What I found so objectionable in all the ‘position papers, press releases, and literature’ were the wholesale assumptions made.
First, the numbers were ‘low’ where fishing causes were concerend. Extremely low when you compare it to all the fishing hours and tackle used. Yet, just because we use ‘lead’, we have to be causing irreparable harm to the bird poptulations. No data listed came close to even suggesting that.
Second, they assume that we are all clumsy and irresponsible. EVERY paper on the subject points out, usually in the primary paragraph, that split shot are small and anglers routinely drop them in bunches and don’t pick them up. It happens, sure, but the literature makes it sound like this happens more than it doesn’t happen, and that we are just scattering these things all over the banks of lakes and rivers without even bothering to bend down and retrieve them…one way they justify their ‘extrapolation’ of how much lead gets into the environment.
That is another thing…their unproven theory on how much lead is ‘expended’ into the environment. They take what is PRODUCED each year and decide that most of it is expended because people buy more each year. I know a lot of fishermen, both fly and conventional, and I deal with a lot of novice anglers (not fly fishermen, just folks who may want to catch a stocked trout or two while camping).
I know where most of that lead is. It’s sitting in tackle boxes in garages all over the country. Until it gets thrown out…some of it sits for years, but most of it ends up in the trash. My ‘theory’ is just as valid as theirs is, but it’s never even considered in the ‘studies’. They just state the ‘amount’ as fact and then go on and complain about what is, bascially, a made up number.
And, nothing, no one thing listed, made me even consider that fly fishing with lead in your flies or crimped onto your line is responsible for even a statistically plausible level of damage to bird populations anywhere.
Our bait and jig fishing brethren may be causing a VERY few deaths, but it’s likely that we, as fly fishermen, are not.
