From tiny phytoplankton to massive tuna: how climate change will affect energy flows in ocean ecosystems

Phytoplankton are the foundation of ocean life, providing the energy that supports nearly all marine species. Levels of phytoplankton in an ocean area may seem like a good predictor for the amount of fish that can be caught there, but a new study by Nereus Program researchers finds that this relationship is not so straightforward

Scenarios for investigating the future of Canada’s oceans and marine fisheries under environmental and socioeconomic change

Fisheries Economics Research Unit (UBC) Research Associate Louise Teh, Nereus Director of Science William Cheung, and OceanCanada Director and Nereus Research Associate (Honourary) Rashid Sumaila recently had a paper (“Scenarios for investigating the future of Canada’s oceans and marine fisheries under environmental and socioeconomic change“) published in Regional Environmental Change, wherein they review existing methods of scenario analysis (preparing for future response based on multiple potential outcomes) in the marine conservation and fisheries sectors in Canada.

Colleen Petrik wins PICES 2016 Science Board Best Presentation Award

Nereus Fellow at Princeton University Colleen Petrik won the Science Board Best Presentation Award at the North Pacific Marine Science Organization (PICES) annual meeting, held in San Diego, from November 2 to 11. She gave a plenary presentation on “The response of fisheries production to natural and anthropogenic forcing: past, present and future”, using the results of the model she developed with her Nereus research.

Green College seminar: Impacts of climate change on contaminants in fisheries

“Our energy choices have ramifications for many other types of pollutants,” said Elsie Sunderland, Associate Professor of Environmental Science and Engineering at Harvard University and Nereus Program collaborator. “Hydroelectric: when we flood our reservoirs we actually cause a dramatic pulse in methylmercury production, which is neurotoxic, and we also cause a pulse in CO2 and methane.”

INFORMATION SHEET: Slavery fisheries and Japanese seafood consumption

Thai, Burmese, Cambodian, and Indonesian men are subject to forced labor on Thai and foreign-owned fishing boats. Some remain at sea for several years, are paid very little or irregularly, work as much as 18 to 20 hours per day for seven days a week, or are reportedly threatened, physically beaten, drugged to work longer, and even killed for becoming ill, attempting to escape, or disobeying orders.

This information sheet looks at Japanese seafood imports and locations of forced and child labour.

Global Atlas of Marine Fisheries

For the past ten years, Sea Around Us has been constructing a more accurate view of world fishery catches, finding, among other things, that 30% of catch goes unreported. Now the work of 400 researchers from 273 countries, led by Daniel Pauly and Dirk Zeller, has been compiled in a comprehensive 520-page book called the Global Atlas of Marine Fisheries.
