RESUMEN. Se obtuvieron estómagos de ejemplares adultos deAnisotremus interruptus y Lutjanus argentiventris para conocer los componentes alimentarios de cada especie y sus interacciones tróficas durante un periodo de surgencia en el Pacífico Central Mexicano. Se identificaron 79 tipos de presas agrupadas en 15 categorías alimentarias. La dieta de A. interruptus está constituida principalmente de microinvertebrados (anfípodos y larvas de crustáceos), holotúridos y ofiuros. L. argentiventris se alimenta de macroinvertebrados (camarones, cangrejos y estomatópodos), peces y cefalópodos. Ambas especies presentan una estrategia alimentaria generalista y una superposición trófica baja. La dieta de estas especies está relacionada con la apertura de la boca.

Food habits and trophic interactions of Anisotremus interruptus (Pisces: Haemulidae)and Lutjanus argentiventris (Pisces: Lutjanidae) in the Central Mexican Pacific ABSTRACT. Stomachs of adults of Anisotremus interruptus and Lutjanus argentiventris adults were collected to analyze the prey items of each species and trophic interactions during an upwelling season in the central Mexican Pacific. We identified 79 prey items grouped into 15 food categories. The diet of A. interruptus consists mainly of micro invertebrates (amphipods and crustacean larvae), holothurians and ophiuroids. L argentiventris feeds on macro invertebrates (shrimps, crabs and stomatopods), fish and cephalopods. Both species have a generalist feeding strategy and low dietary overlap. The diet of these species is related to the mouth shape opening.
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.
