1. Are tuna marine fish Tuna is a marine fish because they live in the ocean. The biggest difference between marine fish and freshwater fish is that they live in different waters. Tuna live in Atlantic, Pacific and Indian oceans, so they belong to marine fish. Tuna is a fish of teleost, perch and mackerel family. They are relatively large, with a thick head and a thin tail. They are not rich in fins on their bodies, and only have a short line of fins on their backs. Tuna swim very fast, and they can reach 160 kilometers per hour at the earliest.
2. Can tuna be farmed?Tuna can be farmed, but many farmed tuna are farmed for a short time. When breeding, wild small tuna is caught, and then raised for about one year before being put on the market for sale. The price of this tuna is not very high, and its meat quality is not as good as that of wild tuna.
If you want to completely cultivate, it is complicated. First of all, it is the water area. Tuna is relatively large, and it needs a large water area to ensure that they have sufficient living space. If it is stagnant water, we should also consider changing water. In addition, feeding and water temperature are difficult to control, so it is difficult to succeed in complete artificial farming.
