Invasive Signal Crayfish taking over at Jeanes Pond.
With a couple of hours in the afternoon to spare, I drove down to Braybrooke’s Jeanes Pond this week for a test session, to see if the tench and carp were still feeding. A light drizzle was falling, despite a temperature of 24 Centigrade, creating a very humid atmosphere, that saw me ready to strip off to my tee-shirt by the time I’d reached peg 16.
I mixed up a groundbait of liquidised bread, ground pellets and hemp, with a covering of strawberry flavouring, this damped down to allow it to be pressed into a baitdropper, the idea being to drop the feed to the bottom away from the many hungry fry populating the surface layers. With a heavy 2 gram antenna float to a size 14 barbless hook attached to the baitdropper, I dropped a line of feed at 6 metres out and was ready to fish, punching out an 8 mm pellet of bread and swinging it out over the the drop off. The float settled, then raised and I struck, feeling a roach bouncing away close to the bottom.
Not a bad roach to start with. Another 8 mm punch on the hook and the float lifted again, this time the elastic absorbing the initial run from roach number two.
Better by two ounces, this was encouraging, as the three inch fry were not getting down to my bait, which was just resting on the bottom, with a No 4 shot six inches up from the hook, the fish lifting the weight as they took the bread, this enough to raise the antenna, while the bulk of the shot remained steady. This is a classic tench rig, but it works perfectly well for fine biting roach.
A few smaller roach followed, then the bites got fussy. This was not going to plan, I expect the bites to become more positive, not the opposite. Fine bubbles were rising from the groundbait, but the float was only trembling. Often the bait was gone. More baitdropped feed went in. The surface was a mass of bubbles, but the roach got smaller. There was no sign of a pike in the swim. I missed a couple of runaway bites, then…………..

This was the cause of the fine bubbles. Crayfish marching across the bottom to feast on my groundbait.
I put an extra length on my pole, increasing it to seven metres and cast beyond the bubbles, letting the bait fall through. The float bobbled, then lifted. I was playing another roach.
I decided against the baitdropper and threw in a couple of squeezed up pidgeon egg sized balls to keep the roach interested, hoping not to attract the underwater army of crayfish. Another decent roach followed.
Feeling that I’d cracked it by fishing further out in deeper water, I put out another firm ball and caught more roach, some small that went straight back. The lift method was working well, then another crayfish with a death wish. They were following the groundbait.
I put on another joint, stopped feeding and hooked a better roach on the drop, but lost it before the landing net. Another dithering bite and no bait. Then my third cray. A lift bite followed with a better roach again. These roach were down there, but the crays were getting there first.
After two hours, the Jeanes Pond of old would have been producing one of these roach a cast, but now it was a lottery. At last a tench bite, the float bobbled and slowly sank away to the left. I lifted into my fourth crayfish. That was it. I packed up.
I had always thought that crayfish only ate meat based baits, having stuck to the bread on other waters that were infested with crays and never been troubled, but now will have to try a different mix of groundbait, as they seem to love mine.
Pulling out my keepnet, there was not much to show for the afternoon, although I had managed to avoid the tiny roach. Maybe next time, I’ll take a bucket and stick to catching the crayfish.
