Oyster management strategies often rely on knowledge and data from the past two centuries \u2014 a period during which many oyster fisheries collapsed due to overharvest, habitat loss, and other causes.&nbsp;<\/p>\n\n\n\n<p>In contrast, archeological records indicate that Indigenous fisheries thrived for millennia. Understanding the historical practices of Indigenous oyster fisheries is crucial for sustainable management of modern oyster populations. Additionally, incorporating Indigenous knowledge not only promotes ecosystem health, but helps to restore the rights of Indigenous communities.<\/p>\n\n\n\n<p><strong><em>What did they study?<\/em><\/strong><\/p>\n\n\n\n<p>Researchers collected archaeological data from their own work and a number of other sources, spanning 7,000 years of oyster data. They studied over 200 Indigenous oyster fishery sites in North America and Australia, including about 50 sites along the southern Atlantic coast from South Carolina to Florida. The team analyzed shell mounds and other archaeological debris to gain insights into the scale, longevity, and management of these fisheries.\u00a0<\/p>\n\n\n\n<p>The team also examined published and unpublished literature to learn more about the historical importance and practices around oysters in Indigenous communities.<\/p>\n\n\n\n<p><strong><em>What did they find?<\/em><\/strong><\/p>\n\n\n\n<p>Indigenous peoples sustained massive oyster fisheries for 5,000 to 10,000 years \u2014 or more. In the southern Atlantic region, oyster sites were especially numerous between 2500 and 1500 BCE.&nbsp;<\/p>\n\n\n\n<p>Unlike modern-day commercial harvests, Indigenous management often maintained abundance, which was later exploited by settler colonial enterprises. However, some Indigenous fisheries shared commonalities with today\u2019s commercial fisheries, like selling surplus oysters and accumulating wealth. The displacement of Indigenous societies often preceded the collapse of fisheries, with far-reaching impacts on ecosystems and the resilience of oyster populations.<\/p>\n\n\n\n<p>Indigenous harvesting practices ranged from small seasonal camps to large villages, with some sites yielding tens of millions or even billions of oysters. The <em>largest site<\/em> in the study was in the peninsular Gulf Coast (Mound Key, Florida) with over 18 billion shells. The largest East Coast site was in South Carolina (Fig Island), with over 75 million shells.<\/p>\n\n\n\n<p>These findings highlight the significant, controlled role Indigenous communities played in oyster harvesting \u2014 which other studies have underestimated, characterizing Indigenous fisheries as \u201clightly fished\u201d or \u201cwild.\u201d<\/p>\n\n\n\n<p><strong><em>Anything else?<\/em><\/strong><\/p>\n\n\n\n<p>Large mounds and other structures made mostly from shells show that oysters and other shellfish were important in the social, political, and religious activities of Indigenous peoples. For instance, massive shell mounds found in various regions served as platforms for rituals and ceremonies.<\/p>\n\n\n\n<p>Despite colonization and displacement, Indigenous communities have preserved their traditional ecological knowledge related to oyster harvest and management, for example in practices like oyster farming and artificial reef construction.<\/p>\n\n\n\n<p><strong><em>So what?<\/em><\/strong><\/p>\n\n\n\n<p>The state of oyster fisheries today reflects more than just environmental changes \u2014 it\u2019s about the loss of complex socio-ecological systems. While oysters are well-studied globally, archaeological data on Indigenous fisheries have been overlooked. Research suggests Indigenous oyster fisheries were sustainable because they were part of larger interconnected systems, not separate economic activities.&nbsp;<\/p>\n\n\n\n<p>Working with Indigenous groups to restore their relationships with oysters and their traditional lands offers a path to healthier fisheries and environments. This collaboration could involve sharing knowledge, conducting research together, or restoring control over land management to Indigenous communities.&nbsp;<\/p>\n\n\n\n<p>Finally, the authors \u2014 several whom are members of Indigenous communities from the studied territories \u2014 note the data for their study come from the colonized lands of dozens of Indigenous nations and that archaeological research and heritage management should involve consultation and collaboration with Indigenous communities.<\/p>\n\n\n\n<p><strong><em>Reading<\/em><\/strong><\/p>\n\n\n\n<p>Reeder-Myers, L., Braje, T.
