The ten-foot-long monster has been the stuff of local legend for more than 40 years, thanks to its immense size and bizarre bulbous pink nose.
But on Tuesday it was hauled in for the first time - and Nick McCabe, the 19-year-old who brought it in, has become something of a local hero.
Nobody knows the origins of Pig Nose or his distinctive 'snout,' but the gargantuan beast is believed to be around 80 years old, based on its size.
'His name is Pig Nose and you can see why - he damaged his nose 40 years ago,' explained Jeff Grimolfson, who works with McCabe at fishing tour company River Monster Adventures.
'So when his nose healed, it looks like a pig nose.'
The beast 'has been the talk of fishing and sporting goods shops for years,' he added.
But although the sturgeon had been tagged and microchipped before in the past, no fisherman had managed to haul the beast in until Tuesday.
