Unique specimen "IDNumber" for over 750 specimens of Hawaiian grouper (hapu'upu'u, Hyporthodus quernus; family Epinephelidae) are included in this dataset. Each specimen has the following information associated with it: standard body length, body weight, and gonad weight metrics, date of collection, and both macroscopic & microscopic sexual identities and sexual maturation states (the latter based on E.
