Boom or bust in a jelly bloom market

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.

The Pacific islands ‘tuna cartel’ is boosting jobs by watching fish

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.
Trawling for fish? You might be setting yourself up for a paltry haul next time. Glenn Perrigo

Frequent trawling leads to skinnier fish

Trawling – dragging heavy gear over ocean bottoms in search of fish near the sea floor – is arguably one of the most destructive human practices. Removing fish from the sea for an ever-hungry, growing…

Pacific Remote Islands protection not just a drop in the ocean

This fall, President Obama signed a proclamation that created the biggest marine reserve in the world. By extending the protective boundaries around Wake Island, Jarvis Island and Johnston Atoll from 50…
Australia’s Commonwealth marine parks were designed to protect marine life, including important foraging areas for sea birds.

Marine park review looks set to repeat past mistakes

In June 2012 the Labor government announced the “world’s largest” system of marine parks, adding 2.3 million square kilometres and taking the overall size of Australia’s Commonwealth marine reserves to…
Fishing of potato rock cod is totally banned in Queensland waters. Better regulation might avoid similar bans for other species. Mark Priest

How ecosystems can keep their fish, and we can eat them too

Tighter bag limits for fishing could be the key to ocean conservation, according to new research showing that limiting fishing across entire regions can offer better protection than using marine reserves…

Ghostly art, made from debris that menaces marine life

With more than half a million people participating in last Sunday’s Clean Up Australia Day, it’s perhaps not surprising that some odd objects came to light. Not all the rubbish was on land, and not all…
If science is excluded from fisheries policy, we’re headed back to the bad old days of overfishing. Greg Bishop

Super trawler gone, but is fisheries policy in trouble?

Last week, the “super trawler” Abel Tasman left Australia, with far less fanfare than you might have expected. Many hail this as good news for Australian fisheries, but we believe it could be a great step…

Ghostnets fish on: marine rubbish threatens northern Australian turtles

Each year around 640,000 tonnes of fishing gear is lost or thrown overboard by the fisheries around the world. These “ghostnets” drift through the oceans and can continue fishing for many years. They kill…
Minister for the Environment Tony Burke and Minister for Agriculture Joe Ludwig will amend Australian law to prevent the super trawler from fishing in Australian waters for up to two years. AAP

Scientists to be called in as super trawler blocked for two years

Super trawler the Abel Tasman (formerly the Margiris) will be blocked from fishing in Australian waters for up to two years after the Federal Government announced plans to amend legislation to address…
Environment Minister Tony Burke says he can’t stop the super trawler, but will place conditions on it to help protect listed species. AAP

Super trawler protection conditions not tough enough, experts say

The super trawler Margiris is an environmental “experiment” and the conditions placed on it by the government don’t go far enough to protect dolphins, seals and other protected species, fisheries and oceans…
The Margiris is heading to Australia to catch jack mackerel, but there are plenty more fish in the sea. Richard Ling

Opposition to the Margiris ‘super trawler’ not evidence based

The Margiris “super-trawler” is heading for Australia to catch jack mackerel and associated small surface-dwelling species. It faces a lot of opposition, largely based on assertions that the vessel’s catches…
Tuna fishers agree that too many tuna are caught. But there is no good system to decide who should catch less. Justin Woolford

Who pays for conservation in the world’s biggest tuna fishery?

The world catches too many tuna. Thanks to our high levels of fishing, some tuna species are under threat. Everyone involved in the fishing industry agrees that fishing effort needs to be reduced. But…
Sanctuary: marine parks can create new ways to prevent illegal fishing. Mia Hoogenboom, ARC Centre of Excellence for Coral Reef Studies, James Cook University

Marine parks could help cut down on illegal fishing

Environment Minister Tony Burke announced the final proposed Commonwealth marine protected area (MPA) network last month. The network would be the largest in the world, covering more than a third of Commonwealth…
Reducing fishing in the Coral Sea could hugely benefit species. It’s up to the government to make sure it benefits fishers too. Sam Ilic

A solid marine parks compensation package will be good for fish and fishers

Coral Sea protection is eminently doable - but the question is, will Australia effectively manage the process of creating the largest network of marine protected areas in world? The creation of the largest…
Hard numbers: less than 1% of the world’s oceans are protected but marine scientists think 20% should be off-limits to fishing. AAP/Lloyd Jones

Marine parks: cause for optimism, but devilish details

As a marine scientist, I welcome Senator Burke’s brave decision today to roll out Australia’s marine park system. This puts us on a par with other leading nations like the US and UK who have established…
