A record number of saltwater crocodiles were removed from Top End waters during 2012.
A total of 314 salties were captured and moved as part of a Northern Territory Parks and Wildlife Commission management plan.
Of those, 215 were taken from Darwin Harbour, including a 4.26m male in May.
Senior wildlife ranger Tom Nichols says 295 were removed from the Darwin region and 19 from the Katherine region.
"This year's total tally is the highest on record, beating the previous record of 306 set two years ago and surpassing the 284 caught in 2011," Mr Nichols said.
"With more than six salties removed from Top End waters every week on average, this should serve as a reminder to the public to be Crocwise.
"This means behaving responsibly in and around Territory waters and not putting yourself or others at risk of crocodile attack.
"The crocodile management team has been able to remove more crocodiles from Territory waters during the past few years through the use of more traps and custom-fitted croc boats that include specifically fitted harpoon racks, crocodile slides, self-draining decks and side rails."
The largest of the 80 saltwater crocodiles removed from Darwin's outer region was a 4.85m male in April.
It was caught at Corroboree Billabong, and was also the largest croc removed all year in the Top End.
"A total of 28 crocodiles have been removed from Territory waterways this month, which is a timely reminder that wet season conditions can lead to the increased presence of crocodiles," Mr Nichols said.
Estuarine crocodiles are common in the Top End and can inhabit any waterways, including freshwater systems, billabongs and low areas subject to flooding.
