The coalescence of freshwater and marine ecosystems during flood events introduces a distinctive ecological phenomenon wherein freshwater fish become entrapped in saline waters, an occurrence commonly referred to as “fish strangulation’’. This article presents a focused exploration of this phenomenon, in the Karaikal region in Tamil Nadu, India as a case study. This research aims to uncover the causes, assess the ecological impacts and delineate adaptive strategies employed by fish populations amidst the unprecedented convergence. The coastal region of Karaikal in Tamil Nadu, India, has long been characterized by its susceptibility to extreme weather events, particularly flooding resulting from monsoons and cyclonic activities. In recent years, a peculiar ecological phenomenon has emerged, drawing attention to the interactions between freshwater and marine ecosystems during flood events. This phenomenon involves the strangulation of freshwater fish within the saline waters of the sea, presenting a unique and poorly understood ecological challenge.
