Current projects:

Climate change, eutrophication and environmental toxins – interacting effects on molecular physiology of fish

The purpose of the project is to investigate the physiological responses of the fish to different environmental problems and especially their interactions. The focus will be on climate change, eutrophication (hypoxia/anoxia) and oil disasters. In the project we will study how the physiological tolerance levels of fish change in different kind of exposures and do the environmental problems have synergistic or antagonistic effects on the capacity of fish to tolerate the stressors. Moreover, at cellular level we will investigate which factors are connected to the possible changes in the tolerance levels. Furthermore, the epigenetic influence will be also taken into consideration.

FitSmolt– aiming for robust smolts

The purpose of this project is to investigate the ways to increase the survival rate of farmed Atlantic salmon smolts when they are transferred to sea to grow. The project will hold three different parts: 1) the physiological comparison of wild and farmed smolts, 2) could the selection for higher swimming capacity increase other physiological capacities at the same time – and increase the survival rate and 3) influence of training on different physiological capacities and thereafter on survival. The project leader is Harald Takle from Nofima, Norway.

Molecular basis of thermotolerance

It has been shown that cardiac function is the limiting factor of the thermotolerance in several fish species. In this project we will investigate at cardiac molecular level that which molecular factors limit the function of the heart at high temperatures. The focus will be on different excitation contraction coupling proteins and we will also study the energy metabolism of the heart. These investigations will be done with different populations of sockeye salmon in Vancouver, Canada.
