Using probiotics can control pathogens by a variety of mechanisms. Probiotics can promote growth performance and have, therefore, become increasingly important in the aquaculture industry. Convict Cichlid belongs to the family of Cichlidae and is known for its rapid development in laboratory conditions and is suitable for behavioral examinations. The aim of this study was to evaluate the effect...
this study was accomplished to investigate the effect of artemia urmiana nauplii enriched with pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, huso huso. artemia nauplii were enriched with p. acidilactici at a final concentration of 1010 cfu ml-1 in three time dependent treatments as 3 h (t3), 6 h (t6), 9 h (t9), and one non-enriched artemia as ...
This study was carried out to show the effects of herbal supplement of Sangrovit on the growth parameters, blood biochemical factors, survival and resistance to salinity of the Caspian kutum fry. Fish (1±0.003 g) were divided into four groups fed on diets containing sangrovit at different levels: 0 (control), 0.05, 0.1 and 0.15 % for 45 days. The results showed that there was a significa...
This study was conducted to evaluate the effects of dietary levels of vitamins E (25, 30 and 35 mg kg-1), Folic Acid (1.5, 2 and 2.5 mg kg-1) and their combination on the growth performance, hematological and immunological parameters of rainbow trout, Oncorhynchus mykiss. Each diet was fed to rainbow trout in triplicate to apparent satiation four times daily for 8 weeks. At the end of the feedi...
This study was accomplished to investigate the effect of Artemia urmiana nauplii enriched with Pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, Huso huso. Artemia nauplii were enriched with P. acidilactici at a final concentration of 1010 CFU mL-1 in three time dependent treatments as 3 h (T3), 6 h (T6), 9 h (T9), and one non-enriched Artemia as ...
In this study, the effects of different diets on growth rates of Gammarus Pontogammarous meoticus were determined. A biomass of 1.5 g Gammarus with an average length of 7 ± 0.25 mm was transferred to the glass aquaria with volume 900 cm3 (volume 2.5 l). The Gammarus were fed with diets include baked potato (treatment 1), 30 percent yeast and 70 percent potato, (treatment 2), 50 yeast percent an...
variation in growth, feed utilization and survival was assessed in sturgeon fingerlings of beluga fed different dietary lipid levels. all diets were iso-nitrogenous (protein = 45%) comprising 3.4-3.7 kcal digestible energy g-1. triplicate groups of 35 fingerling beluga with a mean initial wet weight of 2.14 ± 0.07 g (± sd) were fed with four experimental diets containing 6.7, 10.5, 14 and 17% c...
The compensatory growth, proximate composition and amino acid contents changes of young yellow catfish (Pelteobagrus fulvidraco R.) (1.63-1.69 g) had been investigated using a 45-day cyclic feed deprivation and re-feeding experiment. The control group (S0) was fed daily with live tubificid worms (Limnodrilus hoffmeisteri), while the S1/4, S1/2, and S1/1 groups cyclically experienced one-day of ...
