    Default Seward silver life cycle

    Just curious as to the life cycle of this fishery. If the fish are planted in the lagoon or at Lowell point in 2014 will we be seeing them return in the summer of 2015 or will it be 2016?

    Coho spend 18 months at sea. If they are planted as true "smolt" and not fry in 2014, then they will return in the summer of 2016.

    Generally speaking yes, but some coho spend much longer in the ocean than others. Some return as jacks after only a year, and some don't return until spending several years in the ocean.

    Coho have a more exact duration at sea compared to sockeye, chum, or kings.

    Specifically, look at the coho tables on pages 109-117. They are all one ocean "check"

    I said some, not all. Don't you mean all one river? Obviously they all migrate to the Pacific Ocean.

    No, he means they all have one ocean check when aging the scales. I will go out on a limb and say 98% of returning coho are 1 year River 1.5 ocean fish (excluding jacks).
