A breakout of enteritis among yellowtail kingfish is causing financial concerns at Clean Seas Tuna.
The South Australian aquaculture company is reviewing the future of its yellowtail kingfish operations in the Spencer Gulf after 35 percent of juveniles were wiped out by an infection of the intestines.
Tests are continuing to determine the cause of the health problems.
A strategic review of the business will look at the impact of the health problems and other options for its future, Clean Seas said on Wednesday.
