Laws protecting the critically endangered Sumatran Tiger have failed to prevent tiger body parts being openly sold in Indonesia, according to a TRAFFIC report launched today. (2008-02-13) View the full article

The Wildlife Conservation Society and the Panthera Foundation announced plans to establish a 5,000 mile-long "genetic corridor" from Bhutan to Burma that would allow tiger populations to roam freely across landscapes. Rabinowitz said corridors did not have to be pristine parkland but could in fact include agricultural areas, ranches, and other multi-use landscapes -- just as long as tigers could use them to travel between wilderness areas.

The Chesapeake Bay near Washington DC, US, is affected by multiple factors, ranging from population growth to climate variability, which will challenge the recovery of this important ecosystem. New findings released by the U.S. Geological Survey are part of a comprehensive 5-year summary of the major factors affecting the health of the Bay ecosystem and the implications for its management. Population growth and agricultural lands have contributed to an overabundance of nutrients, sediment, and contaminants entering the Bay, and loss of habitats that can retain these pollutants. Climate change and variability have caused water temperatures in the Bay to exhibit greater extremes during the 20th century than the previous 2,000 years. Sea-level rise related to climate change is contributing to the loss of vital coastal wetlands. The cumulative impact of pollutants, habitat loss, invasive species, climate change, and disease has affected the health of fish and bird populations in the Bay and its watershed.

Comparing the survival of wild salmonid populations in areas near salmon farms with unexposed populations reveals a large reduction in survival in the populations reared near salmon farms. This study shows evidence on a global scale illustrating systematic declines in wild salmon populations that come into contact with farmed salmon. View the full article

That's Ulva/sea lettuce. It's a kind of seaweed. Andf the tangs love to eat it.

Tell them the hobby keeps you at home rather than wasting time and money outside playing pool or LAN games.

Unique, collaborative ways to manage fisheries are emerging in Southern California. Currently the California spiny lobster is being scrutinized as Californians evaluate the first five years of marine reserves in the Channel Islands area. (2008-02-11) View the full article

Other tips: 1. You can use a fan to cool your tank but it'll evaporate your tank water faster so you'll have to top up with FW more often. 2. Insulate as much of your piping as possible (esp from your chiller output). 3. reduce the number of internal water circulation devices/upgrade to better ones eg. wavemakers with external motors and internal propellers.

A young scientist has discovered a previously undescribed species of parasite that infects farmed fish and produces serious disease. Single-celled parasites of the genus Spironucleus are known to produce serious illness in farmed and aquarium fish. In farmed salmon, these parasites create foul-smelling, puss-filled abscesses in muscles and internal organs. After the first outbreaks of this disease were described in farmed salmon in the late 1980's, it was assumed that the cause was Spironucleus barkhanus, which is a fairly common parasite in the intestine of wild grayling and Arctic char.

Very nice and clean tank you got there. And I like your fishes.

Rowa is short for Rowaphos. Its one of the many phosphate-removing media around.

For several years, scientists have been working to determine why so many male smallmouth bass in the Potomac River basin have immature female egg cells in their testes - a form of intersex. They are closer to finding an answer. New research shows that a high incidence of intersex occurs in the Potomac watershed at sites where farming is most intense and where human population density is highest. The study also shows the greatest prevalence of this form of intersex, known as testicular oocytes, occurs in the spring, just before and during the spawning season. A prevalence of intersex is not unique to the Potomac basin, nor is it unique to smallmouth bass. It has been documented in other wild fish populations including spot-tail shiners in the St. Lawrence River, white suckers in Colorado, shovelnose sturgeon in the Mississippi, white perch from the Great Lakes, roach fish in the U.K and Denmark, sharp-tooth catfish in South Africa, three-spine stickleback in Germany, and barbel in Italy. It has also been noted in marine and estuarine fishes in Japan, the UK and the Mediterranean. View the full article

I think it is awesome that old threads are being read and revived because it shows that new hobbyists are doing what this site is all about... researching useful information that benefits new hobbyists in their quest to setup a proper reef tank.

I have an in-wall tank with what you're asking about... you can read more about it here.

The traditional view that shrews are primitive mammals is challenged by a new study of the hunting methods of an aquatic member of the species, the water shrew, that finds it uses remarkably sophisticated hunting that allow it to catch its prey as readily in the dark as in daylight. One interesting technique is to use their sense of smell underwater by blowing air bubbles out of their nose and then re-inhaling them. View the full article

Few modern animals are as deserving of the title "living fossil" as the lowly horseshoe crab. Seemingly unchanged since before the Age of Dinosaurs, these venerable sea creatures can now claim a history that reaches back almost half-a billion years. Scientists have revealed rare new horseshoe crab fossils from 445 million year-old Ordovician age rocks in central and northern Manitoba, which are about 100 million years older than any previously known forms.

Natural processes may prevent oceans from warming beyond a certain point, helping protect some biologically diverse coral reefs from the impacts of climate change. A new study finds evidence that an ocean "thermostat" is helping regulate sea-surface temperatures. This research lends support to a much-debated theory that a natural ocean thermostat prevents sea-surface temperatures from exceeding about 88 degrees Fahrenheit (31 degrees Celsius) in open oceans. If so, this thermostat would protect reefs that have evolved in naturally warm waters that will not warm much further, as opposed to reefs that live in slightly cooler waters that face more significant warming.

To me guys, This is truly the next frontier of reef-keeping because soft corals are more beautiful and abundant than SPS corals! I may just start off on a new quest! AT
