Description Seasonal variation of halides and their ratios were estimated in three brown algae, namely Cystoseira indica, Sargassum tenerrimum) and S. johnstonii from Porbandar and Okha Coasts. Halides were found to be higher in early stages of growth. The Br:F ratio was higher in reproductive stage indicating that algae tend to accumulate Br compared to F during this stage than at early and senescent stages; though Br level in ambient medium is not a limiting factor. Matrix analysis of DPEF (differential percentage of enrichment factor) of halides shows that the tissue concentration of each halide was independent of other halides accumulation. The extent of bioaccumulation could be related to intrinsic property such as x space (spectroscopic electronegativity) of each halide. The x spec was found to control the relative enrichment of elements (halides). From the available data on Indian marine algae, the stoichiometric relationship of iodine with respect to the bulk constituents was found to be 7900:531:16:1 for C:N:P:I which differs from that of Redfield ratio
