摘要

本報告以脊椎骨輪紋判讀法查定印度洋產長鰭鮪之年齡與成長關係，結果顯示如下：(1)尾叉長與脊椎骨椎徑長之直線廻歸關係，在雌雄魚間無顯著差異存在；(2)對數値之體重與對數値之尾叉長之直線廻歸關係，在雌雄魚間亦無顯著差異存在；(3)輪紋一年形成一輪，輪紋形成期從九月至十二月；及(4)估得之von Bertalanffy體長及體重成長方程式分別爲：l(下标 t)＝163.71(1-e(上标 -0.1019(t+2.0668)))及W(下标 t)=81.70(1-e(上标 -0.1019(t+2.0668)))^(2.8758)

Using the vertebra ring reading method,this paper assesses the age andgrowth of albacore(Thunnus alalunga)in the Indian Ocean.The resultsindicate that(1)the comparison of regression formulae for fork length vs.centrum radius between males and females showed no significant difference;(2)the comparison of regression formulae for logarithm body weight vs.logarithm fork length between males and females showed no significantdifference;(3)one annulus was formed per year,the ring formation periodbeing from September to December;and(4)the von Bertalanffy's growthequation for fork length and body weight were estimated as follows:l(subscript t)=163.71(1-e(superscript -0.1019(t+2.0668)))andW(subscript t)= 81.70(1-e(superscript -0.1019(t+2.0668)))^(2.8758)
