2007, English version Ecoparasitogy of Deep Fishes from Portugal
The present work is the first study of parasitofauna of the Portuguese Coast that includes some species of deep fishes (12 orders, 18 families and 24 species). Works of this type in Portugal had basically appeared associates only to a host, the black-scabbard fish , in two areas: Sesimbra and Madeira. For the first time a parasitological study was made in Paralepis atlantica, where we find Digenea 1 and Anisakis sp. Cestode Paragrillotia sp. that parasite Lycodes vahlii presented very different morphometric characteristics from that it is registered for the described species, being very possibly a new species. In this study 34 species of metazoan parasites had been found. The following parasites and in the respective hosts had been detected for the first time: Amphipoda in Sebastes fasciatus; Anisakis sp. in Alepocephalus bairdii; Ascaridida in Synaphobranchus kaupi; Capillaridae in L. pallidus; Contracaecum sp. in Diretmus argenteus; Cucullanus sp. in Notacanthus chemnitzii; Digenea 5 in Cottunculus thomsonii; Hysterothylacium sp. in L. pallidus and L. vahlii; Lecithophyllum botryophorum in L. vahlii; Litobrothidae in Anarhichas lupus; Lophoura edwardsi in S. kaupi; Paragrillotia sp. in L. vahlii; Rhabdochonna sp. in L. vahlii; Raphidascaris sp. in Macrourus berglax; Steringophorus sp. in L. vahlii; Spinitecus sp. 2 in Glyptocephalus cynoglossus; Spinitecus sp. 3 in C. thomsonii; Spirurida in M. berglax; Tetraphyllidae larva 1 in A. bairdii. Although the following species of parasites and respective hosts had been already cited in previous studies and other geographic regions, with this work had been detected for the first time in Portugal: Anisakis sp. in R. hippoglossoides and M. berglax ; b) Contracaecum sp. in Reinhardtius hippoglossoides and S. fasciatus; c) Corynossoma sp. in R. hippoglossoides; d) Hysterothylacium sp. in M. berglax; e) Sphyrion lumpi in M. berglax; f) Spinitectus sp. 1, in M. berglax. In that it respects to the species of more frequent parasites in this inquiry we have: Digenean - Steringophorus sp. and Lecisthaster sp.; Nematoda- Anisakis sp.; Contracaecum sp. and Hysterothylacium sp. and Copepoda - Sphyrion lumpi. The orders of fish that in this study had shown greater diversity of parasites had been Perciformes; Gadiformes; Pleuronectiformes; Scorpaeniformes and Osmeriformes. The orders that in this study had not met parasites had been: Myctophiformes; Squaliformes and Stomiiformes. Relatively to A. carbo, this is the first study of the community of parasites of the black-scabbard fish of the Açores, that presented as dominant species Anisakis sp. In our study, the community of R. hippoglossoides parasites presented as dominant species Anisakis sp. and Contracaecum sp., with high intensities. Determined fish analyzed here they present species responsible parasites for zoonosis. are they : some anisakids, B. vasculosum, and Corynosoma, sp. which that they have commercial interest: A. carbo; M. berglax; R. hippoglossoides; S. fasciatus and S. mentella pointing for create measures of prevention in order to prevent the contamination of human being.
