Abstract:
Abstract The parasitic copepod, Lernanthropinus trachuri (Brian, 1903) (Copepoda, Siphonostomatoida, Lernanthropidae)was found on the Mediterranean horse mackerel, Trachurus mediterraneus in Bandırma Bay, Turkey. The aim of this study is to present female Lernanthropinus trachuri with morphological characters with photos from Turkey. The details unseen in photos were supported with drawings. All parasites were firmly attached to the gill filaments of the host. This parasite is also specific for the genus Trachurus (Costa et al 2017). Therefore, this parasite may use as biomonitor or tag species for fish stock studies in Turkey.

Abstract:
AbstractAnisakis is a parasite of marine mammals that uses a great number of fish species as intermediate or paratenic hosts. It is common in commercially important marine fishes and its presence is of great concern for both human health and economic reasons. Horse mackerels (Trachurus trachurus) originated from the Northern Aegean Sea were examined for the presence of Anisakis spp. larvae. The prevalence of Anisakis spp. was found 98.8 %. The number of parasites was significantly related to the host’s length but was not related to the fish gender. The month of sampling affected the size of the fishes and consequently the number of parasites. The length of larvae was not related to the host’s length. The present study resulted in the design of a prediction model for the number of existing parasites in the fish by measuring only its Fixed Length.

Abstract:
Trachurus trachurus, is a migratory, semi-pelagic species of the Carangidae family living in schools often associated with mackerel. This species is very common in the Mediterranean, and it is found on all Moroccan coasts. This study aims to determine the length-weight relationship and the condition factor (K) of Trachurus trachurus. Thus, 390 specimens were collected between August 2017 and August 2018 in the central-east region of the Moroccan Mediterranean. The parameters of the length-weight relationship were determined and analyzed by length and sex. It appears that this species has better growth in length than in weight, therefore having a negative or lower allometry. It varies according to sex, length, and season. This result shows that Trachurus trachurus in this study is not overweight in its habitat.

Oocyte development in captive Atlantic horse mackerel Trachurus trachurus. – ICES Journal of Marine Science, 66: 623–630. This 13-month experimental study focused on developing oocyte production in 101 adult female Atlantic horse mackerel. In addition, proxies of energy patterns in relation to oocyte development were investigated. The fish were captured off western Norway and fed to satiation from October 2005 to November 2006 in two replicate adjacent circular tanks. Monthly histological examination of the ovaries indicated that vitellogenic oocytes were present at all times throughout the study period, but that oocyte development did not progress past the incipient migratory nucleus stage. The oocyte diameter (OD) threshold between pre-vitellogenic and vitellogenic oocytes and the mean OD of the leading cohort were investigated, and no hiatus was observed within the OD size distribution around the 185-µm pre-vitellogenic and vitellogenic threshold. Variation in gonadosomatic index, hepatosomatic index, condition factor, and fat content (as measured by the use of a Distell Fish Fatmeter) increased with oocyte development. The observed development of oocyte recruitment and the absence of a hiatus in the oocyte distribution are characteristics of an asynchronous spawner. The species seems to have a prolonged spawning season, judging from the advanced and variety of maturity stages throughout the study period.

Abstract:
The study was carried out to assess the microbiological quality of smoked Trachurus trachurus and Scomber scumbrus in four markets in Orlu Local Government Area, South East, Nigeria. Forty freshly smoked samples of Trachurus trachurus and Scomber scumbrus were procured from Eke Eziachi, Orlu Main, Aforaja Umuowa and Afor Ogidi Ihioma markets and analyzed using standard techniques. Results revealed that Orlu main market had the highest level of microbial contamination (mean bacteria and fungi count of 5 x 102 and 10 x 102cfu/g respectively). The highest total viable count (7 x102 cfu/g) of Scomber scumbrus was obtained in Aforaja Umuowa market while the least value of 2 x102 cfu/g was observed in Afor Ogidi Ihioma market. Also, similar value was recorded in Trachurus trachurus at Aforaja Umuowa market. Results from the study indicated that pathogens present in fish samples included bacteria (Bacillus cereus, B. subtilis, Escherichia coli, Salmonella spp and Staphylococcus aureus) and fungi (Gliocladium spp., Candida spp., Rhizopus spp., Alternaria spp., Aspergillus spp., Clasdosprium spp., Fonsecaca spp., Chrysoporius spp., mucour spp. and Botrytis spp). The study also showed that freshly smoked Trachurus trachurus and Scomber scumbrus samples sold in the four markets under assessment were contaminated with pathogenic organisms. This may however present some public health implications. Keywords: Microbial activity, Smoked fish, Orlu, Fish quality; Hygiene

Abstract:
Three stocks of the Cape horse mackerel, Trachurus trachurus capensis, have been recognised in the ICSEAF convention region off southern Africa (Figure 1) on the basis of catch distribution and biological analyses. They were identified as being off Namibia (ICSEAF Divisions 1 . 3 and 1.4), off the West Coast of South Africa (Div. 1.6) and off the South Coast (Div. 2.1 and 2.2). Recently, speculation as to the accuracy of the classification of the South African populations has arisen. The aim of this study was to determine the number of stocks In Divisions 1.6, 2.1 and 2.2, using methodology which assessed the spatial and temporal nature and the phenotypic and genotypic characteristics of the species. The distribution of horse mackerel was evaluated by studying the trends in catch data and length frequency distributions obtained from the demersal industry during 1986 to 1988 and from the demersal biomass cruises in 1987 and 1988. Adult fish, found in Div. 2.1 and 2.2, probably migrated; during the months in which horse mackerel were expected to spawn, CPUE values were higher over the central Agulhas Bank than in the east of the study region. During the quiescent period, catches and numbers were higher in the latter region. Juvenile horse mackerel were found in the nursery areas utilised by pelagic fish and it is likely that they were transported northward from the Agulhas Bank. A decrease in biomass of individuals in Div. 1.5 indicated a separation between a northern and a southern population. Analyses of the phenotype, or epigenetic characters, of horse mackerel were used as a further test of stock integrity. Monthly samples were drawn from Div. 1.6, 2.1 and 2.2 during May 1988 to June, 1989. Comparisons for the values obtained from growth, length-at-50%-maturity and the season of otolith ring formation from each region showed no significant variation in the phenotype. Morphometric analysis proved inconclusive. Monthly gonadosomatic indices show that fish south of the Orange River share the same spawning season. Reports from the literature show that horse mackerel in the latter region differ from those of northern Namibia in spawning season, age-at-50%-maturity and season of otolith ring formation. The genetic structure of the populations of horse mackerel was evaluated by means of a restriction enzyme analysis of the Mitochondrial DNA of 37 fish collected from Divisions 1.4, 1.5, 1.6, 2.1 and 2.2. Two composite genotypes of horse mackerel were found; one belonging to fish in Div. 1.4 and one to fish in Div. 1.6, 2.1 and 2.2. The genetic distance between the two genotypes, 0.07, was the expected distance between two populations at a subspecies level. Fish in Div. 1.5 consisted of both genotypes and may be a region of mixing between the two populations. The interpretation of results was cautioned; prevlous work has shown that the migration of a small number of individuals between two stocks can be expected to maintain a low variation between the populations. In concluding, it was recommended that the horse mackerel be managed as two stocks, one in Div. 1.3 and 1.4 and one in Div. 1.6, 2.1 and 2.2

Abstract:
Le chinchard, Trachurus murphyi constitue une espèce importante pour la pêcherie dans le sud-est de l'océan Pacifique. Dans cette thèse, la morphologie des ovocytes atrétiques, prévalence et l'intensité de l'atrésie ont été décrits. Les stades d'atrésie identifiés sont les stades alpha, bêta et gamma. Les modèles linéaires généraux ont montré que l’incidence des follicules pot-ovulatoires, la température de surface de la mer et le facteur mois/année, expliquent la prévalence et l'intensité. La dynamique des stades alpha et bêta-atrésie pourrait être considérée comme un indicateur potentiel de toute perturbation de la saison de frai de cette espèce. Cette étude constitue une première évaluation comparative de la fécondité entre les femelles atrétiques et non atrétiques pour cette espèce.La fécondité partielle et la fécondité relative sont inférieures à celles observées chez d’autres espèces de Trachurus. T. murphyi, la base de données transcriptomique (tissus du foie et des ovaires) a été générée. Cette étude a notamment permis d’identifier quelques marqueurs plus spécifiques de l'atrésie comme des protéines de liaison aux acides gras (FABP) et de la follistatine. L'analyse transcriptomique a démontré l'expression de gènes potentiellement associés à une infection par des protozoaires.L’ensemble du foie de T. murphyi est parasité par Goussia cruciata (Apicomplexa).L'abondance du parasite était corrélée négativement à la longueur totale de l'hôte. Une relation potentielle entre l’infection par les protozoaires et l’atrésie ne peut être établie
The Chilean jack mackerel Trachurus murphyi support an important fishery in the South-eastern Pacific Ocean which has declined considerably over time. In this thesis, morphology of atretic oocytes in T. murphyi as well, patterns of prevalence and intensity of atresia were described. The stages of atresia identified were alpha, beta and gamma. General linear models showed that incidence of postovulatory follicles, sea surface temperature and month/year, explain the prevalence and intensity of atresia. Dynamics of alpha and beta-atresia could be considered a potential proxy for any disruption of spawning season and the end of spawning season. This is the first assessment comparing fecundity between atretic and not atretic females.The batch fecundity and relative fecundity were lowest compared with other species of Trachurus. In T. murphyi, the transcriptomic database (liver and ovary tissue) was generated. The results show a set of core potential genes as markers for atresia as fatty acid-binding protein (FABP) genes and follistatin. The transcriptomic analysis demonstrated the expression of genes associated to protozoan infection. All liver of T. murphyi were parasitized by Goussia cruciate (Apicomplexa), the abundance of the parasite was negative correlated with the host total length. A potential relationship between protozoan infection and atresia cannot be established

Abstract:
This study investigates the population biology of horse mackerel inhabiting the Northeast Atlantic, their spawning grounds and migrations, and the degree of stock separation, with emphasis on the Southern and Western areas of the European shelf. The investigations involved the use of a wide range of methodologies and techniques, including age determination techniques, tagging experiments, the analysis and evaluation of commercial catch data, egg survey data, bottom trawl survey data, biochemical methods, morphometric methods, survey sampling methodology, and associated statistical analysis. Multivariate analysis of morphometric measurements, indicate that the horse mackerel that spawn on the Portuguese shelf (Southern area) are distinct from those that spawn on the Irish shelf (Western area). A distinction can also be made between the Portuguese horse mackerel and those from the Celtic Sea, English Channel and Northern Bay of Biscay. These findings are further supported by a study of otolith first ring distance, which also indicates that the Western and the North Sea horse mackerel are not significantly different from each other. Growth parameters of horse mackerel from the Western and Southern areas were estimated using length and age data and the resulting growth curves for the two areas are different. This result is primarily due to differences in the growth of the younger fish. In the Southern area the fish grow faster than in the Western area. These results provide evidence for the existence of a separate unit stock of horse mackerel off the Portuguese coast, which is reproductively distinct from other populations in the north-east Atlantic. The results froma study of plasma transferrin polymorphisms did not provide any evidence in support of these findings. The population structure and stock separation of horse mackerel in the north-east Atlantic are described and the implications for future management are discussed

Anisakis spp. é considerado um dos mais importantes perigos parasitários dos produtos da pesca na medida em que é responsável pela anisaquiose. Esta zoonose, cujos efeitos gastrointestinais e alérgicos podem ter graves consequências para o ser humano, ocorre quando peixes ou cefalópodes parasitados são ingeridos crus ou confecionados de forma deficiente. Em consequência da sua omnipresença nas principais famílias de peixes e cefalópodes com interesse comercial, tornou-se imperioso o estabelecimento de criteriosas regulamentações. Para se conhecer melhor a realidade portuguesa neste aspeto foi escolhido o carapau (Trachurus trachurus) para efetuar um estudo de ocorrência, intensidade e abundância parasitárias assim como uma caracterização morfométrica dos parasitas do género Anisakis encontrados. Dos 104 exemplares de peixe provenientes da lota de Peniche foram recolhidas 1 504 larvas tanto das vísceras como do músculo. Foi detetada uma positividade global de 67,31% e a intensidade e abundância médias foram, respetivamente, de 21,48 e 14,46. Das larvas do género Anisakis recolhidas 96,61% correspondiam ao tipo I (sensu Berland, 1961). Atualmente, diversas técnicas moleculares são utilizadas na identificação das distintas espécies deste género parasitário como forma de caracterizar mais rigorosamente a sua ecologia e obter dados epidemiológicos mais precisos que resultem na prevenção mais eficaz desta zoonose.
ABSTRACT - Anisakis spp. is considered one of the most important parasitic hazards in fishery products. Being responsible for the zoonosis named anisakiasis, this nematode can cause severe gastrointestinal and allergic effects on consumers when seafood is ingested raw or undercooked. Additionally, it infects most families of commercially relevant fish and squid, generating the urge to regulate this sector through thorough legislation. In order to further understand the situation in Portugal, it was chosen the Atlantic horse mackerel (Trachurus trachurus) to study some aspects of its relationship with the genus Anisakis in terms of parasitic frequency, intensity and abundance as well as to execute a morphometric analysis of the larvae found. Of the 104 fish specimens collected in Peniche, 67.31% harboured a total of 1 504 anisakids both in the viscera and muscle. Mean intensity and abundance were 21.48 and 14.46 (respectively) whereas Anisakis type I larvae (sensu Berland, 1961) represented 96.61% of the total number of worms analized. Currently several molecular techniques are performed to identify the different species integrated in this genus as a way to more accurately characterize their ecology as well as to obtain more exact epidemiologic data in order to prevent this zoonosis more effectively.

Dissertação de Mestrado Integrado em Medicina Veterinária
As larvas de terceiro estádio (L3) das famílias Anisakidae e Raphidascarididae são parasitas com potencial zoonótico que são encontrados com muita frequência nas vísceras e musculatura de vários peixes. Como tal, é crucial o conhecimento sobre a prevalência e a distribuição destes parasitas nos peixes com importância comercial, assim como efetuar uma identificação precisa das espécies de anisaquídeos presentes, pois cada espécie tem um diferente grau de patogenicidade para a saúde humana e animal. Existem já vários estudos publicados em revistas com revisão por pares onde é realizada a identificação genética de vários anisaquídeos encontrados em peixes capturados em águas portuguesas. Contudo, que seja do conhecimento dos autores do presente trabalho, este é o primeiro estudo nacional que correlaciona morfometria com análise molecular subsequente das mesmas L3 de A. simplex (s.s.) e A. pegreffii. Uma vez que estas duas espécies são as mais frequentemente associadas a casos humanos de doença e, embora a identificação com recurso a técnicas moleculares seja o ideal, nem sempre é possível executar esse tipo de técnicas, motivo pelo qual neste trabalho se conjuga as duas técnicas de forma a contribuir para que a distinção com base em características morfológicas seja mais fácil. No presente estudo, 116 carapaus (Trachurus trachurus) capturados em águas portuguesas foram analisados quanto à presença de L3 de anisaquídeos, tendo sido colhidas no total 3148 larvas. Dentro desse total de L3 obtidas, apenas 30% foram colhidas durante a inspeção visual dos peixes, o que demonstra que esse método é pouco eficaz na deteção destes parasitas. Foi encontrada uma prevalência de 84,5% de peixes infetados e a intensidade e abundância média foram, respetivamente, de 32,1 e 27,1 parasitas por hospedeiro. A caraterização morfológica e identificação molecular de 196 L3 escolhidas aleatoricamente a partir da amostra total de parasitas revelou a presença de apenas uma L3 de Hysterothylacium aduncum, sendo as restantes L3 de Anisakis spp. Obteve-se uma frequência relativa de 62,9% de A. pegreffii e 37,1% de A. simplex (s.s.). Entre estas duas espécies crípticas, os resultados da análise da morfometria revelaram que existem diferenças significativas entre o comprimento do ventrículo e o comprimento do esófago, podendo estas medidas ser utilizadas para distinguir ambas as espécies na análise morfológica.
ABSTRACT - Anisakidae and Raphidascarididae: A morphological and molecular survey in horse mackerel (Trachurus trachurus) caught in Portuguese waters - Third stage larvae (L3) of the Anisakidae and Raphidascarididae families are parasites with zoonotic potential which are very frequently found in the viscera and musculature of several fishes. Consequently, it is crucial to know the prevalence and distribution of these parasites in fish of commercial importance, as well as perform an accurate identification of the species of anisakids that are present since each species has a different degree of pathogenicity for human and animal health. Several studies have already been published in peer review journals where genetic identification of many species of anisakids found in fish caught in Portuguese waters was carried out. However, to the extent of the authors' knowledge of the current work, this is the first national study which correlates morphometry with a subsequent molecular analysis of the same L3 of A. simplex (s.s.) and A. pegreffii larvae. Since these two species are the most frequently linked species to the human disease and, although genetic identification is better, it is not always possible to perform this kind of technique, this research conjugated both techniques, in order to contribute for easier distinction by morphological characteristics. In the present study, 116 horse mackerel (Trachurus trachurus) caught in Portuguese waters were analyzed for the presence of L3 of anisakids, and 3148 larvae were collected. Within that total of retrieved L3, only 30% have been collected during the visual inspection of fish, which shows that is not a very effective method for detecting these parasites. A prevalence of 84,5% of infected fish was observed and the mean intensity and mean abundance were, respectively, 32,1 and 27,1 parasites per fish. The morphological characterization and molecular identification of 196 L3 randomly chosen from the total sample of parasites revealed the presence of just one L3 of Hysterothylacium aduncum, with the remaining being L3 of Anisakis spp. A relative frequency of 62,9% of A. pegreffii and 37,1% of A. simplex (s.s.) was obtained. Between these two sibling species, morphometry analysis results revealed that there are significant differences between the length of the ventricle and the length of the oesophagus, and as such these measurements can be used to distinguish both species in the morphological analysis.

Abstract:
Recently, questions have been raised as to the appropriateness of stock boundaries in the Atlantic horse mackerel (Trachurus trachurus) and the herring (Clupea harengus) in European waters. To this end, 1919 horse mackerel were examined for parasitic infections from samples taken at nineteen sites around Europe. Forty-five species of parasites were recorded, eleven of which are new host records, and one may be a new species. A number of these are suitable for use as biological tags. Results showed a significant degree of separation between fish from the North Sea and Western stocks, based on the relative abundance of the nematodes Aniaskis spp. and Hysterothylacium sp. The endoparasitic fauna of 4033 herring at various life stages from sites to the west of the British Isles, the North Sea, Baltic Sea and northern Norway were examined to obtain information on stock identity, mixing and recruitment patterns in these areas. Results revealed that substantial stock mixing takes place to the west of the British Isles, with fish from a wide area being found together in non-spawning aggregations off the Hebrides. This area is also home at different times of year to two different spawning populations of fish which recruit from nursery grounds in the eastern North Sea and from the west of Scotland. Investigations were made of the usefulness of the ribosomal small sub-unit cytochrome oxidase (I) gene of the parasitic nematode worm, Anisakis simplex s.s., as a tag of host population biology. Results revealed the COI gene to be highly variable, with around 50% of worms sequenced having unique haplotypes. There were no population structures evident from analysis of genetic distances.

Abstract:
Three finfish species frequently caught in the waters of the Gulf of Manfredonia (Apulia, Italy) were studied in order to know how the flesh composition (proximate, fatty acid, macro- and micro- element contents) could be affected by the season effect. The species we examined were European hake (Merluccius merluccius), chub mackerel (Scomber japonicus) and horse mackerel (Trachurus trachurus), which were analysed at the raw state in three catch season and after cooking in two catch season. More precisely, European hake and chub mackerel caught during winter, summer and fall were analysed at the raw state. The composition of the flesh of grilled European hake and chub mackerel was study on fish caught in winter and fall. Horse mackerel of summer and winter catches were analysed both at the raw and grilled state. Furthermore, an overall sensory profile was outlined for each species in two catch season and the relevant spider web diagrams compared. On the whole, two hundred and eighty fish were analysed during this research project in order to obtain a nutritional profile of the three species. One hundred and fifty was the overall number of specimens used to create complete sensory profiles and compare them among the species. The three finfish species proved to be quite interesting for their proximate, fatty acids, macro- and micro-element contents. Nutritional and sensory changes occurred as seasons elapsed for chub and horse mackerel only. A high variability of flesh composition seemed to characterise these two species. European hake confirmed its mild sensory profile and good nutritional characteristics, which were not affected by any season effect.

Abstract:
Polychlorinated biphenyls (PCBs) can still be a problem for the aquatic environment. Fish species are a suitable indicator for the environmental pollution monitoring because they concentrate pollutants in their tissues directly from water. Concentrations of PCBs were measured in marine fish, collected from Bulgarian Black Sea coast in order to monitor the dynamics of these pollutants in 2007, 2010 and 2015. The fish species: goby (Neogobius melanostomus), sprat (Sprattus sprattus sulinus), horse mackerel (Trachurus Mediterraneus ponticus) and grey mullet (Mugil cephalus) were chosen because of their characteristic feeding behavior. The PCBs were determined by gas chromatography system with mass spectrometry detection. The Total PCBs ranged from 93.8 to 513.3 ng/g lipid weight (in grey mullet and goby, respectively). Levels of PCBs in goby and grey mullet decreased in 2010 and 2015. In order to assess the safety of fish as food were calculated TEQ. They are determined by the results of dioxin - like (dl) PCBs. TEQs were calculated from 0.01 to 0.04 pg TEQ/g ww and did not exceed the EC limit of 3 pg TEQ/g ww. The levels of PCBs in fish from Bulgarian Black Sea were comparable to those found in neighboring seas.

Abstract:
In this study, the ecosystem marine water-sediment-biota was investigated and the pollution was assessed. The concentrations of eight elements were determined in marine water, sediments and four fish species collected from Black Sea (Varna), Bulgaria during 2013. Marine water recorded the highest concentrations of Zn (15-22 μg/L), As (1.1–1.2 μg/L) and Pb (0.7-0.8 μg/L) while Zn (31-52 μg/g), Pb (21-29 μg/g) and Cu (20-34 μg/g) and show the highest concentrations in sediments. Water and sediments showed similar spatial distribution patterns for the highest mean values of the different metals. In the analysed fish species, the highest concentration of the metals Cu and Zn were found in Trachurus Mediterrneus (0.42 mg/kg w.w) and in Sprattus Sprattus (12.7 mg/kg w.w), respectively while the heavy metals As and Hg were found with maximum values in Pseta Maxima (3.99 mg/kg w.w and 0.08 mg/kg w.w respectively). The results from this study were compared with our data for a previous period (2004-2006) and they show decrease in the levels of heavy metal.
