NCCOS-supported research found that commercially important fish, such as snappers and groupers, off southwest Puerto Rico are more abundant at mesophotic depths (60 -80 meters) than shallow depths (30 meters or less). The study, published in the journal Coral Reefs , suggests that mesophotic coral ecosystems serve as a refuge for heavily exploited, shallow-water reef species and are important for their conservation. Most species present at mesophotic depths off La Parguera, Puerto Rico (76 percent of 103 species) were common inhabitants of shallow reefs, indicating that connectivity does occur between shallow and mesophotic reefs.
The study is part of NCCOS'sDeep Coral Reef Ecosystem Studies program, which seeks to betterunderstand the mesophotic coral ecosystems off La Parguera, Puerto Rico, including characterizing their community composition and structure, determining their potential connectivity, and assessing their vulnerability to anthropogenic stresses.
