Optimization of feed ingredients has mainly focused on growth and pre-utilization, while the metabolic effect of replacing fishmeal with vegetable protein sources has been little studied. Generally, the needs of amino acids for salmon and other fish are determined by what is required to maximize growth and protein deposition in the animal. Recent experiments have shown that today's sustainable feed, which can contain a relatively high content of protein from plants, can result in poorer growth and or change the deposition of fat and protein. It has also been shown that the choice of protein sources can affect the metabolism of fish. It may seem that fish may have a changed need for given amino acids when the traditional fishmeal is replaced with alternative protein ingredients.
The project's goal is to integrate and develop new basic knowledge in the protein / amino acid industry to be better equipped to tailor new feeds that provide better fish health, quality and growth based on renewable protein resources. The project's professional challenge will increase the understanding of the need for and balance between amino acids in different tissues. This becomes important when using alternative protein sources that contain a different amino acid composition than fishmeal.
Study interactions in metabolism with emphasis on methylation reactions and the ratio of amino acids (i.e. methionine, arginine and lysine). Both in vivo and in vitro studies will be used to look at the type of growth and metabolism in different tissues / cells Interactions in the metabolism between different tissues. Furthermore, absorption of amino acids into cells will be investigated.
