this study was conducted to evaluate the effects of beta plus probiotic, a mixture of bacillius leicheniformic and bacillius subtilis , on the growth performance and intestinal microbial flora of caspian trout ( salmo caspius ). a basal diet was formulated and supplemented with beta plus at 0, 0.5 and 1 g kg -1 , leading to three experimental diets. each experimental diet was randomly assigned ...

this experiment was conducted in international researchery institute of sturgeon fishes shahid  dadman. the basal diet contained fish meal as protein source (cp=40%). five diets were supplemented with 5 graded levels of methionine, (0, 0.5,1 ,1.5, 2% met per kg diet) . each diet was randomly assigned to triplicate groups of 195 juvenile huso huso (initial weight 31.9± 2.8) in fiftin 500-l circu...

The experiment was conducted to determine the effects of different photoperiods and darkness on the growth and survival of juvenile Catla catla in the laboratory for 90 days. Fishes were divided into four aquaria (10 fish per aquarium), and subjected to different photoperiod regimes of 8 hours light: 16 hours dark (8L:16D), 16 hours light: 8 hours dark (16L:8D), continuous light (24L:0D) and co...

Key word: Growth promoter, mono-sex Tilapia, production, probiotic, FCR, SGR The present study was conducted in farmer’s ponds at field level of Muktagachha upazilla to find out the effect of growth promoter on growth performance and feed utilization of monosex Tilapia fish. Growth promoter was used in the experimental cultured farm. This growth enhancing aqua drugs was used in feeds of Tilapia...

in this study, two main probiotics (lactobacillus plantarum and lactobacillus delbrueckii subsp. bulgaricus) were isolated from the intestine of tor grypus and their effects on growth performance, gut microbial flora and digestive enzymes activities (i.e., α-amylase, lipase, trypsin, chymotrypsin, and alkaline phosphatase) of tor grypus (karaman, 1971) were determined. juveniles of t. grypus (n...

The purpose of this study was to apply high-wattage pulsed irradiation of linearly polarized near-infrared light to the stellate ganglion area for burning mouth syndrome (BMS) and to assess the efficacy of the stellate ganglion area irradiation (SGR) on BMS using differential time-/frequency-domain parameters (D parameters). Three patients with BMS received high-wattage pulsed SGR; the response...

An 11-week feeding trial was conducted to assess the dietary lysine requirement for juvenile Hemibagrus wyckioides. Six isoproteic and isoenergetic diets (41.66% crude protein, 20.56 kJ/g gross energy) containing 1.1%, 1.5%, 1.9%, 2.3%, 2.7%, 3.1% were prepared feed juveniles (average initial body weights of 1.25 g), respectively. The weight gain, specific growth rate (SGR), conversion ratio (F...

Levels of dietary carbohydrates and lipids have important effects on the growth, health, glycolipid metabolizing capacity hybrid grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatus ♂). This experiment evaluated effect carbohydrate to lipid ratios (CHO:L ratio) serum biochemical indices, intestinal morphology activity digestive enzymes, ability metabolize in grouper. Six iso-nitrogenous (500 g...

Marine sponges are a rich source of bioactive metabolites that can potentially be used as lead compounds to treat various human diseases. Due to the difficulty in obtaining a steady supply of such metabolites, few of these compounds have reached the clinical trials stage. Sponge sea ranching is one of the most promising methods to overcome this bsupply problemQ. The Red Sea sponge Negombata mag...
