| 1 | Relationship between plankton and finfish and shellfish juveniles in Pichavaram mangrove waterways, south east coast of India Qualitative and quantitative assessments of phytoplankton in Pichavaram mangrove, Tamil Nadu, India waterways were made monthly for a period of two years (1980-82) in order to investigate the relationship between phytoplankton abundance and that of the juveniles of commercially important finfish and shrimps. Totally 84 species of phytoplankton comprising 74 species of diatoms, 5 species of dinoflagellates, 4 species of blue green algae and 1 species of green alga were recorded. The density of phytoplankton ranged from 12 to 40,11,872 cells/1 during the period with peaks during summer and post-monsoon seasons. The positive relationship observed between the phytoplankton and the finfish and shrimp juveniles, indicates that phytoplankton could be one of the major factors influencing the temporal fluctuations of the populations of fish juveniles in this mangrove biotope.

| 2 | Seasonal variation of phytoplankton in Uran estuary The standing crop of phytoplankton, interms of biomass, and total cells, recorded high values during the rise as well as maturity of the mud bank. Qualitatively, a total of 37 species of phytoplankters were present. A notable feature seen in association with the mud bank was the blooming of @iNoctiluca miliaris@@. The present investigation was worked out in Uran estuary (Lat. 20 degrees 29 minutes N & Lon. 77 degrees 32 minutes E) during March 1997 to February 1998. The possible relationship of phytoplankton to and the role it plays at the mud bank is briefly discussed. Source: Babu, K.N.; Yeragi, S.G.; Yeragi, S.S.
