The difference between black tiger shrimp and mud shrimp

The morphological characteristics, origin, nutritional value and living habits are all different. The black tiger shrimp has a black-brown and khaki horizontal stripe pattern on its body and is widely distributed in Southeast Asia. The mud shrimp has a body color of khaki to brown, and its swimming feet are brown or red. It is mainly distributed in the coastal areas of Fujian, Taiwan, Guangdong and Guangxi in China.

The shrimp is hardy and omnivorous, but prefers meat. Adult shrimp can live in pure fresh water or seawater with a salinity of 35%, and is suitable for sandy and muddy bottoms.

The astaxanthin content of black tiger shrimp is about 20% higher than that of ordinary shrimp, which can significantly enhance the survival rate and spawning rate of shrimp, as well as the ability to resist harsh external environment.

How to keep shrimp fresh
