Aflatoxins levels in different fish feeds obtained from two different rainbow trout (Oncorhynchus mykiss) farms located in Adana and Ağrı regions were determined between May and July 2017. During the experiment period, ''a drought status'' was reported according to the Standardized Precipitation Index of Turkey by Turkish State Meteorological Service. According to precipitation index records, while Adana was reported as slightly humid, Ağrı was slightly dry in the period between May and July 2017. The aflatoxin analyses of fish feed samples was carried out in the laboratories of the Ministry of Food, Agriculture and Livestock in Adana, Turkey. The aflatoxin levels of the samples were resolved by liquid-solid extraction, immune-affinity pillar clean-up using a HPLC-FD (High Performance Liquid Chromatography with Fluorescence Detection). The detection limits of aflatoxin were 0.50, 0.23, 0.73, 0.20 ppb for AFB1, AFB2, AFG1, AFG2, respectively. The results showed that, aflatoxin levels of fish feeds were below the detection limits in all samples.Aflatoxins levels in different fish feeds obtained from two different rainbow trout (Oncorhynchus mykiss) farms located in Adana and Ağrı regions were determined between May and July 2017.
