Crayfish selection

Look at the size. Buy crayfish of the same size. The crayfish produced by artificial legal farms are even in size and can be purchased with confidence. However, wild crayfish with poor growth environment vary in size and are mixed with old and young, so it is best not to buy them;

Look at the color. Buy crayfish that have just grown up. Red has a natural and healthy luster. Lobsters with black red or iron blue in red are lobsters that absorb more harmful substances, so it is best not to buy them;

Third, look at the fluff. Buy white and tidy crayfish with fluff and claws in the abdomen, which are basically raised in clear water;

Fourth, look at the "texture". Crayfish as elastic as nails, just grow up and change their shells, suitable for purchase. If you touch the shrimp shell with your hands, it is undoubtedly an old lobster and should not be bought.
