Abstract
Routine disease testing of yabbies (Cherax albidus) in Western Australia for over 10 years revealed only few diseases of significance to freshwater crayfish aquaculture. The most serious of these are the recent discoveries of an introduced microsporidian Thelohania sp. and a previously undescribed virus that has been associated with mortalities in yabby dams but has a widespread distribution with low prevalence (<5%). Other parasites and ectocommensals have been recorded from C. albidus in Western Australia including temnocephalans, cilliates, Psorospermium sp. and the nematode Gammarinema sp. However, these appear to have little effect upon the host other than lowering their market value. Testing for crayfish plague (Aphanomyces astaci) since 1989 has shown that this disease is not present in Western Australia. Although many farmers feed lupin seeds (Lupinus angustifolius) to crayfish in Western Australia, this practice can result in mortalities due to enterotoxaemia.
