Abstract

Seaweed farming emerges as a sustainable and diverse means of subsistence for coastal fisherfolk in India, presenting economic opportunities while addressing environmental challenges. This study highlights the importance of seaweed cultivation in Tamil Nadu, India, as a strategic response to climate change and for generating carbon credits. Globally, seaweed output was 35.1 million tonnes, valued at 16.5 billion USD in 2022. In Tamil Nadu, 5,000 families annually harvest 47,000 tonnes of seaweeds, including key species like Sargassum and Turbinaria. Kappaphycus alvarezii, a carrageenan-producing red alga, experienced a peak production of 1,500 tonnes in 2012-13, declining to 400-500 metric tonnes annually. Despite challenges, over 2,000 families engage in seaweed cultivation. The study explores the Bamboo Raft Method, using hollow bamboo poles to construct 12’x12’ rafts. Seedlings from robust plants are transplanted onto seaweed-adorned ropes, forming rafts grouped and anchored in shallow water. An optimal configuration involves 400 rafts in a one-hectare area, ensuring effective seawater circulation. This research provides insights into seaweed farming practices and challenges, contributing valuable knowledge for sustainable coastal resource management
