ESTIMATION OF INCIDENT SHIFT OF RIVER FISH SPECIES COMMUNITY FROM LONG TERM SHIFTS OF WATER RESOURCES USES IN GLOBAL SCALE

Abstract

Freshwater creatures are affected by mankind's impact such as irrigation and water pollution more than by land and marine creature and this leads to ecosystem deterioration in the river. The purpose of this study is to evaluate the these change every global river using future estimated river discharge and decide dangerous area for the survive of fish species. The results showed that the area which will be dangerous in the future were North America, South America, Africa, Oceania, South Asia and East Asia. The present study suggests that deterioration of river ecosystem will happen in many areas of the world in the future.
