Activity patterns, home-range size, and habitat utilization of Sarpa salpa (Teleostei : Sparidae) in the Mediterranean Sea ArchiMer
Jadot, Catherine; Donnay, A; Acolas, M; Cornet, Y; Begout, Marie-laure.
Acoustic telemetry was used to record diel movement and habitat utilization of the salema (Sarpa salpa) (Teleostei: Sparidae) during three consecutive summers from 2000 to 2002 in the Calvi and Achiarina bays of Corsica in the Mediterranean Sea. A total of 18 fish was equipped with acoustic transmitters inserted in the body cavity, 13 were tracked in the Bay of Calvi (275 mm +/- 26.9 L-F), and 5 in Achiarina Bay (260 mm +/- 33.6 LF). Two different systems were used to track the fish. The one used in the Bay of Calvi was a manual receiver and a directional hydrophone. The second system, used in Achiarina Bay, was a radioacoustic-positioning (RAP) system that continuously monitored the movements of the fish. Fish positions were put in a geographic...

Allis shad (Alosa alosa) exhibit an intensity-graded behavioral response when exposed to ultrasound ArchiMer
Wilson, M; Acolas, M; Begout, Marie-laure; Madsen, P; Wahlberg, M.
Most fish cannot hear frequencies above 3 kHz, but a few species belonging to the subfamily Alosinae (family Clupeidae) can detect intense ultrasound. The response of adult specimens of the European allis shad (Alosa alosa) to sinusoidal ultrasonic pulses at 70 and 120 kHz is tested. The fish showed an intensity-graded response to the ultrasonic pulses with a response threshold between 161 and 167 dB re 1 mu Pa (pp) for both frequencies. These response thresholds are similar to thresholds derived from juvenile American shad (Alosa sapidissima) in previous studies, supporting the suggestion that these members of Alosinae have evolved a dedicated ultrasound detector adapted to detect and respond to approaching echolocating toothed whales.

A.; Lampert, A.; Kuckelkorn, J.; Grummt, T.; Hollert, H..
The numbers of potential neurotoxicants in the environment are raising and pose a great risk for humans and the environment. Currently neurotoxicity assessment is mostly performed to predict and prevent harm to human populations. Despite all the efforts invested in the last years in developing novel in vitro or in silico test systems, in vivo tests with rodents are still the only accepted test for neurotoxicity risk assessment in Europe. Despite an increasing number of reports of species showing altered behaviour, neurotoxicity assessment for species in the environment is not required and therefore mostly not performed. Considering the increasing numbers of environmental contaminants with potential neurotoxic potential, eco-neurotoxicity should be also...

Assessment of Genetic Variability of Fish Personality Traits using Rainbow Trout Isogenic Lines ArchiMer
Millot, Sandie; Pean, Samuel; Labbe, Laurent; Kerneis, Thierry; Quillet, Edwige; Dupont-nivet, Mathilde; Begout, Marie-laure.
The study of inter-individual variability of personality in fish is a growing field of interest but the genetic basis of this complex trait is still poorly investigated due to the difficulty in controlling fish genetic origin and life history. When available, isogenic lines that allow performing independent tests on different individuals having identical genotype constitute a very relevant experimental material to disentangle the genetic and environmental components of behavioural individuality. We took advantage of heterozygous isogenic lines to investigate the personality in rainbow trout through the analysis of their reactions to different experimental situations. To this end, seven to ten rainbow trout isogenic lines were screened for their spatial...

Changes in Brain Monoamines Underlie Behavioural Disruptions after Zebrafish Diet Exposure to Polycyclic Aromatic Hydrocarbons Environmental Mixtures ArchiMer
Vignet, Caroline; Trenkel, Verena; Vouillarmet, Annick; Bricca, Giampiero; Begout, Marie-laure; Cousin, Xavier.
Zebrafish were exposed through diet to two environmentally relevant polycyclic aromatic hydrocarbons (PAHs) mixtures of contrasted compositions, one of pyrolytic (PY) origin and one from light crude oil (LO). Monoamine concentrations were quantified in the brains of the fish after six month of exposure. A significant decrease in noradrenaline (NA) was observed in fish exposed to both mixtures, while a decrease in serotonin (5HT) and dopamine (DA) was observed only in LO-exposed fish. A decrease in metabolites of 5HT and DA was observed in fish exposed to both mixtures. Several behavioural disruptions were observed that depended on mixtures, and parallels were made with changes in monoamine concentrations. Indeed, we observed an increase in anxiety in fish...

Chronic dietary exposure to pyrolytic and petrogenic mixtures of PAHs causes physiological disruption in zebrafish - part I: Survival and growth ArchiMer
Vignet, Caroline; Le Menach, Karyn; Mazurais, David; Lucas, Julie; Perrichon, Prescilla; Le Bihanic, Florane; Devier, Marie-hélène; Lyphout, Laura; Frere, Laura; Begout, Marie-laure; Zambonino-infante, Jose Luis; Budzinski, Helene; Cousin, Xavier.
The release of polycyclic aromatic hydrocarbons (PAHs) into the environment has increased very substantially over the last decades leading to high concentrations in sediments of contaminated areas. To evaluate the consequences of long-term chronic exposure to PAHs, zebrafish were exposed, from their first meal at 5 days post fertilisation until they became reproducing adults, to diets spiked with three PAH fractions at three environmentally relevant concentrations with the medium concentration being in the range of 4.6–6.7 μg g−1 for total quantified PAHs including the 16 US-EPA indicator PAHs and alkylated derivatives. The fractions used were representative of PAHs of pyrolytic (PY) origin or of two different oils of differing compositions, a heavy fuel...

Chronic dietary exposure to pyrolytic and petrogenic mixtures of PAHs causes physiological disruption in zebrafish—part II: behavior ArchiMer
Vignet, Caroline; Le Menach, Karyn; Lyphout, Laura; Guionnet, Tiphaine; Frere, Laura; Leguay, Didier; Budzinski, Helene; Cousin, Xavier; Begout, Marie-laure.
In the last 10 years, behavior assessment has been developed as an indicator of neurotoxicity and an integrated indicator of physiological disruption. Polycyclic aromatic hydrocarbon (PAH) release into the environment has increased in recent decades resulting in high concentrations of these compounds in the sediment of contaminated areas. We evaluated the behavioral consequences of long-term chronic exposure to PAHs, by exposing zebrafish to diets spiked with three PAH fractions at environmentally relevant concentrations. Fish were exposed to these chemicals from their first meal (5 days postfertilization) until they became reproducing adults (at 6 months old). The fractions used were representative of PAHs of pyrolytic (PY) origin and of two oils...

Comparison of 0- and 2-group otolith elemental signatures to discriminate Solea solea nurseries in the bay of biscay ArchiMer
Durieux, Eric D. H.; Labonne, Maylis; Begout, Marie-laure; De Pontual, Helene.
The common sole Solea solea (L.) is a commercially important and widely distributed flatfish of the North-East Atlantic. For the Bay of Biscay stock, sole nurseries display differences in terms of quantity and quality. In fine the measure of the quality of a habitat for juveniles of a particular species is expressed by the contribution to the recruitment into the adult population. Understanding this connectivity between juvenile and adult habitats, i.e. evaluating the contribution of each nursery to a single adult stock appears essential in terms of stock management. However, this critical link is still missing for the Bay of Biscay sole stock. Determining if nurseries could be discriminated using otolith elemental composition analysis constitutes the...

Comparison of Solea solea macroparasites between two nursery-continental shelf systems in the Bay of Biscay and the Portuguese coast ArchiMer
Durieux, Eric; Marques, J.f; Sasal, P; Begout, Marie-laure; Cabral, H.
Digenean metacercariae of 0 year group common sole Solea solea (n = 70) were more abundant in the embayed nursery of the Pertuis Charentais than in the Tagus estuary nursery. Macroparasite assemblages of adult sole (n = 119) displayed only one species in common between the Bay of Biscay and the Portuguese coast continental shelves. These data highlighted the potential use of macroparasites as biological tags in various aspects of common sole ecology. (C) 2007 The Authors.

Consistency in European seabass coping styles: A life history approach ArchiMer
Ferrari, Sebastien; Millot, Sandie; Leguay, Didier; Chatain, Beatrice; Begout, Marie-laure.
Recent years have seen a growth of interest in the consistent differences in individual behaviour over time and contexts constituting so-called “individual coping styles”. An understanding of this inter-individual variation is essential to improve our knowledge of the adaptive value of behaviour. Coping styles may have implications in diverse fields, so the development of appropriate screening methods for each species appears to be the most effective way to extend our knowledge and to incorporate behavioural responses into selection-based breeding programmes, to improve the domestication and welfare of farmed fish. We tested 30 juvenile seabass (Dicentrarchus labrax) at least twice in individual-based tests (feeding recovery in isolation, aggressiveness,...

Coping styles in farmed fish: consequences for aquaculture ArchiMer
Castanheira, Maria Filipa; Conceicao, Luis E. C.; Millot, Sandie; Rey, Sonia; Begout, Marie-laure; Damsgard, Borge; Kristiansen, Tore; Hoglund, Erik; Overli, Oyvind; Martins, Catarina I. M..
Individual differences in physiological and behavioural responses to stressors are increasingly recognised as adaptive variation and thus raw material for evolution and fish farming improvements including selective breeding. Such individual variation has been evolutionarily conserved and is present in all vertebrate taxa including fish. In farmed animals, the interest in consistent trait associations, that is coping styles, has increased dramatically over the last years because many studies have demonstrated links to performance traits, health and disease susceptibility and welfare. This study will review (i) the main behavioural, neuroendocrine, cognitive and emotional differences between reactive and proactive coping styles in farmed fish; (ii) the...

De novo assembly, characterization and functional annotation of Senegalese sole (Solea senegalensis) and common sole (Solea solea) transcriptomes: integration in a database and design of a microarray ArchiMer
Benzekri, Hicham; Armesto, Paula; Cousin, Xavier; Rovira, Mireia; Crespo, Diego; Alejandro Merlo, Manuel; Mazurais, David; Bautista, Rocio; Guerrero-fernandez, Dario; Fernandez-pozo, Noe; Ponce, Marian; Infante, Carlos; Zambonino, Jose Luis; Nidelet, Sabine; Gut, Marta; Rebordinos, Laureana; Planas, Josep V.; Begout, Marie-laure; Gonzalo Claros, M.; Manchado, Manuel.
Background Senegalese sole (Solea senegalensis) and common sole (S. solea) are two economically and evolutionary important flatfish species both in fisheries and aquaculture. Although some genomic resources and tools were recently described in these species, further sequencing efforts are required to establish a complete transcriptome, and to identify new molecular markers. Moreover, the comparative analysis of transcriptomes will be useful to understand flatfish evolution. Results A comprehensive characterization of the transcriptome for each species was carried out using a large set of Illumina data (more than 1,800 millions reads for each sole species) and 454 reads (more than 5 millions reads only in S. senegalensis), providing coverages ranging from...

Digenean metacercariae parasites as natural tags of habitat use by 0-group common sole Solea solea in nearshore coastal areas: A case study in the embayed system of the Pertuis Charentais (Bay of Biscay, France) ArchiMer
Durieux, Eric; Begout, Marie-laure; Pinet, Patrick; Sasal, Pierre.
This study focused on the spatio-temporal variation in the host-parasite system, 0-group sole-digenean metacercariae, in nearshore coastal areas at relatively small spatial scale. 0-group soles were sampled using a standard beam trawl in April, May, June, August and October 2005 at nine different sites in the Pertuis Charentais area (Bay of Biscay, France). Sole density, size, Fulton's condition factor K and digenean metacercariae communities were analysed. 0-group sole concentrated in shallow and muddy areas where they accumulated digenean metacercariae. Parasite communities displayed strong spatial patterns tightly linked to the distribution of the first intermediate mollusc hosts. These parasitological data suggest that 0-group sole during their first...

Early individual electronic identification of sea bass using RFID microtags: A first example of early phenotyping of sex-related growth ArchiMer
Ferrari, Sebastien; Chatain, Beatrice; Cousin, Xavier; Leguay, Didier; Vergnet, Alain; Vidal, Marie-odile; Vandeputte, Marc; Begout, Marie-laure.
Although individual electronic tagging using PIT (Passive Integrated Transponder) tags is well established, it is mainly used for fish > 60 mm in length. Since electronic tagging is an ideal identification method, we used RFID (Radio Frequency Identification) microtags (6 mm in length, 1 mm in diameter, 10 mg in mass) to characterize individual fish from the early stages of their development and throughout their lifecycles. We used sea bass, Dicentrarchus labrax, (105 day-old fish weighing between 100 and 1100 mg) and studied the effects of intra-coelomic tagging in half the population using different endpoints including survival and tag reading, growth over 6 months and swimming responses. Dead fish were counted daily, biometric data were collected at...

Early life behavioural differences in wild caught and domesticated sea bass (Dicentrarchus labrax) ArchiMer
Benhaim, David; Pean, Samuel; Lucas, Gael; Blanc, Nancy; Chatain, Beatrice; Begout, Marie-laure.
Behavioural studies comparing hatchery and wild-caught fish are useful to improve selection for aquaculture and restocking programmes. We examined swimming behaviour characteristics in wild captured and domesticated sea bass juveniles before and after eliciting a startle response at 8 different ages and always on naive individuals. We specifically investigated whether domestication impacts juvenile sea bass behaviour and whether the first months of captivity induce behavioural modifications in wild juveniles. An apparatus was designed to mimic a predator attack by presenting a sudden visual and mechanical stimuli simultaneously in 8 arenas where single individuals were placed and video recorded. The reactivity response was evaluated and different swimming...

Ecologie comportementale des poissons : la relation poisson-environnement dans le fonctionnement des populations ArchiMer
Begout, Marie-laure.
Les facteurs environnementaux, qu’ils soient naturels, biotiques ou abiotiques, ou d’origine anthropique peuvent influencer fortement les perceptions sensorielles et les réponses adaptatives individuelles des animaux dans le milieu. L’écologie sensorielle détermine l’espace exploré par les capacités sensorielles d’un animal et tente d’établir comment les interactions sensorielles entre l’organisme et l’environnement, ou entre les organismes, modulent : leurs réponses comportementales, leurs réponses métaboliques et leur utilisation de l’espace (Dusenbery, 1992). Un tel réseau de prise d’informations se superpose au plus classique réseau trophique qui comprend les transferts et flux d’énergie, et relie les organismes à leur environnement et aux autres...

Effect of fasting on self-feeding activity in juvenile sea bass (Dicentrarchus labrax) ArchiMer
Benhaim, David; Begout, Marie-laure; Pean, Samuel; Brisset, Blandine; Leguay, Didier; Chatain, Beatrice.
In various experiments under self-feeding conditions, sea bass groups could be divided into three categories regarding feeder actuation: high, low and zero-triggering fish. In all cases few high-triggering fish were responsible for a high percentage of the feed delivery. A question was raised about the role played by feeding motivation in such high-triggering status acquisition. It was approached by applying a 3-week fasting period in order to induce similar negative specific growth rate (SGR) in two groups of fish of similar mean weight but with either a low or a high coefficient of variation for weight (CVw)(T-low: CVw similar to 11%, 3 tanks of 60 fish each; T-high: CVw similar to 20%, 3 tanks of 60 fish each). These groups were created to test the...

Effect of size grading on sea bass (Dicentrarchus labrax) juvenile self- feeding behaviour, social structure and culture performance ArchiMer
Benhaim, David; Pean, Samuel; Brisset, Blandine; Leguay, Didier; Begout, Marie-laure; Chatain, Beatrice.
This study aims to test the influence of size grading on self-feeding behaviour, social structure (measured by the percentage of triggering acts per individual), growth performances, and blood physiological variables of individually passive integrated transponder (PIT)-tagged sea bass juveniles, using a computerized on-demand feeding system coupled with a PIT tag monitoring device. Three consecutive periods of 27 days each were compared: a first period (P1) before grading (6 tanks of 100 fish; 40.2 +/- 8.9 g) followed by a second period (P2) after grading. The protocol applied aimed to create two groups of fish of similar mean weight but with either a low or a high coefficient of variation of weight (CV(w)) corresponding to an imposed difference in social...

Effects of domestication, selection and stress on the energy balance of Sea bass (Dicentrarchus labrax) in aquaculture ArchiMer
Campeas, Arnaud; Millot, Sandie; Chatain, Beatrice; Begout, Marie-laure; Alunno-bruscia, Marianne.
Reared sea bass (Dicentrarchus labrax) represent 13% of the economic weight of the Mediterranean aquaculture production (FAO, 2005) and is a subject of selection program. However, the traditional goal of selection that prevailed in the last century, i.e. increasing productivity, have to be modulated by new objectives such as better feed management or increasing fish welfare. The aim of our study is to evaluate the influence of domestication and selection, and their interactions with stress, on the energy balance in sea bass (Dicentrarchus labrax). Therefore, we used two experimental datasets and analysed their results through a mathematical model. Four strains of sea bass were studied: i) Wild strain, ii) Domesticated strain (first generation obtained by...
