Metazoan parasites and their hosts experience the environmental influence of the seasonal presence of Western and Eastern subzones with different oceanographic conditions on the Yucatan continental shelf (YS). In addition, natural seeps and oil transport in the area lead to the presence of hydrocarbons. We hypothesized that the parasite infrapopulations and infracommunities of Haemulon aurolineatum will respond to environmental variability related with ongoing oceanographic subzone conditions of the YS. Spatial and multivariate statistical analyses were used to test this hypothesis. For 17 sampling sites along the YS, 55 parasite morphospecies were recovered from 146 fishes. There were significant differences in the number of parasite species between Western and Eastern subzones, but not in the number of parasite individuals. Spatial autocorrelation on environmental variables as a consequence of the Yucatan current was found. Overall, the parasite metrics suggested a region with a good ecosystem health condition naturally influenced by oceanographic processes.

后生动物寄生虫及其寄主在尤卡坦大陆架 (YS) 上经历了具有不同海洋条件的西部和东部分区的季节性存在的环境影响。此外，该地区的天然渗漏和石油运输导致碳氢化合物的存在。我们假设 Haemulon aurolineatum的寄生虫群落和群落将响应与 YS 正在进行的海洋分区条件相关的环境变化。空间和多变量统计分析用于检验这一假设。在 YS 沿线的 17 个采样点，从 146 条鱼中回收了 55 种寄生虫形态物种。西部和东部分区之间的寄生虫种类数量存在显着差异，但寄生虫个体数量没有显着差异。发现了尤卡坦洋流导致的环境变量的空间自相关。总体而言，寄生虫指标表明该地区具有良好的生态系统健康状况，自然受到海洋学过程的影响。
