that fish was probably newly released. The probability of that thing lasting through a winter up there is 0. I am still skeptical that the fish was in water that cold.
Pirhana caught in a MN river
- Thread starter ewurm
- Start date
Every summer in a northern state someone catches one and everyone freaks our. Simple fact is come winter any piranha released in one of those states dies.
I think a P could survive even into the low 60s to upper 50s because the climate of paraguay is not too much different then some southern states except alot drier. But my bet would be that what was caught was a pacu.
Rallysman where in Indiana was that pacu caught and Slammer where in Ky are you located?

the piranhas found in paraguay, argentina, and uruguay are pygocentrus sp. "ternetzi" formerly thought same as nattereri, but I have the personal conviction that its a distinct specie.
They're location, colouration, maximum size, cold tolerance, and at some places they over lap with both species this is from an first hand account. And yes, those places the temperature drops down to the 40-50s.
I've seen many fish, if adapted slowly can adjust to taking temperatures well down into the low 60s with just the apparent slowing of metabolism, and no ill effect.
So I'm sure the "ternetzi" could take colder water than that, differing from the northern cousins, p. nattereri which are typically found in warmer waters!
