Found this by way of Midcurrent this morning. It has the trends from 1991-2006 in fishing. Things I noticed:
-Less people are fishing today than they did in 1991 (somewhat surprised)
-Saltwater fishing increased in popularity until 2001 (no surprise there)
-People in Maine, PA and Oregon like to fish for trout. Guess that's why I've lived in all of those states.
The moral of the story to me is that we need to get more people out fishing. I hate finding a crowded river, but if people don't like to fish how can we expect them to protect the fish?
