The specific dynamic action (SDA) of fishes represents the increase in metabolism following feeding. Although all macronutrients are considered contributing factors, protein is considered to play the greatest role in increasing metabolism post feeding. Exactly how much is however not known.
The purpose of this project is to establish a correlation between dietary protein intake and magnitude of the SDA response in rainbow trout, using specifically formulated diets (varying in protein, fat and carbohydrate content) from BioMar. It is furthermore an aim in the project to determine how protein content in the diet influences protein (measured as nitrogen) retention in fishes.
The data obtained in the current project is important for understanding contributing factors if macronutrients in the SDA response in this species, but also for the ability to predict oxygen requirements of fishes in aquaculture post feeding.
The project is available for a student in the fall of 2017, alternatively spring 2018. Students are expected to spend around 4 months at DTU Aqua in Hirtshals. Cheap accomodation available. Some financial support possible. Contact supervisor for informal discussion of possibilities.
