REEF's Citizen Science Saturday program for July is a Fish Identification Class and Dive organized in honor of the Great Annual Fish Count!

The Great Annual Fish Count (GAFC) is an initiative designed to encourage the public to become engaged with marine citizen science. Every July, divers and snorkelers join in the GAFC to learn about marine life and conduct fish surveys as a part of REEF’s ongoing Volunteer Fish Survey Project. Sightings reported by volunteer divers and snorkelers provide valuable data to researchers monitoring ocean changes. Volunteers conducting REEF surveys have discovered new species, helped establish the known range of certain species, tracked the spread of invasive species, and tracked fish populations over time. Join us to take part in this engaging and powerful ocean citizen science project!

REEF divers and snorkelers use an easy, visual survey method specifically designed for volunteer data collection. Each recorded species is assigned an abundance category based on how many of each species were seen during the survey. Survey materials including a slate, pencil, underwater paper and laminated photo identification cards will be provided for participants to use during the program. If you have your own camera, we encourage you to bring it to take pictures of mystery fish.

This program is open to divers and snorkelers. The day will begin with a classroom lesson including fish identification and an introduction to REEF's survey method. In the afternoon, we will head out on the water for an afternoon dive/snorkel trip to two shallow reef sites, where we will conduct REEF surveys.
