Connectivity Between Coastal Habitats Of Two Oceanic Caribbean Islands As Inferred From Ontogenetic Shifts By Coral Reef Fishes, I. Nagelkerken, G. Van Der Velde

Gulf and Caribbean Research

Mangroves and seagrass beds are considered important nursery habitats for juveniles of coral reef fishes. Studies have mostly focused on the fish community of just one habitat, so the connectivity between different coastal habitats is often unclear. In this study, density and size of reef fish were determined using a single sampling technique in four non-estuarine bay habitats and four reef zones in Curaçao and Bonaire (Netherlands Antilles). The data indicate that of the complete reef fish community at least 21 species show ontogenetic crossshelf shifts in habitat utilization. The 21 species mainly utilized shallow-water habitats (mangroves, seagrass beds, channel …
