In this study we examined the extent of direct disturbance by reef sharks on the grazing rates of herbivorous fishes. The data analysed in this study were based on standardised video camera (GoPro) deployments at 19 sites across the northern Great Barrier Reef, Australia. At each site there were 8-10 replicate video deployments, with all sampling conducted in the shallow (~2 m) reef crest/edge habitat during January/February 2021/2022. All video deployments were set to film a 1 m2 area of reef, predominantly covered in algal turfs. Videos were initially examined for any sharks that passed over the 1 m2 area. For videos where shark passes were recorded, the species identity, size, and number of bites taken by nominally herbivorous fishes were recorded in 5-minute observation periods immediately before as well as immediately after the shark passed. In addition, herbivorous fish species identity, size, and bite rate were quantified in two forms of control treatments, based on randomly selected 5-minute observation periods. The CSV file contains data on nominally herbivorous fish feeding (including species identity, size, number of bites, and biomass standardised number of bites) during the 5-minute observation periods, as well as data on when the shark entered and exited the quadrat, and when fish feeding started/ended during the observation periods.
