What is SMILE?

Size matters—especially for fisheries! The SMILE Project (Size Matters: Innovative Length Estimates) is helping to revolutionize how fish length data is collected. By combining citizen science with innovative camera and laser technology, we're making it easier to gather the critical data needed for sustainable fishery management.

Thanks to support from NOAA’s Coral Reef Conservation Program, SMILE is empowering recreational divers and snorkelers to contribute vital length measurements in the Florida Keys and South Atlantic region—without the need to handle fish directly.

SMILE Partners:

  • REEF Environmental Education Foundation
  • SAFMC Citizen Science Program
  • Scripps Institution of Oceanography (Semmens Lab)
  • SECOORA
  • Axiom Data Science
  • UCSD Engineers for Exploration (E4E)

Through affordable, diver-friendly equipment and community-driven data collection, SMILE is creating a new path for fisheries stock assessments and ecosystem-based management.

About the SMILE Project

Citizen science programs like REEF's Volunteer Fish Survey Project (VFSP) and the SMILE project empower the public to generate vital monitoring data and actively participate in resource management. Divers and snorkelers play a unique role by reporting marine ecosystem findings, becoming the eyes of scientists beneath the surface.

The SMILE project leverages affordable, easy-to-use FishSense Lite camera technology developed by engineers at the University of California San Diego's Engineers for Exploration program and Semmens Lab at Scripps Institution of Oceanography.

A stakeholder panel provides guidance on survey methods, species of interest, and image collection locations. All video, images, and fish abundance and length data will be publicly available to support current research, fisheries management, and future machine learning advancements.


Field Testing & Project Goals

We are field testing the camera system and survey methodology in the Florida Keys, during REEF Field Survey Trips, and the Grouper Moon Project. Economically important species such as groupers, snappers, hogfish, and ecologically vital parrotfish are being measured.

Supported by NOAA's Coral Reef Conservation Program, this collaboration among REEF, SAFMC's Citizen Science Program, SECOORA, Scripps Oceanography, UCSD, and Axiom Data Science will introduce new data into fisheries stock assessments and strengthen communication with the dive community about conservation.


How Can You Help?

Take Our Survey – No Experience Required!

Your feedback is critical to shaping the SMILE project. The survey takes less than 15 minutes and helps us better understand divers' interests, fish ID skills, and what motivates (or prevents) participation in marine science.

Complete the survey and you'll be entered into a raffle to win a REEF shirt of your choice!

DIVE INTO THE SURVEY NOW


Join Us on Research Dives in 2025

Help field test the cameras and protocols during SMILE dives in the Florida Keys—FREE for qualified participants thanks to grant support. Advanced Open Water divers with at least 50 dives are welcome to join.

Upcoming Dives


  • Roatan Field Survey Trip – June 2025

SMILE cameras will also be available during REEF's 2025 Field Trips.
