Welcome to 2010!
You will now be required to "register" as a recreational fisherman in the National Saltwater Angler Registry starting January 1, 2010. Generally speaking, all fishermen who are fishing in tidal waters will be required to register, unless they are fishing on a head / charter boat. The registration is free and can be performed online. However, there are a few different exceptions, notably if you are 16 years of age or younger, or currently have a Highly Migratory Species (HMS) tuna permit.
NOAA has set up the following website which provides all the details. Simply click on the "Do I need to register?" button on the top of the page and it will walk you through the process. If required, you can then register online.

The next step, starting in 2011, will be to purchase a saltwater fishing license from the state you are fishing in. For those in Massachusetts, there will be a $10 fee. The Massachusetts Department of Marine Fisheries has also set up an informational web site where you can learn more about the license process and rules.
