Skyrise -

To be fair we should remember that the adult pinks and coho that returned (or did not) this year enter the salt in the spring of 2016. The bulk of this year's chums entered in 2014. In addition the pinks, chums and coho all have different migration patterns as forage behaviors so it is not unexpected to see differential survivals as measured against the normal between the 3 species.
