Should dams in the lower Snake River be breached to give Northwest salmon a better shot at thriving?

Is the U.S. Army Corps of Engineers' practice of carrying fish around dams as they head toward the Pacific Ocean helping them survive?

A small Boise company that quietly has been designing and deploying fish-detection systems for nearly two decades is helping answer those questions.

Biomark Inc., with about 20 employees, is busy creating systems to account for fish as they migrate. The company, at 703 Americana Blvd., also implants fish with half-inch chips that transmit data when they come within range of antennas the company installs in streams or hatcheries.
