Indigenous people farmed oysters sustainably for 5000 years

Archaeological study’s findings hold lessons for today’s conservation efforts.

A new archaeological study has unearthed evidence Indigenous people in Australia and North America sustainably managed and consumed oysters for thousands of years.

Oysters are a popular food source for many communities around the world, yet populations of wild oyster species have crashed in regions of both Australia and the United States since European colonisation. It’s estimated that up to 85% of 19th century oyster reef areas have been lost, through a combination of commercial over-exploitation, habitat changes, and the spread of diseases and introduced species.

Now, a large international team of archaeologists and anthropologists has compiled evidence stretching back thousands of years to understand how these resources were managed before European colonisation. The team was led by Torben Rick of the Smithsonian Museum of Natural History and Leslie Reeder-Myers of Temple University, both in the US, and included members of some First Nations groups from the areas studied.

“Oyster harvesting didn’t start 500 years ago with the arrival of Europeans,” explains study co-author Bonnie Newsom, an anthropologist at the University of Maine, US, and citizen of the Penobscot Indian Nation. “Indigenous peoples had a relationship with and understood this species well enough to use it as part of their subsistence and cultural practices.”

1. Wacko article. "Sustainably" "avoided overharvesting"

With small migrant populations back then, such issues would not arise and would not be contemplated. That article puts a modern take on an ancient problem but seems unaware.

2. True but ... the concept of sustainable is independent of intent

The article doesn't say purposefully sustainable

All they really know is that there's not evidence of over-harvesting. Could be many reasons for that, including it being intentional.
