“…pegreffii hybrids extends their geographic distribution to the Tunisian coasts. Furthermore, the finding of recombinant genotypes and of A. simplex s.str., in S. scombrus from the North African coasts of the Mediterranean Sea, is in accordance with the migratory mode of life for this fish characterised by important movement from Atlantic to Mediterranean (Punzón et al 2004;Villamor et al 2004;Dransfeld et al 2005). The use of some endoparasite species and their infection levels as biological tags in fish stock discrimination is well documented and recurrently deeply reviewed (Beverly-Burton et al 1977;George-Nascimento 1996;MacKenzie 2002;Mattiucci et al 2002Mattiucci et al , 2004Mattiucci et al , 2005.…”

Larval forms of the genus Anisakis were reported infecting several fish species from the North African coasts of central Mediterranean Sea. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was used to investigate the occurrence of larval forms of different Anisakis species in teleost fishes and squid from North African coasts of the Mediterranean Sea and to establish the geographical and host range of these parasites in this area. A total of 282 Anisakis larvae were identified by PCR-RFLP from 13 teleost fish species and one cephalopod species captured at different sites off the Algerian, Tunisian and Libyan coasts. The type I larvae were found with a frequency of 93.62% and were identified as belonging to the following species: Anisakis simplex s.str., Anisakis pegreffii, A. simplex s.str/A. pegreffii hybrids and Anisakis typica. The type II larvae were found to belong to Anisakis physeteris, with the frequency of 6.38%. The record of A. simplex s.str/A. pegreffii hybrids, previously recorded from the Spanish and Portuguese Atlantic coasts and the Alboran Sea, extends their geographic distribution to the Tunisian coasts. The occurrence of A. simplex s.str. and hybrids away from their known area of distribution may predict the successful use of Anisakis larvae for tagging Scomber scombrus fish stocks for fisheries management purposes. Moreover, the results reported provide valuable information regarding the diversity of Anisakis species in the study area, indicating that several Anisakis sibling and morphospecies coexist in the North African coasts of the Mediterranean Sea.

“…The impossibility of getting smaller specimens in both Azores and Madeira commercial fishery due to the gear selectivity prevent the existence of a curvature in the age length data needed to a reliable adjustment of the von Bertalanffy growth equation. So, we statistically compare the mean lengths-at-age among the three geographic areas across a common age range, a criterion that has been successfully used in other species, such as megrim (Lepidorhombus whiffagonis) (Landa and Piñeiro, 2000), mackerel (Scomber scombrus) (Villamor et al, 2004), horse mackerel (Trachurus trachurus) (Abaunza et al, 2008), and black scabbardfish (Aphanopus carbo) .…”

“…In the eastern Atlantic, chub mackerel occurs from the Bay of Biscay to South Africa, including the Canary, Madeira, Azores and Saint Helena Islands and several seamounts (Castro-Hernández and Santana-Ortega 2000). It may be considered the southern congener of Atlantic mackerel S. scombrus (Villamor et al 2004). The two species overlap in the Iberian Peninsula, with Atlantic mackerel being predominant to the north and chub mackerel to the south of Lisbon (Martins and Cardador 1996).…”

SUMMARY: This study describes changes in abundance and spatial distribution of Atlantic chub mackerel in the Portuguese waters and the Spanish waters of the Gulf of Cadiz using data from acoustic surveys from 1995 to 2010 and data from the fishery since 1958. The distribution and dynamics of chub mackerel and sardine (Sardina pilchardus) are compared and species interactions are discussed. From 2007 to 2009, chub mackerel biomass, as measured acoustically, ranged between 69000 and 238000 t concentrated off the western coast (~50%) and in the Gulf of Cadiz (~30%). Portuguese landings have varied with periods of high landings around 1970 and in recent years. Since 1986 landings have been between 4000 and 23000 t. Both survey catches and commercial landings are taken mainly off the southwestern coast and one-to two-year-old individuals (20-24 cm) predominate in both. Scarcity of larger individuals may be a consequence of their deeper distribution and avoidance of fishing gear, migration of older individuals or a combination of both. In years with high abundance, the fishery expands to the northwestern areas of the Iberian Peninsula. The expansion appears to be caused by improved recruitment although other factors might have contributed (such as targeting to compensate for low sardine catches and the appearance of new markets). The complementary spatial distribution of chub mackerel and sardine and the inverse correlations between their frequency of occurrence, landings and recruitment indices suggest some interaction between the dynamics of the two species, possibly associated with climatic variation.Keywords: Chub mackerel, sardine, Portugal, pelagic ecosystem, purse seine fishery. RESUMEN: Cambios en la abundancia y distribución espacial del estornino del Atlántico (Scomber coliaS) en el ecosistema pelágico y pesquerias de Portugal. -Este estudio describe los cambios en la abundancia y distribución espacial del estornino del Atlántico en las aguas portuguesas y aguas españolas del golfo de Cádiz a partir de datos de las prospecciones acústicas 1995-2010 y datos de la pesquería desde 1958. La distribución y la dinámica del estornino y de la sardina (Sardina pilchardus) se comparan y se analiza la interacción de las especies. Durante 2007-2009, la biomasa del estornino medida acústicamente osciló entre 69 y 238 mil t y se concentró frente a la costa occidental (~50%) y en el golfo de Cádiz (~30%). Los desembarques portugueses han variado con períodos de altas capturas alrededor de 1970 y en los últimos años. Desde 1986 los desembarques han sido entre 4 y 23 mil t. Ambas capturas de campañas y desembarques comerciales se toman principalmente en la costa sur occidental y individuos de 1-2 años edad (20 a 24 cm) predominan en ambos. La escasez de individuos más grandes puede ser una consecuencia de su distribución más profunda y la evitación de las artes de pesca, la migración de los individuos mayores o una combinación de ambos. En los años de mucha abundancia, la pesquería se expande a las áreas occidentales norte d...
