Acute Toxicity of Fluazifop-P-Butyl (Herbicide) on Oreochromis niloticus(L., 1754) Larvae (Acknowledgements)

Bu çalışmada, Çukurova Bölgesi'nde tarım alanlarında yaygın olarak kullanılan Fluazifop-p-butyl (herbisit)'in Oreochromis niloticus (L.,1754) yavruları üzerine akut toksik etkisi araştırılmıştır. Laboratuvarda 25±2oC'de yürütülen çalışmada, statik biyodeney yöntemi kullanılmış; deneysel sonuçlar log-logistic model istatistik analiz yöntemiyle incelenmiş ve 24 saatlik akut LC50 değeri hesaplanmıştır. Akut toksik etkisi araştırılan Fluazifop-p-butyl (herbisit)'in, Oreochromis niloticus (L.,1754) yavrularına ait 24 saatlik öldürücü konsantrasyon değeri, LC50 1.94±0.02 mgl-1 olarak hesaplanmıştır

Fluazifop-P-Butyl (Herbisit)'in Oreochromis niloticus(L.,1754) Yavruları Üzerine Akut Toksik Etkisinin Araştırılması

In this study, aquatic environments adversely impact, which may occur in order to obtain information about the acute toxicity Fluazifop-p-butyl (herbicide) which is widespread used in agriculture in the Çukurova Region, has been researched using the larvae Oreochromis niloticus (L., 1754). In the present study, the test fish O. niloticus larvae (average weight 1.88±0.6 g, average length 5.04±0.5 cm) were obtained from the Çukurova University Fisheries Faculty Freshwater Fish Research and Application Station. In the experiment, five different concentrations along with the control group were used making a total of 12 aquariums. Each experiment was repeated two times. In this research, the static method of the acute bioassay methods was applied. The experiments were conducted under laboratory conditions at 25±2 oC. The results have been predicted with the dose-response data and were fitted with a log-logistic model by using R 3.0 statistical computation environment and DRC library. The 24-h acute LC value was determined. According to the conclusions, acute toxic effects investigated Fluazifop-p-butyl (herbicide), the 24-h LC50 acute toxic lethal concentration value for Oreochromis niloticus (L., 1754) larvae was calculated to be 1.94±0.02 mgl-1. These results indicate that low levels of Fluazifop-p-butyl (herbicide) in the aquatic environment may have a significant effect on the O. niloticus populations
