This week a unique intersection of art and science is on display in the Duluth community. Catch"Black Gold: Lake Sturgeon Zine Release and Art Exhibit," at Prøve Gallery with a gathering and panel discussion about the most ancient fish around - the sturgeon.

You can see over 40 sturgeon works of art on display in large format at Prøve Gallery plus pick up the zine, a printing off all the images. All proceeds from the sale of the zine go toward traveling this exhibit to communities on the Great Lakes including this Duluth show.

The aquarium needs cleaning and the kids have lost interest in the fish.  Or the frogs. Or the gecko. 

But flushing or dumping everything outside is a bad idea for two reasons:  one, it's inhumane for the animals and two, it's a really bad idea for the environment.

The same hardiness that makes milfoil and goldfish such great aquarium dwellers means they also excel as  invasive species.

It was a plot (almost) worthy of a Sharknado-type movie: hundreds of goldfish inhabiting the UMD campus's Rock Pond back in 2004.

But folks dumping their unwanted aquarium fish and plants in local waters are a real-life nightmare: in addition to the cruelty of dumping fish into an environment they're not suited for, if they do survive, they and the plants become invasives who may also spread diseases.

Diane Desotelle of the Minnesota Pollution Control Agency says it's a pretty good time to be a fish in the St. Louis River.

But it's going to get better. 

Through a network of unique partnerships and collaboration, the clean materials the US Army Corps of Engineers is dredging from ship channels in the harbor will be repurposed in the river to create better habitat for fish, including muskie, northern pike and walleye.

If you're a Wisconsin resident and you have a thought or two about the state's management of wildlife, fish and habitat - for game and non-game - the public comment period on two new plans is winding to a close.
