Hey, I'm all for creating parks and open lands. That had nothing to do with
my argument regarding habitat improvement for exotic fish. Open lands and
parks can be just as easily created for native fish too.

I'm sure that Maryland is not the only place where habitat improvement for
exotic species goes on.

If I was given the choice between a degraded stream with nothing versus one
with exotic trout I would go for the trout. However, I would strongly push
for works benefiting native species also irrespective of whether or not they
are trout or a non angling species. An alternative, compramising position
would be the improvement of habitat for both.

I was not criticising the folks asking for information (not intentionally at
least), merely commenting on the irony of it. I was not trying to be
specifically critical of _this_ project, just the philosophy of spending
money that appeared to be strickly focused on exotic fish (from an aquatic

But no one ever seems to work on this aspect or push the concept. It is
always just assumed (if that much) that native species, or at least some of
them may benefit. Probably some do. Imagine what some innovative research
might be able to show in improving overall habitat restoration work for as
many species as possible, not just one.
