PORTLAND, Maine (AP) A plan to test the use of a new technology to help endangered salmon in a Maine river that is critical to their existence has been abandoned, at least for now. Atlantic salmon return to very few rivers in the United States, and the most important of those is the Penobscot River in Maine, which is more than 100 miles (160 kilometers) long and runs inland from the state's mid-coast region. As the salmon return to rivers from the sea, they are faced with hazards, including manmade structures such as dams. Fish passages, such as ladder-like structures, are used around the world to help fish around difficult spots so they can eventually spawn.
