Abstract

The effects of predation by fishes, in relation to habitat complexity and periodicity of sampling, on abundances of fishes and macroinvertebrates were investigated using controlled caging experiments during summer 1999/2000 at multiple locations (Blairgowrie, Grand Scenic, and Kilgour) in Port Phillip Bay, Australia. A second experiment evaluated biological and physical cage effects. Sites and habitats, but not caging treatments, could generally be differentiated by the assemblage structure of fishes. Regardless of species, small fishes were generally more abundant in seagrass than unvegetated sand, although the nature of this pattern was site- and time-specific. Depending on the site, abund..
