Description

A field experiment was conducted on artificial patch reefs to test for the effect of lionfish (Pterois volitans) density on native fish abundance, diversity, and community structure. This dataset includes counts of native fish species observed on reefs where lionfish density was controlled.

Methods & Sampling

Dataset acquisition description

The experiment was conducted near Lee Stocking Island, Bahamas from June to August 2011. The expermint used 10 reefs which were manipulated so that 4 reefs had 0 lionfish on them (controls), and 6 each had a unique density of lionfish (1, 2, 4, 8, 10, or 12). These numbers represent the weighted average weekly lionfish densities (number of lionfish per meter squared) on each reef throughout the whole experiment. Complete censuses of the native fish population on each reef were conducted weekly for 6-weeks during the summer recruitment season.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes:
- Modified parameter names to conform with BCO-DMO naming conventions.
- Replaced blanks with 0 in the count columns; replaced blanks with 'nd' ('no data') in all other columns.
- Added lat and lon of the site from the metadata provided.
- Transposed size bins to rows in lowest level of data.
- 09-Jan-2018: removed embargo on dataset.
