Large, mostly male, fish (>30 cm fork length) predominated on the open coast and in deeper water (>10 m), while smaller fish predominated in the more protected estuarine areas and in the subtidal regions ( 70% of the adults by intense spear fishing. Experimental sites were recolonised by >20 cm males and females, and rarely by juveniles. There was no significant difference between the pre- and post-removal estimates of home range of tagged fish at removal sites or in controls.
