The Australian Marine Conservation Society has called on the Government to install cameras on gill-net fishing boats.
Fisheries campaign manager Simon Miller says the onboard camera would show the public the volume of entanglements.
"Gillnets are indiscriminate killers," Mr Miller said.
"They're very effective at catching fish, but they're largely invisible to lots of other species, like turtles and dugongs and sawfish."
Queensland Seafood Industry says mandatory species training for commercial fishers would further protect marine life and ensure competent handling.
