Description 365-371
Present study provides
information about the cyst assemblages as an indication of eutrophication in
the harbour.
Two sediment core samples were collected from the Eastern Harbour during 2008.
Fifteen genera with 26 species were identified from the two cores with total
cyst abundance ranging from 138 to 1296 cysts [g-1] [s2] dry wt. Protoperidinium
spp. cysts contributed a maximum of 43% to the total cysts, followed by Alexandrium
spp. 21% and Diplopsalis cysts with
13%. During this study, six cyst genera with thirteen heterotrophic
dinoflagellate species were identified with cyst concentration ranging from 12
to 820 cyst [g-1] [s3] dry wt. Total heterotrophic cyst showed a significant
positive correlation with diatoms, sedimentary TP and TN, indicating that
increase in diatoms and nutrient concentrations are the main cause of
heterotrophic dinoflagellate.
