In research aimed at understanding the process of fish population decline when coral reefs sustain major damage, scientists have found that big fish show a marked preference for sheltering under large, flat table corals.

Now researchers are melding building design, fish ecology and aquaculture engineering techniques into a first-of-its-kind "building-integrated aquaculture" (BIAq) model to offer an affordable, more holistic and sustainable approach to indoor fish production located close to markets and able to succeed even in cold climates.

A new report challenges previously held notions about poverty and adaptation by investigating why fishermen in developing countries stick with their trade.

It could be either, they say.

Researchers have discovered that the seals dive deeper for food when in warmer water. The scientists attribute this behavior to the migration of prey to greater depths and now wish to check this theory using a new sensor which registers the feeding of the animals below water.

The duo also discovered that Speedo's shark skin-inspired Fastskin® FS II fabric surface does not improve swimming speed, although they point out that the figure hugging costumes probably enhance performance in other ways.

A massive influx of hatchery-raised fish that return to spawn in the wild is masking the fact that too few wild fish are returning to sustain a natural population in the river.

The study, conducted in Canada's Bay of Fundy, has implications for all baleen whales in areas with heavy ship traffic, and for the recovery of the endangered North Atlantic right whale population.

Ancient giant Posidonia oceanica reproduces asexually, generating clones of itself. A single organism -- which has been found to span up to 15 kilometers in width and reach more than 6,000 metric tonnes in mass -- may well be more than 100,000 years old.

Geologists have learned that the end came slowly from thousands of centuries of volcanic activity. Fri, 03 Feb 2012 11:33:33 EST http://www.sciencedaily.com/releases/2012/02/120203113308.htm http://www.sciencedaily.com/releases/2012/02/120202164821.htm Scientists have advanced a method that allowed them to single out a marine microorganism and map its genome even though the organism made up less than 10 percent of a water sample teeming with many millions of individuals from dozens of identifiable groups of microbes. Thu, 02 Feb 2012 16:48:48 EST http://www.sciencedaily.com/releases/2012/02/120202164821.htm http://www.sciencedaily.com/releases/2012/02/120202094608.htm Around the world coral reefs are facing threats brought by climate change and dramatic shifts in sea temperatures. While warming has been the primary focus for scientists and ocean policy managers, cold can also cause significant damage. Scientists have shown that cool temperatures can inflict more damage in the short term, but heat is more destructive in the long run.

Rather, increasing scientific and media interest as well as the lack of good baseline data seem to explain the widespread perception of an increase. Wed, 01 Feb 2012 18:12:12 EST http://www.sciencedaily.com/releases/2012/02/120201181222.htm http://www.sciencedaily.com/releases/2012/02/120201181220.htm Blooms, or proliferation, of jellyfish have shown a substantial, visible impact on coastal populations -- clogged nets for fishermen, stinging waters for tourists, even choked intake lines for power plants -- and recent media reports have created a perception that the world's oceans are experiencing increases in jellyfish due to human activities such as global warming and overharvesting of fish. Now, a new study questions claims that jellyfish are increasing worldwide and suggests claims are not supported with any hard evidence or scientific analyses to date.

Sea mammals, such as whales took about half the number of generations to hit their maximum.

The increase in hunting territories available to killer whales in the Arctic due to climate change and melting sea ice could seriously affect the marine ecosystem balance. New research has combined scientific observations with Canadian Inuit traditional knowledge to determine killer whale behavior and diet in the Arctic.

Calypso while anchored on the lee side of Glover's Reef in Belize, Jacques Cousteau told Phil Dustan that he suspected humans were having a negative impact on coral reefs. Dustan -- a young ocean ecologist who had worked in the lush coral reefs of the Caribbean and Sinai Peninsula -- found this difficult to believe. It was December 1974. But Cousteau was right. During the following three-plus decades, Dustan, an ocean ecologist and biology professor at the University of Charleston in South Carolina, has witnessed widespread coral reef degradation and bleaching from up close.

With recording technology more affordable, fish sounds can be studied to test the idea that fish communicate with sound, especially those in the dark of the deep ocean.

Thu, 26 Jan 2012 13:15:15 EST http://www.sciencedaily.com/releases/2012/01/120126131511.htm http://www.sciencedaily.com/releases/2012/01/120126123712.htm Researchers have discovered that certain photosynthetic ocean bacteria need to beware of viruses bearing gifts. These viruses are really con artists carrying genetic material taken from their previous bacterial hosts that tricks the new host into using its own machinery to activate the genes, a process never before documented in any virus-bacteria relationship. The con occurs when a grifter virus injects its DNA into a bacterium living in a phosphorus-starved region of the ocean.

In a new study, researchers report that these responses are linked to a simple circuit in the brain of the sea slug Pleurobranchaea. Wed, 25 Jan 2012 13:28:28 EST http://www.sciencedaily.com/releases/2012/01/120125132810.htm http://www.sciencedaily.com/releases/2012/01/120125091059.htm Each year around 20,000 people are infected by nematodes of the genus Anisakis and suffer from illnesses ranging from gastrointestinal diseases to serious allergic reactions as a result. For the first time, parasitologists have gathered data on the occurrence of the parasitic worm and have modeled the worldwide distribution of individual species in the ocean. The resulting maps not only enable statements to be made on the occurrence and migration behavior of certain hosts of the parasites, such as Baleen or toothed whales,  but also provide conclusions on the risk of human infection.

Tue, 24 Jan 2012 15:19:19 EST http://www.sciencedaily.com/releases/2012/01/120124151945.htm http://www.sciencedaily.com/releases/2012/01/120123094801.htm Lessons from tens of millions of years ago are pointing to new ways to save and protect today's coral reefs and their myriad of beautiful and many-hued fishes at a time of huge change in the Earth's systems. Today's complex relationship between fishes and corals developed relatively recently in geological terms -- and is a major factor in shielding reef species from extinction, say experts.

Carbon dioxide concentrations predicted to occur in the ocean by the end of this century will interfere with fishes' ability to hear, smell, turn and evade predators, says a professor.

This finding is important because many species of coral are dominated by a single type of zooxanthellae.

Since winds have increased in intensity and moved to the south, the flight speed of albatrosses increased and they spend less time foraging. As a consequence, breeding success has improved and birds have gained 1 kilogram.

And every year, commercial whaling not only continues, but grows. While protests, education, lobbying and dangerous confrontations on the high seas have saved some whales, the whaling industry shows no sign of shutting down -- or slowing down. Now, an economist and two marine scientists suggest a new strategy that they believe could save whales by putting a price on them.

But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and other marine organisms. New research analyzed the role of sea cucumbers in portions of the Great Barrier Reef and determined that their dietary process of dissolving calcium carbonate (CaCO3) from the surrounding reef accounts for about half of at the total nighttime dissolution for the reef.

As greenhouse gas emissions have accelerated in the past century, the oceans have taken up about a third of the carbon dioxide produced by human activities. That excess beyond natural levels increases amounts of carbonic acid in seawater. New research shows that some organisms are already experiencing ocean acidification levels not predicted to be reached until 2100.

However, such closures have resulted in only minimal increases in herbivorous fish, which feed on the algae that smother corals and inhibit reef recovery.

Do they, indeed, avoid it?
