Full description
The fish fauna of the edge of coral reefs in Torres Strait was investigated by underwater visual transects at 276 sites on 41 reefs between August 1995 and January 1996. The fish community contained most common families of tropical Indo-Pacific coral reefs.Acanthurids, Chaetodontids, Pomacentrids and Labrids were the most widespread and speciose families observed. The relative abundance of each species at each site was used to classify sites with multi-dimensional scaling (MDS). The species composition varied strongly across the region with sites classifying into four distinct groups. These represented groups of fish species most abundant on (1) the eastern outer ribbon reefs; (2) the mid- shelf reefs; (3) central Warrior reef complex and (4) the western reefs north of Moa Island.
These patterns in fish community structure were related to changes in the relative proportions of the major benthic habitats in each area. Many species tended to be abundant either in areas of high coral cover (eastern outer ribbon reefs) or high algal cover (central and western reefs). Other factors that were correlated with fish species composition included the distance from sources of terrestrial runoff in Papua New Guinea and Cape York, northern Australia. This effect is likely to be indirect, through the influence of runoff of benthic habitats. These results show that fish communities in Torres Strait are strongly structured and influenced by the benthic habitats. The distribution of benthic habitats are in turn heavily influenced by the regional physical processes that occur because of the location of Torres Strait between Australia and Papua New Guinea.
