Freshwater fish are among the most threatened vertebrate groups globally.
Gharials feed almost exclusively on fish, making prey diversity and abundance critical for survival. Rivers with high fish species richness support more stable gharial populations. Overfishing, pollution, and invasive species reduce prey availability and nutritional balance. Specialized dentition limits dietary flexibility. Population surveys often correlate declining fish stocks with reduced juvenile growth rates. This tight ecological coupling creates vulnerability. Predator fate mirrors prey health with little buffer.

Unlike generalist predators, gharials cannot pivot to alternative food sources easily. A decline in even medium-sized fish can alter energy intake significantly. Reduced prey diversity also increases reliance on fewer species, amplifying risk if those species decline further. The predator-prey relationship is tightly calibrated.
Fish conservation becomes synonymous with gharial conservation. Sustainable fisheries management directly influences predator recovery. Protecting spawning grounds and water quality benefits entire trophic structures. In this ecosystem, the apex predator is only as resilient as the fish beneath it.
