Recruitment of fishes on coral reefs: a biogeographic comparison

Project Member(s): Booth, D.

Start year: 2002

Summary: Settlement (arrival by larvae in adult habitat) may largely determine subsequent recruitment and population size in marine fishes, but little is known of events at settlement, and how these vary over large scales. We will investigate the interaction of settler physiological condition with post-settlement predation and resident aggression in affecting early survival and growth of coral reef fishes on the Great Barrier Reef and in the Atlantic/Caribbean. This will be the first inter-regional study of recruitment processes in coral reef fishes and outcomes will include improved prediction of reef fish population dynamics and insights into coral reef management and conservation.
