Echo-sounding Techniques For Studying The "capturability" Of Tuna
In tropical oceans, it would be useful to know, for a given ecosystem, the distribution of tuna, which are vital resources for many countries. As part of a research programme, Ecotap (1) conducted in the French Polynesian Exclusive Economic Zone, scientists have used an acoustic probe to study directly and simultaneously the distribution of... view more...

Thieving whale caught on video gives rare clues about hunting strategy, sound production
For decades scientists have been intrigued by the variety of sounds emitted by sperm whales, partly due to a popular theory that suggests that the sounds might contain information about the animals' size. view more (2009-05-22)
World's largest marine protected area created in Pacific Ocean
The small Pacific Island nation of Kiribati has become a global conservation leader by establishing the world's largest marine protected area - a California-sized ocean wilderness of pristine coral reefs and rich fish populations threatened by over-fishing and climate change. view more (2008-02-14)
Spring fishing season arrives... and with it, amphibian diseases
Waterdogs, they're called, these larvae of tiger salamanders used as live bait for freshwater fishing. view more (2009-04-08)
Evolving From Marine Nature Reserves Towards Biotechnoparks
In near future, marine nature reserves will execute an important historic mission: they will become the crystallisation centres, around which territories should appear to perfect optimal methods for protection and utilization of maritime resources. Such conclusion was made by the leading preserving specialists, invited by WWF and the Moscow UNESCO... view more... (2003-12-05)
Scientists Discover Stinging Truths About Jellyfish Blooms in the Bering Sea
A new study helps explain a cyclic increase and decrease of jellyfish populations, which transformed parts of the Bering Sea--one of the U.S.'s most productive fisheries--into veritable jellytoriums during the 1990s. view more (2008-05-30)
Health of Acehnese reefs in the wake of the tsunami shows human impacts more harmful
According to research reported this week in Current Biology, tsunami damage to coral reefs closest to the epicenter of the 2004 Sumatra-Andaman earthquake was occasionally spectacular, but surprisingly limited, particularly when compared to damage from chronic human misuse in the region. view more (2005-11-08)
Stray penguins probably reached northern waters by fishing boat
Guy Demmert got quite a surprise when he hauled a fishing net into his boat off the coast of southeast Alaska in July 2002. There among the salmon, in living black and white, was a Humboldt penguin, thousands of miles from where any of its kind should have been. view more (2007-06-06)
Anchovies In The Net: Concealed Identities Revealed
For those who delight in eating Mediterranean anchovies, the taste of inshore varieties has long been preferred to that of the open-sea kind. An IRD researcher has shown that this organoleptic difference coincides with a real biological distinction. In the Mediterranean Sea there is not just one species of European anchovy but two, each occupying... view more... (2003-09-24)
Forget cooking"¦
There are some preferences among the consumers that establish the tendency in the development of new formulations and technologies of food preserving. Those preferences are toward food of easy and rapid preparation, less severely processed (preserving vitamins and nutrients), natural (without preservatives and other artificial additives), fresh,... view more...

Study finds high mortality of endangered loggerhead sea turtles in Baja California
Along the southern coast of Baja California, Mexico, scientists have been counting the carcasses of endangered sea turtles for a decade as part of an effort to assess and eliminate threats to loggerhead sea turtle populations. view more (2008-10-15)
FRENCH POLYNESIA : BETTER KNOWLEDGE OF TUNA RESOURCESFour years of research (1995-98) involving IRD, IFREMER and SRM, the Ecotap programme (study of tuna behaviour by acoustics and fishing methods) have now yielded their results. The aim was to unde
Up to the early 1990s, local tuna fishing was run by small traditional operations and was limited to coastal waters. These concerns exploited only a tiny proportion of the EEZ and the target species were those inhabiting surface waters such as the bonito (yellowfin) which have low commercial value. The open sea was prospected rather by Asian... view more... (1999-10-28)
Can Certain Metals Repel Sharks from Fishing Gear?
Sharks in captivity avoid metals that react with seawater to produce an electric field, a behavior that may help fishery biologists develop a strategy to reduce the bycatch of sharks in longline gear. view more (2008-04-23)
4 years after tsunami: Corals stage comeback
A team of scientists from the New York-based Wildlife Conservation Society (WCS) has reported a rapid recovery of coral reefs in areas of Indonesia, following the tsunami that devastated coastal regions throughout the Indian Ocean four years ago today. view more (2008-12-29)
NYU, Scripps finding offers new path for treatment of diabetes
Researchers at New York University and the Scripps Research Institute have discovered a new enzyme, GAPDH, which regulates insulin pathways-a finding that offers a new direction for the treatment of diabetes. view more (2006-11-28)
Earth's Most Diverse Marine Life Found Off Indonesia's Papua Province
Two recent expeditions led by Conservation International (CI) to the heart of Asia's "Coral Triangle" discovered dozens of new species of marine life including epaulette sharks, "flasher" wrasse and reef-building coral, confirming the region as the Earth's richest seascape. view more (2006-09-21)
Ecologists warn of the dangers of GM fish
The aquaculture industry will do increasing ecological damage around the world unless urgent action is taken by national and international policy makers, a new report by the British Ecological Society has warned. The report - written by experts from University College Cork, the University of Glasgow, Germany and Sri Lanka - argues that while... view more... (2003-06-17)
Rising acidity levels could trigger shellfish revenue declines, job losses
Changes in ocean chemistry - a consequence of increased carbon dioxide (CO2) emissions from human industrial activity - could cause U.S. shellfish revenues to drop significantly in the next 50 years, according to a new study by researchers at the Woods Hole Oceanographic Institution (WHOI). view more (2009-06-18)
The precautionary behaviour of Octopus vulgaris: the biology of common octopus populations off North-West Africa
Having appeared abruptly in abundance off the Senegalese coasts in 1986, the common octopus, Octopus vulgaris, today represents the main income of 6-7000 traditional fishing concerns in Senegal. In 1998, nearly 2500 tonnes were landed generating a turnover of 3000 million CFA (French African Community) francs. So important is this fishing resource... view more... (2000-05-22)
Living Oceans Foundation leads Red Sea expedition
Khaled bin Sultan Living Oceans Foundation will lead an all-star team of scientist divers on an expedition to study the "rainforests" of the Red Sea. State-of-the-art technology will enable the team to complete years of coral reef research in just three weeks. view more (2006-04-24)
