Sea Otter Reintroductions: A Complex Social, Ecological and Cultural Endeavor
This article was originally published on the Cross-Pacific Indigenous Aquaculture Collaborative Network (IACN). This organization is a collaboration between Pacific-region Sea Grant offices, Northwest Tribes and First Nations, Native Hawaiian and Indigenous communities, organizations, and universities. The mission of this network is to advance Indigenous Aquaculture through the integration of communities, restoration, applied research, and education in an effort to bring together knowledge that ensures local and cultural seafood production in the Pacific. Olivia Horwedel is the communications fellow for the IACN and was invited to publish a blog about her capstone research. Isabel Jamerson, Daniel Kosiba, and Olivia Horwedel are all working together for their capstone, and wrote this article together for its original publication on the IACN blog.

A coastline splashes with a flurry of sea otters weaving in and out of waves, darting around each other, and plucking away at prey. When looking across a lively seascape like this, dense in tangled rafts of otters and kelp forests alike, it is hard to imagine them missing from the picture.
But, when the fur trade took off in the 19th century, coastlines along the Pacific quieted as sea otters were extirpated.
Little did people know then, but sea otters help balance these ecosystems with their voracious appetites. Soon after their near-extinction, the otters’ prey species, now unchecked, boomed. Sea urchins quickly ate their fill of kelp, nearly decimating this essential underwater habitat. Many species dependent on kelp lost their homes and sources of food.

Humans are just as much a part of this ecosystem as any other species, with their own dynamic relationships with sea otters, shellfish, and the ocean. These relationships are especially maintained by the Indigenous Peoples who have lived along the Pacific Coast since time immemorial. The Coastal Voices Project — a collaboration led by two of the Cross-Pacific Indigenous Aquaculture steering committee members, Anne Salomon and Kii’iljuus Barbara Wilson — describes some of the complex relations that Indigenous communities have with otters. Examples of these relationships include utilizing their furs for ceremony and survival or selectively hunting them to steward a balanced ecosystem.
Over the last 80 years, people have sought to restore sea otters throughout the West Coast, from Alaska all the way to California. By translocating a few otters from healthy populations in Alaska to areas where they once lived, people have restored otters to many locations. While there was an early period of uncertainty as ecosystems rebalanced, populations of otters now thrive in many places along the West Coast of North America.

Sea Otters and Aquaculture
While successful reintroductions of otters are considered large-scale ecological wins, the social and cultural dimensions of the reintroductions have not been appreciated, and as a result, not prioritized. Sea otter reintroductions have largely been orchestrated by government agencies, rather than co-developed with Tribal Nations, consequently threatening many commercial fisheries, traditional aquaculture practices, as well as shellfish harvests of Native American and First Nations communities.
In Alaska, sea otter populations flourished upon reintroduction. In the initial stages, otters in Alaska devoured populations of abalone, crabs, and other culturally and commercially important species. Sea otters can consume over 25% of their body weight every day to fuel their metabolism and keep their bodies warm. Their insatiable appetite for shellfish has hurt subsistence and traditional harvesters as well as commercial fishers.
Over time, Alaskan ecosystems have become more balanced as selective hunting of otters and collaborative management among Alaska Native communities and the government was implemented. Under an exemption of the Marine Mammal Protection Act, Alaska Natives are able to continue their right to traditionally and selectively harvest otters. With this exemption, communities can better control otter and shellfish populations while also reestablishing a cultural connection to otters through the revitalization of tanneries and the use of otter pelts for handicrafts. More recently, some local residents to Southeast Alaska have noted that the sustainable harvest of reintroduced otters has resulted in rebounded populations of shellfish such as abalone, chitons, urchins and sea cucumbers, rebalancing the ecosystem at large.
In British Columbia, experiences with sea otter reintroductions are quite complex and differ from what was experienced in Alaska. During their doctoral research at the University of British Columbia, Jordan Levine and colleagues found that the opinions on sea otter reintroductions varied within First Nations communities on the British Columbia coastline. When speaking with men and women in coastal communities, their research found that women felt the greatest losses from sea otter reintroductions due to their role as the primary shellfish harvesters. While some First Nations men harvest shellfish, their primary role is fishing, where the impacts of sea otters have been known to benefit certain commercially valuable fish populations, increasing the total catch for fishers interviewed.

There are multiple perspectives that Indigenous communities hold when it comes to the reintroduction of sea otters. Most sea otter reintroductions that have occurred thus far have been done without gathering Indigenous perspectives or involvement of Native American and First Nations communities in co-management. Inclusion of Indigenous communities that rely on shellfish harvesting for cultural, economic, and food security in future sea otter management would help to ensure greater equity in outcomes, and support reconciliation through improved access to decision-making processes.
A Collaborative Approach to Restoring Sea Otters
The three of us — Olivia, Isabel, and Danny — entered into our master’s program at the University of Washington’s School of Marine and Environmental Affairs with the goal of engaging in work that supports Indigenous resurgence and sovereignty. We hoped to better understand research methodologies that foster relationship building and expand beyond dominant, Western scientific approaches to environmental management. With these goals in mind, we began a collaborative capstone partnership with the Elakha Alliance in early 2022, working to restore otters to the Oregon coast.

Elakha is the Chinook trading language word for sea otter and represents a long history Indigenous Peoples have held with sea otters in what is now Oregon. Sea otters were hunted for their fur along the western Pacific coastline during the maritime fur trade, and by the early 1900’s they were considered locally extinct in Oregon. Formed in 2018 by Tribal, nonprofit, and conservation leaders, the Elakha Alliance hopes to restore the ecological and cultural connections among otters and coastal communities. The Alliance seeks to evaluate how the reintroductions of sea otters to Oregon’s coastal ecosystems have the ability to restore and revitalize a culturally important species.
Tribal leadership on the Elakha Alliance’s board helps to ensure that Indigenous perspectives are central to the effort to return sea otters to Oregon. As a member of both the Elakha Board and the Confederated Tribe of Siletz Indians, Peter Hatch expresses their ancestral kinship relationship with sea otters and ocean abundance:
“Since the beginning of time, when our newly-created peoples’ footprints first marked the sands, we coexisted with Elakha. The stories of our Ancestors instruct us to recognize sea otters as one of our respected kin, our cousins as it were, and that preserving that kinship- and all our relationships to the natural world- would help us forever enjoy the bounty and abundance that the ocean has to offer for our sustenance and our prosperity.”
In our capstone work, we are interviewing Tribal members, government officials, and scientists along the Pacific coast in hopes of providing useful frameworks that highlight opportunities for Indigenous sovereignty and co-management in sea otter reintroductions with government agencies like Oregon Department of Fish and Wildlife and US Fish and Wildlife. We hope this work informs ongoing collaborations that support community-driven reintroduction efforts that prioritize Indigenous community needs and center Indigenous food sovereignty and resurgence.
