California increases salmon spawning to make up for drought
In an effort to blunt the devastating toll California’s extended drought has taken on the state’s chinook salmon population, state and federal fish hatcheries in Northern California are spawning millions of additional salmon smolts in order to increase their odds of survival. The state’s prolonged drought has left many of its dams and rivers unable to supply the cold water currents wild salmon require for their eggs to survive. So, hatcheries are trying to make up for nature’s dry spell with human intervention.
