This study aimed to determine the fat requirement and effect of dietary fat levels on growth and body composition indices of Bester (Huso huso ♀ × Acipenser ruthenus ♂) juveniles( 200.3 ± 2 g) in winter feeding. Fish were fed by 5 isonitrogenous diets (40% crude protein) with different fat levels including 10, 13, 16, 19 and 22%, 3 times daily according to the satiation for 50 days. The results...
Rainbow trout is the most important species of cold water fishes in Iran and the feeding diets which improve the quality and growth of this fish are of great importance. Rainbow trout Oncorhynchus mykiss (n=360) specimens with approximate weight of 2±0.02g were fed with different concentrations of sesame seed in their diet instead of fish meal for 120 days. Feeding diets were prepared in 3 sesa...

Effects of Goldstrip sardine (Sardinella gibossa) and poultry by-product protein hydrolysate on amino acid composition, growth and alevines survival of rainbow trout (Oncorhynchus mykiss) were investigated. Two hydrolyzed protein sources were incorporated into six diets for start-feeding rainbow trout (Oncorhynchus mykiss) alevines, in 3 different replacing levels (10%, 25% and 50%) of fish mea...
This study was conducted to evaluate the effects of four levels of irrigation (irrigation of plants after I1 = 40, I2 =60, I3 = 80 , and I4 = 100mm of evaporation from class A pan) and four plant densities(D1 = 30, D2 = 40, D3 = 50 and D4 = 60 plants/m2) on the seed yield and seed quality in three soybean cultivars(V1=Hobit, V2=Williams and V3=Hill) in a split factorial design, based on the com...

This paper investigates the centralized resource allocation with centralized structures by using the data envelopment analysis-ratio (DEA-R) models. To this end, it proposes a method to determine the resource allocation of centralized structures such that the ratio of inputs to outputs are minimized.
The effects of dietary supplementation of garlic (Allium sativum) extract on the growth and disease resistance of African catfish, Clarias gariepinus was evaluated. Also in-vitro evaluation of susceptibility of fish-borne multidrug resistant (MDR) pathogenic bacteria to aqueous extract of garlic was done. Aqueous garlic extract exhibited inhibitory activity against MDR bacteria and the degree o...
The removal of CO2 through chemical absorption in a bench-scale spray dryer absorber was investigated experimentally using the lime slurry as absorbent. The effect of important operating parameters on CO2 removal efficiency has been investigated; in selected ranges of operating parameters, increasing gas inlet temperature and absorbent concentration lead to permanent efficiency decline, increas...
Following disparity of earlier results, this study tested the performance of African catfish Clarias gariepinus fed dried brewer's yeast slurry meal (DBYM) based diets. Fingerlings of C. gariepinus with pooled mean initial weight of 1.58 ± 0.01 g were stocked in hapas (1 m × 1 m × 1 m) immersed in an earthen pond at a density of 15 fish per cage. Five diets with increasing substitution of soybe...
