Precautions for eating fish

1. Do not eat fish that is too red or too white. Depending on the species, fish can be divided into red-fleshed fish like tuna and white-fleshed fish like hairtail. However, if the color of the fish is too bright red or bright white, it is most likely due to the dye.

2. Choose someone who is "eight cents big" in size. The size of the fish determines its taste and safety. If it is too small, the fish has not grown up and matured, the meat is not tender enough, and there will be too many fish bones. If it is too large, it means that the fish is old, the meat is rough, and a lot of harmful substances may have accumulated in the body. Therefore, when buying fish, it is more appropriate to choose fish that are about "eight cents large" in size. For example, carp and Wuchang fish weigh 1 and a half kilograms, crucian carp weighs 0.5 kilograms to 1 kilogram, and grass carp weighs 4 to 5 kilograms.

3. Do not buy fish with cloudy and collapsed eyes and gray gills. When purchasing "chilled fish", you should first observe its eyes and gills. Fresh fish have full eyes, clear and transparent corneas, and clear and bright red gill filaments. Secondly, the eyeballs of fresh fish are not full, the corneas are wrinkled and slightly turbid, sometimes the eyes are bleeding and red, and the gills are darkened to gray-red or gray-purple. The eyeballs of rotten fish are collapsed or shriveled, the cornea is shrunken or ruptured, and the gills are brown or off-white.

4. It is best not to eat fresh fish immediately. Kill the fish now and release it before eating. The quality of freshly slaughtered fish is not the best, because the fish will undergo a "deacidification" process and needs to be left for a period of time to become more delicious. Small fish such as grass carp and silver carp should be refrigerated immediately and cooked after 2 hours; while large fish need to be refrigerated for more than 2 hours.
