Age and Growth of the lemon sole (Microstomus kitt) in the Celtic Sea and the North Sea ArchiMer
Mahe, Kelig; Elleboode, Romain; Persohn, Cecile; Dufour, Jean-louis.
Age and growth of lemon sole (Microstomus kitt) were determined from 115 specimens collected in the Celtic Sea and in the North Sea in 2006 and 2007. Total length is ranged from 11 to 44 cm, while total weight varied between 12 and 1040 g. Age estimation was based on otoliths readings. The oldest male and female were estimated to be 9 years old. The length–weight relationships parameters for lemon sole in the Celtic Sea and in the North Sea were W=0.0043*TL3.2860 and W=0.0062*TL3.1505 respectively. Weight including both sexes increased with positive allometric growth. The von Bertalanffy growth equation in the North Sea was fitted on the basis of mean length-at-age data resulting in parameters values of TL∞ = 36.44 cm (S.E. = 0.484), K = 0.187 /y (S.E. =...

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...

Ageage des buccins (Buccinum Undatum L) de la cote Ouest-Cotentin (France) à partir des statolithes ArchiMer
Cochard, Marie-laure; Elleboode, Romain; Mahe, Kelig.
La baie de Granville dans le golfe normano-breton, située en Manche Est, représente la principale région française et européenne de pêche du buccin (Buccinum undatum) et génère une activité économique importante (environ 8000 tonnes et 12 millions € par an). Cette pêcherie est exploitée par 50 à 60 caseyeurs (arts dormants). Elle est très encadrée réglementairement (licences, quotas journaliers, taille minimale de capture). Bien que la production estimée soit relativement stable ces dernières années, la pêcherie reste vulnérable car localisée dans la partie méridionale de l’aire de répartition de l’espèce et pourrait être impactée défavorablement par un réchauffement climatique (Cf. derniers scenarii du GIEC). En ce sens, le buccin pourrait constituer une...

Analyses sclérochronologiques d’écailles archéologiques d’ombres commun Thymallus thymallus et inférences sur la pêche paléolithique au Taillis des Coteaux (Vienne, France) ArchiMer
Guillaud, Emilie; Elleboode, Romain; Bearez, Philippe; Mahe, Kelig.
Lors des fouilles archéologiques du Taillis des Coteaux, plus de 791 écailles ont été mises au jour dans une zone attribuée chronologiquement au Magdalénien inférieur. L’origine (animale ou anthropique) des accumulations de poissons dans les sites archéologiques est souvent méconnue. L’application de la sclérochronologie à l’étude de ces restes nous permet non seulement d’avoir une estimation de l’âge du poisson, mais aussi de préciser la période de capture. La connaissance de la saison de mort des individus est un bon indicateur des activités humaines et/ou d’autres prédateurs (carnivores, oiseaux). La majorité des écailles est attribuable aux salmonidae. Parmi les espèces identifiées, seul l’ombre commun Thymallus thymallus (L., 1758) est bien...

Are red mullet efficient as bio-indicators of mercury contamination? A case study from the French Mediterranean ArchiMer
Cresson, Pierre; Bouchoucha, Marc; Miralles, F.; Elleboode, Romain; Mahe, Kelig; Marusczak, Nicolas; Thebault, Herve; Cossa, Daniel.
Mercury (Hg) is one of the main chemicals currently altering Mediterranean ecosystems. Red mullet (Mullus barbatus and M. surmuletus) have been widely used as quantitative bio-indicators of chemical contamination. In this study, we reassess the ability of these species to be used as efficient bio-indicators of Hg contamination by monitoring during 18 months Hg concentrations in muscle tissue of mullet sampled from 5 French Mediterranean coastal areas. Mean concentrations ranged between 0.23 and 0.78 μg g−1 dry mass for both species. Values were consistent with expected contamination patterns of all sites except Corsica. Results confirmed that red mullets are efficient bio-indicators of Hg contamination. Nevertheless, the observed variability in Hg...

Blue whiting otoliths pair’s symmetry side effect ArchiMer
Gonçalves, Patricia; Mahe, Kelig; Elleboode, Romain; Chantre, Celina; Murta, Alberto; Avila De Melo, Antonio; Cabral, Henrique.
Otoliths are paired calcified structures located in the inner ear of the teleost fishes. Fisheries scientists have been using the otoliths for a variety of applications as fish ageing, species identification and also species interaction. The symmetry between left and right otoliths is considered species dependent. The application of analysis techniques on otoliths images has been increasing in recent years. The diagnosis on otoliths symmetry as a species characteristic is currently being done. It is expected that the otolith surface (distal versus proximal) used to collect images should have no influence on the symmetry results. The goal of this study is to investigate if the otolith position (distal versus proximal) when analyse images has influence in...

Comparing growth in surface and cave morphs of the species Astyanax mexicanus: insights from scales ArchiMer
Simon, Victor; Elleboode, Romain; Mahe, Kelig; Legendre, Laurent; Ornelas-garcia, Patricia; Espinasa, Luis; Retaux, Sylvie.
Background Life in the darkness of caves is accompanied, throughout phyla, by striking phenotypic changes including the loss or severe reduction in eyes and pigmentation. On the other hand, cave animals have undergone constructive changes, thought to be adaptive, to survive in this extreme environment. The present study addresses the question of the evolution of growth in caves, taking advantage of the comparison between the river-dwelling and the cave-dwelling morphs of the Mexican tetra, Astyanax mexicanus. Results A sclerochronology approach was undertaken to document the growth of the species in these two very distinct habitats. Scales from 158 wild Astyanax mexicanus specimens were analyzed from three caves (Pachón, Tinaja and Subterráneo) and two...

Comparison between the opercular bones, the scales and the otoliths to investigate the growth of the brilliant pomfret (Eumegistus illustris) off the coast of Reunion Island (SW Indian Ocean) ArchiMer
Mahe, Kelig; Rabhi, Khalef; Bellamy, Elise; Elleboode, Romain; Aumond, Yoann; Huet, Jerome; Roos, David.
The brilliant pomfret (Eumegistus illustris) occurs in the western part of the Indian Ocean and the western and central Pacific Ocean. To date, the biology of E. illustris has never been documented. The aim of the present study was to investigate age and growth of E. illustris along the coasts of Reunion Island, based on calcified structures analysis. One hundred thirty five individuals were sampled in the landings of the French local artisanal fisheries from March 2014 to March 2015. The relationships between two types of body length (Total and Standard lengths, cm) and Total weight (g) were significant (P<0.05). Total length-weight relationship was described by the following parameters: a=0.012 and b=3.015 without significant effect of sexual...

Croissance des juvéniles du merlu (Merluccius merluccius) des eaux septentrionales de la Tunisie à partir de l'analyse des microstructures des otolithes ArchiMer
Khoufi, Widien; Elleboode, Romain; Jaziri, Héla; El Fehri, Safouène; Bellamy, Elise; Ben Meriem, Sadok; Romdhane, Mohamed; Mahe, Kelig.
Hake (Merluccius merluccius) is widely distributed in the Atlantic Ocean and the Mediterranean Sea. It is one of the most exploited demersal fish. In Tunisia, hake is captured from the north to the south (KHOUFI et al., 2010). Hake is an important species of economic interest and thus the subject of a large literature, but its biology remains insufficiently known, particularly on terms of age and growth estimations, which are essential for stock assessment and management. Otolith microstructure provides a useful tool for age determination of juvenile hake, based on daily increment deposition (ARNERI & MORALES-NIN, 2000; MORALES-NIN et al., 2005; KACHER & AMARA, 2005; BELCARI et al., 2006). Consequently, we studied growth and estimated age, using...

Directional bilateral asymmetry in otolith morphology may affect fish stock discrimination based on otolith shape analysis ArchiMer
Mahe, Kelig; Ider, Djamila; Massaro, Andrea; Hamed, Oussama; Jurado-ruzafa, Alba; Goncalves, Patricia; Anastasopoulou, Aiketerini; Jadaud, Angelique; Mytilineou, Chryssi; Elleboode, Romain; Ramdane, Zohir; Bacha, Mahmoud; Amara, Rachid; De Pontual, Helene; Ernande, Bruno.
Otolith shape analysis is an efficient fish stock identification tool. However, most applications used left and right otoliths or only one of them arbitrarily chosen without testing for biases resulting from potential directional bilateral asymmetry (DA) in otolith shape, i.e. a unimodal population-level deviation form bilateral symmetry between right and left otolith shapes. In this study, 560 bogues (Boops boops) were sampled from 11 geographical locations from the Canary Islands to the Aegean Sea and elliptical Fourier descriptors were used to describe their otoliths’ shape. First, a significant otolith DA was observed at the global scale with an average amplitude of 2.77%. However, at the scale of sampling locations, DA was not always significant and...

Estimation de la croissance journalière de juvéniles de poissons à partir des microstries observables à la surface des otolithes : cas de la plie et de la sole en Manche Est, du maigre dans le golfe de Gascogne et du merlu dans le golfe du Lion ArchiMer
Mahe, Kelig; Elleboode, Romain; Bellamy, Elise.
Chez les poissons, l’âge est estimé à partir de l’analyse de pièces calcifiées (écaille, otolithe, vertèbre…). L'otolithe, situé dans l'oreille interne, est le plus utilisé en écologie car il est métaboliquement inerte et sa croissance est continue tout au long de la vie du poisson. Chaque poisson présente 3 paires d'otolithes (sagitta, lapillus et astericus) et leur forme sont différentes et spécifiques à chaque espèce. Le dénombrement des couches concentriques successives présentes sur les pièces calcifiées permettent d'estimer l'âge et la croissance somatique du poisson. Cependant, ces structures à la surface de l'otolithe peuvent présenter des échelles temporelles différentes. Chez les juvéniles, l'analyse des accroissements primaires traduit une...

Estimation of Age, Growth and Fishing Season of a Palaeolithic Population of Grayling (Thymallus thymallus) Using Scale Analysis ArchiMer
Guillaud, Emilie; Elleboode, Romain; Mahe, Kelig; Bearez, Philippe.
The fish remains sampled from archaeological sites are generally the result of human food refuse; therefore, the study of retrieved fish scales may provide reliable information on the season of capture and on paleoclimate and paleoenvironmental changes. Among Western European freshwater fishes, the grayling, Thymallus thymallus¸ has the most easily recognizable scales and is a commonly recovered species from Paleolithic contexts. This study, therefore, is based on the growth pattern analysis of modern and archaeological scales from grayling specimens. The modern specimens were collected monthly in France (n = 22), Switzerland (n = 16), Finland (n = 20) and Sweden (n = 10). Scale growth patterns were measured using numerical analysis to a high accuracy. The...

Etude de la croissance des espèces profondes de l’île de la Réunion ArchiMer
Rabhi, Khalef; Bellamy, Elise; Elleboode, Romain; Roos, David; Aumond, Yoann; Huet, Jerome; Mahe, Kelig.
Ces dernières années, la petite pêche réunionnaise qui ciblait traditionnellement les espèces récifales et démersales peu profondes, a évolué progressivement vers l’exploitation des stocks de poissons plus profonds (au-delà de 200 m). Ces nouvelles espèces économiquement importantes font l’objet d’une forte exploitation mais sont cependant fragiles d’un point de vue biologique (croissance lente, maturité sexuelle tardive, recrutement aléatoire, écosystème sensible, habitats restreint à La Réunion). Ainsi, il y a une nécessité de mettre en place des mesures de gestion rationnelles et durables de ces ressources. Pour répondre à cela, le projet de recherche DMX (Indicateurs biologiques et écologiques pour une gestion durable des stocks de poissons DéMersauX...

The uncertainty in age estimation by otolith reading may be at the root of the large variability in red mullet (Mullus barbatus) growth models in the Mediterranean. In the MEDITS survey, red mullet age data are produced following the same sampling protocol and otolith reading methodology. However, ageing is assigned using different interpretation schemes, including variations in theoretical birthdate and number of false rings considered, in addition to differences in the experience level of readers. The present work analysed the influence of these variations and the geographical location of sampling on red mullet ageing using a multivariate approach (principal component analysis). Reader experience was the most important parameter correlated with the...

First record of Dadylopterus volitans (Dactylopteridae) in the Eastern English Channel ArchiMer
Mahe, Kelig; Foucher, Eric; Elleboode, Romain; Iglesias, Samuel; Tetard, Alain.
The family Dactylopteridae comprises seven valid species mostly distributed in tropical and subtropical seas (Eschmeyer and Fong, 2013). The flying gurnard Dactylopterus volitans (Linnaeus, 1758) is present in the Eastern Atlantic, apparently from the North Sea to Angola, including the entire Mediterranean Sea and the Azores, and in the Western Atlantic, from Canada to Argentina (Froese and Pauly, 2013). It is the only species of the family Dactylopteridae present in the European Atlantic (from 36 degrees N to 66 degrees N) (Roux, 1986; Quero et al., 2003). The point map of D. volitans given in FishBase (Froese and Pauly, 2013) showed a single record in the Bay of Biscay and a single record point in the Southern North Sea, although the latter seems to be...

Growth estimation of Merluccius merluccius off the northern coast of Tunisia ArchiMer
Khoufi, Widien; Dufour, Jean-louis; Jaziri, Hela; Elfehri, Safouene; Elleboode, Romain; Bellamy, Elise; Ben Meriem, Sadok; Romdhane, Mohamed Salah; Mahe, Kelig.
Growth parameters of any species are fundamental for biological or dynamic studies. The quality of the estimation for these parameters directly impacts on species stock assessment and, as a consequence, on fisheries management. In order to improve fishery and species stock management, growth analysis, especially by sex, is recommended. In this study, otoliths were used to estimate growth parameters of Merluccius merluccius Rafinesque, 1810. Hake is well-known as being a species in which otolith interpretation is extremely difficult. To estimate growth parameters, the first daily increment was validated as the tool for age determination. Otolith interpretation was done according to the last results of ICES cooperative research report. In total, a sample of...
