This paper presents a key technique that scientists from REEF and our Grouper Moon collaborators have used to monitor fish on the Little Cayman spawning aggregation that does not require the capture and handling of fish. We show that length-distribution data can be collected by divers using a video-based system with parallel lasers calibrated to a specific distance apart, and subsequently use those data to monitor changes in the size distribution over time.

A new paper was just published in the scientific journal Biological Conservation documenting a key monitoring technique established by scientists from REEF and our Grouper Moon collaborators. The paper, "Documenting recovery of a spawning aggregation through size frequency analysis from underwater laser calipers measurements", describes a technique to monitor changes in fish size on the Little Cayman spawning aggregation through time that does not require the capture and handling of fish.

The 21st annual Great Annual Fish Count (GAFC) took place in July, with many dive shops, dive clubs, and other groups organizing fish ID classes, dive /snorkel days, BBQs and more fun gatherings. The concept behind the GAFC is not only to accumulate large numbers of surveys during the month of July, but to introduce divers/snorkelers to fishwatching and get them started doing REEF surveys. Groups from California, Oregon, Washington, British Columbia, Hawaii, Massachusetts, Maine, Hawaii, Florida, North Carolina, and new to the event in 2012 - New Brunswick, all participated!
