Not all Grass Carp hit the news

Quote:"Grass carp have been in the Great Lakes for ... probably 30 years or even more but they've been sterile," said Mark Gaden,

I see this a lot. We think we can bio-engineer a species to fix the problems caused by run-off or another species and we think we can sterilize them and control them. But nature always finds away, thats the entire point of nature: reproduce.

So we have grass carp. And like all carp, they're stigmatized. We won't know, good or bad, until we've peaked at the point of no-return. Thats how these things work out. The carp will establish an equilibrium, or we will see them overtake native and naturalized species.

In the meantime, I suspect the MNR will keep wasting money restocking browns and rainbows which do not seem capable of any kind of equilibrium and should be allowed to die off, and continue to ignore populations of fish that were native but have been mass culled as "garbage fish" or "Invasive species" in the past, like gar.
