Mutant White Yellow Tang Shows Up at Pacific Island Aquatics

442dWhite Yellow Tang Mutant White Yellow Tang Shows Up at Pacific Island AquaticsHere’s a totally awesome fish. Pacific Island Aquatics recently showed off this amazing aberrant yellow tang, which sports a large amount of white coloration instead of the normal solid yellow we’re so accustomed to. According to information posted on Reef2Reef, the fish was collected off the south side of Kona and tips the scales at just 4.5″ in length. This is about the average size for yellow tang sold in the aquarium hobby, if not a little bit larger, but it’s one of the smallest aberrant tangs collected. This makes it far more appealing than those huge aberrant tangs we normally see.The tang will be listed at $1500 (originally $2000), but PIA is entertaining reasonable offers. This is a pretty typical price for yellow tangs with this coloration.It should be noted that this is not an albino yellow tang. Rather, it is technically a leucistic yellow tang, meaning it’s simply lacking some of its natural pigmentation. This genetic condition results in the fish exhibiting significant white coloration, and in this case a small amount of yellow on its fins and random patches on its body.

A smooth(er) transition…

lrg 97 regal angel fish 300x225 A smooth(er) transition...Getting healthy marine livestock, is one of the greatest challenges we face as aquarists. To a point, it’s not really the fault of anything but distance, which makes acclimating new acquisitions so difficult. Often, our aquariums are located thousands of miles from a specie’s natural home. Sometimes, when I consider the journey my aquarium residents have taken, it’s shocking that they even made it here alive. Even the closest coral reef, for those of us on the north east coast, is far south, stretching from West Palm Beach Florida, down to the Florida Keys. For people who live smack dab in the center of the United States, it’s much farther. When you consider that most of the species we seek out, come from tiny islands in the remote South Pacific, or Indian Ocean, you can understand why aquarium fish arrive to us, in such a stressed out state. Traveling is stressful, even on human beings. For fish, who are suddenly plucked from a rich, diverse habitat, and tossed into a tiny container, trekking thousands of miles across the planet, it’s a total change of lifestyle, within a matter of seconds. Instead of try to offer pointers on how to spot a good livestock vendors, (which requires a post of its own) I’d rather point out some often overlooked realities about marine fish, that can help us ease some of that stress, making the transition to a captive life a bit smoother. New arrivals need to be MORE

Under Water Museum Brings New Coral Life To Egypt

10613162 639552176158087 9025147345348141257 n Under Water Museum Brings New Coral Life To EgyptI have written about under water museums before on reefs.com. I don’t hide my support of what I think is an awesome blend of art and aquatica, which also promotes eco-tourism by encouraging divers to come to the area to check out the new museum sites and surrounding marine life. An Underwater museum is underway in the Red Sea, off the Egyptian Coast, as part of the Underwater Museum Coral Reef Preservation Project. The project was organized by the i-dive tribe, ‘a group of divers who are out to change the concept of diving in Egypt.’ Most peoples first thoughts of Egypt are more along the lines of deserts pyramids and tombs, not the amazing diving destination which it is.

Great Barrier Reef “Remarkably Efficient at Reducing Waves”

A team led by Dr Shari Gallop, Research Fellow in Geology and Geophysics at the University of Southampton has found that the Great Barrier Reef (GBR) is a very effective wave disturber, despite large gaps between reef sections. “A number of previous studies have investigated the attenuation (height reduction) of ocean waves as they spread across individual coral reefs. This research is unique as it looks at the impact of a large scale reef matrix, such as the Great Barrier Reef, on wave height. Such studies are important in providing wave climate information for physical, biological and planning processes in such areas” says Dr Ivan Haigh, also from the University of Southampton.  140917073108 large Great Barrier Reef Remarkably Efficient at Reducing WavesDr. Gallop concludes: “There was no evidence that in less porous areas wave heights are lessened. This is because individual reefs, like islands, cast a ‘wave shadow’ over a large area, so that a matrix of individual reefs is remarkably efficient at reducing waves.” Dr Haigh adds: “As sea level varies, due to tides and storm surges, the submergence of the reef in water also varies. Wave heights are not strongly affected by water level over the reef matrix.” Read more here!

Coral Growth Plummets on GBR

A recent study has documented a historical decline in coral growth on the Great Barrier Reef of Australia. A team led by Carnegie’s Ken Caldeira compared measurements of the rate of calcification on a segment of the GBR called Bird Island between 1975 and 1979 to those made at a neighboring Island in 2008 and 2009. The team found that the rates of calcification were 40 percent lower during the 2008-2009 period than in the 1975-1979 period. 140917121225 large 300x199 Coral Growth Plummets on GBR“Coral reefs are getting hammered,” said Caldeira. “Ocean acidification, global warming, coastal pollution, and overfishing are all damaging coral reefs. Coral reefs have been around for millions of years, but are likely to become a thing of the past unless we start running our economy as if the sea and sky matters to us very soon.” Read more here.

In Case You Missed It: MACNA Speaker Footage Available Online

10606040 10154526898905570 5266456894670676818 n 225x300 In Case You Missed It: MACNA Speaker Footage Available OnlineI know there are many of you out there who unfortunately couldn’t make it out to MACNA this year, but fear not! Bulk Reef Supply is generously providing us with footage of the first four speakers from this year. This is excellent news for me since, while I was lucky enough to be in attendance this year, I was busy working the reefs.com booth the majority of the time (and blabbing about Personatus angels). I was able to sneak away to catch Richard Ross and Rufus Kimura (two of my top 5 anticipated speakers), but missed the rest. This is the first time video of MACNA talks has been made public, and it’s a trend we hope to see continued for future conferences. Speakers available for your viewing pleasure are Lemon Tea Yi Kai (another personal favorite), Mike Paletta, Dr. Todd LaJeunesse,  and Julian Baggio. While I’d love if Julian Sprung, Sanjay Joshi and a handful of others were up for recap (ok, all of the speakers, I’d watch Rufus and Rich again, too!) this is a fantastic opportunity to catch up on some of what we missed.

Specialist Species Targeted for Their Importance

Professor David Bellwood from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) in Australia has published an international study aimed at protecting the most important species within a reef ecosystem. “What we often assume is that if we lose one species on a reef, there are many others that can step in and take over their job,” explains Professor Bellwood. However, he and his colleagues believe a different theory that involves stressing the importance of “specialist” species that play very important and specific roles in maintaining the equilibrium of a reef. 140915153832 large Specialist Species Targeted for Their Importance“It’s not about numbers of species,” adds Professor David Mouillot from the University of Montpellier who led the team. “Biodiversity is important and desirable in an ecosystem, but it is not necessarily the key to being safe and secure.” Using a parrotfish for analogy Professor Bellwood adds: “The parrotfish is a particularly valuable species. To protect ecosystems, we need to ensure that specific jobs are maintained, and that means we must protect the fish that do them.” Read more here!
