Jack Dempseys breeding in South Dakota hot springs

I recognize that picture; that's my local farmer's market. Or at least it looks like the farmer's market outside of Greensboro on the Winston-Salem side. When I went there a few months ago there was water hyacinth in tubs and fountains. I noticed it and commented to my friends about it but didn't do anything else. It's already here and has been here for a long time. http://nas.er.usgs.g...s/ei_crass.html There is a long history of people putting terribly invasive species in ponds and not batting an eye. *coughs* goldfish. The one good thing is that plants like water hyacinth don't usually stick around. It's from Brazil and not really capable of overwintering well. The hot springs and warm water factory refuges mentioned in the article are not really all that common. Tropical species usually die.

But, it is important for us to know as native fish enthusiasts that there is this perception out there about aquarists... true or not it doesn't matter... it is a perception that we have to be careful of. Some of us like to keep fish in aquariums. Native fish. And we need to make sure that we are living to and promoting only the highest standards. So while I don't agree with this guys attitude, I am interested to see it and understand it.

I have also heard from a state hatchery worker that a local man near Hot Springs has a hot spring fed pond in which he keeps tilapia. Hard to believe in a state where winter temps often hit 20 below zero.
Maybe I should take a collecting trip down there to see what sort of surprises I can find. Might be a miniature Amazon.

BTW, I couldn't say that it is KNOWN for the piranha breeding population, but if you go there you most certainly stand a chance of catching one. It is claimed that they aren't breeding, but I have seen 3 fish from that lake, 2", 3.5" and a 5" fish. I assume they would be breeding. I haven't fished there in 10+ years, but I again assume that with a constant temp of 78 ish, it easily could sustain populations.
