  The effect of Dimethoate on oxidative stress and antioxidant responses of Pontastacus leptodactylus; [El efecto del dimetoato sobre el estrés oxidativo y las respuestas antioxidantes de Pontastacus leptodactylus]

  Aydın, Ayşe Nur; Bulut, Hilal; Serdar, Osman

  Dimethoate (DMT) pesticide is one of the chemicals used to protect some agricultural areas from harmful organisms. DMT residues released directly or indirectly to the environment cause serious problems in nature. DMT residues mixed with the aquatic environment adversely affect aquatic organisms and this effect is carried to humans through the food chain. In this study, oxidative stress responses induced by DMT pesticide in Pontastacus leptodactylus were investigated. For this purpose, oxidative stress and antioxidant parameters Thiobarbituric acid reactive substances (TBARS), Glutathione (GSH), Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) caused by dimethoate (DMT) pesticide in P. leptodactylus at 17.5, 35, and 70 mg·L-1 concentrations at 24 and 96 hours were investigated. Results were determined using ELISA kits. No significant difference was observed in GSH levels and SOD activities compared to control. Statistically significant differences were observed between decreases in CAT and GPx activities and increases in TBARS levels. SPSS 24.0 package program one–way ANOVA (Duncan 0.05) was used in the evaluation of biochemical analyzes. As a result, it was determined that DMT caused oxidative stress formation in P. leptodactylus and caused changes in enzyme activities.

  Current Status of Aquarium Fish (Ornamental Fish) Enterprises During the \rPandemic Period (Elazig City Sample)

  Ozcan, Ebru Ifakat; Bulut, Hilal

  This study was carried out in order to reveal the situation of aquarium sales enterprises in Elazig and \rto determine their problems. In the study, a total of 14 enterprises (aquarist) were asked questions by \rthe survey method. It has been determined that a significant part of the existing enterprises is located \rin the center of Elazig (93%), all of them continue to operate as tenants and their operating periods \rare over 5 years. It has been noted that 86% of the personnel working in the enterprises are male and \r14% are female. It was determined that the most sold fish species in the research area were 2 fish \rspecies belonging to 2 families. It has been observed that one of the important problems in aquarium \rbusinesses is fish diseases. It has been determined that 93% of the fish sales of the Covid-19 pandemic \rperiod were negatively affected and 7% were positively affected.\r
