Manta rays next on restaurant menus as shark populations decline

As shark populations around the world decline, conservationist are concerned that Asian chefs may look for Manta and Devil Rays as replacement for the popular shark fin soup. Since rays swim slowly and near the surface, they make for easy targets to the fishermen that hunt them using harpoons. At this point, the number of rays being fished is relatively low, but this could shortly change.

Marine biologist Tim Clark of the University of Hawaii says “Mantas and mobulas are being used as shark fin soup filler” in cheap versions of the popular soup.

Ray are believed to live for over 50 years, and only reach maturity in their teens. Even at that, they only produce 1 pup every 1 to three years. Coupled with how easy they are to hunt, ray are a perfect target for overfishing. In addition to becoming a shark replacement, ray gills are being used in Traditional Chinese Medicine (TCM) to reduce toxins and purify the blood.

As the market for shark fin soups is consistently growing, the shark population is declining; reportedly by 80% over the past 15 years.

250 gallon REEF SYSTEM. Chapter 1

Posted on Wednesday, June 2nd, 2010 at 9:52 am

Here’s a great video of a 250 gallon reef system comprised of a 150 gallon display tank, a 50 gallon refugium, and a 50 gallon sump. This system is the result of an upgraded from a previous 75 gallons reef tank. The 50 gallon refugium is home to a beautiful mantis shrimp. Located at the bottom of a staircase, the beautiful display tank is home to a variety of tangs, wrasses, chromis, clownfish, sps corals, lps corals, zoanthids, mushrooms, and many other interesting little critters. Check out the diamond watchman goby feeding as it siffs through the sand. Several clams are beautiful as well as helpful in improving water quality. Enjoy.

The Swabbie is a motorized protein skimmer neck cleaner from Avast.

Grassy LeDio 27 High Power LED Lamp by Volxjapan

Posted on Tuesday, June 1st, 2010 at 11:10 am

Volxjapan has just released their Grassy LeDio 27 LED spotlight. The Grassy LeDio 27 is currently available in ReefBlue (6 blue, 3 white) and ReefWhite (4 blue, 4 white, 1 amber) models, each featuring 9 x 3W bulbs (hence the 27). Volxjapan decided to use a newly developed 60 degree prism lens which offers great spread and intensity. This LED lamp does not generate substantial heat, and therefore passive cooling is sufficient. The LeDio 27 LED uses a standard E26 screw in socket, so mounting it shouldn’t be a problem. The approximate life of these LED lamps is 50,000 hours.

Posted on Friday, May 28th, 2010 at 12:15 pm

The Blue Glow was at the Midewest Marine Conference 2010 this past week, and we took a close look at their Acrylic Frag Racks.

Since each shelf can be used as a standalone shelf, they can easily be removed fro cleaning. The Blue Glow is happy to customize shelf sizes for any application, and retailers should check these out as they make terrific displays. The “standard” unit is 4 shelves, measures 18″x17″x5.5″, accommodates 338 standard plug, and cost $89. A stackable option is also available for $54.

Aquatic Life at the Midwest Marine Conference 2010

Posted on Friday, May 28th, 2010 at 11:38 am

We spotted Aquatic Life, who’s tag line is “bringing the ocean to you, wherever you may be”, at the Midwest Marine Conference this past weekend. We had a chance to chat with co-owner Michael Elliot, and discuss the overall direction and philosophy of the company. We are very impressed by ingenuity of the Aquatic Life products, and their approach to development and design. Aquatic Life seems to be very focused on improving existing designs/models and providing hobbyists with products that perform well and are easy to use. Keep an eye on the Aquatic Life HID light fixtures, which come with the Aquatic Life HID lamps.

Reef Nutrition at the Midwest Marine Conference 2010

Posted on Thursday, May 27th, 2010 at 2:07 pm

We ran into Randy Reed of Reef Nutrition at the Midewest Marine Conference 2010 this past weekend. Randy had a “full menu” of Reef Nutrition products on display, including their newest one, Oyster Feast. Oyster Feast – Food for Invertebrates, consists of Oyster Eggs and Ovarian Tissue (1-200 microns). It’s naturally size-appropriate for feeding SPS and LPS corals, and is highly suitable for a broad range of other invertebrates. Reef Nutrition reports that Oyster Feast, which is high in protein and Omega-3 fatty acids, stays suspended in the water column while eliciting fast coral feeding response. The ovarian tissue used in Oyster Feast has all the benefits and nutritional value of the eggs, only it is delivered a a smaller particle size, down to 1 micron.
