Ways to revert threatened status for staghorns and elkhorns drafted

Staghorn coral by Adona9 300x208 Ways to revert threatened status for staghorns and elkhorns drafted

(Staghorn Coral Photo: Adona9)

 Bad news: According to the Endangered Species Act (2006), elkhorn and staghorn corals are listed as threatened. BUT: A new draft recovery plan released by NOAA Fisheries at the beginning of the month identifies criteria that would allow the coral species to be removed from the ESA endangered and threatened species list.  (It’s so nice when someone finds a way to “reverse” damage that humans have done). Elkhorn and staghorn corals have declined by up to 97% since the 1970’s with the main causes of decline being disease, temperature-induced bleaching and storms.  This new plan lists ways to reduce threats (global threats related to climate change and local threats to the species such as habitat loss and pollution) and steps to enhance the population by putting nursery-grown corals back on the reef, as well as addressing research and monitoring. Good news!! For more information see:… More:

56e5Coral Spawning 1 for blog Coral Spawning 2014, Curacao Coral SpawningGood morning from the sunny Caribbean!! Aimee and I are walking around like zombies this morning after being out in the ocean till 11:00 last night filming coral spawning! Yes, it’s that time of the year again and for us it’s the one time of the year we love diving the most! Last night we entered the sea in all it’s darkness at exactly 9:30 and by 9:45 we saw our first eggs getting ready to be released. Aimee found this beautiful colony of Boulder Star Coral. Montastraea annularis that you see above and we decided immediately that this would be our 1st photo stop MOREMore:

Review: iQuatics Ocean Reef Pro coral salt

iquatics salt bucket 270x300 Review: iQuatics Ocean Reef Pro coral salt In this ‘hands on’ review we’ll take a look at a salt that was originally launched back in early 2014. As a relatively new player in the market place this product comes from a company already well known in the UK as an online lighting and equipment manufacturer. Touted as a synthetic blend boasting Magnesium levels of 1360ppm, Calcium 445ppm and Potassium 405ppm (levels which the company say have been slightly raised to account for depletions in home aquaria), this salt also claims to be Nitrate and Phosphate free, and fast dissolving. But does this new kid on the block ‘do what it says on the tin’? Well the first thing to look at of course is presentation and packaging and all seems fine here. The bucket is nice and sturdy and keeps the contents dry, certainly over the several weeks of or test. Our 10kg sample bucket proved a little challenging to open but after searching the web we worked out how to do it. It did require some effort to pull the lid off once the seal had been removed (instructions on the bucket would be good). We understand the larger 20kg buckets have a screw top that should prove easier to handle. On to the salt itself and we found it to mix well. Adding it slowly to a bucket of warmed RO with a TDS of zero, virtually all of the mix had More: Review: iQuatics Ocean Reef Pro coral saltMore:

“ID Please?” Misidentified Coral Turns Out to be New Species

Pachyseris inattesacoral new species article large 300x226 “ID Please?” Misidentified Coral Turns Out to be New Species, named for its surprise factor (“inatessa” translating to “unforeseen”), is a pretty freaking cool Pachyseris originally thought to simply be another genus. Discovered in the Saudi Arabian Red Sea, this endemic SPS coral sports a yellowish-brown color and wrinkly appearance. While “wrinkly” might not be the most attractive way to describe a coral, it’s actually quite striking. I’ve always been a fan of Pachyseris, though I don’t see them all that often (this isn’t because of rarity of any sort so much as the fact they simply aren’t imported all that often due to lack of demand). Based on this appearance, researchers confused the species to be of the Leptoseris genus. Through further inspection and with the help of an electron microscope, Tullia Terraneo and Francesca Benzoni discovered otherwise, and gifted the new species its nomenclature. I’d really love to come across one. Pachyseris tend to be one of those innocuous corals that don’t often strike people due to lack of movement and color, but if you know what you’re looking at you can truly appreciate it. Read more about the misidentified discovery over at Nature Middle East, where they also get into some interesting new finds about the percentage of endemic species found in the Red Sea.

Neptune Systems WAV Offers “Extreme” Flow and Controllability

3be0Neptune Systems WAV Neptune Systems WAV Offers “Extreme” Flow and ControllabilityNeptune Systems has been feverishly adding new accessories to their Apex controller over the last couple of years, and they’ve finally debuted their very own water pump. Called the WAV, this new system offers extreme water flow and it comes with a mountain of features and interesting selling points that could give some of the long established pumps a good run for their money. The pump is smaller than numerous other powerheads on the market, yet it cranks out over 3200 gallons per hour, all of which is under full Apex control. But we will hit more on that below. Like most pumps, the WAV attaches the wall of the aquarium via strong magnets, though these are are capable of handling tanks with glass or acrylic up to 3/4″ thick. The magnet mount also allows the WAV to vertically pivot +/- 20 degrees and rotate a full 360, letting the flow hit specific areas within the tank.In terms of controlability, the pump is built and designed to be used seamlessly with the Apex controller, and Neptune Systems even gave the WAV its own module, called the 1LINK. There are numerous flow settings through the controller, and the flow rates can be monitored through the Apex Fusion dashboard just like you would water temperature or pH. All in all, there are 8 pre-built flow programs (Constant, Mavericks, Lagoon, Pulse, Huntington, Rincon, Trestles, and Doheny), and users can program the pump to operate under any one of these modes at any time of the day. In addition to controlling the pumps, users will also be able to monitor each and every one that is plugged into the system. MORE: Neptune Systems WAV Offers “Extreme” Flow and ControllabilityMore:

Our Hobby is Under Attack

pijac1 1 Our Hobby is Under AttackWe’re currently facing legislation that could put an end to our hobby as we know it. And no, I’m not sensationalizing the situation. Please don’t make the mistake of thinking you and your home aquarium(s) wouldn’t be affected, because they absolutely could. We first heard about the potential issues at MACNA 2013, and this past MACNA further solidified the urgency of action to protect our hobby. The current issues date back to a 2009 petition by the Center for Biological Diversity (CBD) to move 83 reef-building coral species under the protection of the Endangered Species Act (ESA). Just last month, the National Marine Fisheries Service (NMFS) listed 20 of those species (5 Caribbean, 15 Indo-Pacific) as threatened. This happened after scientific information submitted by the Pet Industry Joint Advisory Council (PIJAC)—they’re on our side—proved that many of the 83 species did not warrant protection under the ESA. According to PIJAC, the NMFS will likely apply ESA’s “take” prohibitions to the newly listed coral species sooner rather than later. More: Our Hobby is Under AttackMore:
