In the 1800s, Americans hunted many wild species near or into extinction. Then in the early 1900s, the US shifted from uncontrolled consumption of wildlife to conservation. Could Asia follow suit?
Fish must be released into good quality water, with suitable habitat and lots of food. These conditions have been quite rare in Murray Darling rivers in recent years.
Biodiversity is often highest in places with human activity. The fishing industry has shown we can often have it both ways: maintain important livelihoods while protecting precious marine life.
Without understanding which fish species and habitats local fishers rely on, export bans can do more harm than good.
Regulations have lowered mercury emissions globally, but the risks to ocean ecosystems and human health may be getting worse.
Scientists are uncovering the secrets of a giant undersea rock shelf, parts of which lie four kilometres below the ocean's surface.
It's possible for local fishing communities to have a say in managing the system they work in.
Fishers who hunt wild tuna use fish's natural attraction to floating objects to lure them to known positions near GPS-equipped rafts. However, these rafts are attracting increasing concern.
Monitoring the timing of recurring biological events is key to understanding the effects of climate change.
Fish can't read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.
As the oceans warm, fish are moving to stay in temperature zones where they have evolved to live. This is helping some species, hurting others and causing a net reduction in potential catch.
South Africa's annual sardine run is occurring increasingly late, and there have been instances where it doesn't happen at all. Here's why.
Even the remote open ocean offers no escape from industrial fishing for sharks.
Earth-orbiting satellites and AI tools can track fishing vessels around the world.
Strictly enforced no-take marine areas benefit everyone, from the fish to fishers.
They swim, they eat, they multiply.
The fish at your favourite lake may be outsmarting you.
North Atlantic right whales are headed toward a traumatic extinction, but could rebound if humans can get out of their way.
To ensure overall biodiversity, the intensity and impact of small-scale fisheries' methods needs far more attention.
The current system drives social injustice and environmental destruction, a new approach to address both is called for.
