摘要：

The average lethal concentration of un-ionized ammonia (48-h LC(50)NH(3)) has been determined by the static assay for larvae (0.48 mg l(-1)) and alevins (0.92 mg l(-1)) of 'pacama' Lophiosilurus alexandri. Studies by light and scanning electron microscopes at the greatest concentration of NH3 (0.99 mg l(-1) for larvae and 1.5 mg l(-1) for alevins) have shown that the changes in the cells and branchial tissue were moro intense in the alevins.
