The following Tacoma Public Utility site has graphs showing 2017 returns for various hatchery and natural origin fish.

It is interesting that most natural origin species had returns comparable to the ten year average while all hatchery origin species except springers had a dismal year compared to the ten year average. Two reasons jump out but there could be others. One is that the hatchery release has been cut substantially and the other is that natural origin fish survive difficult ocean conditions better than hatchery fish. Does anyone have a good answer for the discrepancy in returns?

If the later reason is valid it has implications for the legislator and a number of fishermen who advocate ignoring HSRG (and potential ESA listings) and turning Puget Sound and Willapa bay into hatchery fish farms.
