Culture systems influence the physiological performance of the soft coral Sarcophyton glaucum.

ABSTRACT: There is an urgent need to develop means of ex situ biobanking and biopreserving corals and other marine organisms whose habitats have been compromised by climate change and other anthropogenic stressors. To optimize laboratory growth of soft corals in a way that could also benefit industry (e.g., aquarium trade), three culture systems were tested herein with Sarcophyton glaucum: (1) a recirculating aquaculture system (RAS) without exogenous biological input (RAS-B), (2) a RAS with "live" rocks and an exogenous food supply (RAS+B), and (3) a simple flow-through system (FTS) featuring partially filtered natural seawater. In each system, the effects of two levels of photosynthetically active radiation (100 or 200 μmol quanta m^-2 s^-1) and flow velocity (5 or 15 cm s
