In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six food treatments comprising a commercial feed, non-enriched Artemia nauplii and the nauplii enriched by either of fish, sunflower, canola and soybean oils were used in triplicates. The fish fed with Artemia enriched by fish, sunflower and canola oils had significantly higher (p < /em><0.05) survival rate, total length, wet and dry weights, specific growth rate and lower food conversion ratio than those fed the commercial feed. However, there were no significant differences in growth indices between the fish fed fish oil-enriched and plant oil-enriched Artemia. Minimum eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were reported in the fish fed with the commercial feed, while maximum EPA and DHA were in the fish fed canola oil-enriched and nonenriched Artemia, respectively. The fish fed canola oil enriched Artemia had significantly higher (p < /em><0.05) resistance against environmental stresses compared to fish fed the commercial diet.

ZEA was incubated with the hepatic microsomal and post-mitochondrial sub-fractions in the presence of NADPH and the metabolites were determined by means of HPLC. Moreover, the rate of glucuronidation for ZEA and its metabolites were estimated in the presence of uridine diphosphateglucuronic acid. b-zearalenol (b-ZOL) was found to be the major metabolite of ZEA by both sub-fractions.

Data suggest that the hepatic biotransformation of ZEA in studied sturgeons resulted in detoxification of ZEA as the main metabolite tends to be b-ZOL with weaker estrogenic property.
