Drones Used to Combat Illegal Fishing in Belize

On the forefront of technological reef research the country of Belize has assigned drones to combat illegal fishing throughout marine protected areas, in what may be the first use of drones for conservation. “Belize has been a leader in the establishment of marine protected areas, including the world-famous Glover’s Reef Marine Reserve, but fishing regulations are difficult to enforce on the open sea,” said Julio Maaz, Communities Fisheries Coordinator for WCS’s Marine Program in Belize. “Drones offer a means of improving the rate of detection of illegal activities at a fraction of the cost required for patrol vessels.” 140722152432 large Drones Used to Combat Illegal Fishing in Belize The unmanned aerial drones will begin a new monitoring program that is a partnership between the Wildlife Conservation Society who provided the technical expertise, and the Belize Fisheries Department. “This exciting new enforcement tool will help the government and local communities protect their most valuable assets — the fisheries and coral reefs of Belize’s coastal waters,” said Dr. Caleb McClennen, Executive Director of WCS Marine Conservation. “The world’s oceans are in dire need of low cost innovations for improving the cost efficiency and effectiveness of enforcement efforts. This represents an exciting pilot program for Belize, the wider Caribbean, and nearshore marine parks and fisheries around the world.” Read more here!More:

Terrible Advice Tuesdays (T.A.Tues): The Easy Way To Get Rid of Mushroom Corals

Terrible Advice Tuesdays (T.A.Tues): Eradicating mushroom corals requires simply cutting the top of the coral off. With the top removed, the base will die. The rest of the story: Whoever said that must have fantastic luck or be completely delusional. The only way I’ve ever successfully eradicated mushroom corals from a tank is by cutting the top off, then completely covering the base with epoxy. If the smallest amount of the base is left uncovered, it will regrow a new top and the coral will start growing again. I’ll also add enough epoxy such that I cover an extra inch (1″) of the rock around the base of the coral to make sure it doesn’t somehow find light and start growing again. Other mushroom eradication methods I’ve tried include MORE: Terrible Advice Tuesdays (T.A.Tues): The Easy Way To Get Rid of Mushroom CoralsMore:

Some Corals Can ‘Tough It Out’ In Acidic Oceans

Lagoonal patch reef 300x225 Some Corals Can ‘Tough It Out’ In Acidic Oceans A set of experiments undertaken in Hawaii, Moorea and Okinawa, and now documented in the journal Proceedings of the Royal Society B, offer a glimmer of hope for the future of coral reefs under the continuing threat of Ocean Acidification. In the study, two coral taxa (Pocillopora damicornis and Porites) and two calcified algae (Porolithon onkodes and Halimeda macroloba) were subjected to conditions that mimic oceans if CO2 concentrations in the atmosphere reached 1000 ppm, more than double the levels today. Surprisingly, three out of the four could still easily form their hard calcium shells even in such an acid ocean. Although positive, the discovery doesn’t necessarily mean that ocean acidification won’t be bad for corals and algae though. It does mean that across the Pacific some of species may prove to be more resilient than others. More: Some Corals Can ‘Tough It Out’ In Acidic OceansMore:

Blue-Light Diving, Blue-Light Underwater Photos

cc32Coral 1 Day 457x305 Blue Light Diving, Blue Light Underwater PhotosGood morning from Curacao! Once again we got a little rain this morning which as many of you now know, that’s a big deal! Our little island was severely suffering from a 6 month drought but is now slowly starting to green up again and we love it!! So yesterday I ended up doing three dives again, one before 9:30am, one at noon and one starting at 8:00 last night. I had spent much of the afternoon preparing for my night dive which involves setting up the camera with blue-filters over the strobes and a yellow filter over the lens to capture fluorescence on the reef at night. This new kind of night diving is called “blue-light diving” and it’s a total blast! MOREMore:

Review: TMC GroBeam 1500 Ultima ND

IMG 6676 300x200 Review: TMC GroBeam 1500 Ultima NDAs LED aquarium lighting continues to evolve rapidly, let’s take a look at how this technology can benefit our reef tanks beyond the illumination of corals and fishes in our main display tank. As well as providing such lighting, LED units can also be extremely useful for fueling algae filters in sumps, indeed we’ve shown this before with our review of the Arcadia EcoAqua 30watt spotlight. With many hobbyists now switching to LED for this purpose, in this review we look at another unit that can be adapted from its primary use as a freshwater planted tank light, and put to good use in a marine setting. Obtaining our unit in good order from renowned online operation Swell UK, out-of-the-box our GroBeam tile feels solid and well-made. This 2013-made 1500 ND (Natural Daylight) model is the latest ‘version’ of the tile boasting higher output LEDs than the preceeding ‘1000’ model. An inspection of the contents and instructions confirms that this is a product from a specialist manufacturer, purposefully-designed and optimised for the task in hand. With a colour temperature of 6500k, this unit is well-suited to illuminating a range of marine macro algae… Chaetomorpha and Caulerpa. The LED tile is fitted with 10 Cree More: Review: TMC GroBeam 1500 Ultima NDMore:

WWC Bounce Mushroom Looks Like a Tiny Volcano Gushing Lava

0b48WWC Bounce Mushroom Coral WWC Bounce Mushroom Looks Like a Tiny Volcano Gushing Lava
The popularity of mushroom corals is on the rise, and thanks to corals like this, we can certainly see why. There has been an influx of rather brightly colored, fluffy looking mushrooms into the hobby over the last couple of years or so, and hobbyists are falling all over themselves to get them, often paying a premium for the best and brightest of the bunch (no real surprise there). At MACNA last year in Miami, we happened across some of these very shrooms, which had retail prices soaring well over $1000 a pop. Always on the cutting edge of the coral trends, Jason Fox shared these images of his Bounce Mushroom Coral over on Reef2Reef, which was sourced from World Wide Corals…hence the WWC portion of the coral’s name. WWC was the group who had these on display at MACNA 2013, but this particular coral is a standout from those that we came across at the show and even the ones we continue to see online. According to Jason’s post, this frag is the biggest he’s ever sold, tipping the scales at 2″x2″ with huge, orange “plumage”. The price is set at $1450 shipped.
