The Green Jobfish Aprion virescens supports important commercial, recreational, and subsistence fisheries throughout its Indo-Pacific range. Concerns with previous estimates of age and growth from fish in Hawaii, along with evidence of variability in these parameters from locations outside the Pacific Ocean, limits their reliability as input parameters for assessments of this species, particularly in Hawaii. Previously validated aging criterion were applied to fish collected from within the Hawaiian Archipelago (main Hawaiian Islands and Northwestern Hawaiian Islands) and the eastern Indian Ocean to provide length-at-age, growth, and longevity information for stock assessment and management purposes as well as to further examine spatial variability across its range. The Bayesian information criterion was used as a measure of goodness of fit for von Bertalanffy models with different covariates to explore the influence of sex and location on growth. No divergence in growth trajectories was identified between sexes, and growth parameter estimates were not different within the Hawaiian Archipelago or between Hawaii and the eastern Indian Ocean. Empirical natural mortality estimates revealed that mortality was also very similar between sexes and among locations due to the similarity in maximum ages and growth parameter estimates. Considering there was dissimilarity in age and growth parameters between the current study and those published for this species from the Coral Sea and the western and central Indian Ocean, further investigation of potential clines in relation to latitude, and subsequently water temperature, need to be determined.

在夏威夷群岛和东印度洋之间广阔的地理范围内,绿色 Jobfish Aprion virescens 的生长和寿命明显相似

The Green Jobfish Aprion virescens支持整个印太地区重要的商业、休闲和自给渔业。之前对夏威夷鱼类年龄和生长的估计,以及来自太平洋以外地区的这些参数变化的证据,限制了它们作为评估该物种的输入参数的可靠性,特别是在夏威夷。先前验证的老化标准适用于从夏威夷群岛(主要夏威夷群岛和西北夏威夷群岛)和东印度洋收集的鱼,以提供年龄长度、生长和寿命信息,用于种群评估和管理目的以及进一步检查其范围内的空间变异性。贝叶斯信息标准被用作具有不同协变量的 von Bertalanffy 模型拟合优度的度量,以探索性别和位置对生长的影响。没有发现性别之间的增长轨迹存在差异,夏威夷群岛或夏威夷和东印度洋之间的增长参数估计值没有差异。经验自然死亡率估计表明,由于最大年龄和生长参数估计值的相似性,性别之间和地点之间的死亡率也非常相似。考虑到目前的研究与在珊瑚海和印度洋西部和中部为该物种发表的研究在年龄和生长参数方面存在差异,进一步调查与纬度相关的潜在物种,
