Naturally growing river crabs are generally burrowing or secluded. When the food is abundant and full, they often live in caves in order to avoid predators. When burrowing conditions are not available, they hide in gravel or grass.
River crabs usually prefer to live in rivers and lakes with clean water and abundant aquatic plants, and when they are in ponds, they often hide in the silt at the bottom of the pond. River crabs lie dormant at night, settle down when the bait is abundant and the environment is suitable, and once mature, they abandon their burrows and leave. River crabs grow in freshwater and reproduce in seawater.
After entering fresh water, crab seedlings generally live in rivers and lakes with abundant bait for about 18 months, and their gonads gradually mature. Mature river crabs begin to spawn in the offshore areas where sea and fresh water mix in late autumn and early winter, which is known as reproductive migration. Soon after mating, the female crab can lay eggs, which are attached to the female's abdominal limb hair in bunches and accumulate on the abdomen until hatchlings hatch.
This type of crab is called "egg-holding crab". River crabs can lay tens of thousands to millions of eggs at a time and can lay 2-3 times. In nature, fertilized eggs can only emerge after 4 months, and the hatching rate can reach about 90%.
The newly hatched larvae are small and shaped like daphnias, called flea-like larvae. The flea-like larvae have five molts and grow into crab seedlings (big-eyed larvae) in about 35 days, and the crab seedlings molt again to become larvae. The crab that has just shed its shell is called the soft shell crab, it is unable to feed and defend against the enemy, and the shell gradually hardens after 1-2 days, and then it gradually moves, and the crab body increases significantly after the shelling.
After the crab reproduces, its body quickly ages and dies. The feeding habits of the river crab are very mixed, it eats both meat and vegetables, and likes to eat fish, shrimp, snails, worms, earthworms, insects and their young and other animal foods, and also eats the same kind of injured or just molted shells, and the egg-holding crab also takes eggs as food when it is hungry. In the natural environment, most of the aquatic plants that river crabs can easily obtain are aquatic plants.
River crabs are very voracious, eat a lot of food, and have a strong digestive ability. When food is abundant, you can eat a lot, and when there is no food, you will not starve to death if you don't eat for a few days or even a month, because after eating, the excess nutrients will be stored in the liver, and the "soft shell crab" that has just been shelled is the nutrients stored in advance to maintain life. During the wintering period in the burrow, food intake is stopped or reduced.
River crabs are not only gluttonous, but also have a habit of grabbing and being aggressive. In order to compete for a good meal, they often kill each other.
