Summary The study presents a first report on the validation of otolith increment in the golden‐spotted rabbitfish Siganus guttatus . The formation of daily sagittal growth increments in S. guttatus was validated using hatchery‐reared larvae and juveniles collected from day of hatching to day 35. Mean increments were 5.6, 13.1, 24.5 and 34.8 for the 7, 15, 25 and 35 day‐old fish, respectively. The results demonstrated that sagittal increments were formed daily and thus can be used to determine the age in days of the species.
