Boat Noise a Culprit for Decline of Sea Hare

Scientists from the Universities of Bristol and Exeter and the École Pratique des Hautes Études (EPHE) CRIOBE in France have long understood that artificial marine noise can affect the ecology of marine life, but they now understand that propeller noise from boats can also affect change in the life cycle of one of the most important reef inhabitants. Lead author Sophie Nedelec, a PhD researcher at the University of Bristol and EPHE had this to offer: “Traffic noise is now one of the most widespread global pollutants. If the reproductive output of vulnerable species is reduced, we could be changing communities and losing vital ecological functions. This species is particularly important because it eats a toxic alga that affects recruitment of fish to coral reefs.”

Researchers found that when exposed to anthropogenic noises throughout gestation, some of the Stylocheilus striates eggs studied for this experiment were found to be underdeveloped and in some cases actually perished as a result. Co-author, Dr Steve Simpson, a marine biologist and senior lecturer at the University of Exeter, said: “Boat noise may cause stress or physically disrupt cells during development, affecting chances of survival. Since one in five people in the world rely on marine animals as a major source of protein, regulating traffic noise in important fisheries areas could help marine communities and the people that depend on them.” Read more here.

Red Tide Killing Marine Line Off Florida Coast

 The Gulf of Mexico, specifically the West Coast of Florida, is currently experiencing a red tide bloom that has killed tens of thousands of fish.  Red tide is a phenomena that is caused by high concentrations of toxic dinoflagellates. The Red Tide has also killed a number of manatees and is threatening Florida’s end of summer, normally booming, tourism. While Red Tide is not uncommon to Florida in the summer, the concentration of dinoflagellates in this concentration that is currently approaching, is higher than has been since in Florida 2005. Living on the East Coast of Florida, I am in the Ocean at least twice a week. However this summer I have had to skip some outings due to red tide and flesh eating bacteria. Its not a good summer for us Floridians. MORE

Old School

PL2014 1024x680 Old School
Old school captive grown corals have a certain appeal.  The fact that they are recognizable by the trained eye and hold their pigments throughout the years can surely add to their allure.  A small pigment of a certain seed fragment can be passed on to the full grown colony and yet the beauty remains constant.  Unlike some of the newer captive grown corals or wild specimens which can change dramatically through the years, the old school varieties are proven and well known to the trained eye.  This specimen is commonly called the Pink Lemonade and has been in the hobby for many years.  It is one of a handlful of yellow Acropora specimens that have paid off the few people who invested a great amount of time in their care.  Given patience and excellent water quality a mature colony can be achieved in a relatively short time compared to some slower growing stoney corals.  One of the many advantages of old school Acroporas.

Clearing the Air on Ozone: Part 1

ozone1 1 Clearing the Air on Ozone: Part 1The use of ozone in home aquaria is far from a new idea. In fact, 20+ years ago, ozone was commonly used by both public aquaria and hobbyists alike. I experimented with the use of ozone on my classroom system a little over a decade ago. However, the system I invested in was of very poor quality. We had two probes fail in less than a year, and the monitor indicated that our generator had also failed to continue to generate the gas. Needless to say, I dropped out of ozone, having experienced mixed results at best. Fast forward to three years ago More: Clearing the Air on Ozone: Part 1

Blue Tang Aggregation, Acanthurus coeruleus

6bf1Blue Tangs 457x303 Blue Tang Aggregation, Acanthurus coeruleusHi friends, Here’s a colorful photo of a big school of Blue Tangs cruising through the reef with a single goatfish (yellow fish) trying hard to blend in. I really had quite a laugh underwater watching this single goatfish, it’s like he always wanted to be a blue tang and figured they wouldn’t even notice if he hung out with them. We see these large groups called “aggregations” on the reef here every single day and I still never seem to get tired of it, they are just so beautiful. Adult blue tangs have three social modes: territorial, wandering, and schooling. Territorial adults defend their home rage from other members of the species MORE

Commence Drooling Over This Amazing Favia

1e70Exclusive Corals Ultra Favia Commence Drooling Over This Amazing Favia
Setting faces to stunned! We always love sharing hot new corals, and this one is absolutely unbelievable. Arguably one of the best releases of the year, this unnamed favia comes to us via Exclusive Corals, an online retailer who recently shared the image on their Reef2Reef page. The coral sports a deep red hue, reminiscent of the war corals that found intense popularity in years past, and it is accented with the yellow, purple and neon green colors make up the coral’s “eyes”. While the details of this coral have yet to be finalized (e.g. name and price), two decent sized frags have been cut for a future availability. They both appear to have five or more mouths, which is nice considering how fragging usually goes in this hobby these days. If you’re as in love with this piece as we are, be sure to snatch up one of the limited release frags in a hurry, because we all know they won’t last long. And for the record, we’d be tickled to death if this coral went without a designer name and designer price tag. We understand corals of this caliber command a high price, but we’d love to see a shift in the status quo of coral naming back to a more old school approach…that being no fancy names for colorful corals MORE: Commence Drooling Over This Amazing Favia
