The Use of Larvae Or Recruits in Coral Restoration Initiatives: Symbiodinium Acquisition Does Not Differ Between Coral Life Stages In the Wild

Abstract: Active restoration initiatives are increasingly considered in natural resource management. Laboratory reared coral larvae and recruits have been proposed for stock production but it is unknown if their use impacts subsequent symbiosis once transplanted to the reef. We exposed laboratory and field settled aposymbiotic recruits (recently settled < 1 month) to Symbiodinium in the wild, then analysed the acquired communities using ITS-2 sequencing. There was no significant difference between treatments based on overall community and diversity metrics, or differential abundance of individual taxa. These results suggest that early acquisition is analogous and thus supports the use of either life-stage as an option for reef restoration.
