Abstract

The introduction of Australian Cherax quadricarinatus into Malaysia as an aquaculture species has resulted in wild populations in several Malaysian states, and it is now considered an invasive species. The introduction coincidentally co-introduced Diceratocephalid, flatworms that externally inhabit C. quadricarinatus. Thirty-three wild C. quadricarinatus were caught alive in Tasik Ayer Keroh, Melaka; while 32 cultured C. quadricarinatus were bought in Bandar Tenggara, Johor. Two species of ecto-symbiont (Diceratocephala boschmai and Decadidymus sp.) were morphologically identified and genetically 18S rDNA sequenced. Currently, only one 18S rDNA sequence is available for Decadidymus sp. in the GenBank, isolated from redclaw crayfish, C. quadricarinatus in Australia. This D. boschmai 18S rDNA phylogenetic analysis was consistent with the data from previous studies.
