A TINANA fisherman says he regularly spotted the 3.8m croc caught near Grahams Creek at Mungar and kept rangers informed.
"He's been constantly following us around when we're catching barramundi ... he's got pretty good at taking it out of the net," Kevin Greenhalgh said.
Mr Greenhalgh said he had to change his method of fishing and be more cautious as a result.
"We'll have to be aware (of crocs) all the time from now on, not just fishermen but everyone," he said.
The saltwater croc, believed to be male and aged between 20 and 40 years, was caught after a two-and-a-half year search.
The night-long Department of Environment and Heritage Protection operation involved two vessels and four crew members.
EHP senior wildlife ranger Greg O'Neill said the croc was spotted about 9.30pm on Tuesday and after snaring the monster it took rangers three hours to tire it and then rope its jaws.
"I think it's a good result for the community from a safety perspective," Mr O'Neill said.
"He has been regularly transiting through the Maryborough town area."
He said although the captured animal had been calm, crocodiles needed to be handled carefully.
"He's not happy being removed, he's a wild animal and he's a dominant predator of this area, he just wants to get back to the river," Mr O'Neill said.
The croc was expected to spend the remainder of its life at the Koorana crocodile farm at Rockhampton.
Rangers will now continue searching for another crocodile believed to be about 2m long.
