Gharials are critically endangered crocodilians found only in the river systems of the Indian subcontinent. Their welfare is threatened by fishing gear entanglement, habitat degradation, and sand mining.
Gharial welfare harms arise primarily from their specialized habitat requirements and vulnerability to incidental fishing mortality. Net entanglement causes drowning in animals that must surface frequently to breathe. Nesting beach destruction from sand mining eliminates the specific microhabitat females require for egg laying. Hatchlings entering rivers with low fish populations face nutritional stress. The narrow habitat range of gharials — specialized river systems with specific geomorphology and prey density — makes their welfare inherently tied to river ecosystem health. Conservation interventions that protect nesting beaches and reduce incidental fishing mortality directly improve individual animal welfare alongside population outcomes.
