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