43-46Systematic studies on C, N, P and their atomic ratios (C:N, N:P and C:N:P) have been reported in the seaweeds of Visakhapatnam coast. Variations in these components have been related to the position of algae in the intertidal zone, ambient medium concentration, nature of the species and class. While higher C:N ratios compared to other Indian seaweeds are attributed to nutrient enrichment in the ambient medium, lower N:P ratios are believed due to preferential accumulation of P over N
