Title Preliminary account of primary production and its relation to fisheries of the inshore waters of the Gulf of Mannar
 
Creator Raghu Prasad, R
Nair, P V Ramachandran
 
Subject Primary Production
 
Description In the ecological studies of marine environments dynamics of production
and the quantitative aspects of the relations involved have received special
interest. Such quantitative studies of the various relationships have resulted
in the familiar 'Eltonian Pyramid' which represents the layering of the
community brought about by the feeding habits of different species. But
due to the inevitable loss of materials at each level in the food chain the
yield normally will be smaller than the supply. According to Clarke (1946)
"the measurement of the ratio of yield to supply, and hence the efficiency
of the formation of the yield, is therefore of great importance to the ecologist,
to the conservationist, and to the farmer or fishermen, in order to ascertain
whether the actual yield represents a needlessly low utilization or an overexploitation
of the area.
