Predator Management

Predatory birds can consume enormous quantities of prawns and juvenile Cobia and can cause significant economic loss to the Australian aquaculture industry.  In order to manage this Pacific Reef Fisheries have implemented an exclusion system to protect our fish from these predatory birds.  For early juveniles from 10g to 200g the fish are reared in cages covered by bird netting within the ponds.  Once they reach 200g the fish are released into a netted section of the pond still with bird netting above.  Once the fish reach 3kg they are large enough that bird predation is no longer a problem and are free ranged across the whole pond.

Nevertheless, there may still been occasions whereby birds find their way past nets or inadvertently get caught within the system.  For any such interaction the details are recorded and are made publicly available in the table below.
