Abstract

In this study we analyzed the effects of NaOCl solution on the blood and biochemical parameters of the rainbow trout Oncorhynchus mykiss (Walbaum, 1792). The treatment lasted for three days with prior dechlorination of the water. Significant differences in the concentration of K+, Ca2+, Cl-, proteins, glucose were detected and the largest variations were found for creatinine concentration (P<0.05). Significant differences were found Hct, Hb concentration, RBC, WBC, MCH and MCHC values, percentage ratio of lymphocytes, segmented granulocytes and the total number of neutrophil granulocytes (P<0.05). Small doses of NaOCl alter the acid-base balance, suggesting a very low-level adaption in the rainbow trout.
