The lionfish team zipped up their 5mm wetsuits, donned their hoods, and braved the dropping water temperatures to conduct the 5th year of reef monitoring. It is well known that the presence of lionfish negatively affects the abundance and recruitment of fish on reefs, however, the secondary and long-term effects to is yet to be fully understood. It is the goal of these surveys to provide a data set that can answer these questions.Big Eye fish sighted again!

The team surveyed fish size and abundance at the 16 study reefs. They were excited to see the Big Eye fish again some three months after its initial sighting at the same site and exact same coral head. Additionally, the divers were armed with cameras and rugosity chains to assess the reefs benthic cover and complexity. We were pleased to see the reefs that were bleaching in September had started to recover. Less pleasing to see were the high densities of lionfish at the non-removal sites; one site had 20 lionfish in an area the size of a dining table!

These surveys contribute to one of the longest monitoring data sets that examine the effects of lionfish on reefs.  Dr. Curtis-Quick along with collaborators Dr. Green, Dr. Cote and Lad Akins will be working up this data for a publication later in 2015.  This monitoring is hoped to be continued in years to come and we wish to thank all the interns and volunteers who have assisted with the monitoring over the last five years. Special thanks to Alicia Hendrix, the current Research Assistant, who over the last year has made huge contributions to the lionfish team’s work.
