Population structure and movement of Octopus maorum and Octopus pallidus, and predation on rock lobster

Samples of Octopus maorum and O. pallidus have been collected from the Eaglehawk fishery and as bycatch from southern rock lobster fishery to determine population structure and spatial and temporal trends. Tag recapture study of O. maorum and O. pallidus in Taroona reserve using PIT tags and movement study using acoustic tracking at Taroona reserve and Eaglehawk neck examine the temporal and spatial scales of movement and habitat use. Octopus tracked using VR2's (presence/absence data) and VRAP (triangulated positional data) at both sites.
