phenol and its homologues are aromatics containing hydroxyl, methyl, amide and sulphonic groups attached to the benzene ring. these molecules are both anthropogenic and xenobiotics. phenols are environmental pollutants discharged through wastewaters from various industries. phenols are toxic to several biochemical reactions. however biological transformation of phenols to non-toxic entities exi...

this study was conducted to evaluate the effects of different proportions of lemon bee brush essential oil on growth performance, carcass composition, and hematology and biochemical parameters of common carp (cyprinus carpio). common carp with an average weight of 8 ± 0.2 g were fed for one month with a diet supplemented with lemon beebrush essential oil (0.15 and 0.3 ml) and with normal diet a...

This study was carried out to investigate the effect of replacing fish meal protein with fermented soybean meal (FSM) in diets on growth performance, feed utilization, morphological parameters, body composition, activities of antioxidant and digestive enzymes and also blood biochemistry of juvenile olive flounder (Paralichthys olivaceus). Five isonitrogenic and isolipidic diets were prepare...

This study was conducted to evaluate the effect of different levels of dietary supplementation of Saccharomyces cerevisiae on growth performance, feed utilization and body biochemical composition of Oreochromis niloticus fingerlings. Four diets containing supplementation at levels of 0, 0.5, 1 and 2 g kg−1 were fed to fingerlings of Nile tilapia (5.01±0.21 g) in four replicate tanks twice ...

this study was carried out to investigate the effects of salinity levels (0, 2, 4, 7 and 10 ppt) on growth indices, blood biochemical parameters, and body composition in rutilus frisii kutum fingerlings (initial weight 1.330.02 g) during 60 days. results indicated that the highest rates of daily growth, specific growth and weight gain per fish were obtained at the levels of 4 and 2 ppt (p0.05)...

this study surveys on the effects of l-lysine and methionon amino acids on growth performance, survival rate and body composition of rainbow trout (oncorhynchus mykiss). fish with initial average weight 105.23 +  6.33 g in 5 treatments fed with different levels of lysine (1 and 3 %) and methionine ( 1 and 2%) for 8 weeks. the results showed that the treatment which fed 2 % methionine had the be...

Effects of Pure and Mixed substrates on nutritional composition, minerals and growth of Oyster Mushroom (Pleurotus ostreatus) were studied in present study. Results of the study revealed that the total protein content, ash, crude fiber and crude fat were higher in the mushroom harvested from mixed substrate (23.64, 8.17, 0.90 and 2.93%nrespectively) than that of the pure substrates (21.02, 3.40...
