A large crocodile that has been taking dogs and stalking people in the remote community of Daly River in the Northern Territory has been captured by wildlife rangers.

NT crocodile management ranger Tom Nichols said the crocodile measured 4.3 metres but was once larger as about 50 centimetres was missing from its tail.

"A trap was set by the local police at Daly River due to a report of a problem crocodile which was taking dogs from the community," he said.

"This therefore poses a threat also to the human population in that community, especially the young kids.

"It is an ongoing problem there unfortunately."

NT Police said there were also reports the crocodile had stalked fisherman.

Daly River is a community of about 500 people located about 220 kilometres south of Darwin.

The crocodile was captured near the Mango Farm boat ramp.

Mr Nichols said the trap was set on Friday and the reptile was captured late on Sunday, prompting the crocodile management team to arrive on Monday.

With the help of local police, the team moved it to a crocodile farm.

While the crocodile did not try to attack any people in the area, there was a concern this would eventually occur, Mr Nichols said.

"You know what they are capable of doing but you never know what they are going to do," he said.

The crocodile is expected to be used for breeding in a crocodile farm.
