Mail Tribune –
Standing in lower Jackson Creek with a long electric wand in hand, Ryan Battleson asks fellow state fish biologist Pete Samarin to turn on the electroshock contraption on his back.
“Set me to tickle, not stun,” Battleson says.
Tickle it is, and later a small pulse of electricity jolts out of the mud a 3-inch version of perhaps the most fascinating yet least understood anadromous fish in the Rogue River Basin.
This young Pacific lamprey, called an ammocoete and as much as seven years away from becoming the parasite of the Pacific, swims to the surface and is netted by Samarin for quick identification and release back to the mud.
