Description

This dataset contains results from experiments conducted in the Bahamas and the Cayman Islands. Experiments examined whether or not invasive lionfish (Pterois volitans) ate cleaner gobies of the genus Elacatinus. Data include the number of gobies eaten, the number of strikes made against the goby and the time it took to strike, and the time passed before predation occurred.

Methods & Sampling

The investigator conducted laboratory experiments in the Bahamas and the Cayman Islands to determine whether or not lionfish, Pterois volitans (PTVO), eat cleaner gobies, Elacatinus genie (ELGE), and whether or not a lionfish eating a cleaner goby affected the odds of the same lionfish subsequently eating a non-cleaner goby, Coryphopterus glaucofraenum (COGL). The same experiment was conducted with two ecologically similar native predators, the coney grouper, Cephalopholis fulva (CEFU), and the graysby grouper, Cephalopholis cruentata (CECR).

Experiments at Lee Stocking Island took place at the Lobster Lab at the Perry Institute of Marine Science. Experiments at the Cayman Islands took place at the Wet Lab at the Central Caribbean Marine Institute. Experiments tooks place from 22 June 2011 to 23 August 2011.

Data Processing Description

BCO-DMO Processing Notes:
- Modified parameter names to conform with BCO-DMO naming conventions.
- Added lat and lon from the metadata provided.
- Replaced blanks, 'info not available' and 'n/a' with 'nd' ('no data')
- Separated 'Goby species & ID' column into separate columns for species code and id.
