The family Scombridae consists of 15 genera and 49 species of epipelagic marine fishes (mackerels, bonitos and tunas). These fish are of commercial and recreational importance throughout the world's fisheries (Murugesh, 1995). The Egyptian Mediterranean waters have two species of this genus, Scombermorus tritor, (Cuvier and Valenciennes, 1832) -(first record) a species native to the Atlantic, can be spotted in the Canary Islands, Senegal, Gulf of Guinea, and Angola . Scombermorus commerson is a Red Sea immigrant from the Indo-West Pacific (Lester et al., 2001; Pauly and Froese, 2016) migrated to the eastern Mediterranean Sea by the way of the Suez Canal. El Sayed (1994) and Rizkalla (1997) recorded this species in Egyptian waters. The gill apparatus of a mackerel, a common habitat for ectoparasites, is composed of five paired units: the pseudobranch, attached to the operculum and four regular gill arches. Pelagic fishes, such

Fish are frequently regarded as the most significant source of income due to their high economic value. The infection of monogeneans is the main cause of fish anemia leading to high mortalities. Thus, this study aimed to detect monogeneans parasites in Scoberomorus commerson and investigate the histopathological changes related to its natural infections. Furthermore, to research the potential parasite-host interactions. One hundred marine fishes (S. commerson) from the Ezbet-El Borg area, Damietta province, Egypt were examined from August 2022 to January 2023 for the presence of monogenean gill parasites. 38 fish were infected with monogenean species: Pricea multae 32% and Gotocotyla acanthura 19%. The structure of P. multae and G. acanthura were explained by using light and scanning electron microscope (SEM), the infected fish have no pathognomonic lesions, but for a few cases showed excessive mucus secretion. The pathological and ultrastructural results revealed massive branchial damage with partial to complete lamellar fusion and lamellar desquamation with complete loss of secondary lamellae and lymphocytic infiltration, the host response includes the appearance of numerous ruffled lymphocytes and mucous globules at the site of parasitic attachment.

“…The soldier bream is an active carnivorous species feeding particularly on sardines and benthic invertebrates (Ghanem et al, 2021). Fish are well known to be parasitized by many eukaryotic organisms (M'Rabet et al, 2016) and the gills of fish represent one of the biotopes mostly exploited by different parasites, including monogeneans (Shawket et al, 2018).…”

“…The knowledge of parasitic communities makes researchers recognize the role of host fish in the food web or ecosystem and provide a deeper assessment of the role of parasites in affecting fish health (Shawket et al, 2018). The gills in fish are important organs of examination in disease diagnosis, because of their direct contact with the environment, such as several irritants, parasites and pollutants present in the water.…”

“…The gills in fish are important organs of examination in disease diagnosis, because of their direct contact with the environment, such as several irritants, parasites and pollutants present in the water. The host and parasite relationship in the case of monogeneans results in largescale damage on the site of attachment (Shawket et al, 2018). To attach themselves to a host, monogeneans use a specialized organ called a haptor (Arya and Singh, 2020).…”

Background: Sparidae is a fish family that belongs to the order Perciformes and is commonly known as sea breams and porgies. Many species are included in this family and divided into 71 genera that could be barcoded using mitochondrial DNA genes. These fish are vulnerable to different parasitic taxa that affect fish status. The present study is aimed to confirm the molecular status of Argyrops filamentosus fish via the mitochondrial cytochrome c oxidase (COI) gene and to study the pathological changes of gills infested by monogenean parasites. Methods: Thirty Argyrops filamentosus fish were collected from Jeddah (Saudi Arabia) and identified molecularly via the mtCOI gene. Also, gills were isolated and examined microscopically for presence of monogeneans. Histopathological impacts of monogeneans on fish gills were studied in comparison to the gills of non-infected fish. Result: The DNA of fish species was barcoded and showed highly stringent criteria with the previously Argyrops filamentosus sequence data. The obtained host DNA sequences were deposited in NCBI database under accession number OP975758.1. Examination of the investigated fish gills revealed the presence of three monogenean species Protolamellodiscus senilobatus Kritsky, Jiménez-Ruiz and Sey, 2000, Acleotrema maculatus Morsy, El-Fayoumi and Fahmy (2014) and Haliotrema susanae Soo, 2019. Monogenean parasites penetrated deeply with their haptor to the gill lamella and caused damage and degeneration of epithelial cells leading to the formation of a cup-shaped depression. Therefore, the mtDNA gene has the ability for host identification and heavy monogeneans infections lead to severe damage to fish gills.
