Detailed Explanation of Tuna Artificial Farming Methods and Technical Key Points

Tuna is a relatively precious marine fish with excellent taste and rich nutrition, and it is especially popular in countries such as Japan, the United States, and the United Kingdom. The tuna on the market still mainly comes from wild sources. Because tuna's economic value is very impressive, many people have been constantly exploring tuna artificial farming techniques, but so far there has still not been any particularly major breakthrough. Today we will mainly learn about simple tuna farming methods, and we hope you will enjoy them.

1. Farming Preparation

Tuna farming is relatively complex, and the current artificial farming techniques are not yet fully developed, so full preparation must be made before farming, otherwise it will be very difficult to keep them alive. Tuna is mainly farmed through cages. First, we need to choose cages of relatively good quality. Second, choose a suitable water area, then disinfect the cages before placing them in the water. Also, establish a red tide warning system in the selected water area. Finally, you can go and select the fry.

2. Seed Selection

Tuna fry are relatively precious, and because of the issues with farming techniques, we should be even more careful and cautious. When selecting the fry, carefully observe whether the tuna's body shape, scales, gills, fins, eyes, tail, belly, and other parts meet the standards (for specific standards, please consult). Then put food in and observe their feeding situation, and select robust fry free of disease for farming.

3. Fry Stocking

Before stocking, we need to disinfect and sterilize the tuna, because no matter what, the purchased fry will always carry more or less bacteria on their bodies. If directly stocked, they will pollute the water quality and cause all the fry to be harmed. So at the very beginning, they can be soaked in a special tuna disinfectant solution for about one hour, and after the bacteria have been cleaned away, they can be placed into the cages for farming.

4. Feeding Management

Tuna is a relatively delicate fish. Although it tastes excellent, it is not easy to keep alive, so feeding management is also very important. We need to understand tuna's living habits and reasonably choose bait according to how much tuna likes the food. Then, feed them at fixed locations at irregular times each day. Generally, feeding about three times a day is enough. If the selected feed is reasonable and the farming method is scientific, artificially farmed tuna will grow at least about two times faster than wild tuna, thus greatly shortening its growth cycle. This is also an advantage of tuna artificial farming.

5. Daily Management

Tuna's daily management mainly includes water quality management in the farming area, cage hygiene management, pest and disease management, and prevention of natural disasters. Tuna has very high requirements for water quality, so we must frequently inspect the water quality around the farming area and promptly purify the water quality when pollution sources are found. At the same time, tuna also has very high requirements for its living environment. We need to clean and disinfect the cages irregularly, and after feeding, promptly remove the food residue from the water to avoid polluting the water quality. For tuna, pest and disease control is mainly based on prevention, and an appropriate amount of antibiotics can be added to the feed. As for the prevention of natural disasters, we need to constantly pay attention to weather changes and adjust the cages in time.
