Quick off the mark there Noel
When I was growing up we fished in the summer and shot in the winter and also set snares anything we shot or caught was eaten nothing was wasted. If we had more than we could eat or use there was always a hungy neighbour.
You would have been though at the very least odd if you caught a fish of takeable size and did not chap it. Money and food was tight in those days for working class people.
I also think that a lot of folk who shoot and fish still have the deep seated hunter gatherer instinct , I also think that is why some fishermen have an unexpalined 6th sense and why good fisherman can often outfish someone with equal technical skills, I think Falkus describes it in one of his books.
That said we have no real need to kill fish or fowl these days, but again the hunting instict is still stronger in some of us.
