Biografie

I hold a Bsc degree In Watermangement from the HZ University of applied sciences, Vlissingen (The Netherlands) and a Msc in Aquaculture and Marine Research Management from the Wageningen University. Through my years of studying, I became fascinated by the research field in aquaculture and all the challenges related to this sector. For this reason during my last year of my master I did two research theses. In my first thesis I studied the phosphorus requirements in rainbow trout (Oncorhynchus mykiss). For my second thesis (minor), I got the chance to go abroad for an European project (AquaExcell) and do my thesis at INRA, France. Here I investigated the effect of dissolved oxygen concentration on the diet preference of rainbow trout (Oncorhynchus mykiss).

Before his current position as PhD-candidate, I worked as fish husbandry technician on a salmon hatchery (Hjatland Seafarms Limited Grieg Seafood) at the Shetland Islands, Schotland. The facility comprises of four state-of-the-art recirculation units, with a total tank volume of over 7500 m3. Here I developed a lot of practical skills and got insights of the producting sector of aquaculture. In October 2015 I started as a PhD-student at Wageningen UR. The NWO funded project I am involved in is entitled Green aquafeeds: unlocking non-starch polysaccharides to improve feed utilization and probiotic benefits. In this project he anticipates on the trend in aquaculture of partially replacing fish meal by plant protein in aquaculture feeds, thereby increasing the level of non-starch polysaccharides (NSP, fibres) in the diet. The project will assess the interplay between dietary NSPs and exogenous enzymes by looking into NSP breakdown, fermentation products, and into microbiota composition and shifts. Knowledge generated through the project will allow to develop the concept of using more plants based diets (high in NSP), while improving nutrient use efficiencies and minimizing pollution through the supplementation of enzymes.
