Seaweeds are macroalgae found along coastlines worldwide, classified into brown, red, and green algae. They serve as a foundation of aquatic food chains and are rich in nutrients like proteins, lipids, and vitamins. Seaweeds offer a wide range of applications in industries like food, cosmetics, and pharmaceuticals, and are known for their health benefits, including anti-cancer and anti-inflammatory properties. They also contribute to environmental sustainability by acting as carbon sinks and reducing eutrophication. In India, there is great potential for seaweed farming, with government support through programs like the Pradhan Mantri Matsya Sampada Yojana. Despite this, the current production lags behind available resources, indicating a significant opportunity for growth.
1. Seaweeds are macrophytic algae found in coastal regions globally, belonging to the Plantae kingdom.
2. Seaweeds are essential in aquatic ecosystems, serving as the foundation of the food chain.
3.They are rich in proteins, lipids, dietary fibers, vitamins (including A, K, and B12), minerals, and trace elements.
4. Seaweeds find applications in various industries including food, feed, cosmetics, agriculture, pharmaceuticals, and biotechnology.
5. Seaweeds have significant health benefits, including anti-cancer, antiviral, antidiabetic, and neuroprotective properties.
6. India has a rich diversity of seaweeds, with 844 species reported, but farmed production is currently low.
7. The government of India is promoting seaweed farming through initiatives like the Pradhan Mantri Matsya Sampada Yojana.
“”Seaweeds are known for their potent antioxidants, such as phlorotannins, carotenoids, and sterols, which may have neuroprotective effects against diseases like Parkinson’s and Alzheimer’s.
