Estimating larval retention at individual reefs by local scale three-dimensional flows is a concern for managers trying to understand and predict larval dispersal. This study models variation in larval retention times for a range of reef shapes and circulation regimes, using a reef-scale three-dimensional hydrodynamic model. It also explores how well larval retention time can be estimated from flow speed around the reef, reef dimension, and vertical diffusion. The mean residence times found in the study (0.48–5.64 days) indicate substantial potential for self-recruitment of species whose larvae are passive, or weak swimmers, for the first several days after release. These findings suggest that good estimates of larval retention may be obtained from relatively coarse-scale characteristics of the flow, and basic features of reef geomorphology.
