Exhibit celebrates black gold, aka sturgeon

Body: 

A fish of legends, caviar and intensive management, lake sturgeon (Acipenser fulvescens) have been on Earth for over 100 million years. They are the subject of an art exhibit, "Black Gold," at the Prøve Gallery, 21 N. Lake Ave.

There will be a reception, zine release and panel discussion on Friday, April 7. Doors open at 6 p.m. and the panel begins at 7 p.m. This event is free and open to the public. The exhibit of black-and-white images of sturgeon by multiple artists runs through April 8.

Lake Sturgeon can grow to 8 feet long and weigh more than 300 pounds. They are one of the longest living fish; a female tagged in Wisconsin was likely 125 years old.

They have a harmless disposition and a toothless grin. Belying their size, they suck their diet of relatively small organisms, including mayfly nymphs, other aquatic insects, and crayfish from the bottom of lakes and rivers.

By the early 1900s, they were becoming scarce. People dined on sturgeon meat, used their skin for leather and made their swim bladders into isinglass (an aspic for pottery cement, waterproofing, and clarifying wine and beer).

Additionally, people, cities, and industries altered water with pollution, dams, and activities that further diminished lake sturgeon populations. In the wake of these multiple stressors, lake sturgeon all but vanished. Today, thanks to the Clean Water Act and rigorous reintroduction projects involving habitat restoration and stocking, lake sturgeon are faring better.

The exhibit was organized by Associate Professor Ryuta Nakajima and Assistant Professor Darren Houser from UMD's Department of Art and Design. Don Schreiner, Minnesota Sea Grant (MNSG) fisheries extension educator, and Sharon Moen, MNSG science writer, contributed to the program.

Nakajima and Houser will serve as facilitators of the panel discussion. Also on the panel will be Nevada Littlewolf, city councilor/leader of Rural and American Indigenous Leadership, Tedy Ozersky, limnologist, UMD Large Lakes Observatory, Paula Polasky, lawyer and founder of MiNNBOX, and Jay Walker, director of operation, Great Lakes Aquarium. The event is supported by Prøve Gallery, Minnesota Sea Grant, UMD Viz Lab, and the Great Lakes Aquarium.

The art will be compiled into a limited-release publication, or zine. Artists include Cassie Marie Edwards, Adam Rosenthal, Adrian Chin, Andy Ducett, Ashley Nason, Catherine Meier, Chris Hutson, Christopher Atkins, Eiketsu Baba, Kyle Bernier, Keith Larson and Laura Hallen.

The exhibit opened March 24 and runs through April 8. It will move to the Great Lakes Aquarium for the summer and then travel around Lake Superior.
