Abstract


This study investigates the use of the fish embryo toxicity test on early life stages of Pachychilon pictum, obtained from wild populations in Lake Ohrid. Various chemical compounds were assessed for mortality, and median lethal concentrations at 96h post fertilization were determined. The findings demonstrated the successful application of the test requirements, confirming that embryos of this species are suitable for toxicity testing. Notably, this represents the first ever toxicological investigation conducted on a fish species from Lake Ohrid, highlighting the importance of the resulting data.
