Helmintofauna de cavalas, Scomber japonicus Houtt, do Rio de Janeiro

Abstract

Os autores identificaram as seguintes espécies de helmintos, coletados de 50 cavalas, Scomber japonicus, no Rio de Janeiro: Kuhnia scombri (Kuhn, 1829) e Grubea cochlear (Diesing, 1858) (Monogenea); Opechona orientalis (Layman, 1930), Lecithocladium harpodontis Srivastava, 1942 e Nematobothrium scombri (Taschenberg, 1879) (Digenea); plerocercos de Trypanorhyncha Scolex pleuronectis Müller, 1788 e Rhinebothrium sp. (Cestoda); Bolbosoma sp. (Acanghocephala) e Anisakidae larvares (Nematoda), identificados aos tipos larvares Raphidascaris, Phocanema, Contracaecum e Anisakis tipo 1. Os digenéticos foram os de maior incidência, 84% dos peixes mostraram-se parasitados por uma ou mais espécies. Quanto às espécies, a de maior incidência foi Nematobothrium scombri (Digenea, Didymozoidae), em 46% dos peixes. São pela primeria vez assinalados Scomber japonicus larvas de Phillobothiidae, possivelmente Rhinebothrium, além de larvas de Anisakis do tipo 1. São pela primeira vez assinaladas no Brasil as espécies, Grubea cochlear, Kuhnia scombri, Nematobothrium scombri e Opechona orientalis.<br>There were identified twelve species of helminths from fifty "Spanish Mackerel", Scomber japonicus Houtt, in Rio de Janeiro; Kuhnia scombri (Kuhn, 1829), and Grubea cochlear (Diesing, 1859) (Monogenea); Opechona orientalis (Layman, 1930), Lecithocladium harpodontis Srivastava, 1942 e Nematobothrium scombri (Taschengerg, 1879) (Digenea); plerocercus of Trypanorhyncha, Scolex pleuronectis Müller, 1788 and Rhinebothrium sp. (Cestoda); Bolbosoma sp. (Acanthocephala) and larval Anisakidae (Nematoda), types Raphidascaris, Phocanema, Contracaecum and Anisakis I. Larval Phillobothriid, following species are referred in Brazil for the first time: Grubea cochlear, Kuhnia scombri, Nematobothrium scombri and Opechona orientalis

Gill monogeneans of the chub mackerel, Scomber japonicus from Madeiran waters of the Atlantic Ocean, Portugal

“…Grubea cochlear differs significantly from the other species by its larger size (up to 10 mm in length). The low number of individuals of G. cochlear both in the present study (five individuals) and elsewhere (see Rohde, 1986) do not allow conclusive statements about the geographical variation of the species, although the species has been recovered from S. scombrus and S. japonicus from the Atlantic Ocean, Mediterranean and Indo-Pacific waters (Rego & Santos, 1983; Rohde, 1986; Somdal & Schram, 1992; Alves et al , 2003).…”

Diversity of Monogenoidea parasitizing scombrid fishes from Rio de Janeiro coast, Brazil

“…Research on monogenoidean parasites of scombrid fishes from Brazil had been conducted by Abdallah et al (2002), Alves and Luque (2006), Kohn and Justo (2006), Kohn et al (2003), Kohn et al (2004), Mogrovejo and Santos (2002), Mogrovejo et al (2004), Oliva et al (2008), Price (1938), Rego and Santos (1983), Rohde (1986), Rohde and Hayward (1999) and Rohde and Watson (1985). The aim of this study is to contribute to the increase of the knowledge and expansion of the geographical distribution of monogenoidean parasites in different species of Scombridae in the area of the Southwestern Atlantic Ocean.…”
