More information about fishing.
Will the Pacific see conservation happening as it had to do in the Atlantic? The case of the tuna species there, in past present and future scenarios, leaves us wondering which attitudes reign in Korea, Japan, the USA and Mexico.
When can cod and tuna finally be left to produce a viable population? Without science, it is highly improbable we would have any left. In the Pacific, the situation is that less industrial fishing leaves locals to decide just how they like their fish and chips.
Americans worry about how the Pacific can be crossed by cesium-134. Tuna is possibly the greatest concern, but dont worry. Keep on noshing that sushi!
Many levers have been tried in establishing conservation aims. This series of really cold swims will test to see if the Antarctic can be maintained as a pollution and overfishing-free zone. That is certainly the way it should remain, but greed can always be counted as a major factor in human affairs.
The damage afforded by our emissions on changing the climate are compounded by large-scale pollution of the oceans and overfishing as if they are going out of fashion. And they are! The realisation here is that we are going to lose many more marine plants and animals than we thought, unless the stress of conservation shifts to less-known animals and plants.
To observe the cuttlefish or the squid is to see wonderful colour change ability. Maybe now, we can find out how exactly they use this ability in mating of deterrence of predators. Video has been used now to follow animals clandestinely, although one cam was noticed and ripped off by other squid!
Long suspected of murder, the grey seal is exposed as a regular killer of the smallest whale, the porpoise. They have recently started seeking the blubber from the porpoise, possibly after large numbers of drowned porpoise were made available after their dumping from fishermens bycatch.
The loss of orcas in Puget Sound and the killing of 1500 pilot whales annually in the Faroes is a sign we need more vigilance. People are polluting, overfishing and still attacking the sea and its creatures. The Faroese do not need food, otherwise they could gladly eat whales. Like too many hunters they are retaining bloodthirsty habits that have no place in society, alongside genocide and other bloodlusts.
The Antarctic is, or was, the unspoilt continent. To preserve some of its pristine condition, it should be quite easy to keep the oil, the mining the fishing and, most of all, the greed at arms length. For the sake of penguins and healthy, sustainable fish stocks, we have to start this difficult process.
The old story is about to repeat itself again. Small species with a limited niche, Chinese medicine again an ugly influence. The Mexican government and all available help will be needed to beat this extinction, visibly obvious as a fishing season approaches.A Conservation Challenge indeed!
When fisheries policies change, we have rarely managed to avoid mistakes in estimating the effects. Here we have happy gannets but when fishing discards are prevented, the rocky islands around Ireland and the rest of Europe will be less populous than before.
After the World Ocean Summit, the long term future is not assured. We can hope that the more positive nations move on aggressively, to combat those people and industries who would violently continue their unthinking habits. Some fishing and eating habits became obsolete when so many species, great and small, started to disappear
Far away in the Antarctic, life for the albatross is hard. Fishing vessels are sources of food, but the prime fishing is found in productive shallow seas near islands. The personalities of these birds have always been intriguing, and now we have a start on discovering more about their lives.
Can we really be useful to our coastal fauna, by providing their old nurseries and larders in the form of algal forest, as well as artificial reefs and controlled fishing?
With populations in the Atlantic very low, the bulk of the Japanese expensive taste for tuna is catered for in the distant Pacific islands. The need is to regulate these small ports and stop the rot before 2 more species become simply another gap in the ecosystem.
When a squid attacks, we think we know what they are up to, but here's one that has a truly novel approach, and a lot of technique, it seems.
When we assess the ways in which bluefin tuna have been treated over the past two decades, there will be a need to apply the hard lessons of failure and irresponsible fishing.
The thresher shark is yet another unique and ancient type of shark with unique abilities. Now vulnerable, thanks to 'shark-fin removers' as well as other fishermen, we have to understand its modus operandi in order to save the species.
Western Atlantic bluefin tuna numbers are severely depleted. Bluefin tuna have been overfished for decades due to its popularity in sushi delicacies.
Off the coast of Scotland are northern coral reefs that have now been discovered to be the nurseries of catsharks. Scottish scientists are now hoping to protect these precious areas as reserves, with only line fishermen allowed.
The sad situation regarding fish in fished-out Europe is showing a glimmer of light, though unemployed fishermen in economically-struggling areas will not easily take the bitter pill. We can only hope that logic wins, for once.
Hector's dolphins off New Zealand are being caught in gill nets used by trawlers fishing illegally inside a sanctuary.
The variety of fishing techniques used in the Pacific means that BET (bigeye tuna) biomass is soon going to dip below the maximum sustainable yield levels.
The little-known but well-recorded vampire squid is in fact the sole, relic descendant of a special cephalopod group. They live in the science-fiction-sounding OMZ.
Fishing gear and methods such as longlines, trawls, gillnets and other types of gear catch sea turtles unintentionally, as bycatch. Sea turtles lives reflect the depths and mysteries of the ocean world - their survival is critical to the health of our oceans and environment.
Stocks of Bluefin tuna are plummeting from over fishing. Tuna numbers and dangers from contamination are why you shouldn't eat Bluefin tuna.
Dr Ateweberhan, a marine scientist, spent the last two months in Western Ghana as part of a research team conducting marine ecological and fisheries surveys.
Satellite tagging is becoming fascinating in some animals, none more so than the endangered bluefin tuna. 132 juvenile tuna fish were tagged and implanted, then followed for four years.
Northern elephant seals migrate throughout the north-east Pacific. They are foraging there on populations of squid and fish. 297 elephant seals were were tagged and tracked from 2004 to 2010.
Fish with us, it's better! New research illustrates how bottlenose dolphins and mullet fishermen cooperate in Laguna-Santa Catarina, Brazil; highlighting how learning can enhance social behaviour.
Marine scientists have delved back 700 years to find out how fishermen achieved high yields and sustainable management - and says they provide lessons for us today.
A new study has shown how co-managed fisheries prove quite successful. To protect fish stocks from overfishing co-management schemes have been evaluated by the Wildlife Conservation Society and various universities.
Squid have evolved unique vision separate from the fish's movable lens and our own squeezable lens. Giant and colossal squid have enormous eyes, which have evolved to help them avoid predation according to new research.
The Prince of Wales has warned that fisheries must adopt more sustainable management practices or the alarming decline in global fish stocks will worsen and could become irreversible.
It's a new model of how bluefin tuna (Thunnus thynnus) influence each other's populations from both sides of the ocean. This is one of the largest and fastest bony fish on earth and presents a special predatory function over many smaller fish and squid.
New research on female guppies and their responses to mating. A recent study from the universities of Exeter and Copenhagen examined the mating behavior of the Trinidadian guppy, a species of freshwater fish you might know very well if you're one of those people who like to keep aquariums at home.
Guppies have been evolving for at least half a million years and yet there is one characteristic of them that seems to have remained exactly the same where the male guppies are concerned.
Bluefin tuna can travel 100 km per day, so the NASA's satellite coverage of the whole of the Mediterranean is entirely appropriate. Bluefin feeding and potential spawning habitats are mapped accurately with the help of data over the last ten years.
Something doesn't smell right with the EU Common Fisheries Policy. Analysis of European decision makers and mathematical models of the likely outcome of current policy has produced alarm bells for fisheries.
The sharks of the North Atlantic and elsewhere have been caught by mistake (shark bycatch) for too long. With 860,000 blue sharks alone being killed and discarded and an equal number caught deliberately. PEW have set out some changes that could help mitigate these devastating losses.
New UK trials have made the first attempt in leading the way on putting a stop to the thousands of tonnes of discarded bycatch, dead fish, that are completely wasted and thrown back into the sea every single day across the EU.
141 per cent of the permitted eastern Atlantic bluefin tuna catch has been landed in 2010. This figure is another 10% higher than the previous survey in 2008 and still takes no account of missing black market bluefin. Bluefin is a greatly-endangered giant fish, designed to predate rather than be predated.
The President of the Marshall Islands, Jurelang Zedkaia, declared the world's biggest shark sanctuary on October 2nd. The parliament or Nitijela unanimously passed a law prohibiting commercial shark fishing in the two million km2 piece of ocean surrounding the Pacific islands.
In the UK, TV chefs have done wonders to energize the debate on the peril that the world's fisheries and ocean's are in. Now it must be over to the masses to turn their purchasing-power into real-world change, that can stop the plunder of the world's marine resources.
New research indicates that sharks and marine turtles are in trouble around the globe. Scientists offer some new insights into possible methods for reversing these trends. Pressures on marine environments - from rising sea temperatures and overfishing to pollution and oils spills - is taking an increasingly heavy toll on a variety of marine species including turtles and sharks.
A study has highlighted flaws in fisheries' assessments of the health of fish populations. Brad Erisman, a Scripps researcher, and colleagues have been looking at the populations of bass, using a combination of data sources.
Europe's Atlantic fringes have seen significantly warmer waters for the last 30 years and the fish are responding, says a report on fishery studies in the NE Atlantic. More faster-breeding, warmer-loving fish, and fewer cold-water species are part of the 'swings and roundabouts' pattern being picked up by the study published in Current Biology today.
A coalition of conservationists and scientists are at the UN this week to argue that the organisations own rules on sustainable fishing in our deep oceans are being routinely flouted by member states.
Experts agree that a global partnership is needed to combat 'pirate' deep sea fishing. Although only 1% of the world's seafood may come from deep sea fishing, the damage done to the sea floor by trawling has a far larger impact on deep sea ecosystems.
Researchers have linked declining wild salmon populations with infestations of parasitic sea lice emanating from intensive salmon aquaculture in the Broughton Archipelago in Canada. After a number of contradictory reports, scientists have correlated sea lice outbreaks with the depletion of wild salmon populations of pink and coho salmon.
Not all MCS-labeled fish turn out to be true to their sticker, according to a new study on the make-up of the Chilean sea bass, commonly found in US grocery stores. Many of the fish labeled as sustainably-sourced in fact comes from different South American fisheries, or even from oceans on the other side the world, say the authors of the work published in Current Biology.
Tuna and billfish are among the most economically important species in our seas, however, they are also suffering at the hands of overfishing and according to the first study of its kind on global populations, seven species are now 'threatened' by fishing.
An endangered species of salmon are not being given adequate protection by the American government a court has ruled. Delighted conservation, fishing and tribal groups now want action they say will save the salmon species and provide thousands of jobs.
A new patent developed by a scientist in Israel allows for fish farms to minimize or even illiminate water pollution and fish contamination. According to a report by the UN Fish and Agriculture Organization, aquaculture (artificially grown seafood) provides over 47% of total world supply of seafood.
The fish on which we most rely are under threat of extinction says a new survey of scombrids, which include mackerel and tuna - overfishing, pollution and destruction of ocean habitat is the cause say the compilers of the Red List of Threatened Species.
Shark Finning: When those aiming to save the shark are up against bloody trade making big money, seas and fisheries that are not policed and a community wanting to defend its cultural heritage, how can they win the battle? By turning the shark fin soup bowl into a dining room outcast.
Fishing for Food is a Human Right! The denial of access to the subsistence fishing spots by the Durban authorities has impacted gravely on lives of Durban's subsistence fishers, a definitive case of 'The Inequality of Survival'.
Propoals to reform the EU Common Fisheries Policy hope to reduce over fishing, ban the process of discarding unwanted fish and conserving existing stocks. After some years of operation it became clear that the policy was not achieving its key objectives, with overfishing continuing and fish numbers declining, some almost to the point of extinction.
The first comprehensive assessment of tuna and billfish has put 5 of 8 tuna species on the Red List for threatened or endangered animals and the IUCN is warning that Bluefin tuna are particularly vulnerable to vanishing, without the closure of fisheries. The report, out today in Science puts part of the blame on the higher prices of the remaining numbers of tuna and marlin.
The Bahamas has outlawed the commercial fishing of sharks. The islands' government announced yesterday that the 630,000 square kilometers ( or 243,244 square miles) of the countrys waters are now off limits to commercial shark fishing.
Academics don't often call for less study, but experts on the Great Lakes in North America warn that unless radical action is taken quickly, Asian carp will cause terrible damage to native species and fishery economies. The study calls for action and even calling in the army in the shape of the U.S. Army Corps of Engineers to help separate the lakes from the carp's Mississippi home.
The numbers of albatross and other sea-birds drowning after being snared by longline fishing hooks is three times higher than thought - at 300,000 per year. The new number in a study published in Endangered Species Research, is all the more shocking because measures to make longline fishing safe have been proven to work.
Ocean2012, the marine conservation group, launches its 2nd annual European Fish Week, hoping to influence decision-makers looking to the future of EU fishing policy. Ocean2012 is asking us to go back to the future, to find inspiration in the past in order to revitalize our oceans in the future - and bring them back to their former flourishing state.
The US Government has decided that while Atlantic tuna stocks are under pressure they are not yet in danger of extinction, although the ongoing effects of the Deepwater Horizon spill may change that. Currently the western Atlantic, eastern Atlantic and Mediterranean populations of blufins are to be designated as 'species of concern.'
Around half of all the fish caught in the North Sea are thrown back to die. TV chef and food campaigner Hugh Fearnley-Whittingstall is campaigning to reform the EU's fishery discards policy to end this terrible waste.
As seas warm the northern abalone - a noted delicacy and important to coastal economies in north America - is likely to suffer further losses to add to the damage done by overfishing and poaching. The northern abalone lives along the North American west coast from Baja California to Alaska and is prized as a delicacy
In recent days, WWF and Greenpeace issued a call for the suspension of bluefin fishery in the Mediterranean, as tuna boats headed for the Libyan waters for the fishing season due to open Sunday 15th May. It looks like the Mediterranean tuna fleet is likely to exploit the possibility of unregulated hauls in Libyan waters.
Existing protected areas are inadequate in safeguarding turtles from fishing nets, a new study has found. This is the first comprehensive tracking study of olive ridley turtles during the nesting season, using satellite transmitters to follow 18 female turtles.
The world's two largest economies have announced cooperation on fisheries and greenhouse gases. They hope to stop unregulated fish stocks from going on sale, monitor the management of threatened species and to reduce the toll of protected marine animals like sea turtles.
Small fry may be at greater risk from population plunges than the big predatory fish, says a study out today in Proceedings of the National Academy of Sciences. That flips the convention that has fish species at the top of the food pyramid as most vulnerable to pollution and overfishing pressures; anchovies and sardines need looking after too.
Scotland's first marine reserve, established only two years ago in Lamlash Bay in Arran is already showing positive benefits as the seabed recovers from the impact of destructive scallop dredging. More juvenile scallops are thriving in the no fishing zone, and adults are growing bigger and will seed surrounding areas.
Our insatiable appetite is devastating fish populations in the Mediterranean. The report documents the first comprehensive assessment of native marine species for an entire sea; an enormous undertaking. Almost half the species of Mediterranean sharks and rays are threatened, in addition to at least 12 other fish species. The main threats to fish populations in this region are - predictably and sadly - overfishing and pollution.
According to an April 2011 report released by Greenpeace, the earth's oceans are in jeopardy due to the devastating effects of overfishing and bycatch. DThe report's findings indicate that careless industrial fishing practices continue to be a large part of our ocean's troubles, and are now responsible for reducing populations of ecologically vital animals like cod, sharks and tuna by up to 90 percent.
Hundreds of thousands of seabirds are dying as a result of being caught in commercial fishing longlines and now a research team may just have the answer to reducing the seabird bycatch. Traditional fisheries bycatch models are based almost entirely upon fixed maps of historic bird migration data and past fishery information and there is no consideration of more dynamic factors.
WWF forms new partnership with handline fishers in the Coral Triangle in an effort to lead them into the sustainable fishing market. Our oceans have long been regarded as limitless suppliers of food, but the technological advances in our fishing techniques allow us to harvest fish at an unnatural and devastating rate.

An international animal welfare organisation has launched a competition to reduce the amount of sea creatures accidentally caught in fishermen's nets, known as by bycatch. The competition is offering a first prize of $30,000 and two $10,000 runner-up prizes. Additionally, working with the International Seafood Sustainability Foundation (ISSF), the competition offers a $7,500 prize for the idea that will reduce the amount of bycatch found in tuna fisheries.
EU takes action after Hugh Fearnley-Whittingstall 'Fish Fight'. No, Hugh Fearnley-Whittingstall hasn't been getting in the ring with a heavyweight cod! Unless you've had your head in a bucket of seawater for the past couple of months, you can't have failed to notice Hugh's fight to reduce 'discard' on trawlers.
It seems fish have to put up with more than just a voracious fishing industry and oceans becoming more acidic. Noise pollution, such as that from powerboats and jet skis, is also causing them to be distracted from eating. More research is needed to quantify the effects on fish populations, long-term.
Reefs at Risk Revisited finds that three quarters of the world's coral reefs are under threat. Reefs at Risk Revisited, a World Resources Institute (WRI) project, is a groundbreaking analysis of threats to the world's coral reefs. This comprehensive assessment found that three quarters of the world's coral reefs are under threat from pollution, overfishing and climate change.
The longstanding connection between nature conservation and hunting and fishing in the US has been confirmed with the announcement of a $749 million fund for wildlife projects. US Secretary of the Interior Ken Salazar said that the money was coming from excise tax revenues generated by sportsmen and women and would go to state and territorial fish and wildlife agencies.
People are eating the oceans dry of the big predatory fish leaving the smaller fish to claim the waters. Scientists have confirmed that with humans overfishing the big predatory fish at the top of the food chain the smaller fish are thriving in their new niche. People's desire to eat the big fish species, such bluefin tuna, cod and grouper, has meant their numbers have reduced worldwide by a massive 60 percent.
The Japanese government has announced that they have decided to bring this year's Antarctic Ocean whaling season to an early end. A statement by the Japanese Ministry of Agriculture, Forestry and Fisheries they said their whaling fleet will be returning home shortly as a result of the ongoing harassment that they have been receiving from the anti-whaling activists in the Antarctic Ocean, naming the vessels run by the Sea Shepherd Conservation Society.
New research suggests that a cyclical weather pattern in the Atlantic Ocean is responsible for the recent reported decline in striped bass populations. The striped bass was once one of the success stories of conservation. Previously overfished, then serious catch limits were put in place and the population of striped bass was able to recover: fishermen where then once again able to fish for these large, trophy fish along the East Coast of America.
An average of five humans have been killed by sharks each year since 2000, yet every year we kill up to 75 million sharks for their fins, used in Chinese shark's fin soup, and as bycatch in our fisheries. Shark finning has expanded globally due to rising demand by affluent Chinese for the high status shark fin soup. Retailing at about US$ 430/kg in Hong Kong the trade is a lucrative one for fishermen. Finning is inhumane and cruel in the extreme.
A new study shows that increasing water temperature in the North Sea is pushing zooplankton species further north, resulting in less food for young cod. Global warming will adversely affect the recovery of the Atlantic Cod in the North Sea, a new study shows.
By scrapping the centralised policy of quotas, Europe's lawmakers can to boost the sustainability of the fishing industry, it is being argued. Since the Common Fisheries Policy (CFP) came into effect to regulate the fishing industry across European Union states back in 1970, it has been widely criticised for failing to keep stocks healthy and to protect livelihoods.
Australian Government begins review of sustainable forestry. The Australian Government has stepped up its efforts to ensure the sustainability of the country's forest plantations. Officials at The Department of Agriculture, Fisheries and Forestry (DAFF) have commissioned a review of the codes governing plantation farming across the country.
A three-year dip in Bering Sea temperature has caused a change in the distribution of the staple food of pollock. The Bering Sea is considered to be one of the world's most productive fisheries and its northern portions are the home of sea ducks, grey whales, bearded seals and walruses, but a 30-year warming trend has been bad news for those animals that are adapted to a cold-water environment, causing them to migrate further north.
Large, oceangoing fish like the shark have been in steady decline for years, victims of poor regulation and overfishing by big industrial fleets. But now some reprive seems to be in sight thanks to a US law. The US Congress approved a bill prohibiting shark finning in all United States waters.
Satellite tracking technology has helped British scientists map the route taken by female leatherhead turtles for the first time. The marked decline seen in global populations of leatherback turtles can be partly attributed to the fact that their annual migratory routes force the animals to run the gauntlet of long-line fishing boats in the middle of the Atlantic Ocean.
In a bold move, the Senate of the Commonwealth of the Northern Mariana Islands has voted to prohibit all shark finning in its waters. Sharks living in the ocean around the Commonwealth of the Northern Mariana Islands (CNMI) have suffered from intense overfishing and poaching for their valuable fins. Sharks in particular are vulnerable to illegal fishing because, as a species, they reproduce very slowly.
The Centre for Biological Diversity in Australia has appealed to the world to boycott bluefin tuna sold in sushi restaurants and in just over a week they already have 20,000 signatures from 91 countries. The price of bluefin tuna has soared this year to over US$170,000 for just one fish. This has created a significant increase in illegal bluefin tuna fishing and as a result there are now grave concerns that the bluefin tuna population is close to extinction.
A recent international meeting in Paris has agreed to increase global protection for sharks and sea turtles; but the bluefin tuna appears to have lost out. Representatives from 48 nations recently met to discuss the fate of fishing quotas in the Atlantic and Mediterranean seas.
The illegal trade of Patagonian Toothfish is a major global industry; now the latest measure in fighting the toothfish pirates is being put in place. In the past, authorities have undertaken marathon chases of toothfish pirates across territorial waters often ending without any prosecution.
The European Commission has announced that they plan to totally remove shark finning from EU waters, and prohibit EU fishing vessels from shark finning anywhere in the world.
A recent report highlights concerns that parasitic sea lice found in fish farmed salmon is now plaguing wild salmon populations. The authors of a report recently published in The Canadian Journal of Fisheries and Aquatic Sciences conclude that salmon farms are the main source of the sea lice that have been discovered on wild salmon throughout the coast of British Columbia.
