Acceleration Performance of Individual European Sea Bass Dicentrarchus labrax Measured with a Sprint Performance Chamber: Comparison with High-Speed Cinematography and Correlates with Ecological Performance ArchiMer
Vandamm, Joshua P.; Marras, Stefano; Claireaux, Guy; Handelsmank, Corey A.; Nelson, Jay A..
Locomotor performance can influence the ecological and evolutionary success of a species. For fish, favorable outcomes of predator-prey encounters are often presumably due to robust acceleration ability. Although escape-response or "fast-start" studies utilizing high-speed cinematography are prevalent, little is known about the contribution of relative acceleration performance to ecological or evolutionary success in a species. This dearth of knowledge may be due to the time-consuming nature of analyzing film, which imposes a practical limit on sample sizes. Herein, we present a high-throughput potential alternative for measuring fish acceleration performance using a sprint performance chamber (SPC). The acceleration performance of a large number of...

An early-life hypoxia event has a long-term impact on protein digestion and growth in European sea bass juvenile. ArchiMer
Zambonino, Jose-luis; Mazurais, David; Dubuc, Alexia; Queau, Pierre; Vanderplancke, Gwenaelle; Servili, Arianna; Cahu, Chantal; Le Bayon, Nicolas; Huelvan, Christine; Claireaux, Guy.
Ocean warming, eutrophication and consequent decrease in oxygen lead to smaller average fish size. Although such responses are well-known in an evolutionary context, involving multiple generations, it appears to be incompatible with current rapid environmental change. Rather, phenotypic plasticity could provide a means for marine fish to cope with rapid environmental changes. However, little is known about the mechanisms underlying plastic responses to environmental conditions that favour small phenotypes. Our aim was to investigate how and why European sea bass that had experienced a short episode of moderate hypoxia during their larval stage subsequently exhibited a growth depression at the juvenile stage compared to the control group. We examined...

Assessing chronic fish health: An application to a case of an acute exposure to chemically treated crude oil ArchiMer
Mauduit, Florian; Domenici, P.; Farrell, A. P.; Lacroix, C.; Le Floch, S.; Lemaire, P.; Nicolas-kopec, A.; Whittington, M.; Zambonino-infante, Jose-luis; Claireaux, Guy.
Human alteration of marine ecosystems is substantial and growing. Yet, no adequate methodology exists that provides reliable predictions of how environmental degradation will affect these ecosystems at a relevant level of biological organization. The primary objective of this study was to develop a methodology to evaluate a fish’s capacity to face a well-established environmental challenge, an exposure to chemically dispersed oil, and characterize the long-term consequences. Therefore, we applied high-throughput, non-lethal challenge tests to assess hypoxia tolerance, temperature susceptibility and maximal swimming speed as proxies for a fish’s functional integrity. These whole animal challenge tests were implemented before (1 month) and after (1 month)...

Assessing the long-term effect of exposure to dispersant-treated oil on fish health using hypoxia tolerance and temperature susceptibility as ecologically relevant biomarkers ArchiMer
Mauduit, Florian; Farrell, Anthony P.; Domenici, Paolo; Lacroix, Camille; Le Floch, Stephane; Lemaire, Pphilippe; Nicolas-kopec, Annabelle; Whittington, Mark; Le Bayon, Nicolas; Zambonino-infante, Jose-luis; Claireaux, Guy.
Consequences of exposure to polyaromatic hydrocarbons (PAH), toxic components of crude oil, on fish has been widely documented due to their ecological and economical importance. However, although forming a valuable and consistent body of knowledge, use of these data in spill response is limited. Objective of the present study was thus to facilitate the translation of published data into information of operational value. For this, we investigated the dose‐response relationship between dispersant‐treated oil exposure and ecologically‐relevant consequences by combining laboratory and field experiments. Effects were examined over almost a year using juveniles of the slow growing, commercially important European sea bass (Dicentrarchus labrax). Moreover, a...

Associations between tissue fatty acid composition and physiological traits of performance and metabolism in the seabass (Dicentrarchus labrax) ArchiMer
Chatelier, Aurelien; Mckenzie, David; Prinet, Aurelie; Galois, Robert; Robin, Jean; Zambonino, Jose-luis; Claireaux, Guy.
Seabass were fed for 4 months with diets where the lipid was provided as either canola oil (CO), palm oil ( PO) or fish oil (FO), to generate diversity in their tissue fatty acid (FA) composition and investigate how this influenced major traits of exercise performance, cardiac performance and respiratory metabolism. In particular, based upon previous observations, we investigated the hypothesis that enriching the fish tissues with oleic and linoleic acids (OA, 18:1n-9 and LA, 18:2n-6, respectively) from the CO and PO diets would improve maximum exercise and cardiac performance, and increase aerobic metabolic scope. This proved to be the case; exercise respirometry on bass fitted with cardiac flow probes revealed that those fed CO and PO diets had a...

Avoidance threshold to oil water soluble fraction by a juvenile marine teleost fish ArchiMer
Claireaux, Guy; Queau, Pierre; Marras, Stefano; Le Floch, Stephane; Farrell, Anthony P.; Nicolas-kopec, Annabelle; Lemaire, Philippe; Domenici, Paolo.
When oil spills occur, behavior is the first line of defense for a fish to avoid being contaminated. Here, we determined the avoidance threshold of the European seabass (Dicentrarchus labrax) to the water-soluble fraction (WSF) of oil using a dual flow choice box. Our experiment revealed that a plume of 20%-diluted WSF (total PAH concentration: 8.54 μg L-1) triggered a significant avoidance response that was detected within 7.5 minutes of introducing WSF-contaminated water in the experimental set-up. However, the ecological relevance of seabass capacity to detect and avoid WSF remains to be established. In the short term, such response is indeed liable to reduce sea bass contact time with oil-contaminated water and thus preserve their functional integrity....

Biorheological properties of intertidal organic fluff on mud flats and its modification of gill ventilation in buried sole Solea solea ArchiMer
Jenkinson, Ian; Claireaux, Guy; Gentien, Patrick.
Intertidal mudflats are important nursery grounds for juveniles of many fish species. However, they are being used increasingly to farm bivalve molluscs, which produce large amounts of organic "fluff", overlying the mud. Fish such as sole, Solea solea, hide in this fluff from potential predators, but the energy consumed by respiring the fluff may be high due to its biorheological properties. We developed an ichthyoviscometer. It incorporates a freshly killed fish as a viscometer, and we developed it to measure the rheological properties of fluids and suspensions, including fluff, at scales encompassing those in gill ventilation. We have shown that the rheological behaviour of fluff is close to that of a gel with a yield stress strongly dependent on...

Calcium response of KCl-excited populations of ventricular myocytes from the European sea bass (Dicentrarchus labrax): a promising approach to integrate cell-to-cell heterogeneity in studying the cellular basis of fish cardiac performance ArchiMer
Ollivier, Helene; Marchant, James; Le Bayon, Nicolas; Servili, Arianna; Claireaux, Guy.
Climate change challenges the capacity of fishes to thrive in their habitat. However, through phenotypic diversity, they demonstrate remarkable resilience to deteriorating conditions. In fish populations, inter-individual variation in a number of fitness-determining physiological traits, including cardiac performance, is classically observed. Information about the cellular bases of inter-individual variability in cardiac performance is scarce including the possible contribution of excitation-contraction (EC) coupling. This study aimed at providing insight into EC coupling-related Ca2+ response and thermal plasticity in the European sea bass (Dicentrarchus labrax). A cell population approach was used to lay the methodological basis for identifying the...

Cardiac Molecular-Acclimation Mechanisms in Response to Swimming-Induced Exercise in Atlantic Salmon ArchiMer
Castro, Vicente; Grisdale-helland, Barbara; Helland, Stale J.; Torgersen, Jacob; Kristensen, Torstein; Claireaux, Guy; Farrell, Anthony P.; Takle, Harald.
Cardiac muscle is a principal target organ for exercise-induced acclimation mechanisms in fish and mammals, given that sustained aerobic exercise training improves cardiac output. Yet, the molecular mechanisms underlying such cardiac acclimation have been scarcely investigated in teleosts. Consequently, we studied mechanisms related to cardiac growth, contractility, vascularization, energy metabolism and myokine production in Atlantic salmon pre-smolts resulting from 10 weeks exercise-training at three different swimming intensities: 0.32 (control), 0.65 (medium intensity) and 1.31 (high intensity) body lengths s(-1). Cardiac responses were characterized using growth, immunofluorescence and qPCR analysis of a large number of target genes encoding proteins...

Cardiac preload and venous return in swimming sea bass (Dicentrarchus labrax L.) ArchiMer
Sandblom, Erik; Farrell, Anthony; Altimiras, Jordi; Axelsson, Michael; Claireaux, Guy.
Cardiac preload (central venous; pressure, Pcv), mean circulatory filling pressure (MCFP), dorsal aortic blood pressure (P-DA) and relative cardiac output (Q) were measured in sea bass (Dicentrarchus labrax) at rest and while swimming at 1 and 2 BL s(-1). MCFP, an index of venous capacitance and the upstream venous pressure driving the return of venous blood to the heart, was measured as the plateau in Pcv during ventral aortic occlusion. Compared with resting values, swimming at 1 and 2BL s(-1) increased Q (by 15 +/- 1.5 and 38 +/- 6.5%, respectively), Pcv (from 0.11 +/- 0.01 kPa to 0.12 +/- 0.01 and 0.16 +/- 0.02 kPa, respectively), MCFP (from 0.27 +/- 0.02 kPa to 0.31 +/- 0.02 and 0.40 +/- 0.04 kPa, respectively) and the calculated pressure gradient for...

Combined effects of ocean acidification and temperature on larval and juvenile growth, development and swimming performance of European sea bass (Dicentrarchus labrax) ArchiMer
Cominassi, Louise; Moyano, Marta; Claireaux, Guy; Howald, Sarah; Mark, Felix C.; Zambonino-infante, Jose-luis; Le Bayon, Nicolas; Peck, Myron A..
Ocean acidification and ocean warming (OAW) are simultaneously occurring and could pose ecological challenges to marine life, particularly early life stages of fish that, although they are internal calcifiers, may have poorly developed acid-base regulation. This study assessed the effect of projected OAW on key fitness traits (growth, development and swimming ability) in European sea bass (Dicentrarchus labrax) larvae and juveniles. Starting at 2 days post-hatch (dph), larvae were exposed to one of three levels of PCO2 (650, 1150, 1700 μatm; pH 8.0, 7.8, 7.6) at either a cold (15°C) or warm (20°C) temperature. Growth rate, development stage and critical swimming speed (Ucrit) were repeatedly measured as sea bass grew from 0.6 to ~10.0 (cold) or ~14.0...

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...

Divergence in physiological factors affecting swimming performance between anadromous and resident populations of brook charr Salvelinus fontinalis ArchiMer
Crespel, Amelie; Dupont-prinet, A.; Bernatchez, L.; Claireaux, Guy; Tremblay, R.; Audet, C..
In this study, an anadromous strain (L) and a freshwater-resident (R) strain of brook charr Salvelinus fontinalis as well as their reciprocal hybrids, were reared in a common environment and submitted to swimming tests combined with salinity challenges. The critical swimming speeds (Ucrit) of the different crosses were measured in both fresh (FW) and salt water (SW) and the variations in several physiological traits (osmotic, energetic and metabolic capacities) that are predicted to influence swimming performance were documented. Anadromous and resident fish reached the same Ucrit in both FW and SW, with Ucrit being 14% lower in SW compared with FW. The strains, however, seemed to use different underlying strategies: the anadromous strain relied on its...

Domestication compromises athleticism and respiratory plasticity in response to aerobic exercise training in Atlantic salmon (Salmo salar) ArchiMer
Zhang, Yangfan; Timmerhaus, Gerrit; Anttila, Katja; Mauduit, Florian; Jorgensen, Sven Martin; Kristensen, Torstein; Claireaux, Guy; Takle, Harald; Farrell, Anthony P..
Commercially selective breeding of Atlantic salmon (Salmo salar) primarily for rapid growth may compromise cardiorespiratory robustness and its related phenotypes. Therefore, a suite of respiratory indices was used to evaluate aerobic capacity and hypoxia tolerance to test the hypothesis that exercise training can improve the athletic robustness in both domesticated and wild strains of Atlantic salmon, but with the domesticated strain having a less cardiorespiratory plasticity and a lower athletic robustness than the wild strain. We also tested a second hypothesis that a constant acceleration screening protocol should segregate fish according to athletic robustness based on their swimming ability. These hypotheses were tested with parr from Bolaks...

Effect of exposure to petroleum hydrocarbons upon cardio-respiratory function in the common sole (Solea solea) ArchiMer
Claireaux, Guy; Davoodi, Fariba.
The long term consequences of oil exposure upon marine populations are still poorly evaluated. One particular missing piece of information relates to the link between oil exposure, individuals' ability to face environmental contingencies and populations' production and dynamics. In that context, the present paper investigates the impact of oil exposure upon fish cardio-respiratory performance, this performance being viewed as a key determinant of individual fitness. Experimental conditions replicated the contamination conditions observed during the weeks that immediately followed the Erika oil spill (west coast of France; December 1999). Sole (Solea solea), were exposed to number-2 oil for 5 days and were then challenged with an acute rise in temperature...

Effects of exposure to petroleum hydrocarbons upon the metabolism of the common sole Solea solea ArchiMer
Davoodi, Fariba; Claireaux, Guy.
On December 12th, 1999, the oil tanker Erika sank off the southern coast of Brittany (France), releasing 20 000–30 000 tons of heavy oil in the open sea. Among the affected coastal habitats were important nurseries for numerous flatfish species and particularly for the common sole, Solea solea. To investigate the potential impact of the spill on this economically significant resource, we employed Fry's concept of metabolic scope for activity to assess the deleterious effect of fuel exposure on the functional integrity of juvenile sole. Fish were captured from uncontaminated areas and experimentally exposed to contamination conditions mimicking those encountered during the weeks that followed the Erika spill. Using respirometry techniques we measured basal...

Effects of oil exposure and dispersant use upon environmental adaptation performance and fitness in the European sea bass, Dicentrarchus labrax ArchiMer
Claireaux, Guy; Theron, Michael; Prineau, Michel; Dussauze, Matthieu; Merlin, Francois Xavier; Le Floch, Stephane.
The worldwide increasing recourse to chemical dispersants to deal with oil spills in marine coastal ecosystems is a controversial issue. Yet, there exists no adequate methodology that can provide reliable predictions of how oil and dispersant-treated oil can affect relevant organism or population-level performance. The primary objective of the present study was to examine and compare the effects of exposure to untreated oil (weathered Arabian light crude oil), chemically dispersed oil (Finasol, TOTAL-Fluides) or dispersant alone, upon the ability of fish for environmental adaptation. To reach that goal, we implemented high-throughput, non-lethal challenge tests to estimate individual hypoxia and heat tolerance as surrogate measures of their capacity to...

Effects of warming rate, acclimation temperature and ontogeny on the critical thermal maximum of temperate marine fish larvae ArchiMer
Moyano, Marta; Candebat, Caroline; Ruhbaum, Yannick; Alvarez-fernandez, Santiago; Claireaux, Guy; Zambonino, Jose-luis; Peck, Myron A..
Most of the thermal tolerance studies on fish have been performed on juveniles and adults, whereas limited information is available for larvae, a stage which may have a particularly narrow range in tolerable temperatures. Moreover, previous studies on thermal limits for marine and freshwater fish larvae (53 studies reviewed here) applied a wide range of methodologies (e.g. the static or dynamic method, different exposure times), making it challenging to compare across taxa. We measured the Critical Thermal Maximum (CTmax) of Atlantic herring (Clupea harengus) and European seabass (Dicentrarchus labrax) larvae using the dynamic method (ramping assay) and assessed the effect of warming rate (0.5 to 9°C h-1) and acclimation temperature. The larvae of herring...

Effects of water viscosity upon ventilation and metabolism of a flatfish, the common sole Solea solea (L.) ArchiMer
Couturier, Christine; Rouault, Alice; Mckenzie, David; Galois, Robert; Robert, Serge; Joassard, Lucette; Claireaux, Guy.
The French Atlantic coast contains large highly productive intertidal mudflats that are colonised by juveniles of numerous flatfish species, including the common sole (Solea solea, L.). These ecosystems are also heavily exploited by the shellfish farming industry. Intensive bivalve culture is associated with substantial biodeposition (1-6 t-dw ha(-1) day(-1)), which directly or indirectly contributes to increase exopolysaccharide (EPS) concentrations at the interface between water column and seabed. EPS are long-chain molecules organised into colloids, which influence rheological properties of water, particularly viscosity. Increased water viscosity had consequences for ventilatory activity of juvenile flatfish, whereby the minimal pressure required to...

Exposure to chronic moderate hypoxia impacts physiological and developmental traits of European sea bass (Dicentrarchus labrax) larvae ArchiMer
Vanderplancke, Gwenaelle; Claireaux, Guy; Quazuguel, Patrick; Huelvan, Christine; Corporeau, Charlotte; Mazurais, David; Zambonino-infante, Jose-luis.
Since European sea bass (Dicentrarchus labrax) larvae occurred in coastal and estuarine waters at early life stages, they are likely to be exposed to reduced dissolved oxygen waters at a sensitive developmental stage. However, the effects of hypoxia at larval stage, which depend in part on fish species, remain very poorly documented in European sea bass. In the present study, the impacts of an experimental exposure to a chronic moderate hypoxia (40 % air saturation) between 30 and 38 days post-hatching on the physiological and developmental traits of European sea bass larvae were assessed. This study was based on the investigation of survival and growth rates, parameters related to energy metabolism [Citrate Synthase (CS) and Cytochrome-c Oxidase (COX)...
