Understanding links between river flows & prawns in the Gulf

11 April 2019

Gulf rivers and productivity links

New research has investigated the potential effects of river flow regulation on catches of the commercially important banana prawn (Penaeus merguiensis).

Bayesian models predict that peak monthly flow volumes < 2,500,000 ML will result in low probabilities of high prawn abundance offshore. This is the first time that thresholds have been identified and the modelling suggests there is probably little capacity to regulate or modify the freshwater flow without reducing prawn catches.
