Monthly variation in physicochemical parameters of Ebonyi river system

Abstract

Nwabunike, MO

The objectives of the study were to analyze the monthly physic-chemical properties of Ebonyi river system and to make necessary recommendations for the general improvement of fish management in the study area. Stratified random sampling was carried out in each water body. The fishes were caught, identified, counted, graded, measured and weighed according to species. The species for chemical and histological analysis were taken immediately after weighing to the laboratory. It was observed that the mean water temperature of study areas ranged from25.03+0.44 to 29.35+0.44°C. Mkpume River (29.35+0.44°C) had the highest water temperature when compared to that of other study areas (p0.05) but their water temperature were significantly lower than that of pond water (p0.05). There was also not significant difference in the pH of Ameka dam, Mkpuma river and Ebonyi river. The pH of the aforementioned study areas were significantly higher that of pond water (p0.05). The DO of Enyigba river was significantly lower (p0.05). Based on the research findings, the following policy recommendations were therefore proffered. World health/bank should please assist the state Government in making available good quality refined urban tap water to the villages and subborbs so as to save the lives of both Urban and Rural dwellers.
