A study into marine reserves has revealed some good news for fishermen.
The study, funded in part by the Australian Research Council, found that fish numbers are increased in marine reserves where mangroves and reefs are close together.
Lead researcher Andrew Olds said the reserves meant fishermen would be able to catch more fish, even in protected "green zones".
"In Moreton Bay (in Queensland), this translates to more harvested fish, especially yellowfin bream, moses perch and black rabbitfish, in marine reserves," he said.
"These fish move about the seascape and can be caught when they move out of the green zone to feed or spawn."
But this does not mean open season on Queensland's heavily protected coastal marine reserves, Mr Olds said.
Mr Olds hoped the study would influence decisions on the location of existing and future green zones.
