Abstract:
The aim of this study was to measure selected metal concentrations inTrachurus trachurus,Trachurus picturatus, andTrachurus mediterraneus, which are widely consumed in Spain. Principal component analysis suggested that the variable Cr was the main responsible variable for the identification ofT. trachurus, the variables As and Sn forT. mediterraneus, and the rest of variables forT. picturatus. This well-defined discrimination between fish species provided by mineral element allows us to distinguish them on the basis of their metal content. Based on the samples collected, and recognizing the inferential limitation of the sample size of this study, the metal concentrations found are below the proposed limit values for human consumption. However, it should be taken into consideration that there are other dietary sources of these metals. In conclusion, metal contents in the fish species analyzed are acceptable for human consumption from a nutritional and toxicity point of view.

Abstract:
AbstractThe helminth parasite fauna of the oceanic horse mackerel Trachurus picturatus Bowdich 1825, caught off the Madeira Islands was composed of six different taxa. Prevalence and abundance of larval Anisakis sp. (Nematoda: Anisakidae) and Nybelinia lingualis (Trypanorhyncha: Tentaculariidae), the most common parasite taxa, were 24.3%, 0.9 and 37.9%, 0.7, respectively. Bolbosoma vasculosum (Acanthocephala: Polymorphidae) and the monogeneans Heteraxinoides atlanticus (Monogenea: Heteraxinidae) and Pseudaxine trachuri (Monogenea: Gastrocotylidae) were comparatively rare. The depauperate helminth fauna of the oceanic horse mackerel at Madeira compared to other geographical regions of the north-eastern Atlantic, namely the Azores banks and the West African coast, may be attributed to the paucity of nutrients off oceanic islands and to a low density of the fish population.

Abstract:
AbstractLarval stages of Anisakis spp. (Nematoda: Anisakidae) were found encapsulated or free in the viscera and abdominal cavity of the black-scabbard fish, Aphanopus carbo, chub mackerel, Scomber japonicus and oceanic horse mackerel, Trachurus picturatus in Madeiran waters. The prevalence of infection reached 97.2% (n=142) for A. carbo, 69.5% (n=154) for S. japonicus and 62.5% (n=40) for T. picturatus. Considerable differences in parasite intensities between A. carbo and both S. japonicus and T. picturatus were found, with mean intensities up to 69.6 in A. carbo, while in the other two fish hosts the intensity reached only a maximum of 2.6. These differences were probably due to different feeding behaviours of the hosts. Intensities of Anisakis sp. in A. carbo were high irrespective of sex and season. No relationship between host length and prevalence of infection was observed for A. carbo, while for S. japonicus a weak positive significant relationship was found.

Abstract:
Length-weight relationships are presented for 9 commercial fish species from Psara Island (North Aegean Sea).The species studied are Boops boops, Dentex maroccanus, Helicolenus dactylopterus, Merluccius merluccius, Mullus surmuletus, Pagrus pagrus, Raja clavata, Scyliorhinus canicula and Trachurus picturatus. To our knowledge, there are no published data on the fish stocks of the study area. Estimates of LWR parameters are provided for Dentex maroccanus, Trachurus picturatus and Helicolenus dactylopterus, for which reliable LWR datasets are few in the literature, while none has been published for the Greek seas. The samples were collected from the continental shelf and the upper slope, by using non-selective fishing gear (with a research vessel and a commercial bottom trawler), during two seasonal sampling periods: November 2009 and May 2010.The growth pattern of Boops boops and Scyliorhinus canicula was found to be positive allometric, whereas an isometric growth pattern was determined for the other species in the study. We hope that the LWR obtained here will be used in future fisheries management or conservation research in the study area, for example, to convert lengths to weights, determine fish condition and assess spatial or temporal variability in fish growth.

Abstract:
AbstractBlue jack mackerel,Trachurus picturatus,is a carangid fish which constitutes an important commercial resource in the north-east Atlantic. Its metazoan parasite community from Portuguese mainland waters was investigated here for the first time. Nine parasite taxa were found, most of which are common parasites ofTrachurusspp. The parasite community was broadly similar to that of the Atlantic horse mackerel,T. trachurus, from the same region, but two digenean species were detected in blue jack mackerel,Monascus filiformisandTergestiasp., which did not occur in horse mackerel from this region. A comparison with the two previous studies ofT. picturatusparasite communities shows that continental-shelf regions are characterized by higher prevalences of digenean trematodes and an absence of trypanorhynch cestodes, in contrast with oceanic regions.

Abstract:
In Portugal it has been estimated that unreported catches represent one third of total catches. Herein, information on landings and total unreported catches (discards) by commercial métier were disaggregated into high taxonomic detail using published scientific studies. Fish accounted for 93.5% (115493 t) of overall unreported catches per year, followed by cephalopods (2345 t, 1.9%) and crustaceans (1754 t, 1.4%). Sharks accounted for 1.3% of total unreported catches in weight (1638 t/y). Unreported taxa consisted mostly of the commercial landed fish species: Scomber colias, Boops boops, Trachurus picturatus, T. trachurus, Merluccius merluccius, Sardina pilchardus, Liza aurata and Micromesistius poutassou, which together accounted for 70% of the unreported discarded catches. The number of unreported/discarded species was highest in artisanal fisheries, followed by trawl and purse seine. In artisanal fisheries, L. aurata, S. colias, S. pilchardus, Trachinus draco and B. boops accounted for 76.4% of the unreported discards. B. boops, S. colias and S. pilchardus were also among the most discarded purse seine species, together with Belone belone accounting for 79% of the unreported catches. In trawl fisheries, T. picturatus (16%), M. merluccius (13%), S. colias (13%) and M. poutassou (13%) accounted for 55% of the trawl discarded unreported catches. The discarded species that most contribute to overall unreported catches are those that are most frequently landed and that most contribute to overall landings in weight.

Abstract:
Determina la calidad microbiológica de “jurel” y “choro” procedentes de treinta mercados de los distritos de San Juan de Lurigancho y de San Martín de Porres. Para ello, de cada puesto de mercado se toman muestras de “jurel” y “choro”, a las cuales se les realiza el recuento de aerobios mesófilos y recuento de Staphylococcus aureus según la metodología de ICMSF (2000); asimismo, se determina la numeración de Escherichia coli, la detección de Salmonella sp., Vibrio cholerae y Vibrio parahaemolyticus aplicando la metodología descrita en el FDA/BAM. Los resultados indican que el 56% del total de las muestras analizadas son consideradas “No aptas” para consumo humano; además, se observa que el 17% de las muestras de “jurel” y 63% de las muestras de “choro” superan los límites máximos permitidos establecidos para E. coli. Se aisla Salmonella sp. en el 7% de las muestras de “jurel” y el 20% de las muestras de “choro”. V. cholerae y V. parahaemolyticus no son detectadas en ninguna de las muestras analizadas. Se concluye que la mayor parte de las muestras de “choros” se consideran “No aptas” para consumo humano, constituyendo un riesgo para la salud de los consumidores.

Abstract:
Esta dissertação abordou duas temáticas principais: a identificação da estrutura do stock de chicharro, Trachurus picturatus (Bowdich, 1825), no sul do Atlântico nordeste e o estudo dos parâmetros de história de vida para a população da Madeira. A estrutura do stock de chicharro ainda é desconhecida e para identificar as unidades populacionais, foram selecionadas três áreas, Madeira, Portugal continental e Canárias, e utilizadas várias metodologias: morfologia do contorno do otólito, morfologia do corpo e análise parasitológica. Na primeira, foram analisados 100 otólitos por área, tendo os resultados da análise aos descritores elípticos de Fourier normalizados (NEFDs) revelado diferenças significativas entre as três áreas (classificação geral de 86.3%). Relativamente à morfologia do peixe, a atribuição de espécimes às localizações geográficas em estudo foi classificada corretamente em 80.7% das amostras (K = 0.67). Estes resultados juntamente com o padrão de infeção dos parasitas Anisakis spp., Rhadinorhynchus sp. e Nybelinia sp. confirmaram a distinção de 3 unidades populacionais no sul do Atlântico nordeste. Nos parâmetros de história de vida, a idade foi determinada a partir de 1405 espécimes, colhidos entre 2009 e 2010. A verificação das leituras foi efetuada segundo a análise do incremento marginal e a evolução mensal do tipo de bordo. Os resultados mostraram a existência de dois anéis por ano, tendo sido atribuídos sete grupos de idade (0-6). Não se verificaram diferenças significativas entre sexos nos comprimentos médios à idade e nas curvas de crescimento de von Bertalanffy. Os parâmetros de crescimento estimados foram: L∞ = 27.98 cm, k = 0.266 ano-1 e t0 = -2.713 ano. A relação peso-comprimento estimada para todos os indivíduos foi de Wt = 0.00411Lt3.230. A época de desova estendeu-se de janeiro a abril. A espécie atinge a maturidade sexual no primeiro ano com comprimentos de 17.06 e 17.04 cm para fêmeas e machos respetivamente.
This thesis addressed two main themes: the identification of the stock structure of blue jack mackerel, Trachurus picturatus (Bowdich, 1825), in the South Atlantic Northeast and the study of life history parameters for the Madeira population. The stock structure of blue jack mackerel is still unknown, and to identify the populational units, three areas were selected, Madeira, mainland Portugal and the Canary Islands, and used different methodologies: otolith morphometry, body shape morphometry and parasitological analysis. For the first methodology, 100 otoliths were analysed by area, and the results of the analysis made to elliptical Fourier descriptors (NEFDs) shown significant differences among the three areas (overall rating of 86.3%). Regarding the body shape morphometry, assigning specimens to the geographic locations under study were correctly classified in 80.7% of the samples (K = 0.67). These results along with the pattern of infection of the parasites Anisakis spp., Rhadinorhynchus sp. and Nybelinia sp. pointed to the existence of 3 stocks in the South Atlantic Northeast. In life history parameters, age was determined on 1405 specimens collected between 2009 and 2010. Otolith reading verification was performed according to marginal increment analysis and monthly analysis of otoliths edge type. The results confirmed the presence of two rings per year, being allocated seven age groups (0-6). There was no significant differences between sexes in mean lengths-at-age and in the von Bertalanffy growth curves. The growth parameters estimated were: L∞ = 27.98 cm, k = 0.266 year-1 and t0 = -2.713 year. The length-weight relationships for sexes combined was Wt = 0.00411Lt3.230. The spawning season extended from January to April. The species reaches sexual maturity in the first year (0.69 year, females and males) with total length of 17.06 cm for females and 17.04 cm for males.
