Rich - I'm not sure the petition asks for signatures.

Not having been out there to see a copy for myself I'm only guessing that it simply asks that the readers contact the WDFW with their concerns.

For example:
"Catch and release is not needed for conservation. It will only allocate away from the current class of fishermen who may want to keep some of their fish, to another class of fishermen who do not. Neither group has it necessarily wrong, and the present system of extensive catch and release sections plus the five fish annual limit is a good and working compromise."
