Description 273-276
Temporal
variations in diatom fouling was investigated at the Dona
Paula Bay
located at the mouth of the Zuari estuary, Goa. Stainless steel panels admeasuring
15×10 cm were exposed to the environment every month for four consecutive days,
over a period of one year (March '96 to February ' 97). Qualitative and
quantitative enumeration of the diatoms from the fouling film as well as that
from the water column was carried out. The surrounding waters were dominated by
the centrales whereas the pennates were abundant in the fouling film. The
pennate diatom Navicula was the most dominant genera both in the water
column and the fouling film . The population of the diatoms in the environment
did not change much during the course of four days of exposure in a given
month, except during the bloom of Skeletonema which was observed in

September. The accumulation
rate of diatom cells with respect to period of exposure was not linear on most
of the occasions. The centric diatom blooms in the ambient waters did not have
significant influence on the diatom composition of the fouling film.
