In recent years, new genotypes within the yellow head complex of viruses have been discovered in farmed prawns both within Australia and overseas. This report describes research undertaken at the CSIRO Australian Centre for Disease Preparedness Fish Diseases Laboratory (ACDP AFDL), Geelong, Victoria...
The 2012 Tasmanian biotoxin event represents a paradigm shift for seafood risk management in Tasmania and Australia as a whole. The causative dinoflagellates are extremely difficult to identify by routine plankton monitoring, and are toxic at very low cell concentrations (50-100 cells/L). Sampling...
In this project, we reviewed the scientific literature and collaborated with Australian abalone growers to develop a case definition for summer mortality. The case definition developed for summer mortality is as follows:
i. Chronic mortality of unknown cause (if in doubt take this to mean...
Over the last 4 years, scientists from the Centre for Aquatic Pollution Identification and Management (CAPIM) have been leading a research program to better understand the risks to seafood safety during toxic cyanobacterial blooms in the Gippsland Lakes and best practices for monitoring...
This project is a collaboration between the Department of Agriculture and Fisheries (DAF) and the Cobia aquaculture sector, predominantly Pacific Reef Fisheries (PRF). It was undertaken to consolidate the aquaculture in Australia of Cobia, a species offering considerable potential as a...

The accumulation of paralytic shellfish toxins (PST) of microalgal origin in abalone tissues causes a trade and human health risk that requires active management. Toxic algal blooms of the genus Alexandrium have recently caused several abalone harvest closures on the east coast of Australia. Risk...
The use patterns of pesticides in Australia has changed over the last decade, with the use of pyrethroid and neonicotinoid insecticides increasing. The limited water quality data that is available has measured increased concentrations of the neonicotinoid insecticide imidacloprid in...
Amoebic gill disease (AGD) continues to have a significant economic impact upon production of sea-farmed Atlantic salmon in Tasmania. Reducing mortality is economically important for the fish farmer and is equally important from an animal welfare perspective. The process of freshwater bathing...
