英文摘要	利用2004年2月--2005年3月在闽南近海逐月采集的中国团扇鳐(PlATyrHInA SInEnSIS)样品,以脊椎骨为材料,采用硝酸钴染色方法,研究其年龄结构与生长特性。研究结果表明,中国团扇鳐脊椎骨上的年轮结构多数为单带型、少数为双带型和多带型;年轮形成期为每年的1--3月份;雌鱼年龄结构为1--7+龄,平均年龄为3.91龄,雄鱼年龄结构为1--5+龄,平均年龄为3.28龄,雌雄鱼均以3龄鱼占优势;脊椎椎体半径与全长呈线性关系:Tl-r雌鱼=107.08r+178.79(r2=0.814 0,n=132),Tl-r雄鱼=101.93r+203.01(r2=0.522 0,n=106);全长与体重关系为幂指数关系:W雌鱼=2.0x10-5xl2.880 8(r2=0.951 9,n=132),W雄鱼=2.0x10-5xl2.763 5(r2=0.938 6,n=106);用VOn bErTAlAnffy生长方程描述其生长特性,其中雌鱼l∞=673.1 CM,W∞=1 735.6 g,拐点年龄为3.75龄,拐点体重为507.4 g;雄鱼l∞=463.1 CM,W∞=465.5 g,拐点年龄为1.13龄,拐点体重为111.8 g。并比较了闽南近海与日本有明海中国团扇鳐的年轮与生长特征以及闽南近海中国团扇鳐适宜的开捕年龄、开捕全长和开捕体重。; Age structures and growth characteristics of Platyrhina sinensis samples collected monthly from February 2004 to March 2005 in southern Fujian coastal areas were studied.Nitric-acid-cobalt was used to colorate vertebrae.Results showed that: most growth rings of the vertebrae of Platyrhina sinensis were monozonal,only a few of them were double bands and multi-bands.Growth rings formed during Jan.to Mar.every year;The female fishes age structure were from 1 to 7+,the average age were 3.91,and the male age structure were from 1 to 5+,the average age were 3.28,and most of them were 3 years old;The relationship between the radius of backbone and body-length were linearity: TL-Rmale=107.08R+178.79(r2=0.814 0,N=132),TL-Rfemale=101.93R+203.01(r2=0.522 0,N=106);And the relationship between body-length and weight were power exponent: Wmale=2.0×10-5×L2.880 8(r2=0.951 9,N=132),Wfemale=2.0×10-5×L2.763 5(r2=0.938 6,N=106);And the growth equation parameters of von Bertalanffy were got by regression methods.Female: L∞ were 673.10 cm,W∞ were 1735.60 g,the spinodal age were 3.75 years old,and the inflexion of body weight were 507.40 g;Male: L∞ were 463.10 cm,W∞ were 465.50 g,the spinodal age were 1.13 years old,and the inflexion of body weight were 111.80 g.This paper compared southern Fujian coastal Platyrhina sinensis with Japan sea Platyrhina sinensis on growth rings and growth characteristics to certify the suitable catch age,body-length and weight.; 福建省基金项目“福建海洋生物物种多样性研究”课题资助
