摘　　要：利用脊椎骨鉴定 2004年5～7月于南沙群岛珊瑚礁海域捕获的黑边鳍真鲨的年龄,进一步推算其Von Bertalanffy生长方程.结果表明：南沙群岛珊瑚礁海域黑边鳍真鲨优势年龄组为雌性5～7a,雄性4～7a;v-b生长方程相关参数为：K=0.127,L∞=188cm,t0＝-1.442a;其重量生长的拐点年龄为8.22a.Carcharhinus limbatus belongs to Carcharhiniformes, Carcharhinoidei, a modest-sized shark widespread in warm-temperate, subtropical and tropical waters. There was little information about its life history. In this report, age and growth of C. limbatus are studied with vertebral specimens collected by three-ply gill net in waters of Nansha Islands from May to July 2004 using threeply gill net. The results are as follows： a majority of C. limbatus was 5 -7a （year） old for female and 4 - 7a old for male. The parameters of v-b growth equation for C. limbatus ： K = 0. 127, L∞ = 1 880mm, t0 = - 1. 442a; the age at inflection point for growth equation of weight was 8.22a.
