At long last, coho salmon making return to northeastern Oregon river

The fish, raised by state wildlife officials in a hatchery outside Portland, were trucked 300 miles inland in nine water tanker trucks equipped with highly sensitive oxygen and temperature sensors and a bubbling system that mimics a river’s current. Now in the Lostine River, they must turn around and swim 600 miles to the Pacific Ocean over the next month and then swim home after a year and a half in the Pacific Ocean feeding and growing.

Alaska students schooled on salmon life cycle

Students who participate in Salmon in the Classroom curriculum start out raising coho salmon eggs in the fall, learn more about fish with dissection lessons, and practice catching fish during the ice fishing field trips before coming together in the spring for a celebration during which mature fry are released.
