Abstract: | Dugongs (Dugong dugon) are a key food item and a totemic animal with major spiritual significance for Torres Strait Islanders of northeastern Australia. These marine mammals are officially classed vulnerable to extinction which has placed hunters under considerable internal (cultural) and external (bureaucratic) pressure to lower hunting rates dramatically to sustainable levels. But did Torres Strait Islanders hunt dugongs at much lower rates in the pre-colonial past? Excavation of a ritual dugong bone mound on Mabuyag island revealed the remains of 10,000–11,000 dugongs hunted between c. 1600 and c. 1900AD. The translated hunting rate of 33–37 dugongs per year is surprisingly high and challenging as this single site represents one-third of what conservation biologists argue is the current mean sustainable hunting rate for the entire Torres Strait archipelago. These data suggest that dugong abundance was much higher in the pre-colonial past and that current hunting rates are uncharacteristically unsustainable primarily due to an unprecedented dugong population crash and not increased post-contact hunting rates. |
