Physical, Chemical and Periphyton/Phytoplankton Study of Onah Lake, Asaba, Nigeria

Physico-Chemical Characteristics and Phytoplankton Abundance of the Lower Niger River, Kogi State, Nigeria

“…The observed means of DO in the lower Niger River corresponds to the study made by [32]. The high means of DO might be due to abundant oxygen contributed by plants during photosynthetic activity, which contributed in oxygenating the water column and at the same time reducing respiration by aquatic organism and decomposition process at the river bottom [33]. The DO concentration was found to be within the 5mg/L to 9mg/L limit for drinking water [25].…”

Seasonal variation of hepatitis B and C virus infection among HIV- and non-HIV-infected patients in Benin City, Nigeria

“…The second batch of patients, consisting of 564 HIV-positive and 250 non-HIV-positive patients, was enlisted for study during the dry season of the year. In Midwestern Nigeria, the annual dry season spans from October to April, while the rainy season last from May to September, with a characteristic one week August break, in which rainfall abates [12]. Informed consent was obtained from all subjects prior to collection of specimen.…”

Assessment of monthly physico-chemical properties and fish yields of two micro dams of Tigray Region, Northern Ethiopia

“…This is because intensity of metabolism of warm water fish is closely associated with water temperature, that is, the higher the temperature, the higher the metabolic rate (Ovie et al, 2011). Variations in water temperature in the dry season can be attributed to intensified heat radiation and effect of harmattan (Olele and Ekelemu, 2008). Bishat et al (2013) observed wide fluctuation in temperature in earthen pond, cemented ponds and open water body might be due to variation in volume of water.…”

“…TDS concentration below 200 mg/L promoted even healthier spawning conditions (Deepak and Singh, 2014). Imoobe and Oboh (2003) and Olele and Ekelemu (2008) stated the higher TDS value in water bodies during dry season may be due to the evaporation of water and leaving a higher concentration of salt within a smaller volume of water.…”
