Assessment of health risks to southern bluefin tuna under current culture conditions

A qualitative fish health risk assessment based on a single risk evaluation matrix was provided for the tuna aquaculture in Australia. The overall disease risk ranged from negligible to low. Blood fluke, gill fluke and hypoxia recorded greatest risks. There is a general lack of knowledge about tuna health. The risk assessment process should be considered dynamic, and reviewed on a regular basis as more comprehensive information becomes available.
