Abstract

Although recruitment is often influenced by microhabitat characteristics that affect larval settlement and post-settlement growth and survival, the influence of some habitat features, such as the presence of conspecifics and the accessibility of food, are poorly understood, particularly on temperate reefs. We investigated the ecological determinants of recruitment in the southern hulafish (Trachinops caudimaculatus; McCoy, 1890), a small zooplanktivorous reef fish in Port Phillip Bay, Australia. We hypothesised that T. caudimaculatus would show positive relationships with microhabitat characteristics that provide greater access to food and shelter for newly settled recruits. To test this hyp..
