The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
In terms of migration there is one form we really haven't discussed much. Human intervention. I have mentioned elsewhere that I'm re-reading Charlie Fox's classic, "This Wonderful World of Trout"...In the chapter "The Other Side of Angling" there is a discussion of transplanting mayfly eggs from one watershed to another. They did it from 1947-49.
For three years a group transplanted Green Drake, and a few Brown Drake, eggs into Yellow Breeches, Big Spring, the LeTort, and Cedar Run.They actually had correspondence about what they were doing with Edward Hewitt,Charles Wetzel, and Dr Paul Needham.
There is a discussion of this practise taking place in England with Hewitt writing about the keeper of the Test, Lunn's preferred method for transfer. They also mention an attempt to transplant mayfly eggs from England into the Neversink...(What would folks think of this today?)
doesn't the same thing apply to manufacturing trout streams such as Michigan's AuSable? It's a Grayling stream that was converted by man.....

I'm wondering if they still do it in England?
caddis can really catch baetis?
This practice supposedly increases baetid populations while reducing/limiting caddis populations.
What's this?! Speciesism...Don't get me wrong, I loves me them baetids, but what's wrong with a caddis?
It somehow seems to me that instead of husbanding fish and raising aquatic insects that a really healthy stream would take care of itself.
How "wild" is wild these days? Are we pretending? Is it really only about how many and how big? We have engineered a zoo. I love to fish the Mason Tract that the South Branch of the Au Sable runs through because it "seems" wild...Somewhere in the back of my brain I still know how to get back to the car, the cooler of sandwiches and beer, and a clean warm bed at the Lodge. It's play.
Some Years ago, he trout population on Michigan's AuSable took a big hit seemingly over the course of one season.The year it really showed up was 1989. Populations have never really recovered, at least not to the levels they were before that. Lots of theories were advance; nothing conclusive. john Norcross, a retired fisheries biologist commented: "We may be seeing the tail-end of a failed experiment." That's always stuck in my mind.
