How to judge whether the fish is fresh can be based on the following four points: 1. Smell the taste. Fresh fish, although a little fishy, but not so much, for fish that have died not long ago, the smell is heavier but not smelly, for fish that are going to spoil soon and fish that have gone bad, the fish is fishy and smelly.

6. Posture, fresh fish pick up the body hard and straight.

Judging the freshness of the fish, mainly to see whether the fish is alive and jumping If a fish is very fresh, then it itself is alive and jumping, you can't catch it if you touch it, if the fish is not too fresh, you will not move, if it is a burned fish, you can taste whether the taste is elastic, if it is powdered and glutinous, it means that it is not too fresh.

Look at whether the fish gills are bright red, whether the taste has a peculiar smell, whether the fish eyes are deformed and discolored, whether the fish scales are bright, whether the fish belly is bulging, etc. are the basic characteristics to identify whether the fish is fresh.

The freshness of the fish can be judged by the eyes and gills, which are fresh when the eyes are bright and the gills are bright red.

The gills must first be checked for bright red.
