The red eye of golden pomfret does not necessarily indicate the freshness of the fish. In some cases, after the fish dies, the capillaries in the eyes will be congested, which will cause the eyes to be red, but this does not mean that the fish is fresh. In addition, some golden pomfrets may contract due to heat expansion and cold contraction or capillary contraction after freezing, and the red part may be more obvious after freezing, but this does not mean the freshness of the fish.

To judge whether golden pomfret is fresh, we can observe the appearance and gill color of the fish. Fresh golden pomfret usually looks shiny, with intact scales and red or pink gills. If the gills are dim or lose color, it may be a sign that the fish is not fresh. For frozen golden pomfret, the freshness can be judged by observing the eyes and scales of the fish, but the best way is to let the merchants provide samples for testing.

In a word, judging whether golden pomfret is fresh or not depends not only on the phenomenon of red eye, but also on the comprehensive evaluation of fish appearance and other characteristics.
