Unfamiliar congener used as a visual attractor in wild caught and domesticated sea bass (Dicentrarchus labrax) placed in a T-maze
Provedor de dados: 5
Autores: Benhaim, David; Begout, Marie-laure; Chatain, Beatrice.
The present work compared wild-caught and domesticated sea bass juveniles swimming activity, exploration and visual attraction induced by an unfamiliar congener located behind a transparent wall at the end of one arm of a T-maze. This cognitive challenge was based on the hypothesis that placed into a novel and therefore stressful environment; the fish would adopt a gregarious behaviour even though they were not familiar with the present congener. Twenty individuals of similar size from both origins were individually tested. After a 5min acclimatization period, the wall of the start-box was removed and the maze was filmed during 20 min. Different swimming variables including angular velocity (Vang), total distance travelled (Dtot), velocity mean (Vel), time...

Long-term dietary-exposure to non-coplanar PCBs induces behavioral disruptions in adult zebrafish and their offspring
Provedor de dados: 5
Autores: Pean, Samuel; Daouk, Tarek; Vignet, Caroline; Lyphout, Laura; Leguay, Didier; Loizeau, Veronique; Begout, Marie-laure; Cousin, Xavier.
The use of polychlorinated biphenyls (PCBs) has been banned for several decades. PCBs have a long biological half-life and high liposolubility which leads to their bioaccumulation and biomagnification through food chains over a wide range of trophic levels. Exposure can lead to changes in animal physiology and behavior and has been demonstrated in both experimental and field analyses. There are also potential risks to high trophic level predators, including humans. A maternal transfer has been demonstrated in fish as PCBs bind to lipids in eggs. In this study, behavioral traits (exploration and free swimming, with or without challenges) of contaminated zebrafish (Danio rerio) adults and their offspring (both as five-day-old larvae and as two-month-old fish...

Measuring cultured fish swimming behaviour: first results on rainbow trout using acoustic telemetry in tanks
Provedor de dados: 5
Autores: Begout, Marie-laure; Lagardere, Jean-paul.
An experiment was conducted to measure swimming activity of rainbow trout (254.0 +/- 33.7 g) held in outdoor tanks under three culture conditions with stocking density used to generate differences: 27 (Culture Density 1, CD1), 80 (CD2) and 136 kg m(-3) (CD3). Fish were fed dry pellets at 1% of tank biomass from 9h00 to 13h00 with automatic feeders. Using acoustic telemetry, fish positions were monitored every 5 s during 48 h for nine fish (three in each treatment). Swimming behaviour was analysed in terms of trajectories: they varied between (i) holding position (high turning angles), (ii) chaotic trajectories (equal use of all turning angles) and (iii) circular swimming (average turning angle of 60degrees). Space utilisation differed for each culture...

Linking swimming performance, cardiac pumping ability and cardiac anatomy in rainbow trout
Provedor de dados: 5
Autores: Claireaux, Guy; Mckenzie, David; Genge, A; Chatelier, Aurelien; Aubin, Joel; Farrell, Anthony.
We exploited the inherent individual diversity in swimming performance of rainbow trout Oncorhynchus mykiss to investigate the hypothesis that maximum cardiac performance is linked to active metabolic rate (AMR) and critical swimming speed (U-crit). Six hundred juveniles (body mass similar to 150 g) were screened using a swimming challenge of 1.2 m s(-1) to identify 'poor swimmers' and 'good swimmers', i.e. the first and last 60 fish to fatigue, respectively. These 120 fish were individually tagged and then reared in common tanks for 9 months, where they grew at similar rates and achieved a similar body mass of approximately 1100 g. Critical swimming speed (U-crit) was then measured individually in tunnel respirometers, with simultaneous recordings of...

Early life behavioural differences in wild caught and domesticated sea bass (Dicentrarchus labrax)
Provedor de dados: 5
Autores: 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...

Sedentary behaviour establishment in 0-group common sole Solea solea: a laboratory video-tracking study
Provedor de dados: 5
Autores: Durieux, Eric; Le Duigou, Mathieu; Millot, Sandie; Sasal, Pierre; Begout, Marie-laure.
Spontaneous swimming activity of 0-group common sole (Solea solea) was evaluated using a video-tracking system under laboratory conditions. An experiment was conducted during two consecutive days on individuals sampled in June, July, September and November (2004) in a coastal nursery ground (Pertuis Charentais, Bay of Biscay, France). The measured behavioural variables were: distance travelled and frequency of occurrence of burying, swimming and immobility. 0-group sole showed a relatively clear circadian activity in line with the artificial light conditions (day, twilight and night). Swimming activity of 0-group sole decreased drastically from June to July, thereafter remaining at a very low level in September and November. Such important changes reflect...

Exploration behaviour and flight response toward a stimulus in three sea bass strains (Dicentrarchus labrax L.)
Provedor de dados: 5
Autores: Millot, Sandie; Begout, Marie-laure; Chatain, Beatrice.
Domestication and selection may affect fish behaviour, sometime as soon as at the first generation of domestication. However, knowledge about how both processes impact on fish spatial exploration and swimming activity still is to be improved. The objective of this experiment was (i) to evaluate spatial exploration behaviour and swimming activities of three sea bass strains having different domestication and selection levels and (ii) to analyse their responses to an acute stress. Sea bass exploration and swimming activities were studied before, during and 40 min after a stimulation (standardized fall of an object). The experimental tank was divided in to four zones, and the time spent, the distance travelled in each zone and the swimming complexity were...

Caractérisation de l’adaptation comportementale des téléostéens en élevage : plasticité et effets de la domestication
Provedor de dados: 5
Autores: Benhaim, David.
The farming of aquatic animals has started recently in comparison with that of terrestrial species which domestication started 10 500 years ago. Aquaculture is however the fastest growing animal food-production sector. This sector has now to face several challenges threatening its sustainability. Indeed, aquaculture future largely depends upon the reduction of the reliance on feeds based ingredients derived from wild fishery resources, upon a better knowledge of fish domestication process and of the adaptation mechanisms and related welfare potential. The present work aims at a better understanding of the adaptation to farming conditions through a behavioural approach based on the comparison between wild vs. domesticated populations of three species: a...

Genetic differences for behaviour in juveniles from two strains of brown trout suggest an effect of domestication history
Provedor de dados: 5
Autores: Benhaim, David; Guyomard, Rene; Chatain, Beatrice; Quillet, Edwige; Begout, Marie-laure.
Because captivity constitutes a drastic environmental change, domestication is expected to induce a rapid genetic selection for behavioural traits. In this study, we searched for genetic differences in behaviour among brown trout juveniles from two strains differing for their domestication history, i.e. an almost pure native wild Mediterranean population (W) and an Atlantic domesticated strain (D). In order to assess pure genetic differences among strains, males from the two origins were mated with Mediterranean females to produce two experimental crosses (WW and WD). The swimming activity characteristics of individual WW and WD juveniles were compared before and after the application of a stress (light switched off suddenly, followed by a 5-min period of...

The shy prefer familiar congeners
Provedor de dados: 5
Autores: Benhaim, David; Ferrari, Sebastien; Chatain, Beatrice; Begout, Marie-laure.
The shy–bold continuum is both a fundamental aspect of human behavior and a relatively stable behavioral trait for many other species. Here we assessed whether shy individuals prefer familiar congeners, taking the European sea bass, a recently domesticated fish showing similar behavioral responses to wild fish, as a model to better understand the inter-individual variability in social behavior previously observed in this species. In the wild, the link between familiarity i.e. the preference of fish for familiar congeners and boldness could be part of the mechanism underlying shoaling formation in fish. Thirty fish were individually tested in a device designed to assess the preference for a familiar vs. an unfamiliar congener on the basis of visual cues...

Changes in Brain Monoamines Underlie Behavioural Disruptions after Zebrafish Diet Exposure to Polycyclic Aromatic Hydrocarbons Environmental Mixtures
Provedor de dados: 5
Autores: 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...
