In the spirit of reconciliation, the standout herring rebuilding plan in Haida Gwaii is restoring more than fish. Co-developed by the Haida Nation, Fisheries and Oceans Canada, and Parks Canada. it takes an ecosystem first approach that meaningfully includes Indigenous Knowledge Systems.

Sea otter pups are often born in the water and rely on their mothers from birth. A mama otter nurses her pup while floating on her back and when she needs to dive for food, she wraps the baby in kelp to keep it from drifting away. Learn more: oceana.ca/en/marine-li...

The World Cup is coming to Toronto — let’s not allow single-use waste to steal the show. More than 90% of plastic waste in Canada already ends up in landfills, incinerators or our waterways. Join #ReuseForTheWin & tell the city of Toronto we want reuse act.oceana.org/page/172451/...

🎉BREAKING: The High Seas Treaty has reached 60 ratifications — enough to enter into force! This landmark agreement creates a pathway to help protect the high seas — waters beyond any one country’s authority that cover nearly half our planet. https://oceana.ly/3VqpI2Y

It’s #InternationalMicroorganismDay. Sometimes it’s the smallest things that have the biggest impact on the world. For example, phytoplankton — a group of marine microbes that produce roughly 50% of the planet’s oxygen.

GOOD OCEAN NEWS: Canada has released its first-ever legally mandated plans to rebuild depleted fisheries. This includes 12 science-based strategies with clear timelines and targets to restore fish populations. Learn more: oceana.ca/en/press-rel...

Another heartbreaking moment for endangered southern resident orcas: an orca named J36 was seen by researchers pushing her deceased female calf in the Salish Sea on Friday, with the umbilical cord still attached, according to the Center for Whale Research. www.cbc.ca/news/canada/...

Marine habitats are vital for ocean health, climate, and coastal communities. But they're under threat. Canada must protect them before it’s too late. 👉 Sign the petition: act.oceana.org/page/176793/...

Breaking: DFO raised the herring quota mid-season in the Bay of Fundy/SW Nova Scotia without consulting the Advisory Committee. This is out of step with science advice, legislative guidance, and Canada’s commitment to rebuild fisheries. Learn more: oceana.ca/en/press-rel...

Canada generates 4.7 million tonnes of plastic waste per year and only recycles about eight per cent. With plastic on our shores and in the stomachs of our wildlife, Canada ought to pass new legislation to provide guidance and structure. Learn more: www.saltwire.com/nova-scotia/...

The second part of #INC5 opened today in Geneva. 3,700+ participants from 184 countries are gathered to develop an international legally binding treaty on plastic pollution. The session aims to approve text of the agreement for adoption at a future Diplomatic Conference: www.unep.org/news-and-sto...

Plastic treaty talks resume this week in Geneva. But with oil giants and petrochemical states pushing back, the battle over how to solve plastic pollution is far from over. Learn more www.wsj.com/articles/a-t...

Jellyfish or sea slug — can you guess? 🤔 It’s a sea slug called a Hooded Nudibranch (Melibe leonina)! Found in BC, these colorful sea slugs are predators that catch their prey (zooplankton, small crustaceans, and very small fish) using a similar method to that of a Venus flytrap.

Sea anemones look like flowers but are actually marine animals found from tidal zones to the deepest parts of the ocean. Fun fact: their mouth also functions as an anus! Waste and undigested matter is excreted through this hole.

Orcas are one of the most iconic species on Canada’s West Coast — and not all are the same. Canada has 5 distinct orca populations, each with unique diets, behaviours, and cultures. ⚠️ The Southern Resident population is endangered, with only 73 individuals left. #WorldOrcaDay #OrcaConservation

Recycling rates in Canada are failing. The vast majority of single-use items end up in landfills, the environment, or incinerators—polluting our waterways and oceans. But the World Cup is our chance to show the world that Canada can be a leader in zero-waste solutions.

It's fascinating how some of the ocean’s largest creatures survive on the tiniest prey. North Atlantic right whales, for example, feed almost entirely on krill and copepods. Every summer, they migrate along North America’s East Coast, traveling from the U.S. to Canadian waters.

Happy Hump Day! 🐋 Since the first humpback cow/calf pair of the season arrived in late May, PWWA members have reported at least 9 calves in the Salish Sea so far. This little fellow is "Stromboli", seen breaching beside mom BCX2075 "Olympus". 📷: Rachel Rodell, @pugetsoundexpress.com

Orcas found sharing food with humans for first time in new study. In many cases, Orcas tried to be persuasive, offering food even after people initially refused it, suggesting some orcas may be attempting to develop relationships with humans. www.independent.co.uk/news/science...
