It was just a routine day at work for biologist Doug Killam - until he pulled this whopping 4ft-long salmon out of a Californian creek.
Mr Killam had been conducting a survey of salmon when he came across the monster fish which had died after spawning.
According to his calculations, Mr Killam determined that the live weight of the fish was 88lbs (6stone) and was between five and six years of age.

Mr Killam said: 'I have counted tens of thousands of salmon during my career, and this is the biggest I have ever seen.'
The fish was found in Battle Creek, a spawning tributary of the Sacramento River near the town of Red Bluff.
Tall tale: Mr Killam shows off the 4ft-long fish
The fish is a pacific salmon, which die after spawning, so counting the dead carcasses is a common method to estimate the numbers of salmon spawning in each stream.
However most of the spawned-out salmon found on such counts weigh between 20 and 30 pounds.
