The helminth parasite fauna of the oceanic horse mackerel Trachurus picturatus Bowdich 1825, caught off the Madeira Islands was composed of six different taxa. Prevalence and abundance of larval Anisakis sp. (Nematoda: Anisakidae) and Nybelinia lingualis (Trypanorhyncha: Tentaculariidae), the most common parasite taxa, were 24.3%, 0.9 and 37.9%, 0.7, respectively. Bolbosoma vasculosum (Acanthocephala: Polymorphidae) and the monogeneans Heteraxinoides atlanticus (Monogenea: Heteraxinidae) and Pseudaxine trachuri (Monogenea: Gastrocotylidae) were comparatively rare. The depauperate helminth fauna of the oceanic horse mackerel at Madeira compared to other geographical regions of the north-eastern Atlantic, namely the Azores banks and the West African coast, may be attributed to the paucity of nutrients off oceanic islands and to a low density of the fish population.
在马德拉群岛附近捕获的1825年波氏竹筴鱼(Trachurus picturatus Bowdich)的蠕虫寄生虫区系由六个不同的分类单元组成。幼虫型异尖线虫属(线虫纲:异尖科)和舌形尼氏绦虫(四吻目:触手科)是最常见的寄生虫分类单元,其感染率和丰度分别为24.3%、0.9和37.9%、0.7。血管博尔博吸虫(棘头虫纲:多形科)以及单殖吸虫大西洋异斧虫(单殖吸虫纲:异斧科)和竹筴伪斧虫(单殖吸虫纲:胃殖科)相对较少见。与东北大西洋的其他地理区域(即亚速尔群岛浅滩和西非海岸)相比,马德拉群岛的竹筴鱼蠕虫寄生虫区系匮乏,这可能归因于海洋岛屿附近营养物质的缺乏以及鱼类种群密度较低。
