Effect of potassium ferrate(VI) on survival and reproduction of Ichthyophthirius multifiliis tomonts.

摘要: Ichthyophthirius multifiliis is an important freshwater teleost pathogen that can infect most species of fish worldwide and often leads to significant economic losses the aquaculture industry. Potassium ferrate(VI), as a potential therapeutic agent for external protozoan parasite infections, has been proven kill I. theronts effectively; however, no information available on effects potassium ferrate(VI) exposure tomonts. This study evaluated survival reproduction The results experiment 1 showed at concentrations 2.4, 4.8, 9.6, 19.2 mg/L resulted in tomont rates 82.2%, 34.2%, 14.6%, 0, respectively, differences were noted between treatments control (P < 0.05). Additionally, this was designed determine effect toxicity age tomont. indicated encysted more resistant treatments. In addition, investigate when collected from infested goldfish solutions different (0, mg/L) 30 min. It found survivals significantly lower than those demonstrated bath with possibly effective method treat ichthyophthiriasis.
