Sea fish is a familiar dish of many families. To distinguish between fresh frozen fish and dead fish before processing, you should rely on the following tips.

Fresh fish eyes will be bulging and clear, the cornea will be elastic. Spoiled fish eyes will be sunken in, cloudy and the cornea will be wrinkled, even torn.

Gill

Fresh fish have pinkish red gills, stick to the star fruit flower, are not slimy, and have no foul smell. Meanwhile, spoiled fish have grey gills, do not stick to the star fruit flower, are slimy, and have a foul smell.

Fish meat

For fresh frozen fish, the body is hard, the meat is firm, and when pressed, it is elastic. When you press deeply into the fish's body with your finger, when you remove your hand, the dent immediately appears. On the contrary, fish that has been spoiled and then frozen has a soft, mushy body. When you press deeply into the fish's body with your finger, when you remove your hand immediately, the dent remains.

In particular, for fresh fish, when observing the cross-section of the fish, you will see a green line, possibly a different color, the meat is close to the bone, the bone is firm and has a special fishy smell. As for spoiled fish, the cross-section is not elastic, the meat is loose, and does not stick tightly to the bone.

Fin

If the fish is fresh, the scales will be shiny, tightly attached to the body, have no mucus, and no foul odor. If the fins of a rotten fish are frozen, they will be dull, not shiny, easily peel off the body, and will have an odor.

Fish belly

When you press your finger into the fish flesh to test, fresh fish flesh will be firm, elastic, and leave no imprint.
