The investigators examined the interactions between invasive lionfish and native Nassau grouper using both a manipulative field study and a controlled lab experiment. This dataset, resulting from the field study, contains growth rates of juvenile lionfish (20-140 mm) on reefs with controlled abundances of native Nassau grouper.

During the summer of 2010, the investigators manipulated the abundance of Nassau grouper on 28 near-shore patch reefs and measured the growth and survival of juvenile (20-140 mm) lionfish. They also censused the community of small reef fishes (< 50 mm) to look for evidence of indirect effects that grouper might have mediated through lionfish.

Locations of coral reef survey dives and sightings, or collections of the invasive red lionfish, Pterois volitans, near Lee Stocking Island, Bahamas for the projects "Ecological Release and Resistance at Sea: Invasion of Atlantic Coral Reefs by Pacific Lionfish" and "Mechanisms and Consequences of Fish Biodiversity Loss on Atlantic Coral Reefs Caused by Invasive Pacific Lionfish" (NSF OCE-0851162 & OCE-1233027). All dives were made from various small vessels (17' to 24' l.o.a., 40 to 275 HP outboard motors, 1 to 7 GRT). Vessel names include, Sampson, Orca, Potcake, Lusca, Lucaya, Zardoz, Parker, and Nuwanda.
