The aim of the present study was to evaluate the effects of different levels of prebiotic on growth performance and non-specific immune parameters of zebra fish. Four hundred and twenty fish (mean weight 45 ± 0.1 mg) were supplied, randomly stocked in aquaria assigned to four treatments repeated in triplicates and fed with experimental diets contain 0, 0.5, 1 and 2% prebiotic for 8 weeks. At th...

The application of nanotechnology in drug delivery and a variety of supplements is very impressive. In this regard, the use of this knowledge can be effective in the performance of medicinal plants in aquaculture. In the present study Aloe vera was extracted and its nanoparticles were produced. Three levels of Aloe vera nanoparticles in Siberian sturgeon (Acipenser baerii) were evaluated for th...

This study was carried out to determine the effects of Immunogen as a prebiotic on growth-related parameters and gut micro-flora in R. kutum fry. A basal diet was formulated using common feed ingredients supplemented with Immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets.  Fish were randomly distributed in 500 L fiberglass tanks (1×1×0.5 m). The experiment lasted for eight ...

The aim of this study was to determine the effect of anthocyanin from roselle (Hibiscus sabdariffa) supplemented diets on growth, survival and body composition of rainbow trout (Oncorhynchus mykiss) for 60 days. Fish were fed 0 % (control), 0.5 %, 1 %  and 2 % anthocyanin extract in complete random design.  Fifteen fish with the same initial weight (14 ± 0. 1 g) were selected and randomly distr...

A new isolated strain of Sporobolomyces ruberrimus H110 was cultivated  on technical glycerol as carbon source and effect of different temperatures and pH on the growth and pigmentation was studied. The maximum concentration of total carotenoid was 3.84 mgg-1 including torularhodin (3.70 mgg-1) and β-carotene (0.14 mgg-1) using 19ºC at pH 6, but the highest ...

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...

Biodesulfurization of coal has been carried out in batch culture of single strain and mixed culture of sulfur oxidizing bacteria. The pure cultures of Thiobacillus thiooxidans and Thiobacillus ferrooxidans utilized inorganic sulfur content of Malaysian coal. The chemolithotroph bacteria were able to grow on coal and metabolize the coal's sulfur content. The batch cultures of coal with 3-5 perce...
