Shoreline shapefiles
were gathered from the Global Administrative Area database
(http://www.gadm.org/). Based on ecosystem services provided
(Duarte, 2000; Cullen-Unsworth et al., 2014) seagrass meadows are
recognized as priority habitats for conservation. A number of
studies reported on the negative effects of fish cage deposition on
seagrass meadows (e.g. Rountos et al., 2012).
