Blue Whale Entangled in Netting off the Coast of Mexico

whaleOn Friday, the U.S. Coast Guard, NOAA (the National Oceanic and Atmospheric Administration), and a whale rescue expert responded to a distressed Blue Whale that was entangled in fishing line and tethered to a red buoy, off the California Coast. The rescue team worked until Friday evening to try and get the Blue Whale free, and then suspended the rescue efforts at nightfall. When the team returned the next morning, the whale was gone. Search efforts went into effect almost immediately. A plane, a helicopter and a boat searched all day Saturday for the Blue Whale, without any success.   MORE

No Aquarist is an Island: 5 Reasons to Attend MACNA 2016

Thousands of salties attended the Saturday night banquet (this shot only shows part of the massive room)! Caribbean Chris and I just got back from MACNA 2015, held last Friday through Sunday in Washington, DC, at the Marriott Wardman Park, and what a weekend it was! From the venue to the speaker lineup to the banquet and everything in between, we think this year’s MACNA (Marine Aquarium Conference of North America) really delivered on every level. Kudos to all who had a hand in coordinating and presenting this massive convention and making it appear so seamless (extra special shout out to WAMAS and MASNA)! MORE

Long Island Collecting Log: Some days, it isn’t about the collecting

 Contrary to commonly-held beliefs, a day in the life of a marine biologist bears little, if any, resemblance to a National Geographic documentary. I remind my marine science students of this at the beginning of each semester. Even if you have the privilege of being paid to do real research on something really awesome, the reality is that most of your time will be spent reading papers, analyzing data, and writing grant proposals.

Review: Ecotech Marine Vectra M1 pump

Vectra-1-502x320It seems like when Ecotech Marine releases a new product, it immediately becomes a hit. The Vortech circulation pumps have become the bar by which all circulation pumps are judged, and Radion lighting is often considered the high standard in LED lighting. So how does Ecotech fare in branching out to a less exciting product, the return pump? It’s not that return pumps aren’t exciting; it’s just that they aren’t really thrilling. They pump water from a sump back into the aquarium, and up until now most of them had a fixed gallon per hour (gph) flow rate. Although it could be argued that return pumps are a very under-rated part of reef aquariums.  MORE

Subtropical Acropora, warmer waters, and ocean acidification.

New, advanced online publication of research by Foster and colleagues in the journal Coral Reefs explores the impacts of ocean acidification and global warming on the development of the tabling coral Acropora spicifera, an iconic species of the subtropical western Australia coast. The workers implemented three experimental treatments: Acidified conditions (pCO2 of 900 μatm, with a water temperature of 24 °C), warmed temperatures (27 °C, pCO2 of 250 μatm, and a combination of warm and acidified waters (27 °C, pCO2 of 900 μatm). Settlement and calcification rates were monitored and compared to control conditions.

Deadly Battle: Sea Snake v. Poison Fish

150901173418-sea-snake-and-stone-fish-1-exlarge-169These are two venomous creatures you generally want to avoid when you see in the ocean: the sea snake and the stone fish.  Sea snakes and stone fish contain venom, and although not likely to bite unless threatened, you generally want to steer clear of these guys. Rick Trippe, a champion spear fisherman in Australia, caught the epic battle between these two venomous creatures on camera. Trippe was on his boat in Darwin coming back from a fishing trip, when he noticed something floating in the water.
