As with the shallow broken rock habitats, blennioid density in macroalgal forests also fluctuated through time.
- No acute macroalgal clearance effects were observed on blennioid composition or abundance.
This study investigated how spatial and temporal scales influenced the stability of a guild of blennioid fishes.
In both the fish removal and macroalgal clearance experiments, blennioid composition in 4-[m.sup.2] quadrats was overrepresented by Ruanoho whero and Forsterygion varium.
Within 100 m of mid-Waterfall reef to seaward in deeper water, and 50 m landward to shallower water, an additional seven blennioid species were common, yet even within the largest fish removals in mid-Waterfall Reef these seven species did not become established.
