Trotted maggots gave Adam Perna a haul of five grayling including three two-pounders to 2lb 9oz.
The Oxfordshire rod adopted a roving approach on a southern river and took fish throughout the day before connecting with his new personal best an hour before dusk.
He said: “In the 2lb 9oz fish's case I had caught a few brown trout that had disturbed the swim so I fed for 20 minutes, spraying maggots, and then ran my float through again and the grayling took the bait after the float being in the water for a couple of seconds.
“It looked huge being a male fish, and put up quite a scrap. The difficulty was drawing the fish close enough to net with only a 1lb 4oz bottom on.”
Adam used a five-AAA chubber float, a size 22 hook and 4lb mainline.
