We are saddened to share news about the passing of one of our most active REEF members, Mike Phelan, earlier this month in Jupiter, FL. Mike's enthusiasm for fishcounting was infectious and he often taught fish ID. He had participated in many REEF projects and was a member of our Advanced Assessment Team. REEF co-founder, Paul Humann, remembers Mike’s unsurpassed passion for marine life and conservation. "REEF's database is much more meaningful thanks to Mike's contribution of nearly 1,500 fish surveys over the last 14 years.

Over the past decade, Indo-Pacific lionfishes have invaded and spread throughout much of the tropical and subtropical northwestern Atlantic Ocean and Caribbean Sea. These species are generalist predators of fishes and invertebrates with the potential to disrupt the ecology of the invaded range. Lionfishes have been present in low numbers along the east coast of Florida since the 1980s, but were not reported in the Florida Keys until 2009.

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.
