PG - 350-6 LID - S1984-29612015000300350 [pii] LID - 10.1590/S1984-29612015062 [doi] AB - This study evaluated the correlation of hematological parameters with the mean abundance of the monogenean helminth Rhabdosynochus rhabdosynochus in Centropomus undecimalis reared at different temperatures and salinities. The experimental conditions were: 28 degrees C/0 ppt (parts per thousand); 28 degrees C/15 ppt; 28 degrees C/32 ppt; 25 degrees C/0 ppt; 25 degrees C/15 ppt; and 25 degrees C/32 ppt. The prevalence was 100.0% in fish at 28 degrees C/15 ppt, 28 degrees C/32 ppt and 25 degrees C/15 ppt, which was significantly different (p < 0.05) from those at 25 degrees C/32 ppt. The red blood cell (RBC) count, hematocrit and total leukocyte (WBC) count were significantly higher in fish at 28 degrees C/15 ppt and 28 degrees C/32 ppt. The mean abundance of R. rhabdosynochus, hematocrit and RBC showed positive correlations (P < 0.05) with temperature (rho= 0.3908; rho= 0.4771 and rho = 0.2812). Mean abundance showed negative correlations with hemoglobin (rho= -0.3567) and mean corpuscular hemoglobin concentration (MCHC) (rho = -0.2684). No correlation between abundance and salinity was detected among the experimental conditions (rho = -0.0204). The low numbers of monogeneans recorded (min -1 and max -33) explain the few changes to fish health. This suggests that these experimental conditions may be recommended for development of rearing of C. undecimalis in Brazil, without any influence or economic losses from R. rhabdosynochus.
