So I was launching on Saturday and saw DFG Clipboarder that I have seen on the sporties a lot. I asked him what their information is used for and he basically said the same thing as Paul. They use it for rockfish quota, determining seasons' lengths, and limits. He said it is also a "general way to keep track of, and manage fisheries." I asked him about MPLA closures and how this information relates, and his answer was that "they get information from many sources." On the way back in I shared my Cuda, Checker, bait and other catches with him. My new philosophy on sharing with them (now that I know why they're there): I will share with the clipboarders I like.
