中文摘要：通过对斑鳍白姑鱼(Pennahia pawak)鳞片年轮的观察和基础生物学测定,研究斑鳍白姑鱼的年龄判定与生长特性。采用自2008年8月至2009年5月北部湾海域底拖网、流刺网和钓具作业的斑鳍白姑鱼渔获样本,共计626尾。结果认为斑鳍白姑鱼鳞片的年轮显示为空白型窄带,边缘增长率MGI计算结果表明,年轮主要在9-11月形成,为1年1个周期;性腺成熟指数(GSI)表明,繁殖期为4-8月份,年轮形成于繁殖期之后。本研究利用最大似然法估算了von Bertalanffy、Logistic、Gompertz和Generalized von Bertalanffy生长方程的生长参数,ARSS检验得出雌雄生长在4个生长方程中均无显著性差异(P>0.05),AIC、AIC差值和BIC检验得出Logistic生长方程为最适生长模型,主要参数分别为:渐进体长L∞=220.32 mm,生长曲线的平均速率K=0.58,初始年龄t0=0.905。斑鳍白姑鱼在3龄之前生长迅速,之后生长趋于减缓。为保护产卵补充群体和合理开发利用北部湾的斑鳍白姑鱼资源,以及考虑实际渔业生产状况,建议以2龄的体长146.53 mm作为最小开捕体长标准。

外文摘要：To reveal the age and growth of pawak croaker Pennahia pawak（Lin,1940）,626 specimens collected by fishery-dependent bottom trawl,gillnet fleets and longline fishing in the Beibu Gulf from August 2008 to May 2009 were studied.The annuli in the scales were vacant narrow band,which indicated that they were formed once a year,from September to November by monthly changes in the marginal growth increment（MGI）of the scales,just after spawning from April to August.A maximum likelihood estimation procedure was used to fit the von Bertalanffy,Logistic,Gompertz and generalized von Bertalanffy growth functions to the length-at-age data.ARSS indicated that there were no significant differences in growth between sexes among the four growth models（P0.05）,and the Logistic growth function was selected as the most appropriate growth model according to Akaike＇s Information Criterion（AIC）,AIC differences（i） and Bayesian information criterion（BIC）.The esti-mated parameters for Logistic growth function were L∞（asymptote length） = 220.32 mm,K（average growth rate of growth curve） = 0.58,t0（theoretical original growth age） = 0.905.Pennahia pawak grows fast before age three,after which the growth rate tends to slow down.In order to protect the population and utilize the resources in a reasonable way,it is suggested that 146.53 mm body length with age two should be the minimum size for exploi-tation and utilization of P.pawak resources.
