The ICAR-Central Marine Fisheries Research Institute (CMFRI) has recently has been designated as a centre of excellence for Seaweed cultivation in India by the Department of Fisheries with the aim to enhance India’s role in the global seaweed industry.
About the Seaweed cultivation in India:
- Definition: Seaweed refers to various species of marine plants and algae, growing in oceans, rivers, and lakes.
- They are multicellular and macroscopic autotrophs.
- They are often referred to as sea vegetables.
- The term “seaweed” is misleading, unlike harmful weeds on land, seaweeds are essential to marine habitats and provide numerous benefits to marine creatures and humans alike.
Classification:
- Green (Chlorophyta)
- Brown (Phaeophyta)
- Red (Rhodophyta)
Characteristics of Seaweed (size):
- Microscopic Seaweeds: Includes phytoplankton that live suspended in water, forming the base of most marine food chains.
- Large Seaweeds: Such as giant kelp, which grow in abundant underwater “forests,” resembling towering redwoods.
- Medium-sized Varieties: Present in various colors including red, green, brown, and black, often washing up on beaches.
Applications of Seaweed:
- Nutritional Benefits: Rich in minerals (calcium, phosphorus, sodium, potassium) and vitamins (A, B1, B12, C, D, E).
- Health Benefits:
- Known for anti-inflammatory and antimicrobial properties.
- Used in cancer treatment.
- Manufacturing Uses:
- Seaweeds serve as effective binding agents (emulsifiers) in products like toothpaste and fruit jelly.
- Used as softeners (emollients) in organic cosmetics and skincare products.
- Agricultural Benefits: Enhances crop productivity through improved soil health and nutrient supply.
