摘　　要：利用黄鮟鱇Lophius litulon耳石对2007年3月~2009年5月取自东海北部、黄海南部黄鮟鱇的年龄和生长特征进行了分析。结果显示,黄鱼安鱼康群体由1~5龄组成,以1~2龄鱼为主,捕捞群体呈低龄化;生长特点属均匀生长型,体重与体长关系为W=1.55897×10-5L3.10865,体长与耳石半径关系为L=244.11R-210.6,体长生长方程为Lt=749.9[1-e-0.349（t＋0.256）],体重生长方程为Wt=13496.4[1-e-0.349（t＋0.256）]3.10865,极限年龄Tmax为8.337龄,生长拐点年龄ti为2.994龄,此时对应的体长和体重分别为508.8mm和4038.7g。为保护黄鮟鱇资源,应限捕体长在500mm以下的个体。Based on the otoliths,the age and growth characteristics of Lophius litulon in north of the East China Sea and south of the Yellow Sea during March,2007 ~ May,2009 were studied.The results showed that the age of captured L.litulon was between 1 ~ 5 a,and were mainly composed of young fishes of 1~2 years old.The relationship between body length（L）and weight（W）was described as W=1.558 97×10-5L3.108 65.The relationship between the radius of otolith and body length was L=244.1R-210.6.The growth pattern can be described by von Bertalanffy equation as Lt=749.9[1-e-0.349（t＋0.256）],Wt=13 496.4[1-e-0.349（t＋0.256）]3.108 65.The maximum age was 8.337 a.The age of growth turning point was 2.994 a,and the corresponding body length and body weight were 508.8 mm and 4 038.7 g respectively.For the purpose of resource conservation,fishing of L.litulon should be limited to the individuals with body length below 500 mm.
