Yes, groundfish regulations differ throughout the state. Here are some resources that will help with your boat-based groundfish fishing season: 

• CDFW Groundfish Web Page: Provides an overview of groundfish management, rockfish ID flyers, FAQs, and other resources that will be beneficial for the groundfish season. This Nearshore Rockfish ID flyer may help anglers recognize fish that may be off-limits. 
• Recreational Groundfish Regulations Summary Tables: Provides detailed tables summarizing fishing regulations for the each Groundfish Management Area in the state. The files can be downloaded to your phone for quick access. 

CDFW works together with NOAA to create sustainable fisheries. The links below will be helpful if you have a separate GPS device for your vessel. 

• NOAA Depth-Based Boundary Lines Data Point Files: The Rockfish Conservation Area lines are in federal regulations and the National Marine Fisheries Service has a website that talks about the various groundfish closures where you can download a CSV file with the GPS points. If you own a GPS, there are free websites that can convert the CSV file into whatever file type is used by your brand of GPS. Most GPS manufacturers have information regarding how to load this information onto their devices. Please check with your GPS manufacturer’s website or your owner’s manual if this is something you are interested in. 
• The latitude/longitude coordinates defining the 50 fm RCA line for the West Coast can be found in 50 CFR 660.72(a)
