Tony Gibson was unpegging his bivvy at the end of a three-night session at Bluebell Lakes when he latched into this 50lb 2oz common.
The venue regular, who is chairman of the Northampton Specimen Group, planned his session on Swan Lake to take advantage of low air pressure and big winds.
His prize, the fish known as the Box Common, is one of at least three 50s in the day-ticket venue.
“On the last morning I was actually well on with the job of packing up,” said Tony.
“I was in the middle of unpegging the bivvy when the right-hand rod signalled a steady run.
“It felt like a decent fish when I first bent into it, but came in relatively easily and without much drama, so I had it in close quite quickly.
“When it turned over near the surface, just under the line of the middle rod, I got the impression that it wasn't particularly big.
“However, a minute later it suddenly seemed to grow dramatically as it came up and allowed itself to be drawn over the net cord at the first attempt.”
Tony, who admitted he was surprised at the fish’s weight, fished a spot in the middle of the lake nearly 70yds out.
