Description

Results are reported from a manipulative field experiment examining the effect of lionfish predation on bridled goby population density. Experiments were conducted in 2011 at reefs near Lee Stocking Island, Bahamas.

Methods & Sampling

Investigators studied the effects of lionfish predation on bridled goby populations through a manipulative field experiment. The density of bridled goby on 24 near-shore patch reefs was manipulated. Over a 30 day experimental period bridled goby mortality was monitored among four treatments: no-predator control, lionfish only, graysby grouper (native predator) only, and lionfish + graysby grouper.

Data Processing Description

BCO-DMO Processing Notes:
- Modified parameter names to conform with BCO-DMO naming conventions.
- Added lat and lon for the reef site from the metadata provided.
- Replaced blanks with 'nd' ('no data'; measurements not made due to Hurricane Irene.)
- Added 'treatment' column containing the treatment definition.
- 09-Jan-2017: removed embargo on dataset.
