Determining the Effect of Sago Effluent on the Growth Hormone Levels in Clarias batrachus Blood Sample

The aquatic environment is the ultimate sink for all the environmental pollutants any chemical pollutant either natural or synthetic is most likely to reach the aquatic environment sooner or later. The aim of the study was to determine the effect of Sago effluent on the levels of growth hormone in the blood samples of the freshwater fish Clarias batrachus. The fish were exposed to control and different concentrations of treated sago effluents. The concentrations chosen were 25%, 50% and 75% of treated sago effluent. The levels of the growth hormone were increased in the blood sample of the experimental fish Clarias batrachus when compared with that of controls. The findings and the results of the present study indicate that the growth hormone levels in the fish were increased with increasing the concentrations of the effluent. This could be due to some toxicants which is present in effluent could have acted as endocrine disruptors and had a profound influence on the hormone levels.
