Abstract

Essential micro-nutrients such as manganese, copper, lead and zinc were analysed
in three species of Gracilaria for 12 months from August 1994 to July, 1995.
Comparative data on the interspecific variation of essential micro-nutrients have
been explained. Seasonal variation of the trace element within the species were
also analysed. Zinc content was found to be maximum in all the species of
Gracilaria. In general, the decreasing trend of essential micro-nutrients was
Zn>Pb>Cu>Mn. Manganese and copper content were found to be comparatively
higher in G. edulis whereas lead dominated in G. crassa
