Little Cayman Fieldwork

Below are photos that I took during the aforementioned field season.

In February 2012, I traveled to the Cayman Islands to assist my committee member Dr. Brice Semmens and his research team with monitoring a Nassau grouper (Epinephelus striatus) spawning aggregation off the west end of Little Cayman. This work was a component of the Grouper Moon Project, a collaborative research effort between REEF and the Cayman Island Department of the Environment. During day time dives I assisted with fish counts in order to get an estimate of the aggregation size during the 2012 breeding season and helped track the proportion of fish in each color morph as the breeding season progressed. Nassau grouper have 4 color morphs - white belly, bicolor, barred and dark. The field work was featured in the PBS series "Changing Seas". I was included as a scientific expert in Episode 403 - Grouper Moon, briefly discussing genetic connectivity of the species in the Caribbean Sea.
