View the full release here: By exposing fish to a 4—19 °C temperature gradient in an annular preference chamber we recorded the preferred temperature of wild juvenile G. Influence of the coronary circulation on thermal tolerance and cardiac performance during warming in rainbow trout. Communication in Broiler Chickens Gallus gallus domesticus. Here we show that rainbow trout Oncorhynchus mykiss treated with cortisol in the food for 45 days have enlarged hearts with lower maximum stroke volume and cardiac output. In this project, we investigate the effects of environmental warming on coronary blood flow, and how a blockade of coronary blood flow affect cardiac function and whole animal thermal tolerance in rainbow trout. Despite the potential benefits of increased mixing and transport of imbibed water for increasing the efficiency of absorptive processes, the effect of water salinity on intestinal motility in teleosts remains unexplored.
Data is reported as mean ± SD or median and range.

When the dose was increased to 0. These contradictory results are discussed with regard to animal welfare and stress physiological responses. The age match was made pairwise ±3 years. The result was expressed in normalized units n. By manipulating oxygen availability via environmental hyperoxia and blood oxygen carrying capacity via experimentally-induced anemia in European perch Perca fluviatilis, Linneauswe investigated the effects of oxygen transport capacity on aerobic scope and the critical thermal maximum CTmax.
