Nearly 6000 Mary River cod were released last December.
“Any endangered species or recovery programs are supposed to be driven by the federal government but the feds have never done anything about the Brisbane River cod,’’ he said.
“So we picked the ball up. We said we need to do something on the Upper Brisbane. We’ve got about 150km of river up there with no apex predator in there since their extinction in 1938-1940.
“We ran a program, accepted by the Queensland Government and Federal Government, and it was the first program like this driven by a community group.’’
The current target species is Mary River cod which have better survival prospects.
