Abstract

Pollution is a global problem with hazardous consequences especially on the biotic components of the aquatic ecosystem. Blood is a useful tool in diagnosing the health condition of fish. Hence, the aim of this project was to evaluate the effect of textile wastewater on fish blood. Fish were exposed to varying concentrations of textile wastewater for 96 hours. There were four treatments including the control and others containing 0.0005 ppm, 0.002 ppm and 0.035 ppm of textile wastewater per every 35 litres of freshwater. Each treatment had one replicate with 5 fish stocked in each replicate. The textile effluent significantly reduced (p<0.05) red blood cells (RBC), packed cell volume (PCV), haemoglobin concentration (HGB), and white blood cell (WBC) in the other treatments compared to the control. However, the mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin concentration (MCHC) were not statistically different (p>0.05) from the control. There was a significant reduction in the value of serum metabolites (total protein, globulin, glucose) of juvenile C. gariepinus after exposure to textile effluent (p<0.05). Urea, albumin, and cholesterol increased significantly (p<0.05). However, creatinine did not follow any specific trend across the treatments. The activities of Aspartate transaminase (AST) and Alkaline transaminase (ALT) were significantly higher in the exposed fish compared to the control (p<0.05). Alkaline phosphatase (ALP) recorded a significantly higher value in the control compared to the other treatments (p<0.05). There were no significant differences in the concentrations of both Superoxide dismutase (SOD) and Glutathione S-transferase (GST) of fish exposed to textile effluent (p>0.05). The result revealed that the textile wastewater adversely affected the blood components of the exposed fish. It can be concluded that the presence of textile wastewater in aquatic environments could induce stress and consequently deteriorate the health of aquatic organisms.

Abstract

This study investigated the effects of dietary supplementation with Chasmanthera dependens on the reproductive performance and histopathological health of Clarias gariepinus (African Catfish). A total of 75 healthy adult fish were randomly assigned to five dietary treatments: a control group with no additives and four groups receiving C. dependens at 10g, 20g, 30g, and 40g per kg of feed. The experimental duration lasted 90 days, during which parameters such as sperm quality, egg quality, and histopathological observations of gonads were assessed. Results indicated that the control group exhibited superior sperm quality, including the highest milt volume, motility, and live/dead ratio, compared to all treatment groups. Fecundity, egg size, fertilization rates, and hatchability percentages were also highest in the control group. Conversely, groups receiving higher levels of C. dependens demonstrated significantly lower (p<0.05) reproductive performance metrics, suggesting adverse effects linked to excessive supplementation. Histopathological analysis revealed no observable lesions in the testes and ovaries of the control and lower treatment groups, with healthy seminiferous tubules and advanced vitellogenesis. However, the group receiving the highest level of C. dependens exhibited signs of congestion in the ovaries, indicating potential detrimental effects. Overall, while C. dependens may offer reproductive benefits at moderate levels, excessive dietary inclusion negatively impacted sperm and egg quality as well as gonadal health. Further research is recommended to establish optimal inclusion rates for maximizing the beneficial effects of C. dependens while minimizing adverse impacts on reproductive health.
