Abstract: The physico-chemical parameters of Ikwu River were studied between January and June 2016 in 3 stations to assess its drinking water quality using water quality index. Weighted arithmetic water quality index (WAWQI) method was used. Thirteen parameters were evaluated which included temperature, pH, electrical conductivity (EC), dissolved oxygen, total dissolved solid (TDS), chemical oxygen demand (COD), nitrate, alkalinity, phosphate, sulphate, chloride and calcium. The physico-c...
Diagnosis of parasitic diseases are globally important requisite to realization of wholesome treatment of ailment and reduction in resultant morbidities and mortalities. Parasitic diseases are however hyper- and hypo-prevalent in Nigerian populace often due to socioeconomics factors and ranges of little or no sequels. Low mortality from parasitic infection is due to alternative medication other than successful diagnosis as observed. Subsidizing cost of affording diagnosis, erection of governm...
ABSTRACT The taxonomic composition, abundance and distribution of phytoplankton in Ifewara Reservoir, Southwestern Nigeria was studied for four months (February to December, 2015). Four sampling stations (designated Stations 1-4) were established along the horizontal axis of the reservoir from inflow region to the dam site end. The stations were all sampled at the marginal sides (A and C) and open water B except for Station 1 which was only at the open water. At each station, net plankton sam...
INTRODUCTION Physiological stress and physical injury are the primary contributing factors of fish disease and mortality in aquaculture. Stress is defined as physical or chemical factors that cause bodily reactions that may contribute to disease and death. He further observed that Fishes tend to produce mucus under stressful conditions; any stress causes chemical changes in mucus which decrease its effectiveness as a chemical barrier against invading organisms. Stress upsets the normal electr...
