Many wild fish in Québec have parasites. Is this necessarily a bad thing? How can we limit the proliferation and spread of specific harmful parasites?

Using cameras and trackers attached to Australian sea lions, we explored previously unmapped ocean habitats off the South Australian coast. The data also fed into predictive computer models.
Recording soundscapes in seagrass is useful because it allows researchers to detect creatures that can’t be seen, because they’re camouflaged, hiding or nocturnal.
Although marine conservation around Britain has shown some success, many of the tools that are in use today are irrelevant, or missing entirely.
Increasing coral bleaching will be worst for the most biodiverse reefs along the equator, impacting the livelihoods and nutrition of the people who depend on them.
Sea cucumbers have been overharvested for centuries. At the same time, coral reefs have declined as well. Research suggests that saving the former may help restore the latter.
Marine protection represents our best strategy to reverse declining biodiversity. But protected areas also provide a low-tech and cost-effective way for the fishing industry to safeguard stocks.
Governments all over the world are propping up overfishing. Now scientists have penned an open letter calling on trade ministers to implement stricter regulations against harmful fisheries subsidies.
In the Mediterranean, heat waves are decimating underwater forests that are essential to ecosystems. The gorgonians seem to be better able to resist in the depths, but this refuge may only be temporary.
Photogrammetry, a technique where 3D information is extracted from photographs, is reducing the guesswork in counting – and understanding – the world below the ocean surface.
When ships sink, they add artificial structures to the seafloor that can quickly become diverse, ecologically important underwater communities.
Blood isn’t sterile, and analyzing the bacteria in it could help assess the health of fish and prevent the collapse of their populations.
Thousands of pearl octopuses were discovered in 2018 lining thermal vents near a deep-sea volcano. Researchers now know why octopus moms gather there.
Open ocean sharks are globally threatened with extinction. Knowing where they are helps us protect them. Here, new research into silky sharks reveals priorities for conservation.
Rhino rays, which are close relative of sharks, are some of the most fascinating – and most threatened – fishes that you’ve never heard of.
China and Russia have been blocking international plans to protect marine life in East Antarctica. Will next week’s special meeting in Chile break the deadlock? Australia hopes so.
The first comprehensive audit of marine life around Australia, deploying an army of volunteer research divers alongside scientists, has revealed southern reefs are suffering the most.
The Soviet Union was a latecomer to industrial whaling, but it slaughtered whales by the thousands once it started and radically under-reported its take to international monitors.
New data shows coral cover in the Great Barrier Reef is at a record high, despite a disturbing decade of marine heatwaves, cyclones and floods. While the data is robust, it can be deceptive.
The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.
