Seaweed have been extensively utilized in a food and as raw material for production of phycocolloids and phyto-supplements (soli, additives, fertilizers) besides investigating for pharmaceuticals, nutraceuticals and cosmetics use (Hanisak, 1998; McHugh, 2003).marine primary producers contribute at least 50% of world’s carbon fixation and 71% of the total carbon storage, macroalgae, being photosynthetic plants, use substantial amounts of atmospheric co2 for synthesis of organic biomass and has immense potential to abate climate change problems. Various species of marine algae also act as filters to abate clean the ocean (Kader et al., 2013). The large scale cultivation of seaweeds for bioenergy is yet another emerging potential with twin benefits of biological carbon capture and storage (Adam et al., 2012). Chang et al. (2011) also suggested that co2 emissions significantly. Thus, the systematic harvesting and legitimate practice of macroalgal primary production could play a remarkable role in carbon sequestration and reduction of greenhouse gas emissions.
