The experiments carried on ponds of CCDP Nucet, researches being axled on comparative and comprehensive analysis of pathologic incidences on common and Japanese carp. This researches present theoretical and empirical convenience, because allow to elaborate of prophylaxis and disease control on. The ichthyo-pathologic exam was carried on for 271 exemplars of common carp, subspecies Cyprinus carpio carpio and 31 exemplars of ornamental carp (koi carp). There were identified 30 species of allogenic parasites, 9 species of parasites characteristic for carp as well as some common species of parasites with broad dissemination on cultured fish. All analyzed exemplars of showed parasitic infestation, but with a different extent of extensively and intensively. The most important epidemiologic factors from the analyzed ponds that increase the parasitic invasions were represented by the presence of infested fish, rearing in policulture of species and ages, as well as by the high density, water quality, thermic and flow fluctuations.
