The purpose of this study was to determine the size stucture, growth pattern, and relative conditions of rabbitfish (Siganus canaliculatus). Sampling was randomly done from the catches of fishermen in fesh condition. The number of fish samples taken for analysis was 61 individuals. Their fin color was yellowish or sometimes reddish purple. Measurements found that the fish samples had length range of 127 mm - 270 mm, and weight range of 21 and 249 g. Males had size range of 131-270 mm long with a body weight of 26-249 g and females had a body length of 127-249 mm, with a weight range of 21-191 g.
Key words: Factor conditions, catches, fishermen, measurements.
