The previously studied geographic variability in the growth patterns of different European sardine or European pilchard (Sardina pilchardus) populations has been attributed to the trophic status and productivity of the various ecosystems, as well as the genetic distance among populations. However, in the face of ocean warming and its multifaceted effects on marine populations and fisheries, it is interesting to explore growth patterns through the prism of sea temperature and dissolved oxygen. Here, data on the asymptotic length, growth coefficient, and maximum reported age of 47 Atlantic and Mediterranean sardine populations, covering the entire geographical range of its distribution, were extracted from published sources and were correlated with regional sea surface temperature and dissolved oxygen. Asymptotic length was negatively related to sea temperature and more strongly positively related to oxygen levels, indicating that sardines grow to larger body size in cooler waters that are more oxygenated. Within the context of climate change, the link of intraspecific growth variability with temperature and oxygen draws attention to the adverse effects this might have on many fish biological characteristics in a warming future.

先前研究的不同欧洲沙丁鱼或欧洲沙丁鱼 ( Sardina pilchardus ) 生长模式的地理变异性) 种群被归因于各种生态系统的营养状况和生产力，以及种群之间的遗传距离。然而，面对海洋变暖及其对海洋种群和渔业的多方面影响，通过海水温度和溶解氧的棱镜探索生长模式是很有趣的。在这里，关于 47 个大西洋和地中海沙丁鱼种群的渐近长度、生长系数和最大报告年龄的数据，涵盖了其分布的整个地理范围，是从已发表的来源中提取的，并与区域海表温度和溶解氧相关联。渐近长度与海水温度呈负相关，与氧气水平呈更强烈的正相关，表明沙丁鱼在含氧量更高的较冷水域中长到更大的体型。在气候变化的背景下，种内生长变异与温度和氧气的联系引起了人们对未来变暖可能对许多鱼类生物学特性产生的不利影响的关注。
