The effect of mercury on the growth efficiency of Tilapia mossambica (Peters)
Menezes, M.R.; Qasim, S.Z. (Indian Association for Limnology and Oceanography, 1984)Three concentrations of mercury (0.01, 0.04 and 0.4 ppm) were used for experiments on growth efficiency of Tilapia mossambica. Growth efficiencies were determined on a dry weight basis. High concentration of mercury (0.4 ... -
