Primary Production
 
Description 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).
