Growth rate, longevity, and maturity were estimated for four commonly targeted species of surgeonfish in Hawai‘i: ringtail surgeonfish/pualu Acanthurus blochii, eyestripe surgeonfish/palani Acanthurus dussumieri, orange-band surgeonfish/na‘ena‘e Acanthurus olivaceus, and yellowfin surgeonfish/pualu Acanthurus xanthopterus. All species demonstrated rapid growth with long life spans. The maximum observed ages were 26 years for A. blochii, 30 years for A. dussumieri, 14 years for A. olivaceus, and 29 years for A. xanthopterus. Females reached maturity at a greater size and age for all four species. All species reached maturity within the first 3 years of life and approximately 59–67% of maximum size. All four surgeonfish species demonstrated a biphasic mortality schedule with a higher total mortality rate occurring earlier part of life. This study provides a comprehensive study of the age, growth, and maturity for four large-bodied surgeonfish species which are commonly targeted throughout Hawai‘i and the rest of the Indo-Pacific.

估计了夏威夷四种常见目标刺尾鱼的生长速度、寿命和成熟度：环尾刺尾刺尾鱼/pualu Acanthurus blochii、眼纹刺尾刺尾鱼/palani Acanthurus dussumieri、橙带刺尾刺尾鱼/na'ena'e Acanthurus olivaceus和黄鳍金枪鱼刺尾鱼/pualu Acanthurus xanthopterus。所有物种都表现出快速增长和长寿命。A. blochii的最大观察年龄为 26 岁，A. dussumieri为 30 岁， A. olivaceus为 14 岁， A. xanthopterus为 29 岁. 所有四个物种的雌性都在更大的尺寸和年龄下达到成熟。所有物种都在生命的前 3 年内达到成熟，大约为最大尺寸的 59-67%。所有四种刺尾鱼物种都表现出双相死亡率时间表，总死亡率较高，发生在生命的早期。本研究全面研究了夏威夷和印度-太平洋其他地区常见的四种大型刺尾鱼的年龄、生长和成熟度。
