Data from: The influence of Sargassum biomass and thallus density on the recruitment of coral reef fishes

Background (extract from related publication): 

A habitat’s structural complexity is a key determinant of the recruitment and composition of associated communities. While the influence of the physical structure of corals on coral reef fish recruitment is well studied, the significance of other benthic components, like macroalgae, remains unclear. We used experimental patches of the canopy-forming macroalga Sargassum to assess the influence of macroalgal complexity, which was manipulated by altering thallus density and biomass, on coral reef fish recruitment. 

Methods (extract from related publication):

We established twenty-five 75 x 75 cm patches on the reef flat of Orpheus Island, (inshore, central Great Barrier Reef) during austral summer. Patches were randomly divided into five treatments of varying Sargassum thallus density (3-9 thalli) and/or biomass (177-779 g per patch) and surveyed daily for recruiting fishes for 18 days. 

This data record contains:

  • 1 MS Excel file (.csv) containing fish size data
  • 1 MS Excel file (.csv) containing sargassum size data
  • Link to GitHub repository with statistical analysis codes 

MS Excel worksheets have also been saved and archived in OpenDocument (.ods) format.
