Researchers call for action to stop exploitation of Antarctic waters
The critically important Southern Ocean is not being properly protected by its stewards, a distinguished group of scientists from around the globe have noted.
Food quality might be key for juvenile sockeye salmon growth and survival
The quality of food sockeye salmon eat along their migration routes is more important to their growth and condition than quantity, a new study has found, highlighting concerns about the effects of climate change on ocean conditions and salmon.
Expect shorter food chains in more productive coastal ecosystems
“We provided evidence for bottom-up omnivory in nutrient-rich temperate pelagic ecosystems, where food chain length is determined by the level of diatom production,” said Jacob Lerner. “This is very different from the global model for pelagic ecosystems.”
Global fish stocks can’t rebuild if nothing done to halt climate change and overfishing, new study suggests
“We are at a turning point. What we need is a coordinated global effort to develop practical and equitable marine conservation measures to support effective biomass rebuilding under climate change,” said Dr. William Cheung
BC is facing a steep decline in sockeye salmon
The sockeye population has been in decline for a century – since 1913, returns in the Skeena River have dropped by 75% – and while there are many factors at play, says Dr. William Cheung, “climate change is definitely one of them.”
B.C. ocean’s worth of almost $5 billion to GDP likely an underestimate
The ocean is very valuable to B.C., in terms of GDP, jobs, and income.
Southern resident killer whales not getting enough to eat since 2018
The animals have been in an energy deficit, averaged across spring, summer and fall, for six of the last 40 years.
New sea garden story map showcases Indigenous mariculture practices across the Pacific
The living map synthesizes information about ancestral mariculture across the Pacific Ocean and describes the work that a number of communities are undertaking to reawaken diverse sea gardens.
Decoding the secret lives of killer whales one micro-second at a time
Using methods to detect when the animals are catching prey and to model their energy expenditure will be key to understanding the differences between these neighbouring whale populations.
Expect to see more squid and less sockeye salmon on “climate changed” menus
Vancouver seafood lovers may see more Humboldt squid but less sockeye salmon on restaurant menus in the near future due to climate change.
