Gharials are among the most critically endangered crocodilians, restricted to a few rivers in northern India and Nepal. Their specialist needs make welfare in captivity challenging but conservation-important.
Gharial welfare in captivity depends on replicating the deep river conditions in which they evolved. Shallow enclosures prevent the diving and aquatic locomotion central to their behavioural repertoire. Temperature management is critical — gharials basking inadequately develop metabolic bone disease and immune compromise. Their specialist fish diet must be provided in forms allowing natural snapping behaviour. Given their critically endangered status, captive welfare must be taken seriously — stressed, unhealthy captive animals do not contribute effectively to breeding programmes. Only institutions with appropriate deep-water facilities, correct temperature management, and species-appropriate nutrition should hold this species.
