Common carp is a traditional freshwater fish species and has been culturing in several aquaculture systems in Northern Vietnam. This species was commonly infected with variety of parasites, the low efficacy of common drugs and chemical treatment is one of major barrier for enhance the Common carp production. This study was conducted to examine the safety and treatment efficacy of Dermo-gard, which contained 56.9% of Ethylenediamine Dihydroiodide, on parasites infected common carp, including Metacecaria of Centrocestus formosanus, Myxobolus sp. (internal prasite), Dactylogyrus sp. and Lernaea cyprinacea (external prasites) by immersion and oral methods. The results showed that Dermo-gard at dose of 0.2g /L for 2-4 hours by immersion and at dose of 0.2-0.4 g/kg of feed for 7 days by oral are safe for fry and fingerling common carp. The immersion at dose of 0.2g /L for 2-4 hours was effectively treated Trichodina and Dactylogyrus but could not treated larvae of C. formosanus; Myxobolus and Lernear. While oral treatment by apply feed based drug of Demo-gard at dose of 0.2-0.4 g/kg of feed for 7 days could treated successfully all above prasites. The result indicated that application of feed based Demo-gard could be used to control both external and internal parasites infecting Common carp.
