Is Science Finally Back on DFO’s Menu?

“Do you want to make a contribution to the stewardship of Canada’s three oceans and its aquatic resources?” While it might not be the most passionate and enthralling call to arms ever uttered around the globe, the majority of stakeholders in Canada’s fishing industry are in agreement that it is about time such a question has been posed to our budding scientific minds. The aforementioned question is the opening line in the Department of Fisheries and Oceans’ (DFO) new recruitment ...

What Will Climate Change Mean for Future Fisheries?

Fish by-products account for a considerable amount of waste in our province, with much of the material simply being dumped in the landfill or ocean or used as fish feed or pet food where possible. However, through bioprocessing and biorefinery there is an opportunity to generate more beneficial uses for these often discarded parts. While biorefinery and bioprocessing (ways in which to extract important factors from the by-products) are still new concepts to a very large part of the world, ...

What Will Climate Change Mean for Future Fisheries?

Climate change offers both opportunities and risks to established and emerging fisheries and aquaculture enterprises and the communities they support. ClimeFish is a four-year project largely backed by the European Union. This project has, at its core, the goal of providing sound advice to guide management decisions to ensure that seafood production can increase in areas and for species where there is potential for sustainable growth under climate change. The ClimeFish consortium of ...

What’s in a Number?

The number 111 is an interesting one. Tolkien’s hobbits call it eleventy-one and it’s how tall in feet the Statue of Liberty stands. It’s also the emergency number you dial if you’re in New Zealand. The number 111 also holds significance for DFO shellfish technician Darlene Fiander. It’s the number of days she spent at sea in 2015. If you strung all of her trips together, it would be like spending January 1 to April 21 on the water. “If I’d listened to my mother’s ...

Fishermen Feel Left Out of Fundy Tidal Process

A five-storey high, two-megawatt turbine made its way from Pictou, N.S. around the coast to the Fundy Ocean Research Centre for Energy (FORCE) site in the Bay of Fundy outside Parrsboro last month. This will be the first of two such turbines that eventually will be placed in the Bay of Fundy by Cape Sharp Tidal. This is just one project of five Fundy tidal power tests which the province feels could very well place Nova Scotia in the forefront of using electricity produced the green way. ...

Productivity and Incomes

Atlantic Canada’s capture fishing industry has had a serious productivity problem for a long time. I wrote a column about that fact a little over a year ago. This month, I will discuss the significance of the problem in determining incomes of people in the industry and the challenges it will present for the industry of the future. First, I should remind readers that productivity is measured as a ratio: It is a measure of how much of something we get out compared to what we put ...

Larval Science: Scientists Trying to Predict Climate Change Impact on Baby Lobsters

They say that no visit to Atlantic Canada is complete without a traditional feed of lobster. Few grow up here without having at least some experience with handling the delicious, if prickly, crustaceans. The species and the harvesting thereof, is part of the fabric of life in the region. But before they’re hauled up from the ocean floor for a date with a diner plate, Atlantic lobsters have to survive almost unfathomable odds in order to reach adulthood. It is in the measuring of ...

Satellite Tagging Reveals Northern Gulf Halibut Mysteries

By Dominique Robert and Jonathan Fisher Following the 2015 stock assessment, the quota for Atlantic halibut in the Gulf of St. Lawrence was set at a record high. However, the fishery is currently managed under the precautionary approach given the absence of a true abundance estimate and despite the fact that industry feels the stock has been underexploited for several years. Given this, Fisheries and Oceans Canada (DFO) scientists are planning the design of a longline survey, which ...

Solving the Mystery: Origin and Stock Structure of Capelin in the Northwest Atlantic and the Arctic

Capelin is an important forage (or food) species for several fish, mammal and seabird species in the ocean environment and is therefore considered a keystone species for maintaining marine ecosystems. The species also plays an important role in supporting commercially valuable fisheries as well as a small capelin commercial fishery. However, for decades, capelin have puzzled scientists because so little has been known about the structure of the stock over its entire range distribution. ...

Northwest Atlantic Ocean May Get Warmer, Sooner

A new study by NOAA researchers suggests future warming of ocean waters off the Northeastern U.S. may be greater and occur at an even faster rate than previously projected. Their findings, based on output from four global climate models of varying ocean and atmospheric resolution, indicate that ocean temperature in the U.S. Northeast Shelf is projected to warm twice as fast as previously projected and almost three times faster than the global average. The models were developed at NOAA’s ...
