PhD project title:
Biological effects of crude oil in fish species from the Barents Sea.
PhD project description:
The main objective of my PhD project is to elucidate the biological effects of petroleum exposure in fish on survival and fitness of early life stages (ELS). On the one hand, we will determine the toxicity of different crude oil related contaminants in fish early life stages directly exposed to the toxicant. With this study, we challenge a common belief that PAHs are mainly responsible for the toxicity of the water-soluble fraction of crude oil and act via specific pathways. On the other hand, we will investigate indirect effects of crude oil exposure on gametes and ELS. We will analyse contaminant accumulation in oocytes arising from parental transfer and study the endocrine disruption potential of crude oil in adult fish via molecular changes in the brain-pituitary-gonad-liver axis.
