Effect of temperature on growth and energy metabolism of Atlantic Charr

The aim of the project is to evaluate growth efficiency, food requirements and energy metabolism of Arctic charr (Salvelinus alpinus) at different temperatures. Moreover, in this project we will study the ability of the Arctic charr to meet variations in energy requirements at different temperatures. Growth rate and food requirements depend mainly on the rearing temperature but both these factors are critical for the financial outcome of aquacultural farms. The Arctic charr is a Nordic species which has adapted to survive at low temperatures, indeed it can live at temperature ranging from 1°C up to 18°C, with an optimal growth temperature at 15-16°C. Since the rearing temperature is an important part of the operation cost of aquacultural farms the results of this project will be an important input for the calculation of the feasibility of setting up an Arctic charr farm.
