I have also read about hunts offered in Paraguay. I think the hunt is similar to a US puma hunt with hounds...I would like to try baiting one too!
I saw a woman on natgeo channel radio collar one in Brazil today, first chased it 7hrs and it seriously injured a hound then they caught it on another attempt.
I am certain many jaguars are killed every year in ranches and farms following the international SSS rules (shoot, shovel, shut up)
