摘要：This study has resulted in the collection of biological, population and habitat data that improves
our understanding of the role of western rock lobster in the deepwater ecosystem. The relationship
between western rock lobster size and abundance and habitat established in this study is important
for the effective management of the fishery in an ecosystem based fisheries management (EBFM)
framework. For fisheries managers this information has application in two main areas. Firstly,
it enables the examination of the spatial distribution of lobster abundance and size by habitat
type and in combination with fine resolution fishing effort data may allow the assessment of
standing biomass and harvest rate. Secondly, it provides invaluable information for the design
and implementation of marine protected areas as a tool for research and species conservation.
For researchers this study provides an assessment of different techniques to assess the benthic
habitat of deepwater ecosystems that has previously been a costly exercise requiring specialised
equipment. For industry this information is the first step in the process of assessing the impact
of lobster biomass removal in the deepwater and provides detailed information for the ecological
risk assessment (ERA) process required to meet Department of Environment, Water, Heritage and
the Arts (DEWHA) regulations and maintain marine stewardship certification (MSC).
