Populated Puget Sound Sees Stark Shifts in Marine Fish Species

The most populated areas of Puget Sound have experienced striking shifts in marine species, with declines in herring and smelt that have long provided food for other marine life and big increases in the catch of jellyfish, which contribute far less to the food chain, according to new research that tracks species over the last 40 years.
