As the name tag says this blog will serve as an introduction to Acipenser fulvescens, the mighty Lake Sturgeon. We, the sturgeon and I, are just now becoming acquainted. For my master’s I worked on a tiny minnow called the Clinch Dace, which when full grown, measures a maximum of 8-9 cm and weigh less than 10 g. I will now be working on a fish that can reach lengths surpassing 7 feet and weights up to 110 kg. To put that in perspective, the weight of largest Lake Sturgeon ever caught may surpass the combined weight of all of the adult Clinch Dace on the planet (Moore 2016). I’ve got a lot to learn…
It’s okay though. I’ll have 4-5 years to study the Lake Sturgeon. I’ll be implanting acoustic telemetry tags in these guys and gals and following them on their seasonal migrations around Central Missouri’s rivers.
Perhaps it is best to start our introduction of the Lake Sturgeon with a post about some of man’s first interactions with this species. Native Americans knew sturgeon well and tribes of the upper Midwest such as the Ojibwe had a deep respect for this fish. Before affluent modern society decided that Sturgeon caviar should become the culinary equivalent of gold (treatment of white American’s early relationship with the sturgeon will require its own post), Native Americans had long celebrated the return of Sturgeon at rapids in the spring during their annual spawning run. The arrival of the Lake Sturgeon, or “name” (nah-may) as they called them, were celebrated with festivals, feasts, and rituals. The Menominee considered the Sturgeon one of their founding ancestors but after a long harsh Wisconsin winter where food was scarce, they didn’t mind inviting their big, easily captured relatives over for dinner. At these sturgeon feasts, the fish were eaten but also offered to the Gods with thankful praise. These tribes even began the practice of spearing sturgeon through the ice which continues to be a popular regional sportfishing practice today.
In recent years, tribes like the Menominee have been instrumental in restoring Lake Sturgeon to their native habitats where past harvest and dams had thwarted their migrations. Just as the name had helped give birth to their tribes, they are giving this fossil of a fish a second chance at life in Wisconsin’s lakes and streams.
