Resumen:
Abstract: The effects of sodium chloride (NaCl) and formalin (F) on some
toxicological parameters and the hatching rate of Odontesthes bonariensis eggs
were examined under laboratory conditions, and the determined values were
compared with those obtained for Malachite Green (MG), which was used as a
reference toxic. The 96 hours nominal LC50 were 1.51 mg L−1, 652.14 μl L−1
and 34.82 g L−1 for MG, F and NaCl, respectively. The No-Observed-Effect
Concentration (NOEC) and the No-Effect Concentrations (NEC) were
1.5 mg L−1 and 0.507 mg L−1 (MG), 400 μl L−1 and 530 μl L−1 (F) and
30.0 g L−1 and 28.68 g L−1 (NaCl), respectively. Hatching rates of 60% or
higher were determined for eggs after 168 hours incubation in the assayed
solutions at concentrations of 0.75 mg L−1 (MG), 300 μ L−1 (F) and 20 g L−1
(NaCl); at higher concentrations the hatching rates were severely affected.
