Аннотация

The effect of Actara insecticide on the common carp (Cyprinus carpio Linnaeus) was studied, and its sublethal concentration (LC50) for this species was estimated. Exposure to Actara at a concentration of 400 mg/L in freshwater was shown to kill all the common carp individuals within 24 h, while 24-h preconditioning at an Actara concentration of 100 mg/L promoted survival of animals when they were subsequently exposed to the insecticide at a concentration of 400 mg/L for 5 days. Estimates of serotonin-modulated anticonsolidation protein (SMAP) in the common carp brain and liver by enzyme-linked immunosorbent assay (ELISA) following exposure to Actara at a concentration of 100 mg/L for 24 h showed its increased level in both organs (p < 0.001), particularly manifest in the liver. It is concluded that preconditioning elevates SMAP tissue levels and promotes thereby protection of the organism against damaging effects of lethal Actara concentrations.
