Periophthalmodon septemradiatus (Hamilton, 1822) is a mudskipper of the Mekong Delta. It can be found along estuaries and lower reaches of rivers. We determined diet and feeding ecology of this species by analyzing the contents within the stomachs of 1360 fish samples collected from August 2017 to July 2018. Data analysis suggests that P. septemradiatus is a carnivorous fish. We found six main food item categories: small fish, prawns (Acetes spp.), crabs (Uca spp.), mollusks, ants (Dolichoderus sp.), and detritus. Both males and females at different sizes, seasons, and habitats ingest primarily Dolichoderus sp., secondarily detritus, and rarely other prey. Diet composition is similar between sexes but varies according to fish size, season, and habitat. Dolichoderus sp. and detritus regulate the spatial variation of food composition. Our findings contribute to future artificial cultivation for conservation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
