HMS permits will list the most recent Bluefin regulations as they can change overnight.
https://hmspermits.noaa.gov/Default.aspNational Marine Fisheries lists the regs for the other tuna, sharks, etc.
http://www.nmfs.noaa.gov/sfa/hms/Linkpages/regulations.htmI could not find a page with the limits on dolphin, but they are 10 per person but no more then a max of 60 per boat. Florida reguies a 20 inch fork length on dolphin, VA doesn't, but it would be a good idea.
