it was on the history channel, it talked about piranhas in the United States. Apparently there is a population of red breast in Missouri, in the lake of the Ozarks. They have caught six piranhas in that lake in the last 3 yrs. Most were large Reds and one was some sort of serra (looked like a rhom). These are documented with pictures as proof. I was quite shocked at how these reds were surviving. In the winter they school around under ground springs. One under ground spring the temperature never goes below 57 degrees in the winter. The reds or pygo's seem to stay around these area's. Are these fish adapting to the cooler waters?

6 catches in 3 years. I would lean toward fresh releases. Don't think they are surviving the winter. Saw that same program a few months ago. I didn't buy into it much. Unfortunatly the masses do.

definitely not pacu's. Someone caught a serra there too. Google it. :)

I thought about fresh releases like you said , but they would need to be breeding them over the winter months , plus a few of those pygo's were a few years old. One pygo looked huge. Wouldn't someone catch on to someone breeding them and releasing them?

They also did a test on 4 reds in an aquarium. They lowered the temp from 75 degrees over a 5 day period to 57.9 degrees and they huddled together. At 55 degrees they lost their equilibrium , but weren't dead. This might have merit to it.

Could be. The other thing if it's only large specimens being caught, there's no sign of breeding.

They could have been released at a big size... Also when they become lethargic for a long time it's not like they come back perfectly normal. Organ failure and brain damage can occur.

That episode was pure rubbish. Reminded me of a trailer park documentary. Those "geniuses" should be banned from documentaries, or anything remotely educational.

Looks like Monster Quest needs more of an audience to watch their big foot shows.

I remember that Serrasalmus species being caught. I also remember telling Fox news it was a pacu. Here's your "Serrasalmus ".

That's not a PACU. Here is the video of the show , exactly at 2.52 minutes, you will see the serra(rhom).

Ok saw it. But they don't say the video is of that fish. I'll see if I can get better confirmation.

I'm digging deeper. I checked with USGS, which collects all non-native species reports in the U. S. the only one listed is: 9/14/2011 red piranha
Pygocentrus nattereri County: Harris (TX)
Drainage: West Galveston Bay (12040204)

And I can say for certain they are correct. That's checking from 2009 to present.
