MORE than 100 dead animals including turtles, freshwater bullrouts, Australian bass and a water dragon were found trapped in four illegal fishing nets at Jimboomba.
The Queensland Boating and Fisheries Patrol have launched an investigation to find those responsible for the disturbing crime in the Logan River.
Fisheries minister Mark Furner said 120 turtles and even an eagle were found in the nets.
"Most of these creatures were decomposing, suggesting these nets have been there for some time," Mr Furner said.
"Officers even found a White-bellied sea eagle that had somehow got caught in these nets and unfortunately perished.
"I am appalled and sickened by these wanton acts of destruction because they cause great damage to local native wildlife populations as well as fish stocks."
Mr Furner warned there were severe penalties for people who use fishing nets in freshwater systems.
"Those found responsible for putting these types of nets in the river could face fines of up to $131,000," he said.
"I would like to thank members of the public who reported these nets using our Fishwatch hotline.
"Queensland's native wildlife and fisheries resources are owned by the community and everyone is responsible for ensuring they're managed and fished sustainably for future generations."
The Jimboomba Times has contacted the Department of Agriculture and Fisheries for an update on the investigation.
