The Effect of Two Types of Pesticides, Chemocis ULV and Chemocis D, on the Development, and Hatching of Eggs and Larvae of Common Carp Cyprinus carpio (L.)

Abstract

Abstract This study investigates the effects of two aquatic pollutants, Chemocis ULV and Chemocis D, on the hatching rates and embryonic development of common carp eggs. The experiment employed three different concentrations (5, 10, and 15 ppm) of each compound, along with a control treatment, using the air-hatching technique. The results revealed a significant decrease in hatching rates at concentrations of 10 ppm for both pesticides, reaching 20% and 25%, respectively. The control treatment exhibited the highest hatching percentage, with 96% and 95% for each experiment. Conversely, hatching percentages declined with increasing pollutant concentrations, reaching zero hatching at 15%. The study identified an inverse relationship between egg-hatching time and pesticide concentration for both compounds. Furthermore, the analysis of distortions indicated that the lowest percentage occurred at a concentration of 5 ppm, while the highest was observed at a concentration of 10 ppm. This research contributes valuable insights into the adverse effects of Chemocis ULV and Chemocis D on common carp embryonic development and emphasizes the importance of monitoring and mitigating the impact of such pollutants on aquatic ecosystems.
