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.

The result was expressed in normalized units n.
