摘　　要： 利用2006年7月～2007年8月北部湾渔业商业捕捞流刺网和底拖网渔获物中采集的样本,对北部湾红鳍笛鲷的年龄与生长特性进行了初步研究。结果表明,北部湾红鳍笛鲷优势年龄2～4龄,占61.29%;logistic生长模型为其最适生长模型,模型中的参数分别为:L∞=808.04mm,k=0.48,t0=3.48;体长与体重的生长拐点分别为3.48龄和5.43龄。 Age and growth of crimson snapper Lutjanus erythopterus were studied according to data collected in commercial catches from drift gillnet and bottom trawl fleets in Beibu Gulf from July 2006 to August 2007. The results showed that the dominant age of Lutjanus erythopterus ranged from 2 to 4 years old, accounting for 61. 29% of the total; Logistic growth model was the most suitable model for description of the growth process of Lutjanus erythopterus. The estimated parameters for logistic growth model were L∞=-808.04mm,K= 0.48,t0 = 3.48 ; The inflection points in body length and weight curve of the stock were situated at the age of 3.48 and 5.43, respectively.
