CORAL Excerpt – Project Coral: Inducing Predictable Broadcast Spawning of Stony Corals In Captivity

Project Coral – By Jamie Craggs | Coral Magazine, March/April 2014 The following excerpt is a selection from “Project Coral” by Jamie Craggs. Get it now in the March/April 2014 issue of CORAL Magazine Whilst there have been captive coral spawning events in a few public aquariums and a small number of home aquariums around the world, they have always been unplanned, incidental events, often catching the onlooker by surprise. So the challenge of spawning corals in a controlled, predictable way is considerable and presents some major obstacles. Despite this, I’ve always felt it could be achieved if the approach was right. When we attempt to breed aquarium animals, the method is the same in principle. First we need to research the individual environmental and/or nutritional components that trigger a species to reproduce in the wild; then, using that knowledge, we replicate these conditions in our aquariums. Surely, inducing broadcast corals like Acropora to spawn in captivity should be no different, even if their environmental cues and triggers are more elusive to define

Feeding Corals with Sustainable Aquatics Hatchery Diet

Scolymia eating Hatchery Diet pelletsIf you are unfamiliar with the Tidal Gardens coral farm, much of our aquaculture process depends on the fast growth of our corals and the long-term health of our colonies. Coral nutrition is a major factor. We constantly experiment with different foods for our coral. Corals that are fed consistently have dramatically improved coloration and display much better polyp extension. It’s always interesting to see coral colonies that we have had for years sitting next to colonies we recently acquired. They look like completely different animals in many cases. As much as we like to stuff our corals with food, some corals are not as receptive to feeding as others.

Todd Gardner Named 2013 Aquarist of the Year!

26438 100306616679542 7024784 n Todd Gardner Named 2013 Aquarist of the Year!
Saturday night Todd Gardner was named the 2013 MASNA Aquarist of the Year. This announcement was no surprise to many of us aware of Todd’s accomplishments. I have had the great honor of experiencing first hand the late nights and hard work that has gone into achieving many of those successes. I have lived through the excitement and seen the disappointments that inevitably precede those achievements. While there are many who may not know much about Todd besides his recent successes with Liopropoma sp., he has over 20 years in the industry and a list of accomplishments that is impressive even for someone with that longevity.… More:

Milletseed Butterflyfish update

Working with Milletseed Butterfly’s (Chaetodon miliaris) has presented some unique challenges. After experiencing some issues during shipping and quarantine, we made some changes, and have a batch of 23 healthy, vibrant fish from Disney’s Rainbow reef, in Hawaii. The fish are eating very well and spawned twice during quarantine. However, due to the chemicals in the water during quarantine, the eggs were not viable. This gives us hope that we will soon have viable eggs to start working with since the fish are out of quarantine and the water free from chemicals. Eggs are approximately 710 microns in diameter, with a central oil globule. Fertilized eggs will float on the waters surface and are skimmed off the surface with egg collectors in the tank. Non viable eggs of milletseed butterfly's collected in the quarantine tank.We canulated the broodstock in an effort to determine what sex ratio and stage of maturity was present in our population. The results were quite shocking. Out of 19 fish that were cannulated only 1 was male. Shouldn’t he be in heaven! Having already spawned we do not think that this will be a major issue, however it may limit fecundity of the group. Our goal is to gather several more males and introduce them to the population.
