Abstract

Paravur Canal is a connecting link between Paravur lake and Edava-Nadayara back water.This paper deals with primary productivity of Paravur canal during the period from January 1999 to June 1999, and their correlation with physico-chemical parameters. Present study revealed that primary production was influenced by pollution, high respiratory rate of secondary producers and nutrients.To assess the effect of pollution on primary productivity from various sources such as factory effluents, domestic waters, husk retting etc., a control site was also selected near bar mouth where lthikkara river joins, is one of the major area for fishing showed high productivity rate.The biological characteristic of Paravur canal was highly influenced by pollution.
