    Description: Static bioassays were carried out in the laboratory for 96h to investigate the effect of Parateq a synthetic base mud on the fingerling of Orechromis niloticus and their microbial population. The fingerlings were exposed to different concentrations (0, 1000, 3000, 5000 and 9000Mg/l) of drilling fluid. Fish mortality data were recorded at 24, 48, 72 and 96h and analysed using Finney’s Probit Analysis method to calculate LC50 values (concentration of drilling fluid in water that will kill 50% of the fish population in 96 hours). The 96h LC50 was 2210Mg/l.The mortality increased with increase in concentration, while, the lethal times decreased as concentration increased. The bacterial biomass ranged from 1.59 x 108 to 6.0 x 106CFU/ml while fungal biomass ranged from1.0 x 103 to 2.1 x 104 CFU/ml. Results revealed that there was an increase in fungal biomass with increase in mud concentration and a decrease in bacterial biomass with increase in mud concentration.

    Trace metals in water, fish and sediments from Elechi Creek, Port Harcourt, River State, Nigeria (2021)

    Description: The concentration of trace metals: Cadmium (Cd), Lead (Pb), magnesium (Mn), Nickel (Ni) and Zinc (Zn) were determined in water, sediment and fish tissues (S. melanotheron) collected from Elechi creek in Port Harcourt, Nigeria between October and November, 2010. The overall mean concentrations of the trace metals (Mg/g dry weight) in all combined samples ranged from 0.06-0.24 (Cd), 0.59-2.39 (Pb), 0.08-1.15 (Mn), 0.15-0.48 (Ni) and 0.18-7.04 (Zn) respectively. The concentration of the trace metals in water, fish and sediments were in the following order: Pb 〉Ni 〉Zn〉Cd 〉Mn; Zn〉Pb 〉Mn〉Ni 〉Cd and Zn〉 Pb〉Mn〉Ni〉Cd respectively. Except in water, Zinc had the highest value while cadmium had the lowest value. Mn concentration in fish tissue was greater than WHO/FAO certified values. Correlation coefficients between pairs of metals concentration show that all metals positively correlate except Cadmium and Nickel. Elechi creek is not heavily burdened with metals, but aquatic environment should be monitored periodically to avoid excessive intake of trace metals by human.
    Description: Includes: 13 references.
