CiiMar, Centro interdisciplinar de investigação Marinha e ambiental, universidade do Porto, rua dos Bragas 289, 4050-123 Porto, Portugal.SuMMarY: We studied the use of parasites as biological tags for discriminating fish stocks of Aphanopus carbo (osteichthyes: trichiuridae) from Portugal (Sesimbra on the mainland, Madeira and the azores). Sixteen different metazoan parasites were found (14 from Madeira, 9 from Sesimbra and 7 from the azores). Some parasites occurred only in fish from Madeira. the prevalence and mean intensity of the infection was recorded for each parasite and locality, and their values were statistically compared between the three sampling localities and related to host length classes. the differences between some of these parameters were statistically significant among the three localities or between two of them. it is suggested that 6 parasites (Tentacularia coryphaenae, Sphyriocephalus tergestinus, Campbelliella heteropoeciloacantha, Anisakis spp., Bolbosoma vasculosum and unidentified acanthocephala larvae) can be used as biological tags to discriminate Portuguese stocks of Aphanopus carbo.Keywords: parasites, biological tags, Aphanopus carbo, fish, Portugal. reSuMen: Uso de parásitos como marcadores biológicos en la identificación de stocks de sable negro, AphAnopus cArbo Lowe, 1839 (Osteichthyes: Trichiuridae) en aguas portuguesas. -Se estudió el uso de parásitos como marcadores biológicos para discriminar los stocks de Aphanopus carbo (osteichthyes, trichiuridae) de Portugal (Sesimbra en el continente, Madeira y azores islas). dieciséis parásitos metazoarios fueron encontrados (14 en Madeira, 9 en Sesimbra y 7 en azores). algunos parásitos se presentaron sólo en Madeira. la prevalencia y la intensidad media de las infecciones fueron calculadas para cada parásito y cada región, y sus valores fueron comparados estadísticamente entre los tres lugares de muestreo, y relacionados con la talla del huésped.

“…The lack of significant values for correlation between intensity of anisakids and host data was also recorded by Mladineo and Poljak (2014) for S. colias and Sardina pilchardus in the Adriatic Sea, and by Costa et al (2004) for Pagellus bogaraveo off Madeira Island. By contrast, Cruz et al (2009) recorded a significant increase in anisakid intensity according to the host length for Aphanopus carbo off Sesimbra (mainland) and Madeira Islands, Portugal. Additionally, Chou et al (2011) found significantly higher intensity of Anisakis larvae in larger and older spotted mackerel (Scomber australasicus) off the Taiwanese coast.…”

Summary:Anisakiasis is a problematic zoonotic infection associated with the consumption of raw or undercooked fish. Atlantic mackerel (Scomber colias) is of high commercial interest in Portugal and has been reported as a common host of Anisakis spp. In this study, the occurrence of anisakids is evaluated in S. colias and also Scomber scombrus, and the potential zoonotic risk associated with consumption of these two fishes is evaluated according to the recorded infection levels. These were found to be high for both fish species: a mean intensity and prevalence of 21.7 worms/fish and 85% for S. colias, and 16.4 worms/fish and 83.3% for S. scombrus, respectively. No correlation was detected between anisakid intensity and host total length, total weight, condition factor, and hepatosomatic and gonadosomatic indices for both fish species, but significantly higher intensity values were detected for more mature S. scombrus, i.e. fish recording a higher gonadosomatic index. Molecular tools allowed the identification of two species of Anisakis, A. simplex (s.s.) and A. pegreffii. They differed in their occurrence: in S. colias the prevalence of A. simplex (s.s.) was 18% and that of A. pegreffii was 82%, whereas in S. scombrus the prevalence of A. simplex (s.s.) was 73% and that of A. pegreffii was 27%. Occasionally, worms of Hysterothylacium aduncum were identified for both fish. The different infection levels of the two Anisakis species in both hosts off the Portuguese coast raise the hypothesis of a different life cycle at the level of the invertebrate intermediate host. S. colias lives in deeper waters than S. scombrus, and the differences found in infection levels suggest that A. pegreffii main first intermediate host also live in deeper waters, compared with A. simplex (s.s.) main first intermediate host. The higher infection levels of A. simplex (s.s.) (most infectious to humans) in S. scombrus suggest that its consumption when slightly cooked, as in grilled fish (so popular in Portugal), could be more problematic for the development of anisakiasis in humans than the consumption of S. colias and thus be of potential public health concern.Keywords: anisakids; Anisakis pegreffii; Anisakis simplex (s.s.); Atlantic mackerels; Portuguese coast; molecular identification; food safety.

An extensive literature review is made of the parasites in marine and freshwater fish in mainland Portugal, the Portuguese archipelagos of the Azores and Madeira, as well as in farmed fish. The host(s) of each parasite species, its location in the host, site of capture of the host, whenever possible, and all the available bibliographic references are described. The economic importance of some parasites and the zoonotic relevance of some parasitic forms are discussed. A general overview of the data is provided, and some research lines are suggested in order to increase and complement the current body of knowledge about the parasites of fish from Portugal.Keywords: Parasites, fish, pathology, economy, zoonotic diseases, Portugal. ResumoÉ feita uma revisão do conhecimento dos parasitas de peixes de Portugal com base em extensa compilação bibliográfica. São referidos os parasitas de peixes marinhos e de água doce do continente, dos Arquipélagos da Madeira e dos Açores, bem como os parasitas de peixes de piscicultura. Para cada espécie é indicado o hospedeiro, localização no hospedeiro, local de pesca quando possível, e referências bibliográficas disponíveis. Discute-se a importância econômica de alguns dos parasitas e a relevância zoonótica de algumas formas. É feita uma avaliação geral dos dados e sugerem-se linhas de pesquisa que aumentem e complementem o conhecimento atual sobre os parasitas de peixes de Portugal.
