Commercial and sport anglers received mixed news this past week regarding the status of Sacramento River fall Chinook and Klamath River fall Chinook – California’s two largest Chinook salmon populations. While adult returns of both stocks were well below minimum escapement goals in 2017, and projected abundance for both stocks is modest compared to historic averages, state and federal fishery scientists reported an increase in the number of jacks (two-year-old Chinook) that returned to spawn in 2017. Higher jack returns, as seen in 2017, can indicate the potential for increased abundance of adult (three years old or older) Chinook for 2018 fisheries.
