Effect of food shortage and temperature on age 0+ salmonids: a contribution to predict the effects of climate change.

Brown trout Salmo trutta alevins were maintained at 8 and 11° C at three conditions over a 9 day period from yolk sac exhaustion: fed ad libitum, starved or fed ad libitum after starvation. Whole-body gene expressions for proteins involved in energy metabolism and the two primary proteolytic pathways were assessed. This study is the first to show an over-expression of proteasome and autophagy-related genes in young stages of salmonids, particularly at 11° C.
