The average lethal concentration of un-ionized ammonia (48-h LC50NH3) has been determined by the static assay for larvae (0.48 mgl-1) and alevins (0.92 mgl-1) of pacama Lophiosilurus alexandri. Studies by light and scanning electron microscopes at the greatest concentrations 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 more intense in the alevins. |
