Relationship of qualitative and quantitative fisheries diversity with the environmental
variables was studied for the period of two years along the three zones, viz. upper, middle and
lower, of the Ulhas River estuary. Total ten hydro-sedimentological parameters were analyzed on
monthly basis from each zone to depict ambient pollution level. Zones with comparatively higher
pollution level deterred fisheries landings. The principal coordination analysis (PCO) ordination
and zonewise K-dominance curves revealed the direct correlation of fish diversity with the
existent spatial environmental conditions of the Ulhas River estuary.
