Helminofauna da sarda (Scomber scombrus L. ) peixe da Costa Continental Portuguesa

Abstract

Dos primerios 80 espécimens da sarda examinados (de janeiro a maio de 1982), apenas seis (7,5%) estavam livres de helmintos, apresentando os demais as espécies de parasitos seguintes, por ordem de freqüência dentro de cada grupo taxonômico: Kuhnia scombri (Kuhn, 1829) e Grubea cochlear (Diesing, 1858) (classe Monogenea); Lecithocladium excisum (Rudolph, 1819) e Opechona basillaris (Molin, 1859)(classe Digenea); pelrocercoides de Lacistrorhynchus tenuis (Beneden, 1858) de Scolex pleuronectis (Muller, 1788) e de Echeneibothrium sp. (classe Cestoda); Rhadinorhynchus tenuicornis (Linton, 1891) (filo Acanthocephala); formas dos tipos larvares Anisakis e Contracaecum e ainda, larvas de Goezia sp. (classe Nematoda). São referidas, pela primeira vez, neste hospedeiro, formas larvares do cestóide Echeneibothrium sp. e do nematóide Goezia sp.<br>Among fishes of importance in the Portuguese diet is the mackerel with a large geographical distribution in the Northern Hemisphere. The authors plan to recover the helminths of this host during the year, for taxonomic, zoogeographic and seasonal variation elements studies of potential importance to Public Health. Only six (7.5%) of the first 80 hosts examined (from January to May 1982) were not parasitized. In this paper we report the presence, by order of their frequency in each taxonomic group, of the following helminths: Kuhnia scombri (Kuhn, 1829) and Grubea cochlear (Diesing, 1858) (class Monogenea); Lecithocladium excisum (Rudolphi, 1819) and Opechona bacillaris (Molin, 1859) (class Digenea); plerocercoids of Lacistorhynchus tenuis (Beneden, 1858), of Scolex pleuronectis (Muller, 1788) and of Echeneibothrium sp. (class Cestoda); Rhadinorhynchus tenuicornis (Linton, 1891) (phylum Acanthocephala); larval forms of Anisakis and Contracaecum as well as larvae of Goezia sp. (class Nematoda).Larval forms of the cestode Echeneibothrium sp. and the nematode Goezia sp. are reported in this host, for the first time

Infecção e susceptibilidade de três espécies de peixe do rio Paraná, Presidente Epitácio, Estado de São Paulo, Brasil, a larvas de Contracaecum sp. (Nematoda: Anisakidae)

“…This fact was due to the presence of the nematode in rainy months (October, November/2000), as well as in the drought period (June, July, August/2001). The prevalence in H. malabaricus was very high when compared with those observed in the literature: S. scombrus (8.7%) (Rego et al, 1985); fish from the Baltic Sea (20%) (Valtonen et al, 1988); fish from the Penisula of Yucatan, México (46%) (Moravec et al, 1995); several fish species from Venezuela (9 to 100%) (Moravec et al, 1997) and Engraulis anchoita from the Argentina and Uruguai Seas (39.7%) (Timi et al, 2001). High prevalence of Contracaecum sp.…”

“…The majority of papers are limited to occurrence or description reports (Wooten, 1978;Rego et al, 1985;Moravec et al, Acta Scientiarum. Animal Sciences Maringá, v. 25, no.…”

Comparison of anisakid infection levels between two species of Atlantic mackerel (<em>Scomber colias</em> and <em >S. scombrus</em>) off the Atlantic Portuguese coast

“…The high infection levels (83%-85% prevalence) recorded for both fish are greater than the 10% reported for S. scombrus off continental Portugal by Rego et al (1985), and the 69.5% reported for S. colias off the Madeira Islands, Portugal, by Costa et al (2003). However, they are lower than the 100% reported for S. colias off the Azores Islands, Portugal, by Shukhgalter (2004).…”

“…There are also several records from African countries (Abattouy et al 2011, Farjallah et al 2008, Kijewska et al 2009). So far, no updated information is available for Atlantic mackerels fished off continental Portugal, and no attempt has been made to identify the anisakids isolated from S. scombrus to the species level (Rego et al 1985).…”

Anisakis simplexcomplex (Nematoda: Anisakidae) in zooplankton communities from temperate NE Atlantic waters

“…C of Mattiucci et al (1997) in Mattiucci et al (2014) differing in their genetic structure, life history and geographic distribution. In the northeast Atlantic Ocean, two of them (A. simplex s.s. and A. pegreffii) have been described as having a sympatric distribution among their hosts (Rêgo et al 1985;Abollo et al 2001).…”
