Are coping styles consistent in the teleost fish Sparus aurata through sexual maturation and sex reversal? ArchiMer
Castanheira, Maria Filipa; Paramo, Sonia Martinez; Figueiredo, F.; Cerqueira, Marco; Millot, Sandie; Oliveira, Catarina C. V.; Martins, Catarina I. M.; Conceicao, Luis E. C..
Individual differences in behaviour and physiological responses to stress are associated with evolutionary adaptive variation and thus raw material for evolution. In farmed animals, the interest in consistent trait associations, i.e. coping styles, has increased dramatically over the last years. However, one of limitations of the available knowledge, regarding the temporal consistency, is that it refers always to short-term consistency (usually few weeks). The present study used an escape response during a net restraining test, previously shown to be an indicative of coping styles in seabream, to investigate long-term consistency of coping styles both over time and during different life history stages. Results showed both short-term (14 days) consistency...

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...

Bizygomatic Width and its Association with Social and Personality Traits in Males International Journal of Morphology
Gabarre-Mir,Julián; Navarro-Pastor,José B; Gabarre-Armengol,Cristina; Estaún-Ferrer,Santiago.
This study will examine how differences in measurements between bizygomatic and bigonial arches of the human face can provide relevant information regarding personality and abilities of the subject. Sample: 82 males. Group A: 55 subjects with the bizygomatic arch in contraction. Group B: 27 subjects without the bizygomatic arch in contraction. Subjects performed self-assessment tests in the following areas: ability incorporating themselves into the group, alexithymia and emotional expressiveness. Group A showed greater self-sufficiency and independence than group B, greater difficulty in describing and verbally expressing their emotions, less ability to express themselves emotionally through other forms of communication and reduced willingness to cooperate...

Caractérisation de l’adaptation comportementale des téléostéens en élevage : plasticité et effets de la domestication ArchiMer
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...

Context dependency of trait repeatability and its relevance for management and conservation of fish populations ArchiMer
Killen, S. S.; Adriaenssens, B.; Marras, S.; Claireaux, Guy; Cooke, S. J..
Repeatability of behavioural and physiological traits is increasingly a focus for animal researchers, for which fish have become important models. Almost all of this work has been done in the context of evolutionary ecology, with few explicit attempts to apply repeatability and context dependency of trait variation toward understanding conservation-related issues. Here, we review work examining the degree to which repeatability of traits (such as boldness, swimming performance, metabolic rate and stress responsiveness) is context dependent. We review methods for quantifying repeatability (distinguishing between within-context and across-context repeatability) and confounding factors that may be especially problematic when attempting to measure...

Coping styles in European sea bass: The link between boldness, stress response and neurogenesis ArchiMer
Alfonso, Sebastien; Sadoul, Bastien; Gesto, Manuel; Joassard, Lucette; Chatain, Beatrice; Geffroy, Benjamin; Bégout, Marie-laure.
Coping styles consist of a coherent set of individual physiological and behavioral differences in stress responses that are consistent across time and context. Such consistent inter-individual differences in behavior have already been shown in European sea bass (Dicentrarchus labrax), but the associated mechanisms are still poorly understood. Here, we combine physiological measurements with individual behavioral responses in order to characterize coping styles in fish. Fish were tagged and placed in a tank for group risk-taking tests (GRT) at 8 months of age to evaluate boldness using the proxy latency of leaving a sheltered area towards an open area. A subsample of these fish were individually challenged 16 months later using an open field test (OFT), in...

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...

Domestication, sélection et comportement du bar: variabilité des aptitudes comportementales et de la tolérance au stress de groupes génétiquement distincts de bar, Dicentrarchus labrax ArchiMer
Millot, Sandie.
The culture of aquatic species has grown much more rapidly in recent years than that of terrestrial species. Consequently, aquatic livestock welfare is a growing concern for society. However, unlike the many studies of terrestrial animal welfare, few scientific data exist concerning fish welfare. It is generally recognized that the aquaculture environment exposes fish to many repeated stress factors which affect their health, growth, reproductive performance and feeding behaviour. Even if stress responses do not highlight all welfare disturbances, it is generally admitted that they reveal a poor welfare. Among the solutions investigated to reduce fish stress, domestication and selection appear to be the favoured approaches. However, selection has generally...

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...

Exploration behaviour and flight response toward a stimulus in three sea bass strains (Dicentrarchus labrax L.) ArchiMer
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...

Self-feeding behaviour and personality traits in tilapia: a comparative study between Oreochromis niloticus and Sarotherodon melanotheron ArchiMer
Benhaim, David; Akian, Dieudonne; Ramos, Mathieu; Ferrari, Sebastien; Yao, Kouakou; Begout, Marie-laure.
Hybridization aims at combining valuable traits from two species into a single group. Nile tilapia Oreochromis niloticus (NT) and Black-chinned tilapia Sarotherodon melanotheron (BCT) are respectively characterized by fast growth and water salinity tolerance which attract the breeders who could take advantage of both species. The first step is to characterize both species behavior in different contexts. The aim of this study was to compare the self-feeding behaviour between NT and BCT with a design allowing to reveal individual and group feed demand behaviour and then to identify the individual specialization that builds around the device and the food dispenser. The second objective was to estimate the links between the individual specialization and...

The shy prefer familiar congeners ArchiMer
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...

Unfamiliar congener used as a visual attractor in wild caught and domesticated sea bass (Dicentrarchus labrax) placed in a T-maze ArchiMer
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...
