Dugong Conservation and Welfare in the Indo-Pacific

Dugongs (Dugong dugon) are the only fully herbivorous marine mammals and are vulnerable to extinction across their Indo-Pacific range. Their welfare is threatened by multiple human activities.

Key Facts

Dugongs are classified as Vulnerable globally but Critically Endangered in some regions including the Red Sea and East Africa
They are the only surviving member of the family Dugongidae — their closest relative, Steller's sea cow, was hunted to extinction in 1768
Dugongs graze exclusively on seagrass — they require vast, undisturbed seagrass meadows to survive
They reproduce very slowly — females first breed at 10 years and give birth every 3-7 years
Boat strike injuries are a major welfare and mortality concern in areas with high vessel traffic
Accidental capture in shark nets and gill nets causes drowning deaths
Seagrass loss from coastal development, runoff, and climate change threatens food security for remaining populations

Welfare Considerations

Dugong welfare is inseparable from seagrass ecosystem health. Dugongs that cannot access adequate seagrass face nutritional stress — they must travel greater distances to find food, expending energy while consuming less. Boat strikes cause traumatic injuries ranging from propeller lacerations to blunt force trauma — many dugongs carry healed propeller scars indicating survival of at least one collision. Net entanglement causes drowning; dugongs must breathe every 1-3 minutes and cannot survive extended entanglement. In some cultures, dugong hunting continues legally or illegally; spear hunting causes prolonged suffering and death. Establishing marine protected areas with boat speed restrictions and net-exclusion zones in critical dugong habitat provides the most effective welfare and conservation protection.

What You Can Do

Support WWF and Sea Shepherd programs protecting dugong habitat from destructive fishing and development
Observe boat speed restrictions in dugong habitat areas and report violations to local marine authorities
Donate to coastal seagrass restoration programs that maintain dugong food resources
Advocate for marine protected areas with exclusion zones for destructive fishing in dugong range
