Abstract

An attempt was made to study the optimum concentration of culture media required for the culture of Chaetoceros calcitrans under laoratory conditions so as to achieve a viable and economical method of culture. The aim of the study was determination of the effectiveness of hydrological factors especially nutrients which was supplied externally to the seawater while culturing the diatom, and to determine its optimum concentration for ideal growth of the culture. The cell count, percentage of transmittance and the chlorophyll a values are significantly higher for the group in which the medium was provided on the initial day. Almost similar values were also noted for the 5th day’s enrichment, indicating that the culture can grow upon the nutrients present in the seawater up to the 5th day and enrichment is needed only afterwards.
