A fish swimming in the Great Lakes today may have been alive before many colonial settlements existed in the region.

A new scientific study suggests lake sturgeon may live far longer than previously believed. Using 44 years of tagging and recapture data from five Great Lakes populations, researchers estimated that male lake sturgeon may live 90 to 279 years, while females could potentially reach 99 to 427 years.

For many years, scientists estimated sturgeon age by counting growth rings in fin spines, similar to tree rings. Researchers now say that method becomes less reliable as lake sturgeon age because their growth slows and the rings become increasingly difficult to distinguish. By tracking individual fish over decades, the study offers a new way to understand how long these ancient fish may live.

The findings also align with knowledge long shared by some Indigenous communities, whose oral traditions have described lake sturgeon as exceptionally long-lived beings. In many Great Lakes cultures, sturgeon hold deep importance as part of foodways, seasonal knowledge, and relationships with waterways.

Lake sturgeon were once heavily harvested and treated as nuisance fish in the late 1800s, contributing to major population declines. According to Michigan DNR reporting, less than 1% of historic Great Lakes lake sturgeon numbers remain. Because they mature slowly and reproduce over many decades, recovery takes time across generations.

The study highlights the value of long-term monitoring and collaboration among Tribal Nations, fisheries researchers, universities, and conservation agencies. Protecting healthy rivers, spawning habitat, and connected waterways remains important for the future of this species.

If something has a big fandom, publishers and studios know they can make money off it. This is why we see publishers openly acquiring and selling things that were originally posted as fanfic, like Alchemised, Heated Rivalry, etc. It’s why the horrid wizard woman considers people participating in her fandom to be supporting her political causes.
