First report of Ascarophis Van Beneden, 1871: A. Brasiliensis n.sp. (Nematoda, Ascarophidinae) and Procamallanus (Spirocamallanus) Pereira/Annereaux, 1946 (Nematoda, Procamallaninae) in South America
Abstract:Ascarophis brasiliensis recovered from the stomach of Trachinotus carolinus (L. 1766), is proposed as a new species and Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 is redescribed from a new host: Paralonchurus brasiliensis (Steind., 1875). A. brasiliensis is more closely related to A. crassicolis Dollfus & Campana-Rouget, 1956, from which it differs mainly by the absence of cervical cuticular expansion and size of the eggs. The new species is also compared to A. cooperi johnston & Mawson, 1945 and… Show more
“…In the wild, Florida pompano can host numerous pathogens. Some are acquired through their diet of crustaceans, bivalve mollusks, and other marine invertebrates (Froese & Pauly, 2021;Iverson & Berry, 1969) & Brown, 1970;Pinto, Vicente, & Noronha, 1984;Ribeiro, de São Clemente, Lopes, & Knoff, 2014;S anchez-Ramírez & Vidal-Martinez, 2002), while others such as small crustacean parasites (Bunkley- Williams, Williams, & Bashirullah, 2006;Parker & Booth, 2013) and monogenean trematodes (Kohn, Santos, & Baptista, 1992;Kohn, Santos, & Lebedev, 1996;S anchez-Ramírez & Vidal-Martínez, 2002) can be transmitted directly from fish to fish, especially during spawning.…”
Owing to their high value, in the 1950s researchers and commercial ventures began investigating the potential of Florida pompano, Trachinotus carolinus, for aquaculture; however, initial efforts did not result in commercialization. In the early 2000s, a renewed interest in pompano as a candidate for aquaculture occurred, and over the last two decades, protocols have been developed that have allowed commercialization of pompano aquaculture. Florida pompano broodstock can be readily conditioned to spawn (26-28 C) to produce large numbers of fertilized eggs year-round via hormonally induced volitional tank spawning. Larval rearing is straight forward using a standard feeding regime of rotifers, then Artemia, followed by co-feeding and weaning to microparticulate diets with metamorphosis occurring at approximately 18-25 days post hatch.Pompano readily consume formulated diets and growout of

“…Procamallanus (S.) pereirai has been reported from a variety of hosts and different geographical localities , Sogandares-Bernal 1955, Noble & King 1960, Hutton 1964, Joy 1971, Yin 1983, Sood 1989, Frost & Dailey 1994. In Brazil this nematode was referred parasitizing Paralonchurus brasiliensis (Pinto et al 1984, Vicente et al 1985. Larval stages of P. (S.) pereirai have been reported in Brazil for the teleosts Stellifer brasiliensis, Nebris microps, Porichthys porosissimus, Symphurus tesselatus and Menticirrus americanus (Santos et al1999).…”
Newly collected specimens of Procamallanus (Spirocamallanus) macaensis Vicente & Santos, 1972 from the intestine of Paralonchurus brasiliensis (Steindachner), off Rio de Janeiro, Brazil, are redescribed and genetically characterised. Additionally, all congeners deposited in the Coleção Helmintológica do Instituto Oswaldo Cruz (CHIOC) parasitic in marine fishes of the South Atlantic, including types of P. (S.) macaensis, were re-evaluated. The following features are described for the first time in P. (S.) macaensis: morphology and arrangement of cephalic structures, shape of deirids and location of phasmids. The position of the excretory pore, the number and arrangement of caudal papillae in males, the structure of the spicules and of tail end in both males and females are rectified. Most specimens deposited in the CHIOC identified as P. (S.) pereirai Annereaux, 1946 were transferred to P. (S.) macaensis and others were designated as Procamallanus (S.) sp. Procamallanus (S.) cruzi Guimarães, Cristófaro & Rodrigues, 1976 is considered a species inquirenda due to its poor description and the lack of match of its original description with the type-material re-examined. Moreover, several taxonomic problems were noted after observations of the specimens (mostly poorly preserved), including inadequate morphological reports as well as misidentifications. Phylogenies inferred using sequences of the SSU rDNA from camallanids (Nematoda: Camallanidae) mostly generated weakly supported clades; however, Camallanus Railliet & Henry, 1915 and Procamallanus Baylis, 1923 do not seem to be monophyletic. Based on the present results and the lack of molecular data, it would be pertinent to adopt the widely-used classification for the subgenera of Procamallanus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
