This is an interesting take on these little critters (not sure if I agree- I just hope he's right):
Zebra Mussels - Pros and Cons by Gary Gray
Going back about 8 yrs ago, when I was first at Lake Erie, I heard how the Zebra mussel was going to be such a hazard and no one wanted them in their lakes. Well, this is only my observation, and mot a study, just common sense theory.
About 2 years later, I then heard how the Zebra mussel was now a major factor in the reproduction of walleyes in lake Erie. this was due to the fact of how the mussel filled in all the spaces between the larger boulders on the reefs to turn them into a large gravely like flat, which in turn, provided a perfect spawning area. How much better can this get.
Well, then I heard the excretion from the mussels, also provided a food source for the walleye fry. Well, I now look at the walleye population in Lake Erie, and can only say, It Has Been Booming!!!
I live near Lake Winnebago, which is an inland Lake, and has water flow to the Great Lakes. We all know that the Great Lakes are full of Zebra Mussels, and somehow, make their way around. Zebra mussels have now been reported in Lake Winnebago, and the DNR here are worried about them. I say, let them be, look at what it has done for Lake Erie. These little mussels can and will filter the water with the best cleaning method possible. If they can turn Lake Erie into a clean looking lake, just imagine what they could do elsewhere. The DNR at lake Erie, claim the zebra mussel will filter the entire eastern basin of lake Erie within 3-5 days, unbelievable!!! With all this goodness coming from such a small creature, why all the worry?
Here are the only Con's, which create the worries and concerns of local DNR.
1. They will plug up water intakes.( this will create a job for someone)
2. They will clean up the water so much, that weeds will grow.( Great, then the fish will have habitat, fishing can only improve)
3. They will destroy freshwater clams,( no one clams anymore, and in most cases, clams weren't present anyway)
For every Con, there is a Pro, so we might as well accept these little creatures, use them for their goodness, and learn something from this godsend, they are only here to CLEAN UP what we have polluted. Let's let them do their job!!
