Helping young salmon may start with a darker night. I'm Bennett Blackwood. In Seattle, U.S. Geological Survey researchers are studying how city lights change life underwater. Young salmon use darkness as cover. Extra light can give predators more time to spot them. Research scientist Tessa Code explains the question. So our hypothesis is that artificial light is reducing salmon survivorship because it's making the predators better at hunting them. The team combines nighttime boat surveys with controlled fish experiments. A twenty twenty-six study used a model to compare hunting conditions in Lake Washington and the Ship Canal. It found greater modeled vulnerability in brighter waters. The work could guide shielded lights, warmer bulbs and carefully timed lighting. These are potential solutions, not a claim that salmon numbers have already recovered. It's practical research toward a safer journey to the sea. Good stories every day. Follow Carpe Diem News.
