About a year ago, on one of my local rivers, I hooked a decent grayling that had me thinking about getting my scales out as I was playing it. Just as I was reaching for my landing net, I heard a plop and watched a stream of bubbles head towards the fish that had just surfaced. To my relief, the bubbles appeared to go beyond the fish. Unfortunately, a big black nose, set of whiskers and some impressive rows of teeth appeared and made the grayling disappear rapidly. For a little while, I was still attached to both fish and otter. It made a beeline for a partially submerged tree just upstream. I clamped up and the hook pinged out of the fish. Mr Otter proceeded to exit the river just upstream and treat me to ten minutes of chomping noises. Once done, it plopped back into the water, swam under my feet and climbed out of the water and sat, clearly visible, just downstream of me. It just watched me fishing for a while and then slowly ambled away.
