Abstract:
The current paper aims to outline what could be the most common bacterial agents that can have a pathogenic effect on
farm cyprinids form the Prut river basin in order to reduce fish health risks and even prevent future disease outbreaks that are
bacterial in nature. Two field works expeditions to Rompescaris farm -Podu-Iloaiei from Iasi county and to Dracșani fish
farm from Piscicola-Botoșani county were undertaken in May 2021 in order to collect biological samples. The
following fish species were harvested: carp (Cyprinus carpio), silver carp (Hypophthalmichthys molitrix) and mirror
carp (Cyprinus carpio var. specularis) using net fishing and the only the specimens with visible lesions or the moribund
ones were collected. The fish that were apparently healthy were released and the ones that were harvested underwent a
clinical, parasitological and bacteriological investigation.
