Order By: Relevance

“…Contrasting patterns garnered using different tools for unravelling spatial population structure is a relatively common finding, and also increasingly documented in marine populations (Abaunza et al 2008, Sala-Bozano et al 2009, André et al 2011, SalaBozano & Mariani 2011, Yebra et al 2011. When com paring neutral genetic markers with phenotypic features putatively associated with ecological functions (McKay & Latta 2002), the objective is to explore in what way and to what extent neutral and adaptive processes differ in shaping the evolutionary trajectories of species.…”

“…a number of studies has shown that parasites may be used as biological tags in the discrimination of fish stocks from different geographical localities (Marcogliese et al, 2003;oliva et al, 2004;Marques et al, 2005;Melendy et al, 2005;McClelland and Melendy, 2007;Mackenzie et al, 2008;Ferreira Marques et al, 2009). review articles on this subject, including the procedures and methods employed in the use of parasites as biological tags, may be found in Mackenzie and abaunza (1998;, Mosquera et al (2000), Mackenzie (2002, 2004), timi (2007), abaunza et al (2008) and lester and Mackenzie (2009. the ideal tag parasite is a parasite that has significantly different levels of infection among localities which persist for a long period (a permanent parasite), that is easily detected and identified, and that does not cause serious damage to the host abaunza, 1998, 2005).…”

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. Se encontraron diferencias estadísticamente significativas entre algunos de estos parámetros de las tres regiones o entre dos de ellas. Se sugiere que 6 parásitos (Tentacularia coryphaenae, Sphyriocephalus tergestinus, Campbelliella heteropoeciloacantha, Anisakis spp., Bolbosoma vasculosum y larvas no identificadas de acanthocephala) pueden ser usados como marcadores biológicos para discriminación de stocks de Aphanopus carbo de Portugal.

“…Several genetic techniques (allozyme, mitochondrial dna, microsatellite dna, SScp) have been used in stock identification in both pelagic comesaña et al, 2008;kasapidis and Magoulas, 2008) and demersal (roldan et al, 1998) species. the results have not always been conclusive, showing, for example, low levels of genetic differentiation in horse mackerel (abaunza et al, 2008) and a high level of differentiation in hake (cimmaruta et al, 2005).…”

Stock structure of black scabbardfish (<i>Aphanopus carbo</i> Lowe, 1839) in the southern northeast Atlantic

SuMMarY: Black scabbardfish stock structure is still unknown in european waters where, due to the scarcity of biological information, the IceS considers that there is a single stock unit. this study is the final outcome of a scientific project that applies a holistic approach to research on the population structure of the black scabbardfish and aims to define the most appropriate strategy for the conservation of this resource in southern ne atlantic waters. the factors studied include life history parameters, otolith shape analysis, parasites, landings-and-effort data and contaminants. Sampling was conducted between 2005 and 2007 in three areas of the southern ne atlantic: mainland portugal, Madeira and the azores. the mainland and the azores have an established commercial fishery, whereas the azores has only an exploratory fishery. the majority of results indicated the existence of different stocks of black scabbardfish in the study area. of the 8 parameters, 6 were in agreement with separate stocks between the mainland and Madeira, 5 were in agreement with separate stocks between the mainland and the azores, and 4 were in agreement with separate stocks between Madeira and the azores.Keywords: Aphanopus carbo, black scabbardfish, stock identity, holistic approach, northeast atlantic.reSuMen: Estructura de stock de sable negro (AphAnopus cArbo Lowe, 1839) en el sur del Atlántico nordeste. -La estructura de la población de sable negro en las aguas europeas es todavía desconocida y, debido a la escasez de la información biológica disponible, IceS ha considerado una sola unidad de stock en la totalidad de dichas aguas. el proyecto que originó este estudio es un trabajo integrado para investigar la estructura poblacional de sable negro y pretende definir la estrategia más apropiada para la conservación de este recurso en aguas del sur del atlántico nordeste. para cumplir con el objetivo del proyecto se llevaron a cabo varios estudios: determinación de parámetros que definen el ciclo vital, análisis de forma del otolito, parásitos, datos de desembarques y esfuerzo pesquero, y contaminantes. el muestreo fue realizado entre 2005 y 2007 en tres áreas del sur del atlántico nordeste: portugal continental, aguas de Madeira y azores. Las dos primeras áreas tienen una pesquería comercial establecida, mientras que en azores existe una pesquería exploratoria. La mayoría de los resultados concluyeron la existencia de diferentes unidades poblacionales del sable negro en el área sur del atlántico nordeste. Seis de los ocho parámetros confirman la separación entre los individuos del continente y Madeira, mientras que 5 parámetros corroboran la separación entre el continente y azores. Solamente 4 técnicas corroboran la separación entre Madeira y azores.Palabras clave: Aphanopus carbo, sable negro, identidad de stock, aproximación holística, atlántico nordeste.
