Geometry Type: null

Description: Heatmap of King George whiting – Sillaginodes punctatus juvenile density per hectare per year in Port Phillip mapped over the extent of seagrass (red displays high values >30,000 grading to blue low values <1,000 . To determine spatial variation in King George whiting density, we utilised an existing long-term dataset, collected by the Victorian Fisheries Authority, of density of juvenile King George whiting in seagrass beds around Port Phillip. Fish densities from seagrass beds were combined with novel machine learning methods to predict fish densities across the whole of Port Phillip. Fish densities were then combined with modelling to estimate the biomass of these fish once they become adults.
