The Cape stumpnose Rhabdosargus holubi is one of the most abundant marine fish species found in estuaries along the south-east coast and depends on estuaries as exclusive nursery habitats. This study aimed to identify the epiphytic diatom and macrofauna food resources available to R. holubi in the seagrass Zostera capensis habitat of the Swartkops Estuary. This habitat has been identified as a core nursery area for this species through a combination of greater abundance, higher growth and survival of juveniles. This study compared what was found in the seagrass habitat and assessed whether this habitat provided for the prey resources most commonly observed in the diet of R. holub.enFood availabilityJuvenile marine fishNursery areaDiatomsInvertebratesUniversity of the Western Cape
