本研究主要以臺灣北部海域產大棘大眼鯛 ( Priacanthus macracanthus )利用中翼 骨進行年齡成長之研究。採樣期間自2015年1月至2017年7月，總計採集1784尾樣本 ，尾叉長 (FL) 介於3.4 - 31.4 cm，平均尾叉長為23.3 ± 2.2 cm。利用中翼骨判 讀輪紋所得平均年齡為3.3 ± 0.8歲。中翼骨經處理後成功進行輪紋判讀共724個 ，中翼骨輪紋數(MRs)與尾叉長(FL)之迴歸關係經共變異分析(ANCOVA)檢定雌雄間並 無顯著差異( P< 0.05)，故將雌雄合併表示關係式為：MRs = 0.0826 × FL^0.826(r ^2= 0.845，n = 724)。以中翼骨輪紋數換算之年齡與尾叉長估算von Bertalanffy 成長參數，雌雄魚之間無顯著差異( P< 0.05) ，成長參數：L ∞= 323.7 mm，k = 0.294/yr，t0 = -0.699。

The red bigeye ( Priacanthus macracanthus ) is commercial fishery targeted demersal species which lives in the surrounding waters of Taiwan, with depth rager of 20 to 400 m. Age and growth of the red bigeye which caught by longline fishery off northern Taiwan waters. From Jan. to Jul. 2017, totally 1784 red bigeye were caught per month sampling, and the fork length (FL, 6.9 ~ 31.4 cm) and body weight (BW, 5.0 ~ 514.7 g) were measured. The relationship formula of Mesopterygoid and folk length was MRs = 0.0826 × FL^0.826(r^2= 0.845，n = 724). The von Bertalanffy growth curve parameters obtained: L ∞= 323.7 mm，k = 0.294/yr，t0 = - 0.699.
