Blood analysis is important in fish health investigation and may be influenced by intrinsic and extrinsic factors. However difficulties exist in the use of blood analysis in the investigation of fish health due to the paucity of species specific, gender and age based reliable references. The current study therefore aims to determine some blood parameters in order to provide reliable references for dry season of the normal condition values of C. gariepinus, a widely cultured fish in Nigeria. This study involved random sampling of 900 C. gariepinus aged 4, 5 and 6 months from earthen pond for three years. Data obtained for blood parameters using standard method were analyzed using descriptive statistic, students'-test, one-way ANOVA level of significant set at p ~,0.05. Results showed the female had significantly (p ~,0.001) higher values than the males for each age bracket and the values increased sig nificantly (p 0~,.05) with increased in PCV. hemoglobin, RBC, WBC, total protein, potassium, sodium, Creatinine, ALT, AST and glucose. The females and males values at 4, 5 and 6 months old were PCV (32.14 ~c 0.19% vs 26.72 ~c 1.l2; 36.45 ~c 1.39% vs 32.33 ~c 1.46%; 40.83 ~c 0. 73% vs 35.01 ~c 0.08%.), total protein (3.98 ~c 0.16g/l vs 3.49 ~c 0.18g/l; 4.45 ~c 0.10g/l vs 4.33 ~c 0.04g/l). Lymphocytes, neutrophils, mono cytes and ESR values showed no stable trend in gender differences with increased age. In both the females and the males, lymphocytes decreased significantly (p ~,0.05) while neutrophils and monocytes increased significantly (p~,0.05) with increased age. ESR decreased significantly (P~, 0.05) in the males and non-significantly in the females with increase in age. It is hoped that these values obtained would serve as a reliable reference to enhance an appropriate intervention in the culture of C. gariepinus aged 4. 5 and 6 months in earthen pond which may be extrapolated for use in other culture systems.
