How to choose blue crabs

Many friends like to eat crabs, but they are troubled by how to choose crabs because they think choosing crabs is a very difficult task. When selecting blue crabs, you can first look at the crab shell. You should choose some shells that are black-green and have a certain brightness. Then look at the belly button and choose those with a protruding belly button. Such blue crabs have fat and roe.

1. Look at the crab shell. Those with a dark green shell back with a shiny luster are thick and strong; those with a yellow shell back are mostly thin and weak.

2. Look at your belly button. People with protruding belly buttons are usually fat, while those with sunken belly buttons are usually not fat enough.

3. Look at the crab legs. Crabs with dense hairs on their legs are relatively strong, while crabs without hairs on their legs are soft and weak.

4. Look at the fullness. You can pinch the crab legs with your hands to see if they are plump, which can also help you pick good blue crabs.

5. Check the gender. Female crabs are the fattest and have plenty of roe in the eighth month of the lunar calendar, while male crabs are the most fragrant and have more fat in the ninth month of the lunar calendar. However, the season for eating blue crabs is relatively short, with October and November being the best months, while female crabs are best eaten in September of the lunar calendar.

6. Look at the vitality. Turn the blue crab over with its belly facing up. If it can quickly turn over using its stinging springs, it has strong vitality and can be preserved. If it cannot turn over, it has poor vitality and cannot be stored for long.
