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...

Locomotion and survival of two sympatric larval anurans, Bufo gargarizans (Anura: Bufonidae) and Rana zhenhaiensis (Anura: Ranidae), after partial tail loss Rev. Bras. Zool.
Ding,Guo-Hua; Lin,Zhi-Hua; Zhao,Li-Hua.
Tadpoles of two sympatric anurans, Bufo gargarizans Cantor, 1842 and Rana zhenhaiensis Ye, Fei & Matsui, 1995, were used as model organisms to examine the effects of different levels of tail loss on swimming performance and survival. On average, B. gargarizans tadpoles were shorter and had smaller tails and body mass than R. zhenhaiensis. After 75% tail loss, the survival rate of experimental and control B. gargarizans tadpoles, and of experimental tadpoles of the two species, differed significantly; the number of tadpoles surviving a complete impairment of their swimming ability did not differ between B. gargarizans and R. zhenhaiensis. After 50% tail loss, the swimming performance (swimming speed, maximum distance and number of stops) of the two...

Ocean warming combined with lower omega-3 nutritional availability impairs the cardio-respiratory function of a marine fish ArchiMer
Vagner, Marie; Pante, Eric; Viricel, Amelia; Lacoue-labarthe, Thomas; Zambonino-infante, Jose-luis; Quazuguel, Patrick; Dubillot, Emmanuel; Huet, Valerie; Le Delliou, Herve; Lefrançois, Christel; Imbert-auvray, Nathalie.
Highly unsaturated fatty acids of the omega-3 series (HUFA) are major constituents of cell membranes, yet poorly synthesised de novo by consumers. Their production, mainly supported by aquatic microalgae, has been decreasing with global change. Understanding the consequences of such reductions is essential for ectotherm consumers, since temperature tightly regulates the HUFA content in cell membranes, maintaining their functionality. Integrating individual, tissue and molecular approaches, we examined the consequences of the combined effects of temperature and HUFA depletion on the key cardio-respiratory functions of the golden grey mullet, an ectotherm grazer of high ecological importance. For four months, fish were exposed to two contrasting HUFA diets...

Passage performance of long-distance upstream migrants at a large dam on the Paraná River and the compounding effects of entry and ascent Neotropical Ichthyology
Wagner,Ricardo Luiz; Makrakis,Sergio; Castro-Santos,Theodore; Makrakis,Maristela Cavicchioli; Dias,João Henrique Pinheiro; Belmont,René Fuster.
This paper presents results of a fishway evaluation performed at the Engenheiro Sérgio Motta Hydroelectric Power Plant (known as Porto Primavera) - CESP, Paraná River, Brazil. The evaluation was designed to quantify entry and passage proportions of 4 long-distance migratory fish species: Brycon orbignyanus (piracanjuba), Piaractus mesopotamicus (pacu), Prochilodus lineatus (curimba), and Rhinelepis aspera (cascudo-preto). Proportions finding and entering the fishway differed between species, ranged from 7.4 % (Prochilodus lineatus) to 55.4% (Piaractus mesopotamicus). Also, proportion passing was different between species, ranged from 31% (R. aspera) to 100% (Prochilodus lineatus). Fish that were marked and released within the fishway had greater failure...

Sprint swimming performance of juvenile European sea bass ArchiMer
Nelson, J; Claireaux, Guy.
Despite its potential for determining animal success in a variety of ecologically important situations, very little is known about the sprint swimming performance of fishes. To evaluate whether selection on sprint swimming performance occurs in the wild, one must first demonstrate measurable and reproducible variation of sprint performance. In this study, we employ a computer-controlled laser detection system to study the sprint performance of 75 juvenile European sea bass Dicentrarchus labrax raised under uniform conditions in the laboratory. This percichthyid is a prized sport and food fish in Europe and similar ecologically to the North American striped bass Morone saxatilis. Individual European sea bass were subjected to endurance swimming performance...

The use of morphometric analysis to predict the swimming efficiency of two Neotropical long-distance migratory species in fish passage Neotropical Ichthyology
Assumpção,Lucileine de; Makrakis,Maristela Cavicchioli; Makrakis,Sergio; Wagner,Ricardo Luiz; Silva,Patrícia Sarai da; Lima,Ariane Furtado de; Kashiwaqui,Elaine Antoniassi Luiz.
This study investigated the external body morphology (based on morphometric data) and the swimming efficiency in fish passages (based on the ascent time in a fish ladder) of two Neotropical long-distance migratory species. The fish were collected in the fish ladder of the Porto Primavera Hydroelectric Power Plant (known as Engenheiro Sergio Motta), upper Paraná River, Brazil. The species differ in several morphometric ratios related to swimming performance. Prochilodus lineatus exhibited a higher muscle ratio and caudal fin length ratio. However, Leporinus elongatus showed higher values for the fineness ratio, a higher length from snout to pectoral fin base ratio, and a higher caudal peduncle depth factor. Although both species show good swimming...

Toxicity assessment of water-accommodated fractions from two different oils using a zebrafish (Danio rerio) embryo-larval bioassay with a multilevel approach ArchiMer
Perrichon, Prescilla; Le Menach, Karyn; Akcha, Farida; Cachot, Jerome; Budzinski, Helene; Bustamante, Paco.
Petroleum compounds from chronic discharges and oil spills represent an important source of environmental pollution. To better understand the deleterious effects of these compounds, the toxicity of water-accommodated fractions (WAF) from two different oils (brut Arabian Light and Erika heavy fuel oils) were used in this study. Zebrafish embryos (Danio rerio) were exposed during 96 h at three WAF concentrations (1, 10 and 100% for Arabian Light and 10, 50 and 100% for Erika) in order to cover a wide range of polycyclic aromatic hydrocarbon (PAH) concentrations, representative of the levels found after environmental oil spills. Several endpoints were recorded at different levels of biological organization, including lethal endpoints, morphological...

Use of metabolism and swimming activity to evaluate the sublethal toxicity of surfactant (LAS-C12) on Mugil platanus BABT
Barbieri,Edison.
This study aimed to investigate the toxicological effects of the LAS-C12 on Mugil platanus (mullet). Fishes exposed to 1.0 mg.L-1 for 24, 48, 72, 96 and 120 hours presented significant increase in specific routine metabolism. At the concentration of 0.5 mgL-1, the active metabolism presented a decreasing trend from 48 h of exposure on. However, only the consumption averages for 72 h were statistically different from the ones obtained for other periods of exposure. The lowest oxygen consumption in this concentration was observed for 24, 48 and 72 hours of exposure. Significant differences between the control and the concentration of 2.5 mgL-1 were observed for the different periods of exposure. It was not possible to measure the consumption of oxygen for 96...
