1, the live fish that can be bought are turbot, red perch, pomfret, baogong, mussel and grouper. And these are farmed fish. The feed of pomfret is artificial granules, and whether the ingredients of granules contain toxic substances is unknown, but the mortality rate of cultured pomfret is very high. Others are mainly dead fish, dead shrimp and dead crabs. Antibiotics are added when you get fish disease. The meat is very thick. Personally, it is not good to eat too much.

2. There is Shi Jiugong who can be bought alive. This is a good marine fish that is also wild. Although it is not big, it tastes delicious. Buying a stone nine male and buying a bright color also means good water quality. Black nineteen, please don't choose, the water quality is not good, and the heavy metal content is definitely not low, such as in Shekou area.

3. In the seaside vegetable market, there are black stands, yellow feet stands, red stands, wild stone nails, wild sesame spots, mud dragons and so on that can be bought alive. Vertical fish are generally wild, but there are a few cultured fish. The wild black vertical tail is light blue, the yellow feet are pale, the front crucian carp and tail are yellow, and the red vertical body is light red with stars. These are the best marine fish. Wild stone nails and mussels are bright red, dark black or light yellow. Mud fierce is generally wild and tastes good. Mud fierce with good water quality is close to the color of seaweed, and its body is flat and fierce. Choice of chilled marine fish
