Relationships between otolith morphometrics and fish body size of the spiny siganid (Siganus spinus Linnaeus 1758) caught from Lagonoy Gulf, Philippines were determined from wild-caught pre-settlement juveniles. Thirty individuals with 29.2-33.3 mm standard length were examined and their raw sagittae were extracted and measured. Sagittal width can be estimated from standard length (R2= 0.68). Relationships between otolith length and total weight were low with coefficient of determination (R2) of 0.17. Moderate relationships were found between otolith length and total length (R2= 0.28) and otolith length and standard length (R2=0.35). Regression between the aspect ratio of the caudal fin and otolith length (R2= 0.25) suggests that the balance function of the otolith may reveal in the fin.
