Description 62-65
A. coffeaeformis, one of the dominant diatoms occuring throughout 2-year period of investigation in the Adyar estuary is usually abundant in waters of intermediate salinities. Laboratory studies on several isolates of A. coffeaeformis from this estuary confirm this behaviour. The diatom does not grow very well in fresh water (Reimann medium with no chlorides) but prefers a medium with low chloride (NaCl) levels. When the chloride content is too high growth of the diatom declines. According to the classification of euryhaline diatoms proposed by Desikachary and Rao (J. Mar. Biol. Assoc. India, 14; 1972; 524) A. coffeaeformis is meso-euryvalent in its behaviour though it occurs in a wide range of salinity conditions.
