摘要

Cardinalfishes(family Apogonidae)form a major component of nocturnal planktivore assemblages on coral reefs. In order to assess their trophic role on reefs, we examined diet, diet feed- ing behaviour and nocturnal foraging in 7 species in the lagoon at One Tree Reef, Great Barrier Reef, Australia. Between 64 and 93/100 of fish collected at dawn had identifiable material in the stomach compared with 5 to 36/100 of fish collected at dusk, suggesting that all 7 species were predominantly nocturnal feeders. The movement of apogonids between resting sites and feeding grounds was examined using day and night visual surveys.
