I am not sure what the job title is but I remember the NMFS ran some pretty sharp looking patrol boats in the Florida Keys. Maybe I am confusing them with the Sanctuary Patrol in Key Largo....not sure.
FL FWCC handles patrols for the Florida Keys National Marine Sanctuary. They have a really nice 53' aluminum cat, the Peter Gladding. However the NOAA agents down there often ride with them and the Coast Guard.
