BackgroundThe Sultanate of Oman’s aquaculture industry is expanding with an on-going assessment of potential new fish species for culture. The king soldier bream, Argyrops spinifer (Forsskål) (Sparidae), is one such species that is under consideration. During a routine health assessment of specimens caught in the Sea of Oman throughout the period November 2009 to March 2011, a number of gill polyopisthocotylean monogeneans were recovered.MethodsA subsequent study of the monogeneans using a range of morphology-based approaches indicated that these were Bivagina heterospina Mamaev et Parukhin, 1974. In the absence of pre-existing molecular data, an expanded description of this species is provided, including a differential diagnosis with other species and genera belonging to the subfamily Microcotylinae Monticelli, 1892 with the subsequent movement of this species to a new genus to accommodate it.ResultsThe polyopisthocotyleans collected from the gills of A. spinifer appear to be unique within the family Microcotylidae Taschenberg, 1879 in that, morphologically, they possess a pair of large, muscular vaginae each armed with a full crown of 16–18 robust spines and a unique dorsal region of folded tegument, which permits their discrimination from species of Bivagina Yamaguti, 1963. Sequencing of the SSU rDNA (complete 1968 bp) and LSU rDNA (partial 949 bp) places the specimens collected during this study within the subfamily Microcotylinae, but the LSU rDNA sequence differs from Bivagina and also from other microcotylid genera. Morphological features of B. heterospina sensu Mamaev et Parukhin, 1974 and the specimens collected from the current study are consistent with one another and represent a single species. The vaginal armature of these worms is unique and differs from all other genera within the Microcotylinae, including Bivagina, and its movement to Omanicotyle n. gen. to accommodate this species is proposed.ConclusionsA new genus, Omanicotyle n. gen., is erected to accommodate Omanicotyle [Bivagina] heterospina n. comb. which represents the first monogenean to be described from Omani marine waters. Given the pathogenic potential of microcotylids on captive held fish stocks, a full assessment of Omanicotyle heterospina n. gen. et n. comb. is now required before large-scale production commences.

“…In Korea Microcotyle sebastis is considered a major parasitic disease agent as it has been related to high cumulative mortalities of net-pen farmed rockfish (Sebastes schlegeli) (Kim & Cho, 2000). In northwest Mexico, several microcotylid species have been reported from snappers from Jalisco, Nayarit, Sinaloa and Baja California Sur (Table 1).…”

“…Several studies indicate that the anthelmintic compounds praziquantel can be employed as alternative for the control of monogenean ectoparasites of marine fish (Fajer-Ávila et al, 2006;Hirazawa et al, 2000;Kim & Cho, 2000;Sharp et al, 2004;Stephens et al, 2003). Praziquantel causes spastic paralysis to the parasite and induces a calcium influx across the worm tegument, while also inhibits glucose uptake, forcing the parasite to consume its glycogen stores (DEF, 2005).…”

where he also coordinates a research group in the Graduate Program focusing on ecology and fish biology, and aquaculture research Furthermore, Dr. Carvalho teaches Cell Biology for undergraduate courses. He is national and international referee of scientific journals. This extensive research activity has resulted in scientific publications, including scientific articles, reports and book chapters in the field of Inland Fishery Resources, focusing on topics such as freshwater fish breeding, fish fauna of reservoirs, fish parasitology, limnology, fish restocking, and environmental impacts on inland aquatic environments. PrefaceAquaculture is a modality of food production that has been experiencing continuous expansion in many countries worldwide. This expansion brings the challenge of developing reliable tools for disease control, to assure high productivity of healthy seafood. The increase of farmed fish production raises the issue of achieving a sustainable and environmental friendly aquaculture. The adoption of best management practices in the whole production chain, based on "state of the art" scientific knowledge, is the key for sustainable health management. In this book, experts from several countries bring updated information about some of the main health issues that currently affects aquaculture. Topics concerning pathogens, antibiotics, probiotics, cell biology, ecological interactions, and safety are included in the six sections of this book.The first section is entitled as "Parasitic diseases", addressing issues and impacts of parasites upon aquaculture. The first chapter is the "Transmission biology of the myxozoa", which explains about the diseases that some myxozoans cause in marine and freshwater fish, and how they can be a problem for aquaculture and fishery industries. It also elucidates the life cycle of myxozoans, that involves invertebrates, and a vertebrate host that is typically a fish. However, there are no commercially available chemotherapeutants and vaccines to treat myxozoan infections. This review summarizes the current knowledge on the transmission biology of myxozoans, which would be useful for designing management strategies for related diseases. The second chapter is "Metazoan parasites of cultured European sea bass Dicentrarchus labrax (Linneaus 1758) from Corsica". It is a study relating that parasitic infections and associated diseases have emerged in aquaculture systems in many regions of Europe, resulting in significant economical losses. This study points out that wild fish are believed to be the primary reservoirs of parasite infection for fish farmed in cages, and environmental conditions in culture systems may favor disease transmission, threatening production activity. In this sense, it is considered that animals reared in sea-cages are exposed to a large number of parasitic agents. The third chapter is "Parasitic diseases in cultured marine fish in Northwest Mexico". This chapter summarizes the main parasitic diseases that affect marine fish species with aquaculture poten...

“…M. sebastis infection occurs in S. schlegelii net cages throughout the year, and high cumulative mortalities of juveniles are often observed during summer season (Kim & Choi, 1998). Because of its economic importance, there have been many studies on this monogenean, mostly focussing on the infection dynamics and chemotherapies (Kim et al, 2001;Kim & Cho, 2000;Kim & Choi, 1998).…”

The genus Microcotyle (Van Beneden & Hesse, 1863) belongs to the polyopisthocotylean monogeneans, which are gill parasites of marine fishes, mainly the perciformes (Ayadi et al., 2017). Infected host fish exhibit anaemia and dyspnoea with considerable mortality but may remain in a state of chronic infections (Kim et al., 2001;Sanz, 1992). The genus Microcotyle is the largest genus in the family Microcotylidae, currently having 69 valid species listed in the WoRMS website; however, it remains a difficult genus for classification (Bouguerche et al., 2019a(Bouguerche et al., ,2019bWoRMS, 2021). Recently, molecular tools have been applied to the Microcotyle taxonomy and several new Microcotyle species have been described by morphological re-examination and molecular analyses (Ayadi et al., 2017;
