Caridina multidentata (Amano shrimp) is one of the native species in Taiwan and Japan. Like most indigenous shrimp in Taiwan, it eats algae as its main food. Its ability to eat algae is better than other Atyidae species, so it is regarded as an indispensable "Algae shrimp", which is capable of removing algae effectively and maintaining the ecological balance in aquariums. Currently, Taiwan is the main producer of Amano shrimp. However, the wild species population is declining because of the large amount of human fishing. In order to protect the sustainability and balance of Taiwan's wild resources, we have cooperated with shrimp-breeding farms to develop artificially-bred Amano shrimp, which not only reduces the captured pressure on the wild species but also provides high-quality shrimp to supply the market demand.
