Rob van Gemert
MARmaED Early Stage Researcher from The Netherlands started working at the National Institute of Aquatic Resources, Technical University of Denmark in November
Rob van Gemert made his PhD at DTU Aqua
I am one of the two PhD students working on the MARmaED project at DTU Aqua in Denmark. I’m not Danish though; I was actually born in the Netherlands, in a small polder village called Zeewolde. I followed a BSc Biology at Wageningen University, where I specialized in Ecology & Biodiversity. During my Bachelor I took a minor in Marine Living Resources, which sparked my interest in continuing to pursue this field in academics. I therefore continued with an MSc Biology and the specialty Marine Biology, also at Wageningen University. My stay at DTU Aqua started with my MSc Thesis, which I wrote at DTU Aqua’s Centre for Ocean Life and which focused on modelling the effects of different fisheries selectivities on maximum sustainable yield, and the role of density-dependent regulation therein. For MARmaED I plan to continue focusing on density dependence. In current stock assessment models, only the stock-recruitment relationship incorporates some form of density-dependent regulation. After the larval stage, it is assumed that no more density-dependent processes take place. However, a significant body of literature suggests that density-dependent processes are present at all life stages of marine fish stock. Incorporating these processes into stock assessment models may therefore lead to improved fisheries reference points and contribute to the optimal sustainable exploitation of marine fish stocks. I will therefore investigate how density-dependent processes can influence the setting of optimal fisheries reference points. For this I will be using size-based models together with empirical evidence. I will be supervised by prof. Ken Haste Andersen.
