Putting It to Work: New Publication From the Grouper Moon Project

Parallel mounted lasers projected on the side of a Nassau grouper at the Little Cayman spawning aggregation.

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. Analysis of seven years of data show that length-distribution data can be collected by divers using a video-based system with parallel lasers calibrated to a specific distance apart. This novel technique is one of just several being conducted as part of the Grouper Moon Project. View the paper online here.
