Abstract This study was conducted to assess the effect of water quality of the Ogun River on the haematological indices of the African catfish Clarias gariepinus. Samples of water and Clarias gariepinus were collected from Ogun River (Station I, Opeji and Station II, Lafenwa) to determine and compare effects of possible differences in water quality on haematological parameters of Clarias gariepinus. The results demonstrate that higher index values were recorded at station II than Station I for almost all the physicochemical parameters and only sulphate values from Stations I and II were statistically significant (P < 0.05).

Global technological advancement has resulted in the gradual replacement of traditional bulk size compounds with nano-sized ones with diverse useful characteristics. This study is focused on the toxicological assessment of three nano-metallic oxides (SiO2, Al2O3 and CuO) in comparison with their equivalent bulk sizes using African Catfish (Clarias gariepinus). The study involved sub-lethal exposures to binary mixtures of selected ratios (1:1; 2:1 and 1:2) of the respective metallic bulk and nano oxides as well as their triple mixture (1:1:1) for 28 days. The catfishes after 28 days were subsequently subjected to haematological tests (Haemoglobin, Packed Cell Volume, Red blood cells, Platelets, Neutrophils, Lymphocytes, Mean cellular volume, Mean Cell haemoglobin, and Mean Cell haemoglobin Concentration). The results of the haematological assessment indicated that most of the nano-sized oxides showed no significant difference (P>0.05) compared to control whereas the bulk sizes either showed no difference or decrease in the count compared to control. In most of the binary mixtures, catfishes exposed to bulk sizes had lower levels of the haematological parameters but there was no overall trend. The introduction of nanoscale metallic oxides into production activities should be with caution since they may have a similar mode of toxicity to the existing bulk sizes.

A feeding trial was carried out for 56 days to ascertain the effects of Telfairia occidentalis (fluted pumpkin) as a feed additive on the haematological profile and nutrients value of Clarias gariepinus carcass. C. gariepinus fingerlings (mean body weight 9.6g) were randomly distributed in plastic bowls at nine fish per bowl in triplicates. Five diets designated as D1 to D5 with 40% crude protein containing 0, 50, 100, 150, and 200g/kg of T. occidentalis leaf powder were fed to C. gariepinus fingerlings at 5% body weight per day. The results showed that T. occidentalis additive significantly (P≤0.05) improved the haematological parameters of the fish. The mean value of white blood cells (WBC) count (μL) in the diets fed with T. occidentalis were significantly higher (D2-D5 : 870.20, 864.80, 840.30, 876.40, respectively) than the diet without T. occidentalis (D1 783.15). A similar trend was observed in PCV, MCV, MCHC, MCH, and platelets. However, HB D1 (control) had higher values than the diet containing T. occidentalis. Meanwhile, in carcass quality, there was an increase in the crude protein of all the fish but the group that consumed T. occidentalis had a higher carcass crude protein and lower lipid, while the control had a higher lipid value. Meanwhile, the initial values obtained before the feeding trials had lower crude protein and higher lipid value when compared with the fish that was fed with the experimental diet. In conclusion, T. occidentalis leaf meal can be utilized to improve the haematological  parameters of the fish, with an increase in the WBC there is a high possibility of the fish to withstand pathogenic attacks because Blood is a major parameter that determines the physiological, immune , and nutritional status of an organism, also WBC are important blood  constituents for defense against diseases, pathogens and unwanted foreign bodies in an organism.

The study was designed to investigate the sub-lethal effects of paraquat on haematological parameters and histopathology of the gills, skin and liver of Clarias gariepinus juveniles of mean weight (38.26±1.20g) and length (17.50±1.55cm). The fish were exposed to 10, 20, 30, 40 and 50% of the 96hrsLC50 value of 107mg/l estimated from the 96 hours acute toxicity test. Blood samples were collected into heparinized tubes for the analyses of some haematological parameters, while the gills, skin and liver were also removed for histological examinations following standard procedures. The result revealed a significant reduction (P < 0.05) in the values of red blood cells (RBCs), haemoglobin (Hgb), packed cell volume (PCV) and erythrocytes indices from the control. The white blood cells (WBCs) and platelets (Plt) were however increasing significantly (P < 0.05) from those of the control as the test concentrations increased. The histology of the gills revealed some alterations such as epithelial proliferation, vacuolation of the mucus, hyperplasia of epithelial tissue of the gill filament, lifting and necrosis of the secondary lamellae. The exposed skin showed mucous cell proliferation, erosion of the epithelial lining, hypertrophy, necrosis of epithelial cells and widening of the epidermal and dermal layers. The liver exhibited cellular proliferation, sinusoid enlargement, congestion of the central vein, paranchymatous degeneration, vacuolar degeneration, pyknotic nucleic degeneration, legions and necrosis with severity as concentration of paraquat increases. The gills and skin were observed to be the most affected tissues in this study. The study also revealed that paraquat was toxic to C. gariepinus and causes some haematological and histopathological alterations in the fish blood and tissues at concentrations higher than 30mg/l. Therefore, the use of paraquat by farmers should be regulated particularly in area close to the aquatic environment.

Background: The toxic effect of Nittol detergent on the haematological parameters of the African catfish (C. gariepinus) sub-adult was investigated. The experiment was conducted in triplicates forthe four treatments. Behavioral changes in fish exposed to different concentrations of Nittol detergent ranged from erratic swimming, moribund movement, jumping and lack of balance. Similar changes were not observed in the control throughout the experiment. Nittol detergent is composed of linear alkyl benzene sulphonate (LABS), sodium tripolyphosphate (STPP), sodium carbonate, sodium sulphate, sodium per-borate and sodium silicate (perfume) as active ingredients. The fish were exposed to concentrations 1.0 g/L, 2.0 g/L, 3.0 g/L and 4.0g/L. At 1.0 g/l concentration, the mean mortality was 80% with an initial erratic swimming. Results: It was observed that mean mortality increased drastically with increasing Nittol Detergent  concentrations. At a concentration 3.0 g/L, total mortality was observed within 72 hours of exposure preceding moribund swimming while total mortality was observed at 4.0 g/L. The concentration at which 50% of the experimental fishes were killed (LC50) was 0.9 g/L. Results from statistical analysis indicated that mortality varied significantly with concentrations as higher values recorded higher mortality rates. However, mean values showed the highest mortality (74%) with Nittol detergent. Haematological results obtained from blood profile analysis showed various degrees of alterations and changes in values when compared to the control. The PCV of the exposed fish was 26% when compared to 27% in the control, HB was 8.9 (GDL) as against 9.0 Gdl of the control, total WBC was 640 x 109/L as against 1280 x 109/L of the control. The RBC reading was 4.7 compared to 5.3 (mm3) of the control. For the differential counts, the lymphocyte was 80%. Neutrophils were 4 % and monocyte 16% compared to 62%, 8% and 30% of the control respectively. The results revealed a significant decrease in PCV counts for 8.0, 16.0, 25.0, and 50.0ml/l concentration when compared to the control. There revealed significant decrease of haemoglobin count for 8.0 ml/l group (p>0.05) and significant decrease for 16.0 ml/l, 25.0 ml/l and 50.0 ml/l groups (p<0.05), when compared to the control. The results showed insignificant decrease of RBC count for 1.0 g/l (p>0.05) and a significant decrease for the 2.0, 3.0 and 4.0 g/l groups (p<0.05), compared to the control. This means that as the toxicant concentration increased, the fish red blood count decreased the more. This further implies that at higher concentration of, RBC reduces correspondingly. Lymphocytes, monocytes, and neutrophils in the control set showed (apparently normal cell after) hematoxylin and eosin staining. Differential blood samples exposed to various concentrations of Nittol Detergent showed denatured cells, haemolysis and blood cell shrinkage. Conclusion: It was therefore concluded that Nittol Detergent has significant toxic effect on the haematological parameters of C. gariepinus and recommended the control disposal of this detergent into aquatic bodies to reduce the negative impact on the blood quality of aquatic organisms.
