Pharmaceutical effluents collected from Bompai industrial area, Kano State were assessed for their physiochemical parameters, heavy metals and effect on haematology and biochemical changes in Clarias gariepinus. Laboratory analyses were performed using standard methods in a Completely Randomized Design (CRD). Five test solutions of the effluents (0, 25, 50, 75, and 100% v/v) were prepared for LC50 96hr acute toxicity test. The LC50 for 96hr was 48.7% concentration of effluents by volume. Experimental fish were exposed to sublethal concentrations of 0.00% 2.43% (5/100 LC50), 12.17% (25/100 LC50), 24.35% (50/100 LC50) and 36.52% (75/100 LC50) for 28days.  Physicochemical parameters recorded were higher than WHO recommended Standard with the exception of water temperature. Heavy metals concentrations decreased in the order of Cr > Cu > Pd > Cd. Red blood Cells count, haemoglobin concentrations, packed cell volume, lymphocytes and monocytes of the experimental fish decline significantly (p<0.05) when exposed with 2.43, 12.17, 24.35, 36.52% effluents  compared to the control. White blood cell count, mean corpuscular haemoglobin, mean corpuscular volume, mean corpuscular haemoglobin concentrations, neutrophils and eosinophils were significantly higher (P<0.05) than the control. However, a significant increase (P<0.05) in the activities of serum aspartate aminotransferase (AST), Alkaline Phosphatase (ALP) and alanine aminotransferase (ALT) were recorded as the exposure period continued when compared with control. It is concluded that the effluents induces haematological and biochemical alterations. It is therefore recommended that regulatory bodies should adopt holistic approach on the aquatic pollution abatement, bearing in mind the negative impact to non-target organisms.

A 56 day study was carried out to evaluate effect of temperature changes on survival, growth performance and haematology of Clarias gariepinus fingerlings fed housefly maggot meal (magmeal) diet. Ninety (90) Clarias gariepinus fingerlings, (initial mean weight 4.33±0.03g) were subjected to different environmental regulated temperature conditions in three locations (laboratory, outdoor, greenhouse). The observed average temperature was 26.53±0.01°C, 26.06±0.01°C and 31.52±0.00°C for laboratory, outdoor, greenhouse, respectively. Ten fingerlings stocked per experimental tank were fed in triplicates at 5% body weight in two portions per day. It was observed that different water temperatures affected fish growth. All experimental fish in the greenhouse died after 8 days of exposure. This happened around 14.00 hrs when water temperature reached 40°C. There was no significant difference (P<0.5) in final weight, weight gain, food conversion ratio and standard growth rate among the fish reared in the laboratory (26.53°C) and outside tanks (26.06°C), respectively. The initial carcass crude protein (Cp) value was 58.97%. At the end of the experiment fish reared in the laboratory had a crude protein value of 63.97±0.06% Cp and those reared outdoor (26.06°C) had 71.28±0.00% Cp. No significant difference in values of packed cell volume; white blood cell; haemoglobin and mean corpuscular haemoglobin concentration was found between fish reared in laboratory (26.53°C) and outside (26.06°C). However, the red blood cell (RBC); mean corpuscular haemoglobin and mean corpuscular volume showed significant difference (P>0.05). The result confirms that Clarias gariepinus fingerlings reared at a mean temperature of 26°C (within the recorded optimal temperature range for good growth) performed well. Clarias gariepinus fingerlings are not able to survive when water temperature reaches to 40oC.

The application of titanium dioxide (TiO2) nanoparticles (NPs) in the manufacturing of consumer products has increased tremendously and with the potential to induce deleterious effects on aquatic biota. There have been reports on metal oxide NP toxicity in aquatic organisms, however, information on cytotoxicity and genotoxicity of TiO2 NPs on the African catfish, Clarias gariepinus, is scarce. In this study, we investigated the genotoxicity and haematotoxicity of TiO2 NPs in C. gariepinus using the micronucleus (MN) assay and haematological analysis, respectively. Juvenile C. gariepinus were exposed to 6.25, 12.5, 25.0, 50.0 and 100.0 mg L−1 concentrations of TiO2 NPs for 7 and 28 days. Benzene (0.05 mL L−1) and dechlorinated tap water were used as positive and negative controls, respectively. Data of the MN showed a significant ( p < 0.05) concentration-dependent increase in the frequency of MN at both exposure periods in comparison to negative control. Red blood cells, haematocrit, platelets and heterophils significantly reduced with an increased mean corpuscular haemoglobin concentration and lymphocytes at the 7-day exposure period, while in the 28-day exposure period, mean cell volume, mean corpuscular haemoglobin and lymphocytes had a significant increase in comparison with the negative control. This study indicates that TiO2 NPs induced cytogenetic and haematological alterations in C. gariepinus and is of relevance in biodiversity and aquatic health management.

The acute and sub-lethal bioassay of aqueous extract of fresh pawpaw (Carica papaya) leaf on Clarias gariepinus fingerlings was investigated. The experiment was carried out at Department of Fisheries Teaching and Research Fish Farm, Modibbo Adama University of Technology Yola. At 96h static bioassay, symptoms of toxicity in the fish indicated that aqueous extract of fresh pawpaw leaf caused sub-acute effects such as altering fish behavior. These behaviors include air gulping, erratic swimming, discoloration, loss of reflex and skin peeling. These behavioral alterations were time and concentration dependent. Exposure to aqueous extract of fresh pawpaw leaf caused decrease in packed cells volume (PCV), haemoglobin (Hb), and red blood cell (RBC), mean corpuscular haemoglobin concentration (MCHC) and an increase in the mean corpuscular haemoglobin (MCH) and mean corpuscular volume (MCV). It resulted in marked increase in white blood cells (WBC). Mortalities and LC50-96h values for Clarias gariepinus exposed to fresh pawpaw leaf extract was (10.9 ml/l). The mortality rates in extracts to Clarias gariepinus in sub-lethal exposure was lower than in acute concentrations. The growth rates were significantly reduced in fish exposed to sub-lethal concentrations of the fresh pawpaw leaf extract compared to the control fish (p<0.05).

The study investigated effects of replacing maize meal with cassava stem meal on growth performance and haematology of African catfish (Clarias gariepinus) fingerlings. Cassava stem meal (CSM) was substituted for maize at 0% (control), 25%, 50%, 75% and 100% to produce five isonitrogenous (45% CP) diets. C. gariepinus fingerlings (mean weight 3.08±0.02g) were randomly distributed into concrete tanks (0.9m3) at 10 fish/tank in triplicates and fed twice daily for 8 weeks. Results showed the highest mean weight gain (1.72±0.01g) and the best food conversion ratio (0.08±0.01) in fish fed diet containing 25% CSM which were significantly different (p<0.05) from other treatments. Fish fed 100% CSM recorded the highest value for protein efficiency ratio which differed significantly (p<0.05) from other treatments. The highest survival rate of (73.3±0.01%) was recorded in fish fed 50% and 100% cassava stem meal inclusion levels while the lowest (33.4±0.01%) was observed in the control diet. The haematological results showed that packed cell volume (PCV), red blood cell (RBC) and haemoglobin (Hb) were significantly different (p<0.05) among treatments. There was an increase in the counts of PCV, white blood cell, Hb, mean corpuscular volume, mean corpuscular haemoglobin while mean corpuscular haemoglobin concentration remained constant in all the treatments. The study revealed that 25% substitution rate of maize with cassava stem meal would not have any adverse effect on the growth and blood parameters of catfish.

The study evaluated sub-lethal toxicity of commercial glyphosate-based Di-ammonium formulation commonly known as ‘Touchdown’ on haematological profile of Clarias gariepinus juveniles. A total of two hundred catfish juveniles of mean weight 31.07±1.23g and mean length 19.50 ± 0.50cm were exposed to different  concentrations of Di-ammonium formulation (1.26, 2.52, 5.03 and 0.00 mg/l) for eight (8) weeks. Each concentration was treated in triplicate using a static bioassay system. Physico-chemical parameters of the test water were monitored throughout the study period. Results showed that haematocrit (HCT), red blood cell (RBC), haemoglobin (HGB), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC) and Platelets (PLT) counts decreased significantly (p<0.05) with increase in concentrations of Touchdown. Whereas, white blood cell (WBC) counts increased significantly (p<0.05) with increasing concentrations of the glyphosate-based formulation. Water temperature, pH, Total dissolved solid (TDS) and electrical conductivity (EC) increased linearly with increasing concentration, while dissolved oxygen content decreased significantly (p<0.05). The results from this study indicated that Di-ammonium glyphosate–based formulation had negative consequences on the blood of treated fish. In view of this, the application of Di-ammonium glyphosate-based formulation should be done in a sustainable manner with proper regulations.

Bioindicator Species

Background. Many natural aquatic bodies have been contaminated with heavy metals released from domestic, industrial and other anthropogenic activities. Fish are an important bioindicator species and play an important role in the monitoring of water pollution. Objectives. This study shows the effect of heavy metals on the distribution of glutathione S-transferases (GST), catalase, rhodanese and 3-mercaptopyruvate sulphur transferase (3-MST) isolated from the liver, gills, fins and muscle of Clarias gariepinus. Methods . Glutathione S-transferase, catalase, rhodanese and 3-mercaptopyruvate S-transferase enzymes were isolated from the liver and gills of fish by homogenization of each tissue (with specific buffers for each enzyme) and centrifugation. Serial dilutions of the crude enzymes were then assayed for residual enzymatic activities using standard enzyme assay protocol. Results. The results showed heavy metals in the liver and muscle of the investigated fish. This study indicated significant accumulation of heavy metals in the tissues/organ of the fish from Ilesha, Osogbo and Yakoyo fish ponds. These are three main towns in Osun State where the major occupation is fish farming. The relationship between enzymatic activities and heavy metal content in C gariepinus tissue showed positive and significant (p&lt;0.05) correlations between lead (Pb) and GST as well as chromium (Cr) and GST. This implies that higher concentrations of Pb and Cr induced the expression of greater GST activity in the fish tissue. Conclusions. The study concluded that the pattern of response of GST, catalase, rhodanese and 3-MST activities in the various organs/tissues of C gariepinus to the heavy metals suggests that the excitation or inhibitions of their activities are organ specific. Further biochemical studies of fish tissues/organs are needed to characterize the enzymatic changes associated with heavy metal pollution.
