Porphyra red algae are not found in Indonesia because Porphyra live in a subtropical climate.

This red algae grows a lot in the waters of Japan, China and Korea.

Therefore, many foods use nori from these three countries.

Cultivation of red algae for nori is carried out in summer.

In autumn when the sea water temperature is around 20 degrees Celsius, nori cultivation waters are installed with hooks to catch red algae spores.

Installation of spore hooks is carried out in water areas where nori naturally grows.

The red algae spores are then moved to areas of cultivated waters which are closer to the coast for easy monitoring.

Red algae will grow rapidly in autumn conditions.

Harvesting can be done after the red algae are mature.

Algae that are ready to be harvested are marked with dark red-brown or purplish sheets or thallus.

After the first harvest, algae can still be harvested repeatedly with a 10 day rest period.

After that, the algae is processed into nori by grinding and pressing.
