Abstract:

Diet analyses of demersal reef fishes (n= 2,351) collected in the north central Gulf of Mexico between March 2015 and December 2015. We performed visual gut content identification for all identifiable prey and DNA barcoding for unidentifiable (i.e., degraded, highly digested) fish prey. Genetic analysis of unidentified prey was conducted from December 2015- December 2016.
