Grass carp are not legal in Michigan. But at the Lake Leader Institute the fish professor showed a photo of them, (I was the only one who could identify the fish, ya!). I asked him if they work, and he said yes. That is all I know.
Lynda,
You're DNR doesn't allow them because they are afraid they will go where they are not supposed to be and decimate native vegatation. At the same time they say they don't work. Sounds to me like someone is trying to have it both ways.
What's really interesting is an MDNR person spoke at an aquaculture meeting I was at and said their digestive track is so short the vegatation they eat just shoots right through virtually undigested.
Here's the digestive trac of a grass carp. Does this look so short to anyone here that the vegetation shoots through virtually undigested? Or perhaps it is a relative thing and this is short for a fish that specializes in vegetation?
