Florida Scientists Prompt Spawning of Atlantic Coral in Artificial Setting for First Time

Scientists in Florida have artificially produced reproductive spawning of an endangered Atlantic coral species for the first time in an aquarium environment, a breakthrough they say holds great commitment in efforts to revive collapsed reefs in the wild.

The achievement, declared this week at the Florida Aquarium in Apollo Beach close to Tampa, borrowed from lab techniques induced at the London-based Horniman Museum and Gardens and used previously to begin spawning of 18 species of Pacific coral, delegates said.

Scientists plan to use their newly-acquired expertise to produce new coral colonies that can in the future repopulate the beleaguered Florida bank system, one of the largest on the planet and one killed by climate change, pollution and disease in recent years.

The newly grown corals ought to make for even stronger populations than existing colonies since each individual shall be bred with “new genetics and new traits that may be more immune to what will happening on our reefs sooner or later,” she mentioned.

Prompting corals to release their sperm and eggs in aquarium tanks involves controlling their synthetic settings to imitate their natural ocean home throughout a yearlong reproduction cycle.

That means carefully regulating water temperature modifications from summertime to winter, and using special lighting to mimic sunrise, sunset, and even lunar cycles that serve as organic cues for the coral in preparing to spawn.

Collaboration between the Florida and London centers on the program started in 2017 as the scenario facing Florida’s reefs grew more terrible because of the spread of a new coral disease called Stony Coral Tissue Loss.

The 180 units collected by the Florida Aquarium were amassed under license from the Florida Keys National Marine Sanctuary and Nova Southeastern University. Thirty of those had been used in the spawning aquarium, O’Neil stated.
