilogram, that is, the price of tuna is about 200 to 1200 yuan per catty. Tuna prices are different in different fishing periods and in different port areas.

II. Key points of artificial culture of tuna

1. Culture preparation

Tuna culture is relatively complex, and the current artificial culture technology is not perfect, so before breeding must be fully prepared, otherwise it is difficult to feed. Tuna are cultured mainly through cages. First of all, we have to choose cages with better texture, then choose suitable waters, then disinfect the cages and put them in, or set up a red tide warning in the selected waters. Finally, you can choose the fry.

2. Fish species selection

The species of tuna are more precious, and at the same time, because of the problem of culture technology, we should be more careful. When choosing fish species, we should carefully observe whether the tuna's body, scales, Gill, fin, eyes, tail, belly and other places meet the standards (specific standards can be consulted). The second is to put food to see how they eat, choose strong, disease-free fry for breeding.

3. Fish fry restocking

We need to disinfect and sterilize the tuna before stocking, because the purchased fish fry always carry more or less bacteria anyway, and if they are released directly, they will pollute the water quality and cause damage to all the fry. So at the beginning, you can soak the tuna in a special tuna disinfectant for an hour or so, and after the bacteria are cleaned, you can put it into a cage for breeding.

4. Feeding and management

Tuna is a relatively delicate kind of fish, although it tastes great, but it is not easy to feed, so feeding management is also very important. We need to understand the living habits of tuna and choose a reasonable bait according to the tuna's love of food. The second is to put feed in a fixed place and irregularly every day, usually about three times a day.

If the feed selected is reasonable and the way of culture is scientific, then the growth rate of farmed tuna is at least twice faster than that of wild tuna, so it greatly shortens its growth cycle, which is also an advantage of tuna culture.

5. Daily management

The daily management of tuna mainly includes water quality management in culture area, sanitary management of cages, management of diseases and insect pests and prevention of natural disasters. Tuna has high requirements for water quality, so we enter the market to check the water quality around the culture area and find the pollution source to purify the water quality in time.

At the same time, tuna also has high requirements for the living environment, we need to irregularly clean and disinfect the cage, the second is to fish out the food residue in the water in time so as not to pollute the water. For tuna, the prevention and control of diseases and insect pests is mainly based on prevention, and an appropriate amount of antibiotics can be added to the feed. The prevention and control of natural disasters requires us to often pay attention to meteorological changes and adjust the cage in time.
