Why do we need to cultivate aquatic plants in crab farming?

The quantity and quality of water plants play an important role in the success or failure of crab farming. As the saying goes, "the size of crabs depends on water plants", which fully illustrates the important role of water plants in river crab farming. First, it can be used as part of the bait for river crabs, and it can also absorb sewage. At the same time, it can control the rise of pond water temperature, reduce the proportion of sexually mature crabs, and ultimately increase economic income. Secondly, it also has a certain stabilizing effect on the pH of water, and can be used as a habitat and molting place for river crabs, helping river crabs to shorten the molting time, reduce physical consumption and reduce the role of enemy killing and killing of the same kind, which relatively increases the yield. Thirdly, river crabs often walk on water plants, which has the effect of washing silt, making the crab body change from black to back grass and belly white, and also restore its original color characteristics of Chinese mitten crab. Cultivated water plants are generally peanuts, bitter grass, and verticillaster black algae, with a coverage of about 50-70%. Water plants transplanted and cultivated in crab ponds are generally not fertilized with manure, but chemical fertilizers can be applied appropriately. However, if the aquatic plants grow too vigorously or too densely, they must be cut off appropriately to prevent the strong sunlight in midsummer from killing the aquatic plants floating on the water surface and causing water pollution. This is a point that must not be ignored.

I am a beginner and I am planning to learn how to breed crabs, but I don't know what kind of grass to plant. Please give me some advice.

There are many varieties of aquatic plants suitable for breeding crabs, and mixed planting of multiple varieties is recommended, such as Vallisneria, Elodea, Hydrilla verticillata, Duckweed, Potamogeton microdentata, Potamogeton malaysianum, etc. These aquatic plants are rich in nutrients, tender, and have good palatability.
