- Abstract
Fish farming is a very important commercial sector in Türkiye. The fish produced are exported to abroad rather than the domestic market. The presence of toxic residues in these fish produced for export reduces their commercial value. The use of synthetic anesthetics causes residues in fish to lose their commercial value. The aim of this study is to solve a commercial problem if the mandrake plant is used as an anesthetic in fish instead of synthetic anesthetics that create toxic residues as anesthetic. Since the toxic and lethal doses of mandrake to be used have not been studied before, a new field will be opened with this study. As a result, it was concluded that mandrake plant can be used as an anesthetic. As a result of the test, it was observed that the death rate of Daphnia magna using the extracts prepared by the maceration method was higher than that by the other methods. The highest LC50 value was obtained in the maceration method with 55% concentration and the lowest LC50 value was obtained in the microwave method with 100% concentration. Since the organic matter obtained by the maceration method is at a higher level than that by the other methods, the mortality rate was also higher. As a result, it was concluded that mandrake plant can be used as an anesthetic.
