Following more than a decade of protection from fishing activity, the direct and indirect\udeffects of fishing on benthic community structure are becoming apparent inside no-take marine\udprotected areas (MPAs) on Tasmania’s east coast. Gradual increases in the abundance and average\udsize of putative abalone predators inside the no-take Maria Island Marine Reserve (MIMR) have\udcoincided with increases in the minimum size of the emergent abalone Haliotis rubra. This suggests\udthat the threat of predation may influence the structuring of abalone populations. The abundance of\udemergent abalone was negatively associated with predator abundance, especially the rock lobster\udJasus edwardsii, inside the MPA and in adjacent fished areas. Abalone leave cryptic habitat at\udsmaller sizes in fished areas compared to abalone inside the MPA. Although the patterns in abalone\udsize at emergence (SAE) were strongly correlated with rock lobster abundance and average size, the\udabundance of other predators (demersal predatory fish and crabs) or competitors (sea urchins) did not\udinfluence the patterns in abalone SAE. However, predation mortality in isolation could not account\udfor the differences we observed in abalone size frequency distributions between MPA and adjacent\udfished locations. We suggest that a combination of factors including predation, intra and interspecific\udcompetitive interactions are responsible for patterns in abalone SAE
