Catenella impudica (Mont.) J.Ag is an important species for human consumption from estuarine regions of Asia. Seasonal shedding of carpospores and tetraspores was quantified between January and December 2004 for natural populations of C. impudica. Vegetative and tetrasporophytic plants were available throughout the year but gametophytic plants were observed only from September to May. Tetraspore shedding was observed throughout the year and carpospores shedding was noticed only during the months when material was available. Hydrographical conditions of the estuary such as low water temperature and low salinity are correlated to the formation and release of carpospores and tetraspores in C.impudica

A total of twenty one species of marine macro-algae were reported from 460 kms long Orissa coast in the east coast of India. Of these 9 species belongs to Chlorophyta, 2 to Phaeophyta and 10 to Rhodophyta. The low species richness compared with southern and western coasts of India was due to lack of rocky and/or coral substratum. Enteromorpha usneoides and Gelidium divaricatum were reported first from India. Enteromorpha linza, E. clathrata, Colpomenia sinuosa, Dictyota dichotoma, Catenella impudica, Compsopogon aeruginosus and Grateloupia lithophila were the new records for Orissa coast.
