Abstract: We aim to understand ontogenetic shifts in habitat use and feeding patterns by 2 fish species, Lutjanus fulviflamma and L. ehrenbergii, within a tropical seascape in East Africa. Stomach contents and stable isotope signatures of muscle tissues (δ 13 C and δ 15

“…Many juveniles of these species feed mainly on small crustaceans until they reach a certain body size, at which their foraging abilities and nutrient requirements change (Nakamura et al 2003;Kamukuru and Mgaya 2004). The lethrinids and lutjanids utilize shallow seagrass/mangrove canopies as nurseries or feeding grounds in many Indo-Pacific regions (Unsworth et al 2008b(Unsworth et al , 2009Kimirei et al 2011;Nakamura et al 2010Nakamura et al , 2012Berkström et al 2013). We found their densities to increase at the intertidal stations during flood tides, especially at W. Previous researchers have found that some decapods move into shallow areas during flood tides, and some carnivorous fish may follow them at these times for foraging (Klumpp and Nichols 1983).…”

“…In addition, DNA barcoding has been used to identify seagrass species in the gut of a marine herbivorous fish and in sediments (Chelsky et al, 2011;Lucas et al, 2012;Mazzuca et al, 2013;Osathanunkul et al, 2015a,b;Hamaguchi et al, 2018). Genetic barcoding has only been used to correct fish species identification in the mangroveseagrass-coral reef continuum (Berkström et al, 2013) and to reveal the species composition of parrotfish juveniles in the seagrass beds of the Ryukyu Islands, Southern Japan (Ogawa et al, 2015). The application of the DNA barcoding technique to identify eggs of fish and invertebrates in wetland ecosystems, especially on the leaves of the seagrasses, has not been reported.…”
