The crabs are raised by crab shells 3 times, after 20 to 30 days of feeding, to develop about 20,000/kg of crab (also known as bean crab). Crabs have high metabolic levels and fast growth. They need to feed a lot of high-quality bait. However, crabs have small individuals, poor resistance, and high requirements for bait. If they are directly put into lakes and rivers, it is just like putting fish fry directly into natural water bodies. The survival rate is very low (usually only 0.1% to 5%). Therefore, it is imperative to create an ecological environment that is invincible, has good water quality, and is well fed and palatable to promote its growth and increase the survival rate. The crab cultivation pond is a special cultivation pond set up to create this ecological environment.
