The Florida Wildlife Commission (FWC) has produced several underwater recordings of native Florida fish species. Scientist studies the biological functions of animal sounds in research called bioacoustics. This method of studying fish is a noninvasive technique giving the researcher insight into fish behavior with no harm to the fish or disrupting their daily activities. FWC has made several recordings available through flickr.

Gary Stokes posted a video of 1,000s of shark fins laid out on a sidewalk in Hong Kong. Shark fin soup is a delicacy in many Asian countries. The method of chopping off the shark fin then dumping it over board and left to drawn is gut wrenching. This video helps put this practice into perspective. I’ve been reading article after article on the banning of harvesting shark fins for soup, but never really knew how large of a problem it is. This video clearly shows that something has to shut this industry down and quickly.

I’ve read that shark fins sell for as much as £380 a pound, which equates to $600 US dollars per pond.

The caption is difficult for me to follow. The video seems to be a sea krait trying to eat an eel. The sea krait is an amphibious snake which is a member of the subfamily Laticaudinae. These snakes are viviparous, meaning they return to land to lay their eggs, unlike true sea snakes. This species is venomous, scientist say their venom is ten times more deadly than a rattlesnake. Note the paddle-shaped tail which makes it a great swimmer.

GHL now offers a flow sensor designed for the ProfiLux aquarium controller. With this additional sensor ProfiLux can display the measured flow of your aquarium pump. If the flow of your pump falls below a given rate the controller will warn aquarist with an acoustic signal, send a SMS message to your phone or an email. The ProfiLux can even switch the failing pump off in extreme cases.

Two different sensors are available:

Flow 100 – 2000 l/h, nominal width DN10, 2x G1/2″ outside thread
Flow 300 – 5000 l/h, nominal width DN20, 2x G1″ outside thread

The ground was broken last Friday for the new Patricia and Phillip Frost Museum of Science. Construction of the new museum is expected to cost $275 million and be completed in 2015. The 250,000 square foot, eco friendly green building was designed by Grimshaw Architects base out of London & New York. Along with a staggering 600,000 gallon aquarium the museum will house a dome 3-D planetarium. Make sure to watch the fly through rendering. More information on the museum can be found on the Huffington Post.

Biologists have been plagued with the question, “Fish evolved in the oceans, but fresh waters have more species. Why?” It has been documented that our oceans today contain only 15-20% of the fish species despite the fact that it is believed that all fish evolved from the oceans making their way to the freshwater bodies. Well, John J. Wiens of Brook University is the Associate Professor in the Department of Ecology and Evolution address this question. Dr. Wiens published his findings in the February edition of Proceedings of the Royal Society. For a briefer understanding of this question review the interview with Dr. Wiens conducted by Benjamin Dual on behalf of EarthSky.

A new species of shark was recently documented by John McCosker an aquatic biologist with the California Academy of Sciences. The Bythaelurugs giddgsi is a member of the catshark tribe. These sharks are found all around the world typically they are bottom dwellers. The sharks were discovered and samples were collected back in 1998 in the area of the Galapagos Island. McCosker and his colleagues reported on the new species in the latest issue of Zootaxa.

This story is becoming more and more common. A private home gets red flagged based on high energy usage and the cops send in the swat team. Mike Baynes of Surrey, British Columbia has an average power bill of about $450, mostly due to his hobby of breeding tropical fish. Luckily for Mike, it wasn’t the SWAT team busting down the door, it was an electrical and fire inspector escorted by the Royal Canadian Mounted Police. As with most of these stories no grow house was found. It appears the government was unhappy with their misguided search so they are making Mike pay for the unsolicited electrical inspection and perform upgrades to his aquariums to the tune of $800.

The Miami Marlins new park has an interesting addition not seen in any baseball parks to date. A large aquarium sits between home plate and fans. I can see the gears turning, you read it right. A saltwater aquarium with coral decorations and live fish is in place behind home plate. Not much information has been made available about the aquarium as far as dimensions or how many gallons of water it holds. What we do know is it is constructed of fiberglass with additional clear acrylic panels that are one inch thick and is said to be unbreakable (or so they hope). First baseman Gaby Sanchez wanted to put the tank to a test. He slung a baseball as hard as he could and the tank still stands. Let’s see how the tank holds up from a stray pitch from Marlins’ star pitcher Josh Johnson.
