Rob Clarke was alerted to the problem on a day out with his son when he saw a group of lads armed with buckets and bin bags pulling a large net through the water on the Leeds/Liverpool Canal in Lancashire.
And on another trip to the canal’s Reedyford Road stretch he found a wooden stake pushed in the ground with a length of thick line attached to a rusty sea hook and a mackerel head.
He found another eight similar lines in a 200-yard stretch, two of which had dead pike that had swallowed the bait.
Areas that had previous produced lots of sport with pike have given him nine consecutive blanks in the past two weeks.
