| Abstract: | Diversity of phytoplankton and water quality
of Dahanu creek was studied during November 2008 and October 2009. Physicochemical
parameters indicated variations in depth, pH, temperature. DO, BOD, salinity,
nitrite, nitrate, ammonium nitrate, phosphate etc. Total 52 genera of
phytoplankton were observed during the study period comprising diatoms,
dinoflagellates and other algae. Coscinodicuss,
Rhizosolenia, Biddulphia, Melosera, Bacillaria, Isthmia, and Gyrosigma were
dominated among the phytoplankton community. Diversity index of phytoplankton
ranged from 2.61 to 6.37. Dahanu creek maintained fairly high concentration of
chlorophyll a, ranging between 0.96 to 7.65 (average 3.30). Maximum value of
chlorophyll a was recorded at stn.1 from the bottom water during June 2009
which coincided with the highest cell count of phytoplankton total 758
phytoplankton recorded for that station. This was also associated the boom of
coscinodicuss.There was gradual increases in chlorophyll a from creek area. Distribution
of phaeophytin ranged from 0.65 to 4.49 (average 1.94) and it was comparable
with chlorophyll a. However Station 1-3 maintained higher value of chlorophyll
a than the phaeophytin while the area of station 4-5 showed low concentration
of chlorophyll a and phaeophytin. Dahanu creek consists of rich and divers
phytoplankton community. |
