Global climate change is altering the chemistry of the oceans. A recent study suggests that the Pacific coast's lucrative Dungeness crab fishery could suffer as ocean water becomes more acidic.
Sometimes it pays to look on the bright side.
Not all of the world's coral reefs are in dire straits. Reef fisheries tend to do better in areas with strong ownership rights, and where people are closely involved in managing their local reefs.
Hey, is there something on my back?

Tiny animals along for the ride, called epibionts, could be used as living data-loggers. Researchers can glean info from them that could help inform turtle-friendly fisheries management decisions.
Unlike clownfish (Nemo), Pacific blue tang fish (Dory) cannot be bred in captivity.
The release of the movie 'Finding Dory' comes with renewed calls to leave fish in reefs – a good idea in this case – but catching some ornamental fish can have a positive impact on reef communities.

Samal, Philippines: protected area to manage fish recovery.
The combination of local fishing rights with adjacent marine reserves creates incentives to avoid overfishing and could improve nearshore, small-scale fisheries around the world.
Time to get cracking: a Canadian research vessel in the Arctic.

Spreading fishing pressure evenly across whole marine ecosystems sounds like a great idea. But there's a hitch – we can't technologically do it, and even if we could, it would be expensive.
A golden crispy flake and chips is a classic takeaway meal. But is it a sustainable choice?
Flake is great with steaming hot chips. But what fish species is it, and is it sustainable? In Australia, it's mainly gummy shark, which is a sustainable choice. But beware poorly labelled imitations.
