estuary was investigated during premonsoon 2011. Important hydro-biological
parameters such as water temperature, salinity, pH, DO, NO2, NO3,
NH4, PO4, SiO4, TSM, Chl-a, phytoplankton
and zooplankton were measured during the present study. Temperature established
a strong positive correlation with salinity and pH during the present study.
Chl-a found in positive relation with NO3, SiO4
and TSM. Analysis of variance revealed significant monthly variation in pH,
salinity and TSM. Significant station wise variation was observed in DO and
most of the nutrients i.e., NO3, NH4, PO4,
SiO4. A total of 119 species of phytoplankton were identified of
which 84 species are of diatoms, 22 species of dinoflagellates, 7 species of
green algae, 5 species of cyanobacteria (blue green algae) and 1 species of
cocolithophore. Phytoplankton abundance varied between 25543 (Nos. L-1)
and 36309 (Nos. L-1). Diatoms dominated the phytoplankton community
followed by dinoflagellates in all the months. Diatoms contributed to 82-89%
of the total phytoplankton population density whereas dinoflagellates contributed
to 6-12%. The regression between Chl-a and phytoplankton abundance resulted
with weak relation (R2 = 0.042). Zooplankton fauna composed of 134
species of holoplankton and 20 types of meroplankton were encountered during
the study period. Zooplankton population dominated by copepod during all months
and accounted for 74 to 85% to the total zooplankton. The population density
ranged from 6959 to 35869 Nos./10 m3. Analysis of variance explained
no significant variation in total zooplankton abundance and also for different
groups of zooplankton.]]>Achary, M.S., G. Sahu, A.K. Mohanty, M.K. Samatara and S.N. Panigrahy et al.,20102553568Bethoux, J.P., P. Morin and D.P.
