A new sector for rural economic growth is the seaweed industry, particularly in coastal districts. Along the entire coast of Tamilnadu, there is a total of 5048 hectares that might be used for seaweed farming. Around 1,15,150 MT of seaweed are now in demand in Tamilnadu. However, the actual estimated production is only 13,300 MT. The seasonal availability and prevailing market price of seaweeds were studied through personal interview among 285 respondents and major traders in coastal areas of Tamilnadu to explore the potential seaweeds to be utilized as livestock feed. It was found that Sargassum wightii, Turbinaria ornata, Gracilaria verrucosa, Gracilaria edulis, and Kappaphycus alvarezii were having the potential to be utilized in livestock feeds based on availability and prevailing market price. Further research is needed to identify the nutrient composition, plant secondary metabolites and level of economic inclusion levels of these seaweeds in livestock feeding.
