I am a grad student studying invasive species and I am working on building a collection of native Gambusia (affinis and holbrooki). If anyone knows of places in the southeastern US that would be good for collecting I'd appreciate the input. Preferably, I would like to collect from streams/rivers/lakes and not from man-made pools or other places they may have been transported to for one reason or another, but I realize that may be a challenge. If anyone has Gambusia they could collect and send to me I would be ecstatic and can discuss it with you further. I am located in Georgia and will be doing some collecting trips this fall. Thanks.

I think you'll have good luck collecting these in streams, rivers, lakes, roadside ditches, drainage ponds and some mud puddles. I have yet to see a permanent body of water in South Carolina that wasn't infested with these.

I am also in Athens, and have access to a few spots where you can collect Gambusia holbrooki. I have a few spots where they live in pools of tiny streams. I also have access to several small spring-fed ponds built in the 1950s if you are at all interested. I lived in Knoxville, TN for 5 years and know of a few good G. affinis spots if you are interested in traveling that far. But as mentioned, you'll have a hard time not finding any...
May I ask who your professor is? I am also a grad student..

Gambusia (presumably G. holbrooki) are abundant in brackish ditches and creeks where I am right now on the Outer Banks, NC. I wouldn't think they were imported; nobody stocks skeeterfish in saltwater, right? G. affinis are immensely abundant in any floodplain stream, swamp, or reservoir margin in about the western third of Tennessee. They thin out a bit east of there and may be introduced in the upland areas.

Hi Newt,
Where are you in the Outer Banks? I was in Nags Head back in June and saw gambusia in all of the small ponds/ditches in the Nags Head area.
To the original poster: I am in Lancaster County, PA and I also have a source for gambusia from a local lake. They are definitely invasive here.
