Background Zebrafish has been largely accepted as a vertebrate multidisciplinary model but its usefulness for exercise physiology hampered by the scarce knowledge on swimming economy, optimal speeds and cost of transport. Therefore, we have performed individual group-wise experiments to quantify economy demonstrate effects growth in adult zebrafish. Methodology/Principal Findings Individual zebrafish (n = 10) were able swim at critical speed (Ucrit) 0.548±0.007 m s−1 or 18.0 standard body...
We have sequenced the genome of endangered European eel using MinION by Oxford Nanopore, and assembled these data a novel algorithm specifically designed for large eukaryotic genomes. For this 860 Mbp genome, entire computational process takes two days on single CPU. The resulting assembly significantly improves previous draft based short reads only, both in terms contiguity (N50 1.2 Mbp) structural quality. This combination affordable nanopore sequencing light weight promises to make...
AMPK, a master metabolic switch, mediates the observed increase of glucose uptake in locomotory muscle mammals during exercise. AMPK is activated by changes intracellular AMP∶ATP ratio when ATP consumption stimulated contractile activity but also AICAR and metformin, compounds that transport mammalian cells. However, possible role regulation metabolism skeletal has not been investigated other vertebrates, including fish. In this study, we effects activators on uptake, activity, cell surface...
The European eel migrates 5,000-6,000 km to the Sargasso Sea reproduce. Because they venture into ocean in a pre-pubertal state and reproduce after swimming for months, strong interaction between sexual maturation is expected. Many trials have been performed 22 swim tunnels elucidate their performance impact on maturation. eels are able long distances at cost of 10-12 mg fat/km which 4-6 times more efficient than salmonids. total energy costs reproduction correspond 67% fat stores. During...
Swimming exercise at optimal speed may optimize growth performance of yellowtail kingfish in a recirculating aquaculture system. Therefore, swimming speeds (U opt m s(-1) or body lengths s(-1), BL s(-1)) were assessed and then applied to determine the effects long-term forced sustained U on juvenile kingfish. was quantified Blazka-type swim-tunnels for 145, 206, 311 mm juveniles resulting values of: (1) 0.70 4.83 (2) 0.82 3.25 (3) 0.85 2.73 s(-1). Combined with literature data from larger...
Deep RNA sequencing (RNA-seq) was performed to provide an in-depth view of the transcriptome red and white skeletal muscle exercised non-exercised rainbow trout (Oncorhynchus mykiss) with specific objective identify expressed genes quantify transcriptomic effects swimming-induced exercise. Pubertal autumn-spawning seawater-raised female were rested (n = 10) or swum for 1176 km at 0.75 body-lengths per second in a 6,000-L swim-flume under reproductive conditions 40 days. Red fish (4 lanes)...
The adult skeletal muscle is a plastic tissue with remarkable ability to adapt different levels of activity by altering its excitability, contractile and metabolic phenotype mass. We previously reported on the potential zebrafish as tractable experimental model for exercise physiology, established optimal swimming speed showed that swimming-induced potentiated somatic growth. Given underlying exercise-induced transcriptional mechanisms regulating mass in vertebrates are not fully understood,...
Abstract We review knowledge on applications of sustained aerobic swimming as a tool to promote productivity and welfare farmed fish species. There has been extensive interest in whether providing active species with current swim against can growth. The results are not conclusive but the studies have varied species, life stage, speed applied, feeding regime, stocking density other factors. Therefore, much remains be understood about mechanisms underlying findings ‘swimming‐enhanced growth’,...
Commonly, female European eels are injected weekly with pituitary extract (PE) from carp (CPE) or salmon (SPE) to induce sexual maturation. However, a PE is mixture of gonadotropins and other hormones that not specific for eel rapidly cleared circulation. The aim this study was therefore test the effects highly stable eel-specific recombinant (rGTHs) on oocyte development in vitro vivo eels. For trial, dose–effect responses maturing oocytes CPE luteinizing hormone (rLH) were studied before...
This study investigated the heart rate (HR) and acceleration (AC) dynamics of Atlantic salmon ( Salmo salar ) during a swim fitness test in tunnel. Experimental fish were implanted with data loggers equipped HR AC sensors. These fish, controls that not implanted, subjected to swim-fitness at incremental speeds from 0.2 1.0 m.s –1 . Oxygen consumption (MO 2 locomotory behavior monitored. Subsequently, these stress challenge further link between induced AC. When swimming , (N = 19) was high...
The aim of this study was to investigate swimming performance and oxygen consumption as non-lethal indicator traits production parameters in Atlantic salmon Salmo salar L. Gilthead seabream Sparus aurata A total 34 individual fish each species were subjected a series experiments: (1) critical speed (Ucrit) test swim-gutter, followed by (2) two starvation-refeeding periods 42 days, (3) experiments coupled respirometry swim-tunnels. Ucrit assessed first it predictor trait. Starvation-refeeding...
A longer on-land rearing period of Gilthead seabream Sparus aurata before transfer to sea-cages would allow the farmer benefit from exercise-enhanced growth, resilience, and robustness as induced by increasing water flow in tanks. In this study, physiological effects flow-conditioning were investigated subjecting large groups experimental fish minimal or regimes inducing swimming exercise at 1 2 body length (BL) s −1 for a 8 months (February–October) 1,500 L Fish representing three treatment...
It is well-established that sustained exercise training can enhance brain plasticity and boost cognitive performance in mammals, but this phenomenon has not received much attention fish. The aim of study was to determine whether swimming juvenile Atlantic salmon. Brain assessed by both mapping the whole telencephalon transcriptome conducting telencephalic region-specific microdissections on target genes. We found 1772 transcripts were differentially expressed between control groups. Gene...
Abstract This paper aims at assessing the reproductive segregation within endemic Barbus (renamed Labeobarbus) species flock of Lake Tana (Ethiopia). Migration, followed by temporal and spatial in upstream tributaries two inflowing rivers was studied systematically over 1999 2000 spawning seasons. Physical events that may trigger lacustrine migration characterise suitability grounds were analysed. Six migrate 30-40 km Gumara River during declining flow, just after rainy season. Spawning...
