Abstract

Ninety two species of commercially important finfishes (12 marine, 63 estuarine cum marine, 9 estuarine and 8 freshwater) were recorded in Vellar Estuary. Diversity indices as Shannon diversity, Margalef richness index and phylogenetic diversity were high. The gradual (serial) change in species diversity from the mouth to upstream and seasonal variations (cyclic) studied using RELATE were statistically significant. The factors responsible for serial changes in diversity were observed to be salinity and strength of monsoon (indirectly salinity).
