A Fishy Biology Lesson From Paul

pipefish biology 300x169 A Fishy Biology Lesson From PaulThough fish are our distant cousins, there are more differences than similarities between us. In today’s post, I’d like to explore the various characteristics that make a fish a fish—or not. Skeletal distinctions Of course, not all fish are the same and the oldest fish are not truly fish. True fish have bones somewhat like us, but not exactly. All of our bones are connected together by cartilage, but in fish, the fins are not connected to anything but muscle. The tail is connected to the spine, but none of the other fins are. Sharks and rays have no bones, only cartilage. Built-in buoyancy compensators The swim bladder in most fish (but not all) allows them to maintain neutral buoyancy, or the ability to stay in one place in the water without sinking.

EcoSmart Live App Gets Full Fledged VorTech Control

4814EcoSmart Live App with VorTech Control EcoSmart Live App Gets Full Fledged VorTech Control As part of the continued effort to integrate the VorTech pumps into EcoTech Marine’s EcoSmart Live system, an update to the EcoSmart Live app has been released that allows users to control their VorTech pumps via any iOS powered device. Just last month, EcoTech added VorTech control to their Reeflink, for the first time allowing the ReefLink and EcoSmart platforms to live up to their promises of simultaneous wireless control of the Radion XR30w LED fixtures and the popular pumps. The update app has the same look and feel of the previous verions that only offered Radion control, but adds the touch sensitive wheel right alongside the Radion controls. This touch sensitive wheel is dual purpose, allowing the speed of the pump to be adjusted, as well as the flow mode. This app is free to download from Apple’s App Store and an Android friendly version will shortly follow. MORE: EcoSmart Live App Gets Full Fledged VorTech ControlMore:

Dozens of Huge Tridacnid Clams Seized from Vietnamese Fishermen

aecbSeized Clams from Mengalum Island Dozens of Huge Tridacnid Clams Seized from Vietnamese Fishermen Here is a very troubling story out of Malaysia. According to The Star Online, a group of nine Vietnamese fishermen were arrested for illegally harvesting dozens of giant clams whose combined weight totalled nearly 20 metric tons (almost 44,000 pounds). The arrest is reportedly the first of its kind, but officials strongly believe that this isn’t the first incident for these fisherman, who were arrsted on Monday. The clams have a value of RM500,000, which roughly translates to somethine like $150,000 US, as their shells are valuable in the curio trade as well as in the cosmetics industry. The giant clams, which are probably of the species but could include several others, are obviously endangered and protected marine species that require specialized permitting to collect. It is even illegal to sell the clam shells without special permits. In addition to the fishermen, the boat company is also under investigation, as it is believed that they entered into a joint venture with the fishermen to harvest the clams MORE: Dozens of Huge Tridacnid Clams Seized from Vietnamese FishermenMore:

A Rise in Acidification Means a Rise in Confidence for Scientists and Fish Alike

As ocean acidification increases so does the science behind it. Researchers from the Australian Institute of Marine Science (AIMS) are studying the effects of CO2 emissions near the Milne Bay reef in Papua New Guniea, to better understand how a lowered PH effects reef inhabitants. “We have found that ocean acidification will select large boulder-like coral over structurally complex branching (leaf-like) corals, which are the home of many species like crabs, shrimps and sea stars. As a result, OA has a domino effect: as the habitat structure decreases, the animals that live and hide in their nook sand crannies find it far harder to survive, simply because they cannot hide from predators,” explained Dr Kathrina Fabricius. When the PH is lowered in reef waters calcifying and reef building corals are robbed of their ability to provide structural integrity, and places of cover for other reef inhabitants. As a result inhabitants have to adapt to these changes, which means they will be venturing out further than usual from the reef to find new forms of cover and sustenance.140413135907 large A Rise in Acidification Means a Rise in Confidence for Scientists and Fish Alike Citing numerous findings researcher Alistair Cheal had this to add: “What we have now also found in our study of fish behavior in this environment is that the fish become bolder and they venture further away from safe shelter, making them more vulnerable to predators.” AIMS has been on-site studying this reef for five years as this is the only known location of a CO2 seep near a coral reef. The unique environmental circumstances in Milne Bay will continue to be studied as the site provides a foreshadowed look into the feature of ocean acidification. Read more here.… More:

Giesemann Packs Robust Control Features Into New Matrix-II DIMTEC T5HO Fixtures

c296Matrix II DIMTEC Giesemann Packs Robust Control Features Into New Matrix II DIMTEC T5HO Fixtures Giesemann is one of the few companies out there that isn’t abandoning the tried and true T5HO technology, and in fact, they are still making groundbreaking strides that keep it totally relevant in a time dominated by LED light fixtures. Around a year ago, Giesemann revamped the look of their Matrixx T5HO fixtures to bring their aesthetics in line with their gorgeous Teszla and Futura LED products, and just a week ago they announced even more upgrades. The brand new Matrixx-II DIMTEC will share the same sleek look as its predecessor, but will also incorporate full Bluetooth connectivity that allows it to communicate with a variety of devices including personal computer, Macs, and Android powered devices. The user interface is provided by Giesemann’s own software package, which is very similar to the one used on the Futura LED system. The key selling features of the software include: Point to point multi-plot light cycle programming allowing smooth transitional lighting phases across an available 920 set points. Fully independent channel control over 2 – 4 channels dependent on light unit connected. Transitional color shift dependent on the mix of tubes across each channel. Fully adjustable cloud and weather simulations Fully adjustable lunar phases.

Gems From Down Under

la sn 1024x680 Gems From Down Under
Australia is famous for more than kangaroos and awesome beaches.  Some of the most beautiful corals in the world also live there.  This unique Acropora originated from the Great Barrier Reef however the specimen has been grown to maturity in a captive aquarium in the U.S.  This was accomplished from a tiny seed fragment of the original colony that was imported.  The colony arrived in very rough condition with tissue necrosis advancing and my hopes for survival were slim.  I managed to fragment several small tips before the colony was lost and one half inch seed managed to survive.  Over a two year period the small fragment began to acclimate to the artificial reef it was placed into and grow rapidly.  The new colony began to show some amazing pigments as it matured and the pay off for the effort was realized.  Looking back at the original colony that was imported in my memory, and comparing it to the new captive grown coral, gives me a great sense of accomplishment.  Although corals come from all over the world to our aquariums, some of the most unique and colorful specimens come from down under.… More:
