To commemorate 25 years of REEF’s Volunteer Fish Survey Project, a group of volunteer citizen scientist divers joined REEF staff and interns, along with co-founder Paul Humann, for a special 25th anniversary Field Survey Trip in Key Largo, Florida, last month. Key Largo is home to REEF Headquarters and was also the location for the very first REEF Field Survey Trip, held in July 1993. The attendees on the 2018 trip surveyed the same sites visited by participants on the 1993 Field Survey, to observe how fish populations have changed over past 25 years.
