1. Meitong fish is a deep-sea fish. It costs about more than 20 yuan per pound. The specific price depends on the market conditions. It is similar to small yellow croaker.

2. Plum fish and small yellow croaker are not easy to preserve, and the taste of the fish will be much worse over time.

3. When buying these two kinds of fish at the market, you must look at the eyeballs and gills. The eyeballs are full, the cornea is transparent and clear, the gill cover is tight, and the gill color is bright red, indicating that the fish is fresh. Like other fish, if the scales on the fish's body are easy to fall off, are incomplete, and have broken skin, it means the fish is not fresh. In addition, you can also touch fish. The flesh of fresh fish is firm and elastic, and it can recover immediately after being pressed with your fingers, and the head and tail will not bend when you hold it in your hand. If the fish has been dead for a long time, the fingers will be loose and soft. When pressed with the fingers, a dent will appear and it will not rebound.
