TR: Bull Trout Presentation

diadromous = live in ocean, spawn in fresh (anadromous) *or* live in

amphidromous = moving from normal fresh or salt to the other water to
eat or survive drought but not to procreate. perhaps?

That's a new word for me, it sounds about right, I'd need to understand
when it's used, but I think that it probably applies more to cutthroat
and Dolly Varden with their sneaking in and out of the estuaries. Bull
trout use reservoirs like salmon use the ocean, they move out at a
tender age, and come back for sex. The Bulls in the Hoh seem to
include both amphidromous and anadromous fish.

Thanks
