| Sumario: | This paper reports the median lethal concentration (LC50-96) of mercury by semi-static acute toxicity test, in Tailand tilapia, Oreochromis niloticus. The challenge was conduct in the Toxicology Laboratory - Instituto de Pesca, SP, with constant temperature. The methods used were those recommended by APHA et al. (1986) and the tests performed with alevins (mean length of 2.46+0.21 cm and mean weight of 0.41+0.12 g). The fish were kept in eighteen 5-liter glass aquaria fill with dischlorinate water plus the mercury of the following concentrations (control, 0.037, 0.185, 0.370, 0.740, 0.925 mg.L-1Hg) during 96 hours. The mortality was registered each 24 hours. Was determined, by the Trimmed Spearman Karber statistic method (HAMILTON et al. 1977). The median lethal concentration (LC50-96) of 0.1961 mg.L-1Hg of mercury for tilapia alevin |
