  • Data are means ± s.e.m. (N=9 fish per treatment). Hb, haemoglobin; Hct, haematocrit; RBC count, red blood cell count; MEV, mean erythrocyte volume; MEH, mean erythrocyte haemoglobin content. Other details and statistics as in Fig. 1. No treatment-related effects were observed in HCT, RBC or MEV. Values for initial fish were (mean± s.e.m., N=9): Hb, 7.8±1.0; Hct, 35.3±2.3; RBC count, 1.40±0.18; MEV, 255±30; MEH, 55.9±8.0.

    Different letters indicate statistically different values within columns (Student's t-test, P<0.05).
