With more species on their way Governor Snyder has announced that the week leading up to the 4th of July is now considered Aquatic Invasive Species Awareness Week in Michigan.

Revived senate bill would help protect the Great Lakes from invasives

In Washington DC, a bill that would help protect the Great Lakes from invasive species has been revived by the Senate, and sent to the House for a vote.

The Vessel Incidental Discharge Act, or VIDA, would set a national precedent for controlling boat ballast water that enters the U.S.

The bill was revived when Senator Gary Peters of Michigan added an amendment that would require all ships that enter the Great Lakes through the St. Lawrence Seaway to dump their ballast water prior to entry.
Ballast water is considered to be one of the biggest doorways for aquatic invasive species to enter our waterways.

Invasive snail kills birds with parasitic help

In a scientific supermove U.S geologists and Michigan biologists are combining their power to map out areas impacted by invasive species.

In an ironic twist on the food web, an invasive snail has become a bird killer.

The faucet snail is a half inch brown or black creature. It’s also the carrier of a lethal parasite.

Dr. Don Uzarski is a biologist at Central Michigan University. He says this snail is bad news.

“It’s an intermediate host for a parasite. What happens when waterfowl consume an infected snail, the adult trematode then attacks the internal organs of the duck, ultimately killing the organism.”

In an attempt to control the faucet snail populations, biologists from CMU and geologists from the United States Geological Survey have combined efforts to map out known habitats.

Uzarski says so far efforts to kill the snails have not made a dent in their numbers.

At this point the parasite is only known to effect waterfowl.

DNR releases a video to identify a new invasive species of fish

For fishing aficionados it’s important to be able to distinguish between the different species of fish.

Now the DNR has put a tutorial online to help people distinguish between a native species of fish and a new invasive species that may find it’s way to the Great Lakes. Continue reading
