Production of organic matter by phytoplankton is of utmost importance because it initiates the whole marine food chain, which terminates in the larger fishes and sea mammals. The fundamental process in the production of organic matter can be given by the following eqauation: 6 CO2+ 6 H2O C6H12O6+ 6 O2 The prime synthesisers are the plankton algae found in the upper layers of the sea where there is sufficient light for photosynthesis. Therefore a measure of the standing crop and rate of production of plant material is of greatest importance in fisheries research just as livestock raisers need a knowledge of the pasture conditions. The word production has been used synonymously with standing crop. But there is a sharp distinction between the two, although in nature there is rather a high correlation between the standing crop of phytoplankton and primary production. Eventhough considerable amount of information was available on the standing crop measurements at different regions of the India seas, no data were available on the production of organic matter until the Danish Galathea Expedition laid the foundation by the introduction of radio-active carbon (C14 ) in the study of primary production and made measurements in the equatorial part of the Indian Ocean and in the Bay of Bengal (Steemann Nielson, 1952: Steemann Nielsen and Jensen, 1957).
