Both are a type of crab. Male sturgeons and female sturgeons that are not in the breeding season are called cabbage sturgeons, while female sturgeons in the breeding season are called red sturgeons. The main differences between red sturgeon and cabbage sturgeon are as follows:

1. Differences in growth period

The cabbage sturgeon, also called blue crab, belongs to the Crustacea family, Portunidae ( Aphrodisiacae), they like to live in burrows in the sandy bottom of shallow seas near the coast and at estuaries. They are ferocious and carnivorous, mainly eating fish, shrimp and shellfish. The red sturgeon is a female Scylla serrata during the breeding season. It produces red or yellow crab paste in its body, so it is called red sturgeon, also called red sturgeon.

2. Difference in appearance

The crab tail of the cabbage sturgeon is elongated and triangular, and the crab tail cover is thin and triangular, while the crab tail of the red sturgeon is spherical and the crab tail cover is Spherical in shape. In fact, the red sturgeon, as the name suggests, is its "red". Gently open the red sturgeon and look at the gap between the tail shell and the crab shell to see if the meat inside is red (be careful to see if it is fresh). , if it is red, it is a red sturgeon, if it is not red, it is a cabbage sturgeon.

3. The difference in nutritional value

The sturgeon not only has very high medical value, but also has high nutritional value. Vegetable sturgeon is very rich in protein, fat, amino acids and other trace elements. The paste of red sturgeon is more plump. Female sturgeons in the breeding season give birth to red paste and become "red sturgeons", which are also more nutritious.

4. Differences in market time Red sturgeon refers to the "female sturgeon" in the breeding season, so male sturgeons and female sturgeons not in the breeding season are both called vegetable sturgeons. In Fujian, red sturgeons are on the market around the Chinese New Year (January to mid-February), while vegetable sturgeons are basically on the market from July to December, and vegetable sturgeons in August and September are relatively cheap.
