Abstract:
Enhancement and culture of bivalves presents an opportunity
to maximise and even increase production of many growing areas. Clam
culture is less intensive both for capital and labour, involves simple farming
and management techniques and is considered an efficient means of protein
production. Clams are efficient converters of primary production and
growth rate is fast with maximum production in 5-6 months. with culture,
production is less influenced by poor recruitment. Stable production
facilitates market development. Rivalves are being increasingly used
in bio-medical research. Culture practices would ensure uninterrupted
supplies of experimental material. Paucity of biological data restricts the development of efficient management and culture techniques of bivalves. This study was undertaken with a view to provide information on some aspects of biology of the bivalve S_. scripta which have hitherto been uninvestigated.

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
