pawak)研究斑鳍白姑鱼的年龄判定与生长特性。采用自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尾。结果认为斑鳍白姑鱼鳞片的年轮显示为MGI主要在月形成性腺成熟指数繁殖期为月份LogisticBIC渐进体长= 220.32 mm, = 0.58, 3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
fishery-dependent bottom trawl, gillnet fleets and longline fishing in the Beibu Gulf from August 2008 to May 2009 were studiedThe 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 )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 functionsto the length-at-age data. ARSS indicated that there were no significant differences in growth between sexes among the four growth models (>0.05), and the Logistic growth function was selected as the most appropriate growth model according to Akaike’s Information Criterion (AIC), AIC differences() and Bayesian information criterion . The estimated parameters for Logistic growth function were (asymptote length= 220.32 mmaverage growth rate of growth curve) 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 exploitation and utilization of
