Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Where to get Fatheads in NE FL

One thing to watch with the GSH. If they are in a BOW that has invasive plants, there's a good possibility of transferring those plants to your pond along with the GHS.

I relocated over 200 GSH between 6" and 9" to my pond, and had Eurasian Water Milfoil show up a year later. A year after that I was visited by a bunch of geese that I didn't chase away for a few weeks, and I think they brought even more of the stuff with them, either as pieces or in their poop.

I think the GSH had some milfoil seeds in their gut and pooped them into the pond. I didn't transfer any of the water from that BOW into my pond.
