REEF Volunteer Fish Survey Project

This morning on the Grouper Moon Project Livestream, Dr. Christy Pattengill-Semmens mentioned how you can get involved with Reef Environmental Education Foundation’s volunteer fish surveys. Here is some more information so that you can get involved in this exciting citizen science project.What is the REEF Volunteer Fish Survey Project?

Reef Environmental Education Foundation (REEF) protects marine life through education, service, and research. REEF facilitates programs that actively engage divers, snorkelers, and other marine enthusiasts in marine conservation. This is primarily accomplished through the Volunteer Fish Survey Project. Since its launch in 1993, this citizen science program has generated one of the largest marine life databases in the world. In 2020, the database surpassed 250,000 surveys conducted at almost 15,000 sites throughout the world’s oceans by over 16,000 volunteer divers and snorkelers worldwide.

With knowledge, training, and the opportunity to get involved, these marine citizen scientists make significant and ongoing contributions. REEF provides varied training opportunities to encourage wide participation, and has a comprehensive experience-rating system and QA/QC checks for data submission to ensure high quality data. The survey methodology was developed with support from The Nature Conservancy (TNC) and guidance by the Southeast Fisheries Science Center of the National Marine Fisheries Service (NMFS).

The project allows volunteer SCUBA divers and snorkelers to collect and report information on marine fish populations as well as selected invertebrate and algae species in temperate areas. To find out more about the REEF Invertebrate & Algae Monitoring Program, click here. The data are collected using a fun and easy standardized method, and are housed in a publicly-accessible database on REEF’s Website. These data are used by a variety of resource agencies and researchers.

How do I participate?

Anyone, anywhere can participate in the Volunteer Fish Survey Project. REEF volunteers use the Roving Diver Technique (RDT), a visual survey method specifically designed for volunteer data (see below). The only materials needed are an underwater slate and pencil, a good reference book, and access to the internet to submit the data online. REEF has developed several survey materials that make things easy, including pre-formated underwater paper and waterproof ID guides. These supplies, as well as slates, pencils, and training courses are available through REEF’s Online Store.

Check out the VFSP Survey Toolbox for a complete list of resources available to REEF surveyors in each of our ten regions.

Can I collect data while snorkeling or freediving?

Snorkelers and freedivers are valuable assets and can also conduct surveys. You do not have to be a scuba diver to conduct REEF surveys and collect important data.

If snorkeling is your thing, you can view much more information on doing surveys while snorkeling here.

If you’re into freediving, we’ve got some vital info and handy surveying tips for you here.Submitting your data

Following the dive, each surveyor transfers the information about their survey dive, including survey time, depth, temperature, and other environmental information, along with the species sightings data, to the REEF database. A separate survey submission is done for each dive.

Information is submitted one of two ways:

The location of the survey is recorded using the common dive site name and the REEF Geographic Zone Code. The Zone Codes are a hierarchical list of codes.

Nassau grouper fish counts!

Yesterday the researchers tagged 150 Nassau grouper using a special tag called a Floy Tag. Each tag has a unique number on it and a colorful visible green tag that our team of divers can easily see underwater.Today I did a fish count survey which is used by the scientists to estimate the population of Nassau grouper. For a fish count survey, I had a clipboard with a piece of underwater paper to record the data.

To complete the survey, I swam alongside the group of Nassau grouper that were up in the water column. I counted each Nassau grouper that I saw, counting up to 50.  I would record any tagged fish that I saw  within the group of 50. I counted a total of 7 groups of 50 fish and counted only 2 tagged fish. This means that there are much more fish at the SPAG than we estimated since we didn’t see many of the 150 fish that we had tagged just yesterday! It left us wondering, where are our tagged fish friends that we saw just yesterday. What do you think? Post where you think the fish might be in the comments.
