โœฆ Synopsis

The diurnal use of space by 25 resident species of coral reef fishes was investigated along three depth (10 to 40 m) transects over an 18 month period. Emphasis was placed on the small, cryptic members of the communities. Three aspects of the use of space --temporal utilization, occupancy and time span --are defined and quantified for each of the species. In addition, an estimate of the diurnal home range volume of each species is provided. The territorial pomacentrids showed the highest level of temporal utilization, holding the same territories throughout the study. The consistent presence of the holocentrid species within the reef infrastructure had the potential to influence the space available to other species. Some species residing in tube-worm holes and sponges also exhibited constant use of space.
