Please join the Great Lakes Center for the seminar "Listening In on Lake Sturgeon in the Buffalo Harbor," presented by Jonah Withers of the U.S. Fish and Wildlife Service, on Tuesday, March 29, from 3:00 to 4:00 p.m. in Science Building 272. All students, staff, and faculty are welcome.

Seminar Abstract
Lake sturgeon Acipencer fulvescens, one of the largest and longest-living freshwater species endemic to North America, were considered a nuisance bycatch in the early and mid-1800s. In the late 1800s, lake sturgeon became targeted for their prized meat and roe once markets became established, which, in combination with a suite of other factors, led to a precipitous decline in populations in the late 1800s and early 1900s. Recovery efforts are under way, and lake sturgeon are now allegedly resurging throughout their native range from natural recruitment and rehabilitative stocking. Little is known about the status of a remnant population of lake sturgeon in the Buffalo Harbor and upper Niagara River. We are exploring the use of acoustic telemetry to fill information gaps about the range and life history of this ancient keystone species.
