I think commercial salmon fishing should be targeted and let them recreational fishermen have at it at them salmon. They can even make new slot limit rule plus 1 salmon per week rule or something.
They already banned the abalone harvesting in california for a few years now. I'm not too sure what is the count on that and I'm hoping their population will thrive for a season opener again.
Sometimes they are making rules that doesn't make a difference. Like with abalone, they are competing with them sea urchin for food. You know what is over populated and hardly anyone is eating them? Yep, sea urchins all over the place. People should harvest sea urchin so them abalone to have a chance to thrive.
