The present study was designed to evaluate the effects of ethanolic extracts Hypericum perforatum (HP), Origanum vulgare (ORG), and Melissa officinalis (MOF) on Nile tilapia (Oreochromis niloticus) juveniles. Fish (16.92 ± 0.28 g) were randomly divided into seven groups fed diets with 0 % (CTR), two levels (0.2 0.5 %) from each plant extract for 60 days. Final body weight, weight gain %, specific growth rate, feed conversion ratio significantly improved in ORG MOF at (P < 0.05). Moreover,...
The present research explored the effects of Bacillus subtilis on water quality, growth, immune responses, endotoxemia and protection against lipopolysaccharide (LPS) damages in Nile tilapia Oreochromis niloticus under biofloc system. B. was added at 0, 1, 2, 3 4 grams (1.19 × 108 CFU/g) per kg basal diet, named T1 (control), T2, T3, T4 T5, respectively, fed to fish (14.82 ± 0.42 g) for 50 days. concentrations TAN, NO2 NO3 were significantly reduced, probiotics displayed better growth...
The aim of this study was the enrichment high-performance microbial communities in biofilters for removal ammonium and nitrite from aquaculture water. Ammonium oxidizing bacteria (AOB) (NOB) were enriched different environmental water samples. with higher activity selected adapted to temperatures [9 °C, 15 room temperature (25 °C), 30 °C]. expression genes involved nitrification including ammonia monooxygenase (AMO) oxidoreductase (NXR) measured temperature-adapted AOB NOB microbiomes....
Long-day photoperiods are considered as an effective managerial tool in manipulating of reproduction and somatic growth a number fish species. In this study, the effects three different artificial on gonadal development rainbow trout (Oncorhynchus mykiss L.) were investigated. Two years-old immature female (279.94 ±2.25 g) exposed to photoperiod regimes 24L:0D, 18L:6D 6L:18D natural light (NL) regime for 5 months. The highest gonadosomatic indices recorded NL groups while rates significantly...
A morphometric truss network system and meristic counts were used to investigate the hypothesis of population fragmentation pikeperch Sander lucioperca among four major fishing areas in Caspian Sea drainage. Univariate analysis variance showed significant differences between means groups for 20 out 32 standardized measurements (27 truss, five traditional characters) six nine counts. The first two canonical discriminant functions accounted 93 92.3% total variability characteristics,...
In this study, the efficiency of a novel droplet vitrification technique along with different doses fish antifreeze protein (AFP) type III on Persian sturgeon thawed spermatozoa quality (motility duration and motility percentage) was investigated. Semen seven male individuals pooled in equal volumes diluted 4°C Tris-Hcl (100 mM), pH = 8 extenders containing 0, 5, 10, 15 μM AFP ratio 1:1 (semen/extenders). Treated semen dropped into liquid nitrogen. Solidified droplets were stored for 2, 60...
Abstract The aim of this study was isolation and characterization heterotrophic bacteria capable ammonium nitrite removal at 15 °C (optimal temperature for growing rainbow trout Oncorhynchus mykiss ). Environmental isolates were grown in liquid media containing or nitrite, best strains terms growth identified via 16S rRNA sequencing. Dyadobacter sp. (no. 68) Janthinobacterium 100) selected optimal adaptation to ( P < 0.05), respectively. A (HAN) microbial complex, strains, prepared...
A 56-d feeding trial was conducted to investigate the effect of dietary mannan-oligosaccharides (MOS) and fructo-oligosaccharide (FOS) on growth indices, body composition, intestinal bacterial community digestive enzymes activity regal peacock. total 240 fish were randomly distributed 15 experimental units (40-L aquariums) 16 each. These replicates assigned one five treatments in a 2 × + 1 factorial arrangement. The control diet (no MOS FOS), (2 gkg−1 1.5 g kg−1 B 3 C (4 FOS) or D FOS)....
