Engineering a population balance model for long-term fish stock prediction
Engineering a population balance model for long-term fish stock prediction My PhD project aims to develop and implement an age-structured, spatially explicit model to predict the long-term development of fish stocks. The model tries to combine the merits both of individual based models and classical population dynamics models, which treat entire fish stocks as their… DetailsAcoustic tracking of juvenile blue sharks (Prionace glauca) in Nova Scotia waters from receivers positioned near N.S. offshore oil and gas platforms
Acoustic tracking of juvenile blue sharks (Prionace glauca) in Nova Scotia waters from receivers positioned near N.S. offshore oil and gas platforms In 2013, the Deep Panuke E&T and R&D Fund supported Dalhousie University’s Ocean Tracking Network proposal to conduct acoustic telemetry work in the Deep Panuke offshore oil and gas development region of Canada’s… DetailsOverfishing in a nutshell
Despite being the world’s largest rays and providing significant revenue through dive tourism, little is known about the population status, exploitation and trade volume of the Mobulidae (mobulids; Manta and Mobula spp.). There is anecdotal evidence, however, that mobulid populations are declining.
DetailsOperationalizing big data for ocean conservation
MPAs have long been recognised as a tool to protect marine biodiversity. Through temporal and/or spatial closures and management of designated areas, the maintenance and recovery of special ecosystems, processes, habitats and species and their sustainable use and conservation are promoted. Damaging practises such as destructive fishing methods and other harmful human activities are excluded in order to create protected zones for species’ reproduction and growth. Today most MPAs can be found in coastal waters worldwide whereas large MPAs in offshore waters beyond the national jurisdiction are still rare.
For my PhD project I focus on how large Marine Protected Areas (MPAs) influence ecosystem services and fisheries activities. I am looking at effects of the establishment of MPAs on fishing fleet behaviour such as a possible relocation of fishing efforts to other areas or to the borders of MPAs to benefit from spillover effects. It is important to understand the fishermen’s reactions to protected areas in order to develop a functional network of High Seas MPAs protecting marine resources from overexploitation.
I am participating in the German-Canadian Transatlantic Ocean System Science and Technology (TOSST) graduate programme which addresses key issues facing the North Atlantic under three distinct themes: Seafloor Structures, 4D water mass dynamics and Ecosystem Hotspots. The graduate programme is hosted by Dalhousie University in Halifax, Canada and the GEOMAR as well as Christian-Albrechts University in Kiel, Germany.
