1. Observe the position of the fish swimming in the fish tank
Usually, the fish swimming in the lower layer of the fish tank are the freshest; a closer look will also find that the gill lid rises and falls evenly when the fish breathes. Fish with poor freshness will swim on the upper level of the fish tank due to their poor breathing function, and will occasionally breathe close to the surface of the water. Some fish are still swimming, but a closer look will show that they are moving slowly, almost dying on the surface of the water.

Fresh fish, the eyes are clear and transparent, the eyeballs are intact, full and slightly convex; The gills are pink, the gills are tightly closed, and when opened, transparent mucus can be seen. The eye of the fish that is not fresh is collapsed, the cornea is bruised, and some are even incomplete, and the gills are purple-red.

Fish will inevitably have a fishy smell, but the fresh taste will not be too heavy. If the fishy smell is too large, it may be that the bacteria that breed make the taste heavier.
