Doctoral student at Department of animal nutrition and management. Working on Project “Alternative feed to fish: Bioactive components effect on gut microbiota, metabolism and immunity”.

Presentation

My main interest is to gain better understanding of how feeding of dietary supplements, derived from new and sustainable sources, affect the gut micro flora, metabolism and gene expression of rainbow trout in a way to develop sustainble feeds for aquaulture industry.

Research

Finding cheap and sustainably available feedstuffs, alternative to fishmeal and soy protein, are one of the highest priorities in aquaculture research. In this context, waste and by-products from households, agriculture and forestry as potential sources of feed materials for feed production are now under investigation. Edible filamentous fungi (Neurospora intermedia), birch trees processed cellulose (Cellobiose) and organic waste cultivated (Yarrowia lipolytica) are some of potential feed sources. These feed materials contain bioactive substances, such as chitin, manans, beta-glucans, cellooligosaccharides. In the framework of this research, we will focus on understanding the interaction between diet, gut microflora and host in rainbow trout. Additionally, looking into intestinal health and metabolism.
