Taking cues from nature to advance salmon restoration

Some more great research and “lessons learned” about restoring Atlantic salmon stocks.

This is the fourth feature in a five-part series that follows an Atlantic salmon on its journey upstream to spawn in a tributary of Lake Champlain driven by its instincts (and a pickup truck). Learn why this species disappeared from the lake in the 19th century, and how it is making a comeback today thanks to collaboration by partners in the basin.

“I want you to see this structure out here because it has really informed our thinking about the effects of barriers on fish movement,” said U.S. Geological Survey Research Ecologist Theodore Castro-Santos as we walked across the snow-covered grounds of the Silvio O. Conte Anadromous Fish Research Center in Turners Falls, Mass., to check out what appeared to be a swimming pool connected to a long cylinder wrapped in plastic.

“This is the Aquatic Biomechanics and Kinematic Research Station. We call it ABiKiS.”

“You have to step on this footpad to come in and out of this area,” cautioned Scott Frost as we crossed into a roped-off section of the White River National Fish Hatchery. “It has a disinfectant to make sure we don’t drag any contaminants in on our boots.”

Once our boots were clean, Frost, who is the assistant hatchery manager, led me over a row of rectangular structures and rolled up a black curtain to reveal racks of trays alternately labelled with plus and minus signs. Each tray contained hundreds of recently hatched larval salmon.

“These eggs were spawned from wild fish caught migrating from the lake to spawn in Hatchery Brook last fall,” he said. “We incubate the eggs until they get to the ‘eyed’ stage…

Driven by instincts and a pickup truck: An Atlantic salmon’s journey towards recovery — U.S. Fish and Wildlife Service Northeast Region

Reblogged from the U.S. Fish & Wildlife Blog….

That’s how many Atlantic salmon make their way to spawning habitat in Lake Champlain’s tributaries nowadays. Learn why this species disappeared from the lake in the 19th century, and how it is making a comeback today thanks to collaboration by partners in the basin.
