As an angler for more than three decades, I was bitterly disappointed to read your story, The reel thing: bid to lure young anglers (The Herald, April 14).

For many years, I went freshwater fishing in Britain and abroad with my father and grandfather. Thankfully now, however, I get as much, if not more, pleasure just being by a river and watching nature instead of tormenting it. There is nothing more pleasurable than observing the salmon leaping.

Then, as now, I was sick of finding discarded nylon filament, either in the trees with birds entangled and throttled or submerged. I found masses of nylon at Loch Rannoch and on the banks and in the trees of the Leven. I, too, lost much nylon in the weed beds of the River Wear, though not deliberately.

Then there is the problem of swans and other birds swallowing lead shot, which poisons them; thankfully, that has been outlawed. It wasn't just environmental issues that worried me, but also animal welfare issues. My grandfather used to permit inadvertently the hook to go right down ripping out a fish's intestines, and I inadvertently hooked salmon in the tongue. This maltreatment of wildlife, coupled with the environmental damage is bad enough. But anglers take the best fish, thereby depleting the breeding stock.

I finally came to my senses and I quit this blood sport in my late thirties. If people must go fishing, I would suggest they use only single, barbless hooks and, when possible, recover all nylon line. Anglers should also use a stronger filament, thereby minimising breakages. In addition, when handling fish, they should ensure their hands are wet. Fish also should not be held in keep nets. And anglers are guilty of leaving considerable litter. The worst offenders are the coarse fisherman, some of whom are very coarse indeed.

Finally, it should be noted that unlike some anglers, fish have brains, are sensitive and have feelings. Your otherwise most excellent report omitted to say that fish are extremely sensitive to disturbance.
