Algaculture

Algaculture is the practice of growing seaweed in the ocean or in a controlled environment like a tank or large pool. It is done for many different reasons, including food production, medicinal use, and for use in cosmetics. It is important for protecting coastal areas from erosion and helps to filter water, making it healthier and cleaner. Algae is also used as a natural fertilizer and a food source for many animals and fish, and is often harvested to be used in food products like sushi.
