A helminthological analysis was performed on 91 specimens of the porkfish, Anisotremus virginicus (Linnaeus) (Haemulidae), captured in coral reef habitats of the Parque Nacional Sistema Arrecifal Veracruzano (PNSAV) (Veracruz Reef System National Park), in Veracruz, Mexico. A total of 22 helminth taxa were recorded: 9 digeneans, 6 monogeneans, 1 cestode, 4 nematodes, and 2 acanthocephalans. From the 22 taxa, 11 are new host records and 7 are new geographic records. The highest prevalence was found for Monorchis latus Manter, 1942 (69%), and Mexicana anisotremumCezar, Paschoal and Luque, 2012 (68%), and the highest mean intensity was found for M. anisotremum (19.6), M. latus (18.9), and Dollfusentis chandleri Golvan, 1969 (10.8). Other important values were the component community richness (S = 22), diversity (Shannon index H' = 1.6), and infracommunity level (S = 3.1 ± 1.4; Brillouin index, H = 0.52 ± 0.3), which were similar to those found in other marine fish at the same study site. Our result represents a significant range extension for several helminth taxa. The parasite communities of A. virginicus rank among the richer parasite communities of neotropical marine fishes. In addition, the results reveal the PNSAV is a diverse area for the parasite assemblage of neotropical reef marine fishes, particularly of haemulids but also for other fish families.
对在墨西哥韦拉克鲁斯州的 Parque Nacional Sistema Arrecifal Veracruzano(PNSAV)(韦拉克鲁斯礁系统国家公园)的珊瑚礁栖息地捕获的 91 条尖鼻鲷(Anisotremus virginicus(Linnaeus))(Haemulidae)进行了寄生虫学分析。共记录了 22 种寄生虫:9 种吸虫,6 种单殖吸虫,1 种绦虫,4 种线虫和 2 种棘头虫。在这 22 个分类单元中,有 11 个是新的宿主记录,7 个是新的地理记录。Monorchis latus Manter,1942(69%)和 Mexicana anisotremumCezar,Paschoal 和 Luque,2012(68%)的发现率最高,而 M. anisotremum(19.6),M. latus(18.9)和 Dollfusentis chandleri Golvan,1969(10.8)的平均强度最高。其他重要值是群落丰富度(S = 22),多样性(Shannon 指数 H' = 1.6)和亚群落水平(S = 3.1 ± 1.4;Brillouin 指数,H = 0.52 ± 0.3),与在同一研究地点发现的其他海洋鱼类相似。我们的结果代表了几个寄生虫类群的重要范围扩展。A. virginicus 的寄生虫群落属于新热带海洋鱼类中寄生虫群落较丰富的群落之一。此外,研究结果表明,PNSAV 是新热带礁区海洋鱼类寄生虫组合的多样化区域,特别是 haemulids 鱼类,也包括其他鱼类科。
