Need

Rock Flathead supports commercial mesh-net fisheries in Corner Inlet; however, CPUE for this fishery has shown a declining trend since 2005, while remaining above the management reference point. The stock structure of rock Ffathead in Victorian waters is largely unknown, presenting uncertainty for fishers and managers when assessing the future of the fishery and ensuring the sustainability of the stock.

Objectives

1. Determine the population structure of rock flathead in south-eastern Australia, with emphasis on understanding how the Corner Inlet population relates to other populations

2. Quantify the movement and residency patterns of rock flathead in Corner Inlet
