First, I think we really need to move on. I'm not sure we're getting
anywhere. But I will answer your current questions. (1) when those
fish were introduced, there was no general understanding that they
were likely to cause problems, but ...... . (2) A fish doesn't have
to be a predator to cause problems. The channel catfish is an
omnivore, and it's lethality to the pikeminnow, an endangered species,
has nothing to do with it being predaceous. It is dangerous for the
pikeminnow to eat. Carp likewise are omnivores, and the problems
they've caused likewise don't have to do with their being predaceous.
(3) I don't know enough about how particular ecosystems work to
predict all the problems that a given release might produce, and that
includes a sturgeon. Remember that many of the unintentional
introductions have not been predators. Let's just try to keep
introductions out. Most state agencies that have introduced various
species over the years now generally are-in-least much more reluctant
than in the past.

I applaud your concern and interest in this-in-risk fish. There are
better ways, and it would be great if we focused on those.
