The authors of this study (including REEF staff Lad Akins) examined the recent case of Indo-Pacific lionfish invading Northern Gulf of Mexico coastal waters. The authors compared traditional reef fish monitoring efforts to less traditional data including the observations of divers through REEF's Volunteer Fish Survey Project and spearfishers. They found that citizen observations documented lionfish 1-2 years earlier and more frequently than the more traditional monitoring efforts.
This paper provides an updated look at non-native marine fishes that have been reported from Florida waters, following up on two previous papers (Semmens et al 2004 and Schofield et al 2009). The paper, co-authored by staff from REEF and the US Geological Survey (USGS), also provides information on Early-detection/Rapid-response (ED/ER) efforts.
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.
