Wide and thick hairtail and water hairtail. Because hairtail in seawater is not very wide, and the meat is not very thick, because hairtail is almost absent all the year round, so hairtail is relatively large, probably not in seawater, but in mixed water, that is, fish in freshwater estuary. The color of hairtail in seawater is greener than that in mixed water, and the color in mixed water is whiter. Mixed water hairtail often has a particularly large bone spur.

How to choose hairtail well

Look at the eyes and buy hairtail. Be sure to buy small black eyes that look very transparent, which proves that the treatment is relatively fresh.

When buying hairtail, people who don't understand think that the bigger the wider the better, but it's not. Hairtail with wide head and thick flesh is generally imported hairtail, which doesn't taste like hairtail. Delicious hairtail, such as Zhoushan hairtail, is generally less than one meter and three to four fingers wide, which is the standard hairtail.

Looking at the fresh hairtail, the surface of the fish is complete, the silver scales on the surface will not fall off, and the epidermis can also be reflected. It's never wrong to take this hairtail home. If the silvery scales on the surface of hairtail fall off and there are metamorphic and necrotic parts on the hairtail, then such hairtail must not be fresh enough. If you bought it at the price of fresh hairtail, you must have been cheated.
