dc.description.abstractThe aim of the study was to determine the toxic effect of ammonia concentration on juveniles of Palaemon adspersus, a shrimp species important for both fisheries and food webs. Juveniles of P. adspersus were exposed to various ammonia concentrations (NH3) in acute toxicity tests at four pH values (6-9). The 24, 48, 72 and 96-hour LC50 values of total ammonia nitrogen (TAN) ranged from 114.82 to 67.61 mg/dm(3) at pH 6; from 120.23 to 69.18 mg/dm(3) at pH 7; from 87.10 to 54.95 mg/dm(3) at pH 8; from 79.43 to 19.95 mg/dm(3) at pH 9. The 24, 48, 72 and 96-hour LC50 values of NH3-N varied within range of 0.054 to 0.037 mg/dm(3) at pH 6, 0.569 to 0.309 mg/dm(3) at pH 7, 3.846 to 2.291 mg/dm(3) at pH 8 and 24.547 to 6.166 mg/dm(3) at pH 9. It was determined that high pH values noticeably decreased the tolerance of juveniles of P. adspersus to TAN and NH3-N. Mortality rates increased in parallel with increasing NH3 concentrations, pH and exposure time.
