en Effects of Propolis on microbiologic and biochemical parameters of Rainbow trout (Oncorhynchus mykiss) after exposure to the pesticide fish disease fish disease پژوهشي Orginal research papers Cypermethrin is a potential toxic pollutant that directly threatens the aquatic ecosystems and environment. Propolis, a natural product collected from plants by honey bees has many functions, such as antimicrobial, antioxidant, and anti-inflammatory. This study attempted to detrmine some biochemical and microbiological parameters of rainbow trout fillets after <a name="OLE_LINK113"></a><a name="OLE_LINK112">exposure to </a>propolis and cypermethrin. The results of the current study revealed that levels of malondialdehyde (MDA), lactic acid, total volatile base-nitrogen (TVB-N), total counts of psychrophilic, and mesophilic bacteria increased in cypermethrin groups (P<0.05), compared to control group. Furthermore, there were no significant differences in pH levels between groups. Additionally, levels of MDA, lactic acid, TVB-N, count of psychrophilic, and mesophilic bacteria in cypermethrin+propolis treated groups were significantly reduce in comparison to exposed groups with cypermethrin (P<0.05). The findings also showed that the fillet quality some biochemical and microbiologic functions of fishes could be changed in groups that exposed to cypermethrin by propolis. <o:p /> Biochemical parameter, Cypermethrin, Microbiological parameter, Propolis, Oncorhynchus mykiss 490 503 http://jifro.ir/browse.php?a_code=A-10-1-173&slc_lang=en&sid=1 M.
