Title:

Patterns of interaction between habitat and oceanographic variables affecting the connectivity and productivity of invertebrate fisheries

Project Number:

2015-025

Organisation:

Deakin University Geelong Waterfront Campus

Principal Investigator:

Daniel Ierodiaconou

Project Status:

Current

FRDC Expenditure:

$270,000.00

Program(s):

Communities, Environment, Industry

Objectives

1. Integrate commercial catch and survey data with LiDAR-derived seafloor structure information to identify the spatial structure and patch-level productivity of reef systems,potential abalone fishable habitat extent and map important source reefs of abalone larvae.

2. Development of a high resolution hydrodynamic model for Victorian coastal waters that allows the modeling of larval dispersal between individual reef complexes throughout state waters.

3. Development of a biophysical larval dispersal model to map the probable dispersal pathways for H. rubra and SRL across Victorian reef complexes.

4. Determine if recruitment across the respective fisheries is influenced by adaptive genetic factors.
