sector, where several industrial activities occur
(Fig.

). The intense industrial activities in the
western part of the Indian Sundarbans release
large amount of colloidal particles, oil and sev-
eral waste materials of complex collector. This
causes low penetration of solar radiation due to
which the biomass of
The growth of seaweeds in the marine, estuarine
or coastal waters depends on two important
parameters. These are salinity of the surrounding
and presence of light to drive the process of
photosynthesis. Seaweed grows better where the
suspended particulate matter (SPM) is low. In the
lower Gangetic region, the growth of seaweed
has been found to be more in the eastern sector of
Enteromorpha intestinalis,
Ulva lactuca and Catenella repens
is relatively
low compared to the eastern sector (Fig.
