Its natural habitat has been collected for centuries by natives in large numbers in Lake SOSATEXCOCO in Mexico and Lake Chad in central Africa. After the research and report of Clememt et al. In 1962, it attracted the attention of many biologists all over the world and carried out a lot of research work successively. The results showed that it is a kind of high light energy conversion rate, high protein content
