I came across this series of articles on invasive species in the Great Lakes and I thought many here would be interested:

"The Great Lakes have become a giant outdoor biology experiment -- with no one in charge.

In the space of a few decades, an evolutionary snap of the fingers, vast populations of foreign fish, mussels and other creatures have invaded and damaged irreversibly an ecological design that took thousands of years to evolve.

These unwanted guests in the largest freshwater system on the face of Earth have muscled out native species, killed thousands of loons and other migrating birds, devoured food resources, clogged water-intake pipes and begun to spill into many of North America's premier interior lakes and rivers.

Many scientists say the invaders are a worse problem than the industrial contamination that fouled the Great Lakes in the 1960s."

Bob,

A really great resource of information. Thank you for sharing. It'll take me a while to get through all that information.

Believe it or not most of the Great Lakes trolling guys are complaining about these.....I'm seeing more and more every year on the Milwaukee river.

Invasives can really make a mess. Carp, weeds, mussels, Gobies, and more. Lots of 'adjusting' to do in the ecosystem. nasty critters all. I just hope the Great Lakes can take the invasion in stride.

Glad to make a contribution. I haven't been able to fish often lately so I've been living vicariously through the reports here

I've read through most of the series and as with the majority of news, there's a touch of sensationalism present. Nevertheless, it's a significant issue. As Steve said, I hope the Lakes adjust - well actually, I know they will. The question is, how much and how will affect the species we like to target?
