“…Variations in some of the parameters when compared with other species are in agreement with the reports of Gabriel et al (2004), Hrubec et al (2000), Owolabi (2011) andDe Souza Neves et al (2014) as age, species and different management systems had been reported to affect haematological and blood biochemical values of fishes. The significantly increased (p<0.05) values of most of the parameters assessed in the adults when compared with the young adults could be due to an increased metabolic activity associated with increased growth rate.…”

This study investigated the normal haematological and blood biochemistry profile of apparently healthy cultured hybrid catfish Heteroclarias reared in concrete ponds in South East Nigeria. A total of 20 fish of two age ranges and equal sexes were used, and determination of haematological and blood biochemistry profile followed standard procedures. Results obtained for the parameters assessed for the young adults and adults respectively are summarized as follows (mean±standard error): packed cell volume, 32.50±1.10 and 37.33±0.75 %; haemoglobin concentration, 11.81±0.45 and 13.00±0.21 g/dl; red blood cell count, 3.14±0.07×10 6 and 3.09±0.07×10 6 /μl; mean corpuscular volume, 103.44±3.13 and 122.82±3.97 fl; mean corpuscular haemoglobin, 37.65± 1.50 and 42.35±1.47 pg; mean corpuscular haemoglobin concentration, 37.11±1.12 and 33.97±0.47 g/dl; white blood cell count, 18.39±1.04×10 3 and 20.92±0.67×10 3 /μl; alanine amino transferase, 30.90±0.18 and 38.17±0.16 IU; aspartate amino transferase, 54.20±0.22 and 50.29±0.25 IU; alkaline phosphatase, 5.00±0.54 and 9.55±0.74 IU; total proteins, 2.20±0.07 and 4.05±0.10 g/dl; albumin, 0.96±0.03 and 1.38±0.04 g/dl; globulin, 1.22±0.07 and 2.70±0.10 g/dl; plasma blood glucose, 94.17±8.16 and 175.89±10.38 mg/dl; total cholesterol, 85.33±4.34 and 153.14±8.63 mg/dl; calcium, 4.80±0.48 and 11.64±0.41 mg/dl; blood urea nitrogen, 1.24±0.27 and 1.03±0.13 mg/dl; and body weight, 287.50± 8.18 and 711.11±36.11 g. Results obtained showed significantly higher (p<0.05) values in adults in all the parameters assessed except red blood cell count, mean corpuscular volume, white blood cell count and blood urea nitrogen and significantly lower (p<0.05) aspartate aminotransferase activity. There were no significant changes (p>0.05) due to sex in all the haematological and blood biochemistry parameters assessed. Data generated from this study was considered important as deviations in the normal haematology and blood biochemistry values have a predictive value for general pathological and specific organ changes in the body.

“…The use of leukocyte profiles to assess immune responses is also an important tool for the monitoring of stress in fish (Davis et al ; Souza Neves et al ; Zebral et al ). Fish exposed to intermediate concentrations of ammonia (0.28 mg NH 3 ‐N/L on Day 1) and nitrite (10.43 mg NO 2 ‐N/L on Day 5), and after recovery for those previously exposed to 0.28 and 0.57 mg NH 3 ‐N/L, presented an increased proportion of monocytes and/or granulocytes and a reduced number of lymphocytes.…”

This study investigated the secondary stress responses of Paralichthys orbignyanus exposed to ammonia and nitrite and after recovery. Fish were exposed to 0.12, 0.28, and 0.57 mg NH3‐N/L, or 5.72, 10.43, and 15.27 mg NO2‐N/L for 10 d followed by the same time length for recovery. Ammonia‐ and nitrite‐free water was used as a control treatment. Blood samples were collected after 1, 5, and 10 d of exposure and after recovery. Fish exposed to ammonia presented lower and higher glucose levels after 10 d of exposure and recovery, respectively. Ammonia induced initial and transient ionic disturbances and metabolic alkalosis. Nitrite exposure caused hyperglycemia, increased plasma K+ levels, and respiratory alkalosis, whereas metabolic acidosis was observed after recovery. Increased proportion of monocytes and/or granulocytes and reduced number of lymphocytes were demonstrated in fish exposed to 0.28 mg NH3‐N/L (Day 1) and 10.43 mg NO2‐N/L (Day 5) and after recovery in the 0.28 and 0.57 mg NH3‐N/L treatments. Exposure to ammonia decreased the proportion of granulocytes on Day 5. In conclusion, exposure to concentrations at 0.12 mg NH3‐N/L and 5.72 mg NO2‐N/L provoked physiological disorders in Brazilian flounder. Nonetheless, fish exposed to 5.72 mg NO2‐N/L following a 10‐d recovery period showed complete resumption of homeostasis.

The study sought to assess the haematological and biochemical alteration in Clarias gariepinus as environmental contamination biomarkers in rivers Benue and Donga. water samples were taken for physiochemical examination while fish blood was obtained for haematological and biochemical analysis using a Haemacytometer. When compared to the reference standard there was a substantial (P>0.05) difference in the RBC of the C. gariepinus in both rivers, but no difference in the WBC, HB, PCV, MCV and MCHC. However, there were no statistically significant (P0.05) difference in the ALT, ALP, AST and glucose levels of C. gariepinus in either river. The ALT, ALP and glucose levels of C. gariepinus in both rivers differed from the reference standard. Temperature, pH, dissolved oxygen and nitrate levels were higher in Benue river than in the Donga River, but ammonia levels were higher in the Donga river. As a result of these finding, it is possible that Benue river is more polluted than the Donga river, and the C. gariepinus in Donga river is healthier than those in the Benue river. Hence, adequate water management and pollution control should be implemented to halt the flow of the Benue river.
