From NOAA Fisheries Service:

NOAA Fisheries’ Atlantic Highly Migratory Species Management Division launched a new free app for Andriod devices that allows anglers to share information about releasing North Atlantic shortfin mako sharks (Isurus oxyrinchus). Using the "Release Mako" app, anglers can now report live releases of shortfin mako sharks on the water simply by using their Android mobile devices.

For more information visit NOAA’s shortfin mako Android app page. You can download the app at Android Market’s Release Mako page.
