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.

Was Assistant Minister for Agriculture and Water Resources Anne Ruston right to say that no solely-managed Commonwealth fishery is subject to overfishing?
The oceans are teeming with life and potential – but the high seas are still largely ungoverned.
The open oceans are the world's "wild west", falling outside any nation's jurisdiction. UN negotiations are aiming to draft new laws for the high seas.

There are no proper laws to combat fisheries crime. As a result, a number of organisations need to join forces to stop the problem.
While not all subsidies are bad, some are drive a ‘race to fish’.
Fish numbers are rapidly dwindling globally, and fishery subsidies are one of the key drivers behind this decline.
Small but dangerous – and coming to the New World.
A small invasive fish known as the topmouth gudgeon has already wreaked havoc on European species and its arrival to the US and South America is only a matter of time.
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.

A melting Arctic means new areas will be open to commercial fishing but scientists – and bordering countries – say they need time to study the ecological and economic risks.

Over the past 80 years sardine and anchovy have become icons of modern-day marine biology, oceanography and climate research.
Balanced harvesting adds new fish to the menu.

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.
Marine parks are valuable tools to help safeguard species such as seagrasses.

Australia's network of marine parks - a decade in the making and announced in 2012 - haven't been implemented yet, and the Abbott government has already placed the plans under review. Why the hurry?
Coral reefs and associated fisheries are of vital social, cultural and economic importance.
Scuba-diving scientists devise method for gauging the health of coral reefs – a vital ecosystem for keeping fisheries sustainable for people.
Nigel Farage raised fishing quotas on the campaign trawl in Grismby.
Anna Gowthorpe/PA Wire
UKIP leader Nigel Farage has said EU fisheries policies means the UK gives away the majority of its fish. Is he right?
Fish can suffocate too.
The oxygen is being sucked out of the ocean, and while much of it is happening far below the surface, it will still affect us above.

In a changing climate, ocean populations sometimes rise and fall in unpredictable waves. Scientists, managers and fishers must make economically and ecologically sound decisions based on long-term outlooks.
Monitoring fishing vessels could be a growth industry in the tiny Pacific island nations that govern the world’s largest tuna fishery.

A tiny handful of Pacific island nations control more than 50% of the world's tuna fishery, and their efforts to monitor international fishing vessels are set to become a major source of jobs.
