My main research goal is to obtain better understanding of nutritional physiology of fish, particularly in their early ontogeny. More specifically, I am interested in how different forms of dietary amino acids affect fish larvae, development, health, intestinal transport, and hormonal regulation. In my work I am looking at different dietary dipeptide configurations, health-promoting peptides, and protein hydrolysate profiles that help to improve dietary protein utilization in young fish. In addition, my research focuses on ways of reducing the use of live feeds in hatcheries and improvement of current larval rearing techniques to improve fish production.  Simultaneously, my work also investigates how different protein sources alternative to fishmeal affect digestive processes and metabolism in fish.
