An experiment on the river – Researchers hope fish trap will be safer for wild fish
Fish traps have been outlawed in the Pacific Northwest for decades, but researchers plan to test an experimental trap in the Columbia River in hopes that it will be safer for wild fish than traditional fishing methods.
