摘要

本研究调查了寄主特征、栖息地和采样季节对三种鸭嘴鱼寄生虫流行率和强度的影响。取样的三个宿主物种分别是暗纹东方鲀(Platycephalus fuscus,n = 3)、蓝点东方鲀(Platycephalus caeruleopunctatus,n = 38)和虎斑东方鲀(Platycephalus richardsoni,n = 59)。在 2020 年 7 月至 2021 年 9 月的 15 个月中,共收集到 14 种元虫寄生虫。发现的寄生虫包括一种软骨鱼纲桡足类、成体半知母吸虫、绦虫类、幼体和成体棘尾吸虫、幼体和成体线虫以及一种未知种类的蠕虫。一般线性模型用于评估宿主特征和采样季节与寄生虫感染强度之间的关系。结果发现,一种未确定的疟原虫对草履虫的感染强度与采样季节以及宿主质量与性别的交互作用都有显著关系。在 P. richardsoni 中,棘尾虫 Corynosoma sp.的感染强度与采样季节相关。富贵鱼的寄生虫类群丰富度最高,这可能是由于富贵鱼的深度范围很广,再加上它是通食动物。

How host ecology influences the parasite communities of three Australian flathead fishes, Platycephalus spp. (Scorpaeniformes: Platycephalidae).

This study investigated the role of host traits, habitat, and sampling season on the prevalence and intensity of parasites in three species of platycephalid fishes. Three host species sampled were dusky flathead (Platycephalus fuscus, n = 3), blue-spotted flathead (Platycephalus caeruleopunctatus, n = 38), and tiger flathead (Platycephalus richardsoni, n = 59). A total of 14 metazoan parasite species were collected over 15 months, between July 2020 and September 2021. The parasites found included a chondracanthid copepod, adult hemiuroidean trematodes, cestode plerocercoids, larval and adult acanthocephalans, larval and adult nematodes, and an unknown species of helminth. General linear models were used to assess the relationship between host traits and sampling season with parasite infection intensity. The infection intensity of an unidentified plerocercoid species in P. caeruleopunctatus was found to be significantly associated with both sampling season and the interaction of host mass with sex. In P. richardsoni the infection intensity of the acanthocephalan, Corynosoma sp. was found to correlate with sampling season. The highest richness of parasite taxa was recorded from P. richardsoni, which may be due to the wide depth range of P. richardsoni, coupled with its generalist diet.
