Toxicity of oil-based drilling mud (OBM) on the survival of the fingerlings of Niger Delta mudskipper, Periophthalmus papilio (Boch and Schneider, 1801)
The toxicity of oil - based drilling mud on the survival of the fingerlings of Niger Delta mudskipper, Periophthalmus papilio were studied using static plastic tanks. The exposure period lasted for 96 hours. Lethal concentration (LC50) and lethal time (LT50) were determined. The control tanks contained no oil- based drilling mud. Results revealed increased in mortality values of the fish to all lethal concentrations. There was no mortality observed in the control tank. The oil- based drilling mud were toxic on Periopthalmus papilio.
