Using of phytobiotics as fish feed additives have been interestingly increased during the recent decade. The aim of the current study was to evaluate the effect of individual and combined level of thyme and vitamin E in common carp. Juveniles were separately fed by four distinct diets including control (commercial diet without any additive), supplemented with 1% ground Shirazi thyme, supplement...

background: vitamins are considered an essential part in diet of aquatic animals. objectives: this study was carried out to assay the effect of different levels of vitamin e on growth performance, carcass compositions and blood parameters of common carp fingerlings (cyprinus carpio). methods: total number of 96 common carp fingerlings weighing 15.49 ± 3.64 g were randomly distributed into 12 fi...

this research was conducted to evaluate alteration of growth performance, nutrition, carcass and some serum biochemical parameters of common carp fed the diets supplemented by different levels of meal and alcoholic extract of alfalfa (medicago sativa). in this research, 300 fish (mean weight: 20.4 ± 0.19 g and mean length: 11.78 ± 0.64 cm) were fed by nine nutritional diets for 8 weeks. nutriti...

a series of two experiments was conducted to study the optimum dietary protein level and protein to energy ratio of lemon fin barb hybrid larvae. in experiment 1, five isocaloric diets (4700 kcal per kg) ranging from 40 to 60% protein in 5% increments were fed to triplicate groups of lemon fin barb hybrid larvae (initial weight: 0.10 ± 0.01 mg per fish) for 21 days. weight gain of fish was prop...

background: shell is one of the most important by-products of shrimp processing methods which can potentially pollute the environment, whereas shrimp shell contain large amounts of chitin and chitosan and can be used as immune and growth stimulator in aquaculture. objectives: the purpose of present study was to investigate the effect of oral administration of chitosan extracted from litopenaeus...

abstract this investigation was conducted to replace artificial food with gammarus and study this effect on survival and growth parameters of jewel in case of completely randomized design with 3 treatments and 3 replicates in each treatments. 270 jewel fishes with initial mean weight of 1.22±0.72 were reared in 9 aquariums (30 fishes in each aquarium) with volume of 100 liter water. experimenta...
