Abstract:
Prawn culture by traditional method forms an important occupation for the people in these areas, especially in the Vypeen island. Though short term studies have been made on various aspects of prawn culture field and its ecology, a study of detailed nature covering perennial, seasonal, fields and canals between coconut plantation is lacking from these areas. This study will also enable to assess the relative productivity of different systems during different seasons and the influence of the environment on the production potentials. Therefore the present study is taken upto throw more light on the ecological characteristics of these fields with special emphasis on its primary, secondary and tertiary production. The present area of investigation includes the prawn culture fields adjacent to Cochin backwater. The Cochin backwater (O9° 58'N 76° 28'E) is a shallow semi-enclosed body of water of tropical estuary. A narrow gut, about 450 M wide forms its main connection with the Arabian sea and this region is subjected to regular tidal influenceertiary production.

Abstract:
Ecology is the study of systems at a level
in which individuals or whole organisms may be
considered elements of interaction, either among
themselves, or with a loosely organised environmental
matrix. Systems at this level are named
ecosystems, and ecology, of course, is the biology
of ecosystems" (Hargalef, 1968).
This thesis includes principally, a study on
the ecology of zooplankton of the Cochin backwaters
conducted during the years 1971-72. This monsoonal
estuarine system is particularly interesting, since
it exhibits a wide range of variations in its environmental
conditions which is naturally reflected in
the fauna also. Several publications on various
aspects of its hydrobiology have come out in the
recent past. But studies on the zooplankton of the
estuary have mostly been discontinuous either in space
or time or restricted to its groups
