About

Pyropia is a genus of red algae in the family Bangiaceae. It is found around the world in intertidal zones and shallow water. The genus has folding frond-like blades which are either red, brown or green. Some Pyropia species are used to create nori, and are thus important subjects for aquaculture.

Where it grows

Pyropia grows in intertidal zones and down to 10 meters in some bodies of water based on clarity and substrate. It grows in large swaths, attaching itself to stones and shells, covering most of the bottom. Pyropia can be found globally in warm-temperate and extratropical [cool] waters.

Uses

Within the genus Pyropia multiple species are used for nori (edible seaweed), Pyropia yezoensis and P. haitanensis being most popular. It is a two-billion-dollar industry with most major growers located in China, Korea, and Japan.
