Summary: Settlement and early establishment (recruitment) are major determinants of population viability of marine fishes. Early survival through the settlement gauntlet can be affected by fish condition and body size, interacting with biotic (e.g., competitors, predators) and physical (e.g., habitat) factors. Here, the mechanisms for this link will be investigated, including effects of condition and body size on survival, food competition, and growth. A series of innovative laboratory and field experiments will assess the relative importance and synergism of these mechanisms, and lead to a model of reef fish establishment that will assist in sustainable management of fisheries resources on coral reefs and similar marine habitats.

Keywords: fish settlement, physiological condition, predation risk, food competition,
