Participate in the
Great Annual Fish Count

6 Great Reasons to Participate in the GAFC:

  1. Find something more to do on your dives than just looking at pretty fish.
  2. Make a difference and become a citizen scientist
  3. Learn to identify and document fish diversity
  4. Raise awareness about marine habitats and trends in fish populations
  5. Provide valuable data to researchers as they monitor ocean changes
  6. Try your hand at doing a REEF fish survey

Who can participate in the GAFC?

Anyone can join in the fun, whether you're a diver or a snorkeler.

How do I participate in the GAFC?

Check out the calendar of this year's scheduled events. Join in a free fish ID class near you, then hop in the water (it's even better with friends!) and conduct a survey of the fish you see.

Don't see an event scheduled near you?

Ask your dive club or shop if you can help organize one, or create your own, big or small. See our Organize an Event page for details.

How to get in on the GAFC fun

First, join REEF (membership is free!)

Conduct fish surveys and join leagues of citizen scientists around the world.

Do I have to be an expert to help?

No. The GAFC and the year-round Volunteer Fish Survey Project by REEF uses an easy to learn, fun survey method. Basic fish identification skills are all that are needed. Attending a fish ID class or listening to some of our online Fishinars will give you a great start, and you'll get even better as you do more.

View our current online Fishinars as well as access our past Fishinars, and start learning how to identify fish in your area!
