On the Trend of Prawn Catch of Pradeep

Abstract

The distribution and landings of important varieties of prawns off Paradeep coast,
Orissa, in relation to the climatic and hydrographic conditions from 1970-1976 are
presented. The prawn fishery as a whole, showed a quadrennial cycle along the
coast. The post-monsoon migration of all varieties of prawns along the coast
directly depends on the annual precipitation. Temperature gradient, fluctuations
in salinity and southerly wind in the Bay of Bengal influence the migration of the
different species of prawns.
