Tagging is an important tool for estimating key fisheries parameters such as fishing mortality, natural mortality and growth. This project identified the need for future tagging projects to undertake preliminary studies to determine the impact of tagging on both growth and survival, and we developed...

Of the nineteen abalone (Haliotidae) species recognised in Australian waters (Geiger 1999), ten are endemic and two dominate the commercial, recreational and illegal harvests in southern States: the blacklip abalone Haliotis rubra Leach and the greenlip abalone H. laevigata Donovan.

Bacterial disease is a major cause of stock loss in aquaculture. The severity of infection may range from acute to chronic through to benign. This latter condition, termed covert infection, is insidious, as fish may appear to be outwardly healthy but during periods of stress, these carriers may...

This report presents findings of a research project which examined the extent to which the stated objectives being pursued to guide the management of Australia’s fisheries are aligned with community expectations for sustainability. And, further to this, the extent to which the design of objectives...

Maugean Skate (Zearaja maugeana) are only known from two isolated estuarine systems located on the west coast of Tasmania, representing one of most restricted distributions of any elasmobranch. There is, however, uncertainty about the continued persistence of the species in one of these estuaries...
