Mullusbarbatus和Mullussurmuletus(Perciformes,Mullidae)是在许多沿海地区具有重要商业意义的常见海洋硬骨鱼。我们研究了在地中海南部阿尔及利亚海岸收集的两个同属Mullidae寄主中的Digenea物种群落。检查了五百七个巴巴图斯先生和一百二十三个苏穆莱特先生。在这项工作中,我们收集了与五个不同科有关的六个寄生的双基因科:以Lecithoculsum为代表的半尿科,黄斑藻的Fellodistomidae,仅从surmuletus,由Derogeneslatus引起的Derogenidae,由Proctotremabacilliovatum和最后的Opecoelidae代表的两个物种的Opecoelidesfurcatus和Porachoumfurcum。一项关键的系统研究表明,来自两种寄主鱼类的六种Digenean物种的形态测量数据明显重叠。因此,这两种鱼很可能共享相同的寄生虫群落,并简要论证了Digenean寄生虫的特异性。患病率值显示,在六百三十只Mullidae中,一百九十六人被寄生(31.11%)。统计测试表明,被寄生的鱼类宿主最多的是具有较高流行值(47.15%)的urmuletus,另一方面,他们证明了小鱼比其他人更容易被寄生。此外,据报道,不同寄生虫之间缺乏同质性。我们还注意到,阶乘对应分析(FCA)的使用允许我们,首次突出了根据季节在两种鱼中确定的寄生虫物种的分布。
Mullus barbatus and Mullus surmuletus (Perciformes,
Mullidae) are a common marine teleost of great commercial importance in many coastal areas. We studied the communities of Digenea species in two congeneric
Mullidae hosts collected on the Algerian coast in the southern Mediterranean. Five hundred and seven M. barbatus and one hundred and twenty-three M. surmuletus were examined. During this work, we collected six species of parasitic Digenea which are related to five different families: Hemiuridae represented by Lecithocladium excisum, Fellodistomidae by Proctoeces maculatus and which is reported only from M. surmuletus, Derogenidae by Derogenes latus, Monorchiidae by Proctotrema bacilliovatum and finally Opecoelidae represented by two species Opecoeloides furcatus and Poracanthium furcatum. A critical systematic study revealed an apparent overlap in morphometric data of the six Digenean species from two host fishes. Therefore, the two mullet species are likely to share the same parasite community, and the stenoxenic specificity of Digenean parasites is briefly argued. Prevalence values showed that in the midst of six hundred and thirty
Mullidae, one hundred and ninety-six are parasitized (31.11 %). Statistical tests showed that the most parasitized fish hosts are M. surmuletus with a high prevalence value (47.15 %), and on the other hand, they proved that small fish are more parasitized than others. Also, the lack of homogeneity between the different parasites is reported. We also note that the use of factorial correspondence analysis (FCA) allowed us, for the first time to highlight the distribution of the parasite species identified in the two mullets according to the seasons.
