Vicky Lam- Post-Doc

vickypic2014_2Vicky is a Fisheries Economist and Postdoctoral Research Fellow of the Sea Around Us Project (SAUP) at the University of British Columbia (UBC). She is currently working on global catch reconstruction project.

She completed her PhD under the supervision of Dr. Rashid Sumaila in Resources Management and Environmental Studies at the Fisheries Centre, UBC in 2013. Vicky’s research interests focus on understanding the effect of climate change on the economics of major commercial marine fisheries at the global scale. Her thesis focused on understanding: (1) the global cost of fishing and its pattern under current climate regime; (2) the extent of economics impact of climate change on global fisheries in terms of change in economic variables including fishing costs, landed values and ultimately the economic rents of the fisheries sector; and (3) the socio-economic implication of the impacts of projected climate change and ocean acidification on marine resources in some regions, which are highly vulnerable to the change in climate, such as the Arctic region and West Africa. For her PhD study, she has already developed a global cost of fishing database which provides important fundamental information for scientists, researchers and fisheries managers to assess economic status of fisheries at local, regional and global scales.

Vicky has also involved in several global collaborative interdisciplinary research projects including research on the impact of ocean acidification on marine resources and the study on the indicators of the global ocean health. For a full list of her publications, please click here. [Hyperlink:]

MathieuThesis: The impact of fisheries on the trophic functioning of marine ecosystems: comparative approach and global-scale mapping

I was born in Burgundy, France and grew up in Lyon, neither of which are really sea-related places. However, many of my childhood holidays were spent near the water at my grandparents’ home in Paimpol, on the North coast of Brittany. Fishing crabs at low tide, playing on shingle beaches, and walking along the coast were great occupations for young city boy! I was stunned as an adolescent to realize the decline of crabs and abalones available, compared to harvests I recall as a child with my grandmother. I also discovered scuba diving at age 13, and started diving with my family all around the world. This set me on the track to follow the passions of my youth, and study marine ecology and fishery sciences.

After my ‘baccalaureat’ (which marked the end of high-school), I studied for entrance into the French Grandes Ecoles during two years in ‘Classes préparatoires’. I entered Agrocampus Ouest (Rennes, France) and completed an agronomy engineer diploma specializing in fishery sciences and aquaculture in 2010. During my degree, I also did an internship at the Macquarie University (Sydney, Australia) under the supervision of Dr. Culum Brown to study the behavior of the rainbowfish. We examined behavioural traits and their link with the establishment of the hierarchy in male rainbowfishes. I completed my MSc thesis working with Drs. Didier Gascuel (Agrocampus Ouest) and Luis Tito De Morais (IRD). My research assessed the potential effects of a marine protected area (MPA), the Bolong de Bamboung, in the Sine Saloum estuary (Senegal). We used ecosystem modelling approaches (Ecopath and EcoTroph) to investigate the impact of the MPA enforcement between 2003 (last fished year) and 2006-2008 (three years after the closure of the fishery).

As a PhD Candidate, I am working with Dr. Daniel Pauly at the UBC Fisheries Centre, and with Dr. Didier Gascuel at Agrocampus Ouest thanks to a joint PhD agreement. My proposed research has been developed to address concerns about the potential impacts of fisheries on underlying trophic functioning at a global scale. The aim of this study is to better understand the trophic functioning and its variability throughout ecosystems. We propose to use two well-known trophodynamic models: Ecopath with Ecosim (EwE) and EcoTroph (ET). New insights into trophic functioning could be obtained from a large meta-analysis of the hundreds of EwE models developed since the end of the 1980s. Additionally, EcoTroph is a recently developed model incorporated as a plug-in of EwE that enables the comparative analysis of Ecopath models through a uniform framework, the trophic spectrum. Using these two tools, we propose to conduct a meta-analysis of the marine ecosystems trophic functioning and the related impacts of fisheries at a global scale. We will then develop a dynamic mapping of the fishing impact on ocean biomass and its trophic distribution.

Lydia Teh – Post-Doc

Lydia completed her PhD at UBC’s Resource Management and Environmental Studies programme in 2011. Her thesis focused on fishers’ behaviour and spatial management of small-scale fisheries. Lydia joined the Sea Around Us in 2012 and has worked on marine fish catch reconstructions in Southeast Asia. Since 2014, she has been the Sea Around Us post-doc for the Ocean Health Index as part of our partnership with Conservation International.

Krista Greer – Research Assistant

Krista is a from a small town in Ontario, Canada. While her initial undergraduate focus was Biological Anthropology, she found that her long-time interests in marine conservation could not be suppressed. As such, she went on to study Marine Biology and Zoology at James Cook University in Australia. Throughout her undergraduate years, Krista had the opportunity to participate in field work all over the world including Costa Rica, Kenya, Seychelles and Borneo. In September 2011, she arrived at the University of British Columbia to do her Masters under the supervision of Dr. Daniel Pauly. Her thesis focused on the carbon emissions of the world’s fishing fleets since 1950 and what the “true” cost of fishing is when its environmental impacts are adequately considered. She now works as a research assistant on fishing effort and CO2 databases.

Outside of her research, Krista loves to read and participate in outdoor activities. In particular she enjoys scuba diving, camping, beach walking and spending time with her dog, Nelly.
