Abstract

Zooplankton is an important biological component of any aquatic ecosystem. Its high rate of production influences enrichment of organic matter and it plays a vital role in secondary and tertiary productions. Zooplankton in the Indian estuaries had been widely studied. Though extensive studies were made on the distribution of zooplankton of estuarine and coastal waters, studies related to mangrove regions were meager. The mangrove ecosystem in the vicinity of Kakinada Bay is a complex environment since this happens to be a transition zone between limnetic and marine regions of the diverse aquatic regimes. Zooplankton form Gaderu and Coringa rivers of the mangrove area of the Kakinada were collected. The results reveal that during the months of November and December coinciding with the post monsoon period peak abundance of zooplankton was noticed. The post monsoons period is the period of re-colonisation. The meroplankton abundance varied between 25.04 % to 32.35 % in the Gaderu River and the similar observation was noticed in the Coringa River also. Since the mangrove habitat provides the natural nutrients through leaching activity, it supports higher percentages of meroplankton.
