  1. Habitat Mapping Mark Meekan (AIMS) Cary McLean (AIMS) David Williams (NRETA) Jewfish Workshop 2006

  2. AUSTRALIAN INSTITUTE OF MARINE SCIENCE Aim Provide a description of aggregation sites in terms of bathymetry and current flow

  3. AUSTRALIAN INSTITUTE OF MARINE SCIENCE Map of sample sites Caution Point Darwin Chambers Bay Channel Point

  4. Put the listening station results into a spatial context Are fish occupying a particular habitat type? How do movement patterns relate to current flows? AUSTRALIAN INSTITUTE OF MARINE SCIENCE Objectives

  5. Used an Acoustic Doppler Current Profiler Profiled a series of transects across the study sites over flood and ebb tides Caution Point Chambers Bay Peron Islands AUSTRALIAN INSTITUTE OF MARINE SCIENCE

  11. AUSTRALIAN INSTITUTE OF MARINE SCIENCE Work in Progress • Develop model of current flow • Add listening stations • Look at spatial patterns of sonar signals (fish distributions) in relation to current flow • Catching a bigger jewfish than Chris Errity
