Seaweed is one type of marine algae that thrives in seas, oceans, and even some freshwater environments. Unlike terrestrial plants, it lacks typical roots, stalks, and leaves. Instead, its fronds absorb nutrients directly from the water. Seaweed, which can be green, brown, or red, is a vital component of marine ecosystems because it provides food and habitat for a wide range of marine species.

The market for seaweed farming has become more diversified as a result of government support for ecologically friendly methods and technological advancements in seaweed cultivation, as well as rising consumer demand for seaweed in food, nutritional supplements, and other industries.
