NANFA-L-- Florida exotics

Just a few notes from my recent trip to Florida.
I was catching up with e-mails this morning and I read a post from Dave
McNeely about invasives, blue tilapia, and he mention Florida. This reminded
me of a revelation I experianced while on vacation in Florida recently.
The Lowry Park Zoo has a Manatee rehabilatation exhibit with large veiwing
windows in a grotto area. Cameron and I were looking-in-the manatees and the
many large fish in the tank with them, when a two foot long red-tailed catfish
swam by. I suddenly was looking-in-the fish from a new perspective and
realized that these fish were exotics and I would wager they were removed from
local waters.These were some large fish and they could do a lot of damage when
introduced to a new ecosystem.
Cameron and I were collecting in a tributary of the Hillsborough River just
outside of Tampa. I was staring into the water-in-all these little
livebearers, when suddenly a 12 to 15 inch long Plecostomus swam right up to
the edge of the water. I was kind of excited about this but a couple of local
fisherman seemed rather nonchalant about it. Of course, they told me they were
trying to catch some nile perch that lived in this particular pool.
