Age determination and growth of Pacific bluefin tuna, Thunnus orientalis, off Japan and Taiwan
Age determination of wild captured Pacific bluefin tuna, Thunnus orientalis, was conducted using sagittal otoliths of 806 specimens (47–260 cm in fork length) caught in the waters off Japan and Taiwan. Otoliths were transversely sectioned and the opaque and translucent zones were analyzed. Opaque zo...

| description | Age determination of wild captured Pacific bluefin tuna,
Thunnus orientalis, was conducted using sagittal otoliths of 806 specimens (47–260
cm in fork length) caught in the waters off Japan and Taiwan. Otoliths were transversely sectioned and the opaque and translucent zones were analyzed. Opaque zones mainly appeared on the otolith edge from April to July, indicating that the opaque zone is formed annually. The opaque zones formed during later life (age 10+) were more distinct than the earlier zones. The estimated ages of specimens ranged from 1 to 26 years. Parameters of the von Bertalanffy growth function were estimated to be 249.6
cm, 0.173, and −0.254 years for
L
∞
,
k, and
t
0, respectively. Growth of younger fish was rapid up to 5 years old attaining about 150
cm, and then growth rate decreased. After that, fish attained about 200
cm at 9 years old and about 225
cm (90% of
L
∞
) at 13 years old (50% of maximum age). This paper updates the biological information on length at age with a large size range to support stock assessment model analyses for this commercially valuable species. |
