Abstract
Ornamental fish industry is a booming trade event with species crossing national and international boundaries throughout the year. Rivers are treasure houses of rich Icthyofaunal diversity whose sustainable exploration would boost the ornamental fish industry. The distribution pattern of fish through seasons and places identify the sites and availability of various fish species. In the present work the spatial and temporal distribution of fishes of Keecheri river was studied to aid the process of collections for ornamental fish industry. Species dominance, diversity, richness and evenness were estimated. The fish distribution studies revealed that the river followed a strong longitudinal pattern of distribution. Seasonal distribution of fish indicates that premonsoon and post monsoon season were rich in diversity and richness. Still the appropriate time to collect the fish is during the pre monsoon season when the river start to dry up. High diversity was observed in the downstream.
