Victoria's biggest-ever reef restoration project is underway, in attempt to restore the once abundant populations of native oysters in Port Philip Bay.
Pyrosomes were first seen on the Oregon coast in 2014 and every year since. Recently they have been reported in Washington, BC and Alaska. These weird organisms that resemble large pink thimbles, could signal really big changes in the marine ecosystem.
The so-called 'warm blob' of water in the North Pacific has brought unusual plankton, which lack the nutrients wild salmon and other marine animals count on.
A harmful algal bloom, better known as a red tide, has been building up at Elands Bay on the West Coast, about 220km north of Cape Town.
Swarms of giant jellyfish are floating along the coastline of the Sea of Japan, and the damage they may cause to fisheries is feared to be the worst in more than a decade.
The Whatcom County Health Department is warning residents that PSP a common biotoxin is now at potentially lethal levels in mussels harvested in Bellingham Bay.
No one really knows why algae put so much effort into making poisons. Alexandrium makes saxitoxin, and causes PSP. Another algae called Pseudo-nitzschia produces domoic acid, the source of amnesiac shellfish poisoning.
On a more helpful note, fish farts also are giving researchers and managers clues about fish distributions.
Sea star wasting disease, a type of densovirus, reduced the count of sea stars in Kachemak Bay from 180 last spring to a measly five this year.
Kachemak Bay has witnessed massive die-offs of sea stars, murres and razor clams. Whats going on?
Warm water threatens marine habitats off the coast of BC
Last summer while scoping for marine invasive species we found the invasive colonial tunicate, Didemnum vexillum also know as marine vomit.
Aerial surveys show almost no reefs across a 1,200km stretch escaping the heat, prompting scientists to call for urgent action on climate crisis.
They are brightly coloured, beautiful and hungry — tropical fish and sea urchins are thriving in southern waters warmed by climate change. But now they are devastating kelp forests already knocked around by marine heatwaves.
Of all of the aquatic animals that could be collected in a gillnet on the Kenai River, crawfish are some of the least likely. Why? Because they do not naturally occur in the Kenai River or any other river in Alaska. Unfortunately, crawfish have been collected from the lower Kenai River twice in the last four years, and both times they were leftovers from someone’s dinner.
Summer commercial Dungeness crabbing was well below average in Lynn Canal, with fishermen hauling in an estimated 105,000 pounds this year compared
