| Abstract |
Little information is available until now about the copepods infecting different fish species. Therefore, this study aimed to provide light on siphonostomatoids infecting Epinephelus chlorostigma. Twenty fish specimens were taken from the Red Sea coast (Jeddah, Saudi Arabia), and ectoparasitic copepods were investigated. Light microscopy and molecular tools were used to examine copepods isolated from fish. Parasitological indexes were calculated and showed that 60% of the examined fish were infected with a mean intensity of 12 parasite/fish. Morphological examination revealed that this copepod species is characterized by all unique features of the genus Hatschekia with special reference to Hatschekia sargi. The taxonomic position of the recovered species in the Hatschekiidae family within Siphonostomatoida was confirmed using phylogenetic analysis based on partial mitochondrial cytochrome c oxidase subunit I (mt COI) gene sequences. The mt COI gene query revealed that the recovered Hatschekia species is closely related to Hatschekia maculatus (gb| JQ664005.1). This study discovers a new host for Hatschekia species isolated from Saudi Arabia and conducts the first genomic investigation of the mt COI gene. |
