Age, growth and mortality of the starry weever Trachinus radiatus Cuvier, 1829 in the Tunisian waters ArchiMer
Hamed, Oussama; Dufour, Jean-louis; Chakroun-marzouk, Nadia; Mahe, Kelig.
Age, growth and mortality of the Starry weever Trachinus radiatus were studied for the first time from 214 individuals collected in the Gulf of Tunis between February 2014 and January 2016. The significant relationship between length-weight was observed for males (a = 0.011, b = 2.992, R2 = 0.981, n = 77) and females (a = 0.010, b = 3.036, R² =0.957, n = 109). Age was estimated by the observation of otoliths transverse thin sections. Age of individuals ranged from 1 to 15 years. The precision was measured by two age estimations from two experts and indicated a good agreement between them (PA = 85.6%, CV = 3.8% and IAPE = 4.1%). The growth parameters of the von Bertalanffy model were TL∞ = 38.41 cm, W∞ = 507.47 g, K = 0.3396 year-1, t0 = 0 year for males...

Etude du vieillissement de composites verre resine en milieu marin ArchiMer
Gutierrez, J; Lelay, F; Hoarau, P.
Evolution of glass fibre-resin composites (polyester, epoxy and vinylester) after 30 years in a marine environment has been anticipated by the compilation of the Naval Construction Direction test results. This study showed that 120 degree C epoxy prepreg, in spite of improved initial performance, was more affected by water environment aging than other composites. Post-curing of epoxy and vinylester composites does not significantly improve resistance to water degradation except in the case of high temperature aging (60-70 degree C).

Age, growth and mortality of the striped seabream Lithognathus mormyrus (Linnaeus, 1758) in the Gulf of Tunis (Central Mediterranean Sea) ArchiMer
Khaldi, Asma; Chater, Ines; Elleboode, Romain; Mahé, Kelig; Chakroun-marzouk, Nadia.
Despite the high commercial value of the striped seabream Lithognathus mormyrus (Linnaeus, 1758) in the Gulf of Tunis, biological data on its age, growth and exploitation rate are lacking. With the aim of estimating growth parameters, 516 individuals, ranging from 6–27.5 cm total length and from 3.5–293.5 g total weight, were collected from the artisanal fishing fleet between February 2014 and July 2016. The somatic growth presented a positive allometry and was described by the equation TW = 6.54 10−3TL3.213. The monthly analysis of the marginal increment of the otoliths revealed that only one annulus was deposited per year. The estimated von Bertalanffy growth parameters were: L∞ = 30.18 cm, k = 0.303 year−1 and t0 = −1.42 years. Total and natural...

Biological and ecological factors related to trace element levels in harbour porpoises (Phocoena phocoena) from European waters ArchiMer
Lahaye, V; Bustamante, Paco; Law, J.r; Learmonth, J.a; Santos, M.b.; Boon, J.p.; Rogan, E; Dabin, W; Addink, M.j.; Lopez, A; Zuur, A.f.; Pierce, G.j.; Caurant, Florence.
Selected trace elements (Cd, Cu, Hg, Se, Zn) were measured in the kidneys and the liver of 104 harbour porpoises (Phocoena phocoena) stranded along the coasts of France, Galicia (Spain), Ireland, Scotland (UK), and the Netherlands. Generally, relatively low concentrations of toxic elements were encountered in the tissues of European porpoises, except for two individuals, which displayed high hepatic Hg concentrations. Also, elevated Cd levels obtained in Scottish porpoises could be related to their feeding preferences and this result suggests an increase of the proportion of cephalopods in their diet with latitude. Moreover, significant geographical differences were seen in hepatic Zn concentrations; the elevated Zn concentrations displayed by porpoises...

Growth of an Inshore Antarctic fish, Trematomus newnesi (Nototheniidae), off Adelie Land ArchiMer
Mahe, Kelig; Elleboode, Romain; Loots, Christophe; Koubbi, Philippe.
Dusky rockcod, Trematomus newnesi, is a widely distributed neritic circumpolar Antarctic fish species. We conducted a study on age and growth of Trematomus newnesi in coastal waters of Adélie Land in East Antarctica. A total of 289 specimens were collected in 2003, 2005, 2006 and 2009. They consisted of 122 females, 132 males and 35 immature specimens. Total length (TL) and total weight (W) of these fish ranged from 13.5 to 25 cm and 19.7 to 174 g respectively for females and from 12 to 20.9 cm and from 24.1 to 144.1 g for males. The TL/W relationship was described by the following parameters: a=7.2.10-3 and b=3.127, showing no significant difference between sex (ANCOVA, P<0.05). Fish age was estimated by counting annual growth increments on polished...

Age and growth of the striped seabream, Lithognathus mormyrus (Actinopterygii: Perciformes: Sparidae), in the central coast of Algeria, Mediterranean Sea ArchiMer
Boufersaoui, Samira; Kassar, Abderrahmane; Mokrane, Zakia; Elleboode, Romain; Mahe, Kelig.
Background. Striped seabream, Lithognathus mormyrus (Linnaeus, 1758), is a bony fish, which has a high economic value on the Algerian coast. Because of the increasing fishing pressure, however, a close monitoring is recommended. The information about the biology of this species, occurring in the south-western Mediterranean Sea and especially in the north African coast, is very limited. The presently reported study provides new estimated data on age and growth parameters of striped seabream in Algeria. Materials and methods. A total of 449 specimens of L. mormyrus were sampled for 2 years (January 2013 to December 2014) from the commercial fishery in the central part of the Algerian coast. The samples were collected monthly. The fish ranged in size from...

Evidence of underestimation of European hake growth in the Bay of Biscay, and its relationship with bias in the agreed method of age estimation ArchiMer
De Pontual, Helene; Groison, Anne-laure; Pineiro, Carmen; Bertignac, Michel.
In 2002, a pilot experiment on hake tagging was carried out using methodology specifically developed to catch and handle fish in,good condition. By the end of 2005, 36 hake and five tags had been returned to the laboratory (a 3.1% return rate) with a maximum time at liberty of 1066 days. The somatic growth of the recoveries proved to be twofold higher than that expected from published von Bertalanffy growth functions for the species in the Bay of Biscay. The growth underestimation was related to age overestimation, as demonstrated by two independent analyses. The first was based on a blind interpretation of marked otoliths conducted independently by two European experts involved in the routine age estimation of hake. The result shows that the age estimates...

Are hake otolith macrostructures randomly deposited? Insights from an unsupervised statistical and quantitative approach applied to Mediterranean hake otoliths ArchiMer
Courbin, Nicolas; Fablet, Ronan; Mellon-duval, Capucine; De Pontual, Helene.
Individual fish age data are crucial to fish stock assessment, so their accuracy and precision are vital. The acquisition of age data most often relies on interpreting fish otoliths, a complex task in which expert subjectivity increases with the complexity of the structural patterns of the otoliths. The question arises for certain fish species (e.g. hake, Merluccius merluccius) whether the deposition of otolith macrostructures is meaningful for age estimation. A quantitative method based on the evaluation of otolith similarity in terms of structural patterns is presented to investigate this issue. It relies on the determination of a typology of otolith macrostructures from an unsupervised statistical analysis of the distributions of their characteristics....

Size and genotype affect resistance to mortality caused by OsHV-1 in Crassostrea gigas ArchiMer
Degremont, Lionel.
As with summer mortalities reported in France between 2001 and 2006, mortality caused by the Ostreid herpesvirus 1 (OsHV-1) in Crassostrea gigas affects mostly juveniles, although adults can also be impacted to a small extent. This could suggest that both mortalities have similar causes and that establishment of resistance, in particular to the Ostreid herpesvirus 1 (OsHV-1), depends on either the size or the age of oysters. The present study reports an investigation of both size and age using three cohorts produced during winter and three produced during summer. Each cohort contained oysters genetically selected to be resistant or susceptible to the summer mortality phenomenon, as well as unselected control oysters. Any abnormal mortality was recorded...

Estimation de l’âge du merlan (Merlangius merlangus) ? ArchiMer
Dufour, Jean-louis; Chantre, Celina; Elleboode, Romain; Mahe, Kelig.
Le merlan (merlangius merlangus) est une espèce commerciale importante suivie au niveau européen. La pièce calcifiée utilisée pour l’estimation de l’âge du merlan est l'otolithe. Parmi les 3 paires d'otolithes, ce sont toujours les plus gros, les sagittae qui sont utilisés. Ils conservent la séquence complète des marques de croissance enregistrées (Panfili et al., 2002). Pour observer au mieux ces structures, la technique de coupe transversale a été retenue comme la plus précise (ICES WKARWHG2 REPORT 2016). Les images obtenues sont soumises à l’interprétation par les experts européens. Ce rapport propose de décrire précisément les structures observables sur les images obtenues par la technique de coupe transversale. La variabilité des structures est...

Influence de la densite et de l'age des huitres japonaises (Crassostrea gigas ) sur la croissance et la composition biochimique en bassins de terre ArchiMer
Bodoy, A; Geiaron, P; Garnier, Jacqueline; Heurtebise, S.
Two different biomasses (100 g multiplied by m super(-2) and 1 kg multiplied by m super(-2)) of oysters were put in identical sea-water ponds, thus leading to different trophic conditions, corresponding to rearing techniques. Changes in growth, biochemical composition and sexual maturation were recorded for two age groups. The first one included 9 month-old oysters and the second one 21 month-old oysters, at the beginning of the experiment. For both age groups, significant differences were observed in growth and biochemical composition. Lipids were accumulated faster for the lower biomass. However, the only difference concerning glycogen was observed on the older oysters. They showed a peak at the lowest biomass and a decrease at the larger biomass. Sexual...

Ketani,Sennur; Karakoç,Zelal; Ketani,M. Aydin; Kilinç,Mehmet.
ICAM-1 which is expressed by endothelial cells and leukocytes are observed as first markers in diseases such as transplant rejection, diabetes and atherosclerosis and in infections caused by various pathogens. In the present study, it is aimed to reveal the age-related changes in the expression of ICAM-1 on rats. Therefore, a total of 30 albino rats were taken at the age of 6, 18 and 24 months without gender discrimination. Rats were fed with standard pellet feed during the study. Afterwards, rats were sacrificed and tissue samples were collected from their rats, and the samples were evaluated under the light microscope by staining with immnunohistochemical method. It was determined that the expression of both aortic endothelial cells and endothelial cells...

Relationship of the Parietal Foramen and Complexity of the Human Sagittal Suture International Journal of Morphology
Mann,Robert W; Manabe,Jiro; Byrd,John E.
The purpose of this paper is to report on the relationship between the parietal foramen and complexity of the human sagittal suture. Examination of 110 Japanese human skulls (males=67, females=43) with at least one parietal foramen revealed that the sagittal suture in the area of the Obelion was the simplest portion (i.e., fewest interdigitations and shortest length) of the suture (paired t-test, P<0.0005), when compared to the outstretched suture length of three established sections: 1. Parietal foramen section (P); 2. Anterior to section P (B); and 3. Posterior to section P (L). Sutural complexity was also compared between individuals with unilateral foramen (n=48) and bilateral foramina (n=62) to see if there was a statistically significant...

Age Effect in the Morphological Traits Performance for Sex Determination in Human Skulls and Mandibles International Journal of Morphology
Suazo Galdames,Iván; Zavando,Daniela.
In this study we tested the hypothesis that diagnostic performance of the morphological indicators for sexual dimorphism are reduced as they are applied in skull and mandibles of older subjects. We used 275 adult human skulls, 250 of these with mandible, all subjects with sex and age registry. Sixteen classic morphological indicators of sexual dimorphism were evaluated, this information was compared with the registry and results noted in terms of precision. The best general performance of morphological indicators of sexual dimorphism were recorded in the 31 - 40 and 61 - 70 years, age range groups. Lowest precision ws recorded in the group corresponding to subjects between 21 ­ 30 years. Our results do not support the proposed hypothesis and suggest a...

Gontarev,Seryozha; Kalac,Ruzdija; Zivkovic,Vujica; Ameti,Vullnet; Redjepi,Agim.
The success in sport performance is closely related to the physical condition of the sportsman. In the assessment of the physical status except physiological and fitness parameters, significant influence have the anthropometric parameters. The aim of the study was dual: to assess the changes in the anthropometric characteristics and the somatotype of young soccer players at different ages and to compare these characteristics with the general population. The analyzed measurements of 486 young soccer players who play in teams of the First national league, with an average age 15.8±1.4. The soccer players were divided into five subgroups, at age difference of 1 year. In the sample height, weight, BMI index, diameters, volumes and skin folds were measured, also...

The Morphometry of the Angle of Mandible and its Correlation with Age and Sex in the eThekwini Metropolitan Region: A Panoramic Study International Journal of Morphology
Pillay,S; Ishwarkumar,S; De Gama,B.Z; Pillay,P.
The angle of mandible is formed by the tangent line joining the posterior margin of the ramus and the base of the mandible. The angle of mandible has population-specific characteristics therefore; it is imperative to the field of forensic anthropology for age and sex determination. Literary reports regarding the use of the angle of mandible for age and sex determination vary, as some studies support it, while other studies have documented inefficiencies. Therefore, the aim of this investigation was to document the morphometry of the angle of mandible and to determine if a correlation between the angle of mandible, age and sex exists. Sixty four digital panoramic radiographs (n=128) of individuals between 16-30 years were morphometrically analysed using the...
