Gag (Mycteroperca microlepis) space-use correlations with landscape structure and environmental conditions

To explore variation in space use under different environmental conditions, we acoustically tagged gag (Mycteroperca microlepis) established on experimental artificial reefs in the Gulf of Mexico and used an acoustic positioning array to record animal positions during the winters of 2007 and 2008. From side-scan sonar imagery, we created a categorical habitat map of the hard- and sand-bottom habitats surrounding the reef. We recorded water …
