So Bob Penney wants to have the Kenai River Chinook listed as threatened or endangered. I do not believe this will happen. However, if it does, it would most likely single out the early run. But just for fun, lets pretend that all Kenai kings are listed under the ESA. This means all in river fishing targeting kings would cease. Including catch and release fishing, because any alteration in behavior would be considered a "taking" under the ESA. Any activity that targets kings would be forbidden. However, otherwise lawful activities, such as setnetting, dipnetting, and bank projects could proceed under an "incidental take" permit, that allows for the taking of kings that are incidental to say, gillnetting sockeye.
This is like detonating a nuke on the guides and Joe fisherman, but will unlikely make much difference to the ESSN fishery and PU fishery. The inriver sockeye, silver, and pink fisheries would probably remain untouched. The saltwater troll fishery would likely be closed.
If you or anyone you know is a Kenai River guide, you should be very concerned about this.
Also, when we come out of this period of low abundance, good luck getting these fish delisted. It will take years. In the meantime, everyone not associated with the king fishery will continue on as if nothing happened.
The law of unintended consequences will prevail. Just my two cents.
