Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. 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 ...

To estimate heritability, and genetic and phenotypic relationships and also to study the effect of sex and rearing environment on body weight, weight gain, feed consumption and feed conversion coefficient, the data from 1200 pedigreed male and female chickens from three genetic groups including 90 sires were used. The included genetic groups were crosses of native chickens and an exotic breed (...

In this study, we divided 300 goldfish (average weight: 12.30 ± 2.11 g) into 4 groups. Fish were fed diets that contained 4 levels of thyme extract: 0 (control), 200, 400 and 800 mg/kg (Thyame, LN23IN, France) for a period of 2 weeks. At the end of 2 weeks, each group of the mentioned treatments was divided into 2 groups: nanosilver-exposed group and control. In the aquarium of the nanosilver-e...

Fluid catalytic cracking (FCC) process is a vital refinery process which majorly produces gasoline. In this research, a hybrid algorithm which was constituted of Adaptive Neuro-Fuzzy Inference System (ANFIS) and firefly optimization algorithm was developed to model the process and optimize the operating conditions. To conduct the research, industrial data of Abadan refinery FCC process were car...
