Kenai king trouble

Boy, do things sound awful on the Kenai River in terms of Chinook salmon returns.

Here's a news release announcing severe sportfishing restrictions, with this ominous paragraph:

Through June 18, all indices used to assess abundance of early-run king salmon in the Kenai River indicate the 2012 run is the lowest on record. Given the unprecedented low number of early-run king salmon, the department has determined that additional mortality associated with catch-and-release fishing cannot be justified.
