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:

6 Ways to Prevent Photoshock in Aquarium Corals

photoshock coral 300x169 6 Ways to Prevent Photoshock in Aquarium CoralsMany of the corals and other sessile invertebrates we keep in reef aquariums are considered “photosynthetic,” meaning much of their nutrition is produced by photosynthetic algae (zooxanthellae) residing in their tissues. Thus, there is a direct link between the type and intensity of a reef aquarium’s lighting and the health—or even survival—of the corals and other invertebrates it contains. However, it’s very important to understand that corals acclimated to a certain level of lighting can be severely stressed if they’re suddenly exposed to higher-intensity lighting. This commonly happens when: A specimen kept under subpar (no pun intended) lighting during shipping or in a dealer’s tank is newly introduced to a brightly lit aquarium. The reef system’s lighting has just been upgraded, for example from fluorescents to metal halides or LEDs. The hobbyist waits too long to replace aging bulbs or tubes. Dissolved organic compounds that cause yellowing of the water are suddenly removed (e.g., via chemical filtration with activated carbon). So how can you avoid photoshocking your invertebrates? Here are six ways: 1) Research your inverts’ lighting requirements Photosynthetic invertebrates vary widely with respect to their lighting needs More: 6 Ways to Prevent Photoshock in Aquarium CoralsMore:

Attention: European Aquarists

Aquarium tank public domain 300x185 Attention: European AquaristsEurogroup for Animals (based in Brussels) is asking MEPs, ahead of the May elections, to sign a pledge to work towards banning the import of wild caught animals OATA (The Ornamental Aquatic Trade Association) Chief Executive Keith Davenport sees it as the hobby being under threat: “Taken to its logical conclusion this would mean if you want to keep tropical marine or freshwater fish, corals, soft corals or other invertebrates you might as well forget it. All of these are either wild-caught and/or exotic, which means they’re not native to the UK, so they would no longer be available to buy.” OATA is urging keen fish keepers to contact MEPs to urge them not to sign the Eurogroup for Animals pledge.  A special #handsoffmyhobby campaign has been launched to get passionate aquarium hobbyists to shout about what they love about keeping fish. We’re all for keeping the hobby going, but at what cost? Is this pledge not a step in the right direction?  Should exotics be included in the pledge?  Should they not rather say that all exotics should be captive bred?  Why not tell them what you think.  Have a look at: http://www.ornamentalfish.org for more.… More:

Heliofungia Propagation

Heliofungia 300x168 Heliofungia PropagationAlthough notoriously intolerant of tissue damage, the beautiful Heliofungia actiniformis is an exciting addition to any reef display. Willing to test this coral’s vitality, I made an attempt to propagate one. 1. The Heliofungia was forced to retract by hand. This reduces contact between the propagating tool and the coral’s sensitive tissue, minimizing damage and stress on the coral. Retracted 300x168 Heliofungia Propagation2. To reduce the amount of heat transferred to the polyp, the Heliofungia was cut in half using a diamond band saw. This saw uses a drip mechanism to keep the subject cool. The cut was made perpendicular to its mouth, which enables the mouth to recover more rapidly, allowing the coral to feed.… More:

Copper Treatment For Marine Ich

PowderBlueTangwithIch zps81993234 Copper Treatment For Marine IchCopper treatment is a very effective way to rid and prevent Marine Ich. In a Fish Only system you can dose the display tank with it, but do not expect to ever keep a snail, shrimp, coral, anemone, or anything else BUT fish. This is one good reason a quarantine tank is a must for anyone who wants to have corals and it is not hard at all. Cupramine Copper Treatment WHAT YOU NEED -10-30 gallon aquarium – Heater and Thermometer – Filtration (without carbon) – Copper test kit and Preferred Treatment – Refractometer – Water quality test kits – RO water and salt mix – Plastic or PVC Decor for fish to hide – (Optional) Food container of sand for fish that bury themselves – A light to observe and give the fish a proper day/night schedule example quarantine or hospital tank image via AdvancedAquarist.com PREPPING THE QUARANTINE 1. Take any sponges incorporated with your planned filtration and place them in a clean part of your sump. This will build beneficial bacteria while reducing the gunk buildup so you can use your quarantine tank within a couple weeks rather than making it go through a cycle for longer on its own. 2. Fill the tank with saltwater and allow it to get to temperature. 3. Install the cycled sponges from your sump into their locations on your QT filtration More: Copper Treatment For Marine IchMore:

Branching Anemone, Lebrunia danae, Cnidarians

a16dBranching Anemone 457x305 Branching Anemone, Lebrunia danae, CnidariansGood morning from Curacao. If there is a downside to living in the Caribbean other than not being able to find the goods and services one is used to in the States, it’s not having seasons! Honestly, it does not feel like it’s Christmas! Today is hot, the wind is gently blowing, iguana’s and birds are everywhere, the flowers are blooming, here a bikini, there a bikini and the sound of music is on the horizon from countless resorts along the beach! And yes, I know most of you would trade your snow and cold weather for a Christmas here but really the holiday season is just not the same without a little of the cold stuff. We are going over to Stijn’s grandparents Christmas eve for a big dinner and Christmas morning after a little present opening we will head out for an island adventure with the dogs. MORE: MOREMore:

Don’t Contaminate Your Saltwater Aquarium!

washing hands 300x169 Don’t Contaminate Your Saltwater Aquarium!Washing your hands is an easy way to help prevent contaminating an aquarium.When we think about toxins in a marine aquarium, the first thing that usually comes to mind is ammonia or a toxic allelopathic chemical released by a coral—in other words, a biologically produced toxin originating in the tank itself. But sometimes hobbyists are unwitting sources of harmful compounds or pathogens from outside the aquarium. As one might well imagine, accidental contamination of an aquarium can potentially harm or even kill valued specimens. The trouble is, there’s no practical way for hobbyists to test for most contaminants, so it’s often impossible to determine the cause of the “anomalous” illness or losses in such instances. The old proverb “An ounce of prevention is worth a pound of cure” definitely applies here, so let’s look at some of the preventive measures you can take to keep your saltwater system free of external contaminants: Avoid toxic handiwork Hobbyists’ hands are probably the most common mode for transferring contaminants into aquariums. After applying lotion, handling garden chemicals, pumping gas, waxing your car, cleaning the tub, polishing the silverware, or otherwise contaminating your hands, it’s all to easy to completely forget and then absentmindedly reach right into your aquarium to rearrange or retrieve something. It’s wise to develop the habit of washing your hands (taking care to rinse the soap off thoroughly, of course) before reaching into the tank for any reason. If necessary, post a small reminder note on or near the tank that reads, “Have you washed your hands?” Ideally, you should avoid putting your hands in the tank unless it’s absolutely necessary anyway (whenever possible, use aquarium-safe tongs for righting or removing objects from the tank). If you must use your hands, it’s a good idea to wear protective gloves. Keep the spray at bay Cleaning sprays, cooking sprays, pesticides, room deodorizers, and other finely aerosolized products/chemicals can drift over your aquarium and then settle onto the water More: Don’t Contaminate Your Saltwater Aquarium!More:

Salt Smart Tips for Soothing Those Hair Algae Headaches

While some livestock will eat green hair algae (GHA), it’s best to find the cause rather than chase the problem.Of all the irksome algae that can take hold in a saltwater aquarium, hair algae probably causes hobbyists more consternation than any other. So named for its hair-like, furry, or feathery appearance, this filamentous algae (for the sake of simplicity, I’ll use “algae” for both the singular and plural forms of the noun) is primarily an aesthetic issue in fish-only aquariums, but in reef systems, it can quickly overgrow and smother corals, turning a once thriving system into a tangled, unsightly mess. Like most troublesome algae, hair algae thrives in systems with elevated levels of dissolved nutrients—i.e., nitrate and phosphate (think: fertilizer). In intensely illuminated reef systems with excess dissolved nutrients, the proliferation of hair algae can be positively explosive! However, even reasonably well maintained systems that aren’t powerfully lighted can see their share of this nuisance algae if the balance tips even slightly in favor of its growth. So, what should you do if hair algae rears its ugly, scruffy head in your system? Prepare to be patient! As the old saying goes, only bad things happen quickly in marine aquariums. While it’s wise to take prompt action against hair algae when it manifests itself, don’t expect to eradicate it overnight. Also, don’t assume a single action or technique will get rid of this gunk More: Salt Smart Tips for Soothing Those Hair Algae HeadachesMore:
