Description 673-684
Present
study consists the relationship between phytoplankton community structure and
physico-chemical parameters in Mahim Bay and Manori Creek. Altogether, 230 phytoplankton
taxa comprising 131 diatoms, 82 dinoflagellates and 17 marine flagellates were
recorded. Centric diatoms were the most common taxa, followed by thecatedinoflagellates.
Seasonal blooms of diatoms and dinoflagellates occurred in the summer and at the
end of the south-west monsoon. Additionally, we here report the first finding
of two harmful dinoflagellate species, i.e. Pyrodinium
bahamense and Dinophysis norvegica,
in Indian coastal water. Dinophysis cf.norvegica was observed sporadically at Manori Creek. Except for PO43-,
levels of major nutrients were low at both sites. Canonical correspondence
analysis indicated that the relative abundance of some species was influenced
by heavy metals and salinity. Dinophysis,
Protoperidinium, Ceratium and Leptocylindrus were
inversely correlated to salinity, whereas some of the marine flagellates (e.g.,
Chrysochromulia, Heterocapsa, Heterosigma and
Fibrocapsa) and dinoflagellates
(e.g., Noctiluca and Amphidinium) were seen alongside higher
levels of heavy metals, such as Fe, Ni, Cu and Cd.
