The UNH Large Pelagics Research Center is running some workshops where they train fishermen the correct techniques for handling, tagging & releasing bluefin. They also distribute tags & tag sticks at the workshop.
Unfortunately, there is no workshop scheduled for RI/SE MA/CT. However, they will come to you if you put together 10 people. This seems like it would be easy to do. Who would be interested in attending this type of workshop? Who has an idea of where it could be held? (kind of depends on how many). Post up here if you're interested & where you're located.
Here is a link to workshop info:
