A new nonprofit is training citizen scientists to collect data on fish in the Great Lakes, which could be a game changer for research in the region and help prevent the establishment of invasive species.

Scientists have been worried about the lake herring population in Lake Superior recently. In fact, last year they warned it could be headed towards a collapse.

Lake Superior is the only Great Lake that still has a significant population of herring - or cisco as they're commonly called.

This fall, new rules protecting herring took effect in Wisconsin and Minnesota and things appear more stable. But there may still be a big problem lying beneath the surface.


This Saturday, 35 baby sturgeon will be released into the Kalamazoo River at a sturgeon release party. It’ll be in New Richmond and it’s open to the public.

Illinois became the first state in the union to ban microbeads, the tiny bits of plastic found in consumer products like skin exfoliants and soap.

As NPR's Cheryl Corley reports, environmentalists say that when microbeads wash down the drain, they're usually missed by filtration systems, which means they become food to fish and other wildlife.

Cheryl filed this report for our Newscast unit:

From the shoreline at North Avenue Beach in Chicago, the blue water of Lake Michigan stretches as far as the eye can see. But beneath that pristine image, there's a barely visible threat, says Jennifer Caddick of the Alliance for the Great Lakes: microbeads.

These tiny bits of plastic, small scrubbing components used in hundreds of personal care products like skin exfoliants and soap, can slip through most water treatment systems when they wash down the drain.

Monahan’s Seafood Market in Ann Arbor carries soft-shell crabs from Maryland, Alaskan salmon, and Florida red snapper.

But at the moment, they’re fresh out of Great Lakes whitefish.

Bernie Fritzsch manages the fish market.

“We’re hoping to see it today, but we haven’t seen it for the last week,” he says.
