Fish Population Fluctuation Estimates Based on Fifteen Years of REEF Volunteer Diver Data For the Monterey Peninsula, California

A database of fish surveys conducted by volunteer recreational divers trained by REEF was used to examine fish populations in Monterey Peninsula, California, between 1997 and 2011. Over 3,000 surveys were conducted as part of this ongoing citizen science effort. The analysis was conducted using a numerical conversion method to calculate population estimates from REEF log-scale data (this method was described in a companion paper published in the same CalCOFI Reports issue).

Estimating Fish Populations From REEF Citizen Science Volunteer Diver Order-of-Magnitude Surveys

This paper describes several models to convert order-of-magnitude count data that are collected during REEF Roving Diver Technique (RDT) surveys to a numeric mean, and demonstrate that with a sufficient number of surveys, estimates of the mean with a reasonably small confidence interval can be attained. For each model, parameter estimates and associated confidence intervals were derived from 292 RDT surveys where precise counts were also made. Models were compared using the small sample Akaike Information Criteria (AICc).

REEF Fest: Celebrating 20 Years of Marine Conservation Success

In the summer of 1993, the first REEF fish surveys were conducted by a group of pioneering volunteers. Twenty years later, the Volunteer Survey Project and other REEF initiatives are leading the way as innovative and effective marine conservation programs. To celebrate, we are hosting 4 days of diving, learning, and parties this August in Key Largo, Florida. We hope you will join us!
