Tips for choosing fish:
1, first look at the activity of fish: generally healthy fish are highly active. Fish in poor health are prone to get sick and seldom swim. When we choose fish, we can choose those with high activity. This kind of fish tastes tight and delicious.
2. Look at the fish's eyes: If the fish is in good physical condition, the fish's eyes are black and shiny. On the contrary, if a dying fish has no brightness, it is very turbid. Dead fish takes a little longer and their eyes are white. We can know the fish's condition from its eyes.
3, look at the fish scales: good fish scales are very shiny, very smooth, no protrusions. Many dying fish have not finished eating their scales. We also need to see if there are parasites or something on the scales. Don't buy it if you have parasites.
4. See if the dividing line of the fish is clear: We can see if the dividing line between the fish back and the fish belly is clear. If it is clear, it means that the fish is in good health and worth buying. If it is not clear, it means that the fish is dying or already dead.
5, look at the fish gills: normal and fresh fish gills are very bright red, if the fish gills are dark red, this means that this fish is not fresh. It is also important that if fish have parasites, so will their gills. We can evaluate whether this fish is worth buying by looking at its gills.
