Friends of Steve Irwin say the Crocodile Hunter would be horrified by the recent slaughter of stingrays in south-east Queensland.
The Department of Fisheries is investigating the slaughter of at least 10 stingrays at Hervey Bay and Deception Bay, north of Brisbane.
Irwin was killed last week when a stingray barb pierced his heart.
Irwin's close friend and business manager John Stainton has condemned the attacks.
"I'm absolutely horrified to hear about the slaughter of these stingrays and I know that Steve would be absolutely disgusted," he said.
"This is something that he would never want to hear about.
"Any revenge on any animal, no matter whether it's croc that's taken somebody or a shark that might have taken somebody used to absolutely turn his stomach."
Mr Stainton says Irwin would not have wanted people to harm stingrays to avenge his death.
That's right, a stingray killed Steve Irwin, so people decide to go to war with completely different stingrays. They do have chemical weapons, after all.
63% of Fox News viewers believe that the slaughtered stingrays supported Irwin's killer.
