“…Skin monogeneans were counted as described in Section 2.5. B. seriolae and N. girellae are clearly distinguishable according to their anterior morphology (Kinami et al, 2005). The remaining fish were reared for 7 day, and their feeding behavior was observed.…”

“…Notably, greater amberjack seems to be one of the most susceptible hosts (Ohno et al, 2008), among numerous N. girellae-infected Japanese marine farmed species (Ogawa et al, 1995). Given that N. girellae and B. seriolae are difficult to distinguish during inspection, Kinami et al (2005) suggested a practical method for the classification of the two skin flukes species, which is based on the different shape at the anterior end in the midline of the helminths. Neobenedenia melleni has been detected in greater amberjack raised in the Canaria islands (S anchez-Garc ıa et al, 2015), while naturally infected fish with N. girellae have been used in experimental trials in the same area (Fern andez-Montero et al, 2019).…”

Greater amberjack (Seriola dumerili) is a very promising candidate for the diversification of the Mediterranean aquaculture due to its high demand, excellent flesh quality and high market prices. Its production expansion has, however, failed so far, due to several bottlenecks mainly related to pathology. This review addresses the major pathogens, which hinder the culture of greater amberjack with special focus in the Mediterranean region, and highlights possible treatment solutions. Among the important recorded pathogens of caged greater amberjack in the Mediterranean, the gill monogenean Zeuxapta seriolae seems to be the most problematic, causing significant losses. While formalin immersions are inefficient to combat this parasite, baths with hydrogen peroxide are extremely effective and praziquantel administration could be a more practical in-feed treatment solution. The digenean blood flukes, Paradeontacylix spp., also account for important losses in greater amberjack farms in the same region. Dietary administration of praziquantel constitutes an effective therapeutic measure against those infections. Vibrio harveyi is also a bacterial pathogen severely affecting fish maintained both in land-based facilities and in cages, whereas Epitheliocystis is a disease reported frequently that can be fatal when it occurs at early stages. Skin flukes such as Benedenia seriolae and Neobenedenia girellae as well as other parasites bacteria and viruses mentioned herein, which have caused substantial losses in Asian enterprises, but have not been identified yet in greater amberjack farmed in the Mediterranean, should be considered as potential threats.

“…Briefly, B. seriolae parasites were detached from fish body by freshwater bathing and were stored in RNA stabilization reagent or 75% ethanol until further use. All parasites were morphologically identified as B. seriolae based on the criteria described by Kinami et al (2005).…”

Infection with monogenean skin flukes, including Benedenia spp. and Neobenedenia spp., is one of the most important parasitic diseases in Seriola spp. aquaculture worldwide. Skin flukes adhere to host body surface and consume skin tissue. Skin fluke infection itself is not lethal, but affected fish scratch themselves on objects and make skin abrasions, rendering them more susceptible to fatal secondary infections. There is no available vaccination against skin flukes, and the extensive use of anthelmintics might worry consumers. Thus, farmers resort to regular freshwater bathing to remove the parasites from the affected fish and frequently replace and/or clean cage nets to remove parasite eggs. Benedenia seriolae is a major monogenean parasite affecting cultured Seriola spp. (Ogawa et al., 1995; Ogawa, 2015; Ogawa and Shirakashi, 2017). In contrast to Neobenedenia girellae, another major monogenean parasite that affects various marine teleosts, B. seriolae parasitizes exclusively on Seriola spp.
