Steve Griffin: With a little effort we can slow spread of invasives

There’s two things we tend not to realize about aquatic vegetation, the stuff we call weeds: how important good ones are to the fish we love, and the threats invasive newcomers pose to the lakes we visit.
We pounded the panfish one winter on a small northern Michigan lake. We didn’t realizing until after the following two disappointing winters that we’d fished that first year within and above some bright green, oxygen-producing and resident (if not native) weeds. Those next two years were amid the remnants of that bed, which were now consuming oxygen as they decomposed.
