The Ocean Sport Fishing Regulations booklet is always the go-to reference booklet. In the book, you’ll find a table that guides you to regulations (bag limits, size limits, etc.) for specific fish, invertebrate, and marine plant/algae species. We strongly encourage to download the book in PDF form from the CDFW website, and put it on your phone so you’ll have it as long as your phone is with you. However, double check your version before each fishing trip so you know you have the current version (indicated by the version date on the cover).
You can also use CDFW's Ocean Sport Fishing webpage to look at a summary of current sport fishing regulations that apply to your intended fishing area along the California coast.
