Abstract

OBJECTIVE: To report the occurrence of Myxobolus episquamalis in sea mullet, Mugil cephalus L, caught in estuaries in eastern and western Australia. DESIGN: A prospective study of commercial catches of mullet in the Clarence River of NSW and individual cases from other areas. RESULTS: The organism caused pale, white to pink, raised lesions on the scales and fins of sea mullet. Occurrence of infection was highest in spring and in a marine (down-river) environment compared to a brackish environment. Up to 6% of fish were affected in commercial catches. CONCLUSION: The infection is widespread in Australian mullet, but rarely causes significant economic loss.
